1.	Klionsky, Daniel J., et al. (author) Guidelines for the use and interpretation of assays for monitoring autophagy 2012 In: Autophagy. - : Informa UK Limited. - 1554-8635 .- 1554-8627. ; 8:4, s. 445-544 Research review (peer-reviewed)abstract In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. A key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process vs. those that measure flux through the autophagy pathway (i.e., the complete process); thus, a block in macroautophagy that results in autophagosome accumulation needs to be differentiated from stimuli that result in increased autophagic activity, defined as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (in most higher eukaryotes and some protists such as Dictyostelium) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the field understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field.
2.	Pennells, Lisa, et al. (author) Equalization of four cardiovascular risk algorithms after systematic recalibration : individual-participant meta-analysis of 86 prospective studies 2019 In: European Heart Journal. - : Oxford University Press (OUP). - 0195-668X .- 1522-9645. ; 40:7, s. 621- Journal article (peer-reviewed)abstract Aims: There is debate about the optimum algorithm for cardiovascular disease (CVD) risk estimation. We conducted head-to-head comparisons of four algorithms recommended by primary prevention guidelines, before and after ‘recalibration’, a method that adapts risk algorithms to take account of differences in the risk characteristics of the populations being studied.Methods and results: Using individual-participant data on 360 737 participants without CVD at baseline in 86 prospective studies from 22 countries, we compared the Framingham risk score (FRS), Systematic COronary Risk Evaluation (SCORE), pooled cohort equations (PCE), and Reynolds risk score (RRS). We calculated measures of risk discrimination and calibration, and modelled clinical implications of initiating statin therapy in people judged to be at ‘high’ 10 year CVD risk. Original risk algorithms were recalibrated using the risk factor profile and CVD incidence of target populations. The four algorithms had similar risk discrimination. Before recalibration, FRS, SCORE, and PCE over-predicted CVD risk on average by 10%, 52%, and 41%, respectively, whereas RRS under-predicted by 10%. Original versions of algorithms classified 29–39% of individuals aged ≥40 years as high risk. By contrast, recalibration reduced this proportion to 22–24% for every algorithm. We estimated that to prevent one CVD event, it would be necessary to initiate statin therapy in 44–51 such individuals using original algorithms, in contrast to 37–39 individuals with recalibrated algorithms.Conclusion: Before recalibration, the clinical performance of four widely used CVD risk algorithms varied substantially. By contrast, simple recalibration nearly equalized their performance and improved modelled targeting of preventive action to clinical need.
3.	Büchner, Frederike L, et al. (author) Variety in vegetable and fruit consumption and risk of bladder cancer in the European prospective investigation into cancer and nutrition 2011 In: International Journal of Cancer. - : Wiley. - 0020-7136 .- 1097-0215. ; 128:12, s. 2971-2979 Journal article (peer-reviewed)abstract Recent research does not show an association between fruit and vegetable consumption and bladder cancer risk. None of these studies investigated variety in fruit and vegetable consumption, which may capture different aspects of consumption. We investigated whether a varied consumption of vegetables and fruits is associated with bladder cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Detailed data on food consumption and complete follow-up for cancer incidence were available for 452,185 participants, who were recruited from ten European countries. After a mean follow-up of 8.7 years, 874 participants were diagnosed with bladder cancer. Diet diversity scores (DDSs) were used to quantify the variety in fruit and vegetable consumption. Multivariable Cox proportional hazard models were used to assess the effect of the DDSs on bladder cancer risk. There was no evidence of a statistically significant association between bladder cancer risk and any of the DDSs when these scores were considered as continuous covariates. However, the hazard ratio (HR) for the highest tertile of the DDS for combined fruit and vegetable consumption was marginally significant compared to the lowest (HR = 1.30, 95% confidence interval: 1.00-1.69, p-trend = 0.05). In EPIC, there is no clear association between a varied fruit and vegetable consumption and bladder cancer risk. This finding provides further evidence for the absence of any strong association between fruit and vegetable consumption as measured by a food frequency questionnaire and bladder cancer risk.
4.	Buechner, Frederike L., et al. (author) Consumption of vegetables and fruit and the risk of bladder cancer in the European Prospective Investigation into Cancer and Nutrition 2009 In: International Journal of Cancer. - : Wiley. - 0020-7136 .- 1097-0215. ; 125:11, s. 2643-2651 Journal article (peer-reviewed)abstract Previous epidemiologic studies found inconsistent associations between vegetables and fruit consumption and the risk of bladder cancer. We therefore investigated the association between vegetable and fruit consumption and the risk of bladder cancer among participants of the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Data on food consumption and complete follow-up for cancer occurrence was available for a total of 478,533 participants, who were recruited in 10 European countries. Estimates of rate ratios were obtained by Cox proportional hazard models, stratified by age at recruitment, gender and study centre, and adjusted for total energy intake, smoking status, duration of smoking and lifetime intensity of smoking. A calibration study in a subsample was used to control for dietary measurement errors. After a mean follow-up of 8.7 years, 1015 participants were newly diagnosed with bladder cancer. Increments of 100 g/day in fruit and vegetable consumption combined did not affect bladder cancer risk (i.e., calibrated HR = 0.98; 95%CI: 0.95-1.01). Borderline statistically significant lower bladder cancer risks were found among fever smokers with increased consumption of fruit and vegetables combined (HR = 0.94 95%CI: 0.87-1.00 with increments of 100 g/day; calibrate HR = 0.92 95%CI 0.79-1.06) and increased consumption of apples and pears (hard fruit; calibrated HR = 0.90 95%CI: 0.82-0.98 with increments of 25 g/day). For none of the associations a statistically significant interaction with smoking status was found. Our findings do not support an effect of fruit and vegetable consumption, combined or separately, on bladder cancer risk. (c) 2009 UICC
5.	Di Angelantonio, Emanuele, et al. (author) Association of Cardiometabolic Multimorbidity With Mortality : The Emerging Risk Factors Collaboration 2015 In: Journal of the American Medical Association (JAMA). - : American Medical Association (AMA). - 0098-7484 .- 1538-3598. ; 314:1, s. 52-60 Journal article (peer-reviewed)abstract IMPORTANCE The prevalence of cardiometabolic multimorbidity is increasing.OBJECTIVE To estimate reductions in life expectancy associated with cardiometabolic multimorbidity.DESIGN, SETTING, AND PARTICIPANTS Age-and sex-adjusted mortality rates and hazard ratios (HRs) were calculated using individual participant data from the Emerging Risk Factors Collaboration (689 300 participants; 91 cohorts; years of baseline surveys: 1960-2007; latest mortality follow-up: April 2013; 128 843 deaths). The HRs from the Emerging Risk Factors Collaboration were compared with those from the UK Biobank (499 808 participants; years of baseline surveys: 2006-2010; latest mortality follow-up: November 2013; 7995 deaths). Cumulative survival was estimated by applying calculated age-specific HRs for mortality to contemporary US age-specific death rates. EXPOSURES A history of 2 or more of the following: diabetes mellitus, stroke, myocardial infarction (MI).MAIN OUTCOMES AND MEASURES All-cause mortality and estimated reductions in life expectancy.RESULTS In participants in the Emerging Risk Factors Collaboration without a history of diabetes, stroke, or MI at baseline (reference group), the all-cause mortality rate adjusted to the age of 60 years was 6.8 per 1000 person-years. Mortality rates per 1000 person-years were 15.6 in participants with a history of diabetes, 16.1 in those with stroke, 16.8 in those with MI, 32.0 in those with both diabetes and MI, 32.5 in those with both diabetes and stroke, 32.8 in those with both stroke and MI, and 59.5 in those with diabetes, stroke, and MI. Compared with the reference group, the HRs for all-cause mortality were 1.9 (95% CI, 1.8-2.0) in participants with a history of diabetes, 2.1 (95% CI, 2.0-2.2) in those with stroke, 2.0 (95% CI, 1.9-2.2) in those with MI, 3.7 (95% CI, 3.3-4.1) in those with both diabetes and MI, 3.8 (95% CI, 3.5-4.2) in those with both diabetes and stroke, 3.5 (95% CI, 3.1-4.0) in those with both stroke and MI, and 6.9 (95% CI, 5.7-8.3) in those with diabetes, stroke, and MI. The HRs from the Emerging Risk Factors Collaboration were similar to those from the more recently recruited UK Biobank. The HRs were little changed after further adjustment for markers of established intermediate pathways (eg, levels of lipids and blood pressure) and lifestyle factors (eg, smoking, diet). At the age of 60 years, a history of any 2 of these conditions was associated with 12 years of reduced life expectancy and a history of all 3 of these conditions was associated with 15 years of reduced life expectancy.CONCLUSIONS AND RELEVANCE Mortality associated with a history of diabetes, stroke, or MI was similar for each condition. Because any combination of these conditions was associated with multiplicative mortality risk, life expectancy was substantially lower in people with multimorbidity.
6.	Hoeft, Birgit, et al. (author) Polymorphisms in fatty acid metabolism-related genes are associated with colorectal cancer risk 2010 In: Carcinogenesis. - : Oxford University Press (OUP). - 0143-3334 .- 1460-2180. ; 31:3, s. 466-472 Journal article (peer-reviewed)abstract Colorectal cancer (CRC) is the third most common malignant tumor and the fourth leading cause of cancer death worldwide. The crucial role of fatty acids for a number of important biological processes suggests a more in-depth analysis of inter-individual differences in fatty acid metabolizing genes as contributing factor to colon carcinogenesis. We examined the association between genetic variability in 43 fatty acid metabolism-related genes and colorectal risk in 1225 CRC cases and 2032 controls participating in the European Prospective Investigation into Cancer and Nutrition study. Three hundred and ninety two single-nucleotide polymorphisms were selected using pairwise tagging with an r(2) cutoff of 0.8 and a minor allele frequency of > 5%. Conditional logistic regression models were used to estimate odds ratios and corresponding 95% confidence intervals. Haplotype analysis was performed using a generalized linear model framework. On the genotype level, hydroxyprostaglandin dehydrogenase 15-(NAD) (HPGD), phospholipase A2 group VI (PLA2G6) and transient receptor potential vanilloid 3 were associated with higher risk for CRC, whereas prostaglandin E receptor 2 (PTGER2) was associated with lower CRC risk. A significant inverse association (P < 0.006) was found for PTGER2 GGG haplotype, whereas HPGD AGGAG and PLA2G3 CT haplotypes were significantly (P < 0.001 and P = 0.003, respectively) associated with higher risk of CRC. Based on these data, we present for the first time the association of HPGD variants with CRC risk. Our results support the key role of prostanoid signaling in colon carcinogenesis and suggest a relevance of genetic variation in fatty acid metabolism-related genes and CRC risk.

8.	Rohrmann, Sabine, et al. (author) Ethanol intake and risk of lung cancer in the European prospective investigation into cancer and nutrition (EPIC) 2006 In: American Journal of Epidemiology. - : Oxford University Press (OUP). - 0002-9262 .- 1476-6256. ; 164:11, s. 1103-1114 Journal article (peer-reviewed)abstract Within the European Prospective Investigation into Cancer and Nutrition (EPIC), the authors examined the association of ethanol intake at recruitment (1,119 cases) and mean lifelong ethanol intake (887 cases) with lung cancer. Information on baseline and past alcohol consumption, lifetime tobacco smoking, diet, and the anthropometric characteristics of 478,590 participants was collected between 1992 and 2000. Cox proportional hazards regression was used to calculate multivariate-adjusted hazard ratios and 95% confidence intervals. Overall, neither ethanol intake at recruitment nor mean lifelong ethanol intake was significantly associated with lung cancer. However, moderate intake (5-14.9 g/day) at recruitment (hazard ratio (HR) = 0.76, 95% confidence interval (CI): 0.63, 0.90) and moderate mean lifelong intake (HR = 0.80, 95% CI: 0.66, 0.97) were associated with a lower lung cancer risk in comparison with low consumption (0.1-4.9 g/day). Compared with low intake, a high (>= 60 g/day) mean lifelong ethanol intake tended to be related to a higher risk of lung cancer (HR = 1.29, 95% CI: 0.93, 1.74), but high intake at recruitment was not. Although there was no overall association between ethanol intake and risk of lung cancer, the authors cannot rule out a lower risk for moderate consumption and a possibly increased risk for high lifelong consumption.
9.	Ros, Martine M., et al. (author) Fluid intake and the risk of urothelial cell carcinomas in the European Prospective Investigation into Cancer and Nutrition (EPIC) 2011 In: International Journal of Cancer. - : Wiley. - 0020-7136 .- 1097-0215. ; 128:11, s. 2695-2708 Journal article (peer-reviewed)abstract Results from previous studies investigating the association between fluid intake and urothelial cell carcinomas (UCC) are inconsistent. We evaluated this association among 233,236 subjects in the European Prospective Investigation into Cancer and Nutrition (EPIC), who had adequate baseline information on water and total fluid intake. During a mean follow-up of 9.3 years, 513 first primary UCC occurred. At recruitment, habitual fluid intake was assessed by a food frequency questionnaire. Multivariable hazard ratios were estimated using Cox regression stratified by age, sex and center and adjusted for energy intake, smoking status, duration of smoking and lifetime intensity of smoking. When using the lowest tertile of intake as reference, total fluid intake was not associated with risk of all UCC (HR 1.12; 95% CI 0.86-1.45, p-trend = 0.42) or with risk of prognostically high-risk UCC (HR 1.28; 95% CI 0.85-1.93, p-trend = 0.27) or prognostically low-risk UCC (HR 0.93; 95% CI 0.65-1.33, p-trend = 0.74). No associations were observed between risk of UCC and intake of water, coffee, tea and herbal tea and milk and other dairy beverages. For prognostically low-risk UCC suggestions of an inverse association with alcoholic beverages and of a positive association with soft drinks were seen. Increased risks were found for all UCC and prognostically low-risk UCC with higher intake of fruit and vegetable juices. In conclusion, total usual fluid intake is not associated with UCC risk in EPIC. The relationships observed for some fluids may be due to chance, but further investigation of the role of all types of fluid is warranted.

11.	Adamopoulos, Stamatis, et al. (author) Exercise training in patients with ventricular assist devices: a review of the evidence and practical advice. A position paper from the Committee on Exercise Physiology and Training and the Committee of Advanced Heart Failure of the Heart Failure Association of the European Society of Cardiology 2019 In: European Journal of Heart Failure. - : WILEY. - 1388-9842 .- 1879-0844. ; 21:1 Research review (peer-reviewed)abstract Exercise training (ET) and secondary prevention measures in cardiovascular disease aim to stimulate early physical activity and to facilitate recovery and improve health behaviours. ET has also been proposed for heart failure patients with a ventricular assist device (VAD), to help recovery in the patients functional capacity. However, the existing evidence in support of ET in these patients remains limited. After a review of current knowledge on the causes of the persistence of limitation in exercise capacity in VAD recipients, and concerning the benefit of ET in VAD patients, the Heart Failure Association of the European Society of Cardiology has developed the present document to provide practical advice on implementing ET. This includes appropriate screening to avoid complications and then starting with early mobilisation, ET prescription is individualised to meet the patients needs. Finally, gaps in our knowledge are discussed.
12.	Aktaa, Suleman, et al. (author) Data standards for heart failure : the European Unified Registries for Heart Care Evaluation and Randomized Trials (EuroHeart) 2022 In: European Heart Journal. - : Oxford University Press. - 0195-668X .- 1522-9645. ; 43:23, s. 2185- Journal article (peer-reviewed)abstract Standardized data definitions are essential for assessing the quality of care and patient outcomes in observational studies and randomized controlled trials. The European Unified Registries for Heart Care Evaluation and Randomized Trials (EuroHeart) project of the European Society of Cardiology (ESC) aims to create contemporary pan-European data standards for cardiovascular diseases, including heart failure (HF). We followed the EuroHeart methodology for cardiovascular data standard development. A Working Group including experts in HF registries, representatives from the Heart Failure Association of the ESC, and the EuroHeart was formed. Using Embase and Medline (2016-21), we conducted a systematic review of the literature on data standards, registries, and trials to identify variables pertinent to HF. A modified Delphi method was used to reach a consensus on the final set of variables. For each variable, the Working Group developed data definitions and agreed on whether it was mandatory (Level 1) or additional (Level 2). In total, 84 Level 1 and 79 Level 2 variables were selected for nine domains of HF care. These variables were reviewed by an international Reference Group with the Level 1 variables providing the dataset for registration of patients with HF on the EuroHeart IT platform. By means of a structured process and interaction with international stakeholders, harmonized data standards for HF have been developed. In the context of the EuroHeart, this will facilitate quality improvement, international observational research, registry-based randomized trials, and post-marketing surveillance of devices and pharmacotherapies across Europe.
13.	Bandak, Ghassan, et al. (author) Hyperkalemia After Initiating Renin-Angiotensin System Blockade : The Stockholm Creatinine Measurements (SCREAM) Project 2017 In: Journal of the American Heart Association. - : WILEY. - 2047-9980. ; 6:7 Journal article (peer-reviewed)abstract Background: Concerns about hyperkalemia limit the use of angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin receptor blockers (ARBs), but guidelines conflict regarding potassium-monitoring protocols. We quantified hyperkalemia monitoring and risks after ACE-I/ARB initiation and developed and validated a hyperkalemia susceptibility score.Methods and Results: We evaluated 69 426 new users of ACE-I/ARB therapy in the Stockholm Creatinine Measurements (SCREAM) project with medication initiation from January 1, 2007 to December 31, 2010, and follow-up for 1 year thereafter. Three fourths (76%) of SCREAM patients had potassium checked within the first year. Potassium >5 and >5.5 mmol/L occurred in 5.6% and 1.7%, respectively. As a comparison, we propensity-matched new ACE-I/ARB users to 20 186 new beta-blocker users in SCREAM: 64% had potassium checked. The occurrence of elevated potassium levels was similar between new beta-blocker and ACEI/ARB users without kidney disease; only at estimated glomerular filtration rate <60 mL/min per 1.73 m(2) were risks higher among ACE-I/ARB users. We developed a hyperkalemia susceptibility score that incorporated estimated glomerular filtration rate, baseline potassium level, sex, diabetes mellitus, heart failure, and the concomitant use of potassium-sparing diuretics in new ACE-I/ARB users; this score accurately predicted 1-year hyperkalemia risk in the SCREAM cohort (area under the curve, 0.845, 95% CI: 0.840-0.869) and in a validation cohort from the US-based Geisinger Health System (N=19 524; area under the curve, 0.818, 95% CI: 0.794-0.841), with good calibration.Conclusions: Hyperkalemia within the first year of ACE-I/ARB therapy was relatively uncommon among people with estimated glomerular filtration rate >60 mL/min per 1.73 m(2), but rates were much higher with lower estimated glomerular filtration rate. Use of the hyperkalemia susceptibility score may help guide laboratory monitoring and prescribing strategies.
14.	Bank, Ingrid E. M., et al. (author) Prevalence and Clinical Significance of Diabetes in Asian Versus White Patients With Heart Failure 2017 In: JACC. Heart failure. - : ELSEVIER SCI LTD. - 2213-1779 .- 2213-1787. ; 5:1, s. 14-24 Journal article (peer-reviewed)abstract OBJECTIVES The study sought to compare the prevalence, clinical correlates and prognostic impact of diabetes in Southeast Asian versus white patients with heart failure (HF) with preserved or reduced ejection fraction. BACKGROUND Diabetes mellitus is common in HF and is associated with impaired prognosis. Asia is home to the majority of the worlds diabetic population, yet data on the prevalence and clinical significance of diabetes in Asian patients with HF are sparse, and no studies have directly compared Asian and white patients. METHODS Two contemporary population-based HF cohorts were combined: from Singapore (n 1,002, median [25th to 75th percentile] age 62 [54 to 70] years, 76% men, 19.5% obesity) and Sweden (n =19,537, 77 [68 to 84] years, 60% men, 24.8% obesity). The modifying effect of ethnicity on the relationship between diabetes and clinical correlates or prognosis (HF hospitalization and all-cause mortality) was examined using interaction terms. RESULTS Diabetes was present in 569 (57%) Asian patients versus 4,680 (24%) white patients (p amp;lt; 0.001). Adjusting for clinical covariates, obesity was more strongly associated with diabetes in white patients (odds ratio [OR]: 3.45;. 95% confidence interval [CI]: 2.86 to 4.17) than in Asian patients (OR: 1.82; 95% CI: 1.13 to 2.96; P-interaction = 0.026). Diabetes was more strongly associated with increased HF hospitalization and all-cause mortality in Asian patients (hazard ratio: 1.50; 95% CI: 1.21 to 1.87) than in white patients (hazard ratio: 1.29; 95% CI: 1.22 to 1.36; P-interaction = 0.045). CONCLUSIONS Diabetes was 3-fold more common in Southeast Asian compared to white patients with HF, despite younger age and less obesity, and more strongly associated with poor outcomes in Asian patients than white patients. These results underscore the importance of ethnicity-tailored aggressive strategies to prevent diabetes and its complications. (C) 2017 by the American College of Cardiology Foundation.

Methods We compared the association of QRSd with ejection fraction (EF) and outcomes between 839 Singaporean Asian and 11221 Swedish white patients with HF having preserved EF (HFPEF)and HF having reduced EF (HFREF) were followed in prospective population-based HF studies. Results Compared with whites, Asian patients with HF were younger (62 vs 74years, pamp;lt;0.001), had smaller body size (height 163 vs 171cm, weight 70 vs 80kg, both pamp;lt;0.001) and had more severely impaired EF (EF was amp;lt;30% in 47% of Asians vs 28% of whites). Overall, unadjusted QRSd was shorter in Asians than whites (101 vs 104ms, pamp;lt;0.001). Lower EF was associated with longer QRSd (pamp;lt;0.001), with a steeper association among Asians than whites (p(interaction)amp;lt;0.001), independent of age, sex and clinical covariates (including body size). Excluding patients with left bundle branch block (LBBB) and adjusting for clinical covariates, QRSd was similar in Asians and whites with HFPEF, but longer in Asians compared with whites with HFREF (p=0.001). Longer QRSd was associated with increased risk of HF hospitalisation or death (absolute 2-year event rate for 120ms was 40% and for amp;gt;120ms it was 52%; HR for 10ms increase of QRSd was 1.04 (1.03 to 1.06), pamp;lt;0.001), with no interaction by ethnicity. Conclusion We found ethnic differences in the association between EF and QRSd among patients with HF. QRS prolongation was similarly associated with increased risk, but the implications for ethnicity-specific QRSd cut-offs in clinical decision-making require further study.
17.	Jaarsma, Tiny, et al. (author) Self-care of heart failure patients: practical management recommendations from the Heart Failure Association of the European Society of Cardiology 2021 In: European Journal of Heart Failure. - : WILEY. - 1388-9842 .- 1879-0844. ; 23:1, s. 157-174 Journal article (peer-reviewed)abstract Self-care is essential in the long-term management of chronic heart failure. Heart failure guidelines stress the importance of patient education on treatment adherence, lifestyle changes, symptom monitoring and adequate response to possible deterioration. Self-care is related to medical and person-centred outcomes in patients with heart failure such as better quality of life as well as lower mortality and readmission rates. Although guidelines give general direction for self-care advice, health care professionals working with patients with heart failure need more specific recommendations. The aim of the management recommendations in this paper is to provide practical advice for health professionals delivering care to patients with heart failure. Recommendations for nutrition, physical activity, medication adherence, psychological status, sleep, leisure and travel, smoking, immunization and preventing infections, symptom monitoring, and symptom management are consistent with information from guidelines, expert consensus documents, recent evidence and expert opinion.

(author) Association between loop diuretic dose changes and outcomes in chronic heart failure : observations from the ESC-EORP Heart Failure Long-Term Registry. 2020 In: European Journal of Heart Failure. - : Wiley. - 1388-9842 .- 1879-0844. ; 22:8, s. 1424-1437 Journal article (peer-reviewed)abstract AIMS: Guidelines recommend down-titration of loop diuretics (LD) once euvolaemia is achieved. In outpatients with heart failure (HF), we investigated LD dose changes in daily cardiology practice, agreement with guideline recommendations, predictors of successful LD down-titration and association between dose changes and outcomes.METHODS AND RESULTS: We included 8130 HF patients from the ESC-EORP Heart Failure Long-Term Registry. Among patients who had dose decreased, successful decrease was defined as the decrease not followed by death, HF hospitalization, New York Heart Association class deterioration, or subsequent increase in LD dose. Mean age was 66 ± 13 years, 71% men, 62% HF with reduced ejection fraction, 19% HF with mid-range ejection fraction, 19% HF with preserved ejection fraction. Median [interquartile range (IQR)] LD dose was 40 (25-80) mg. LD dose was increased in 16%, decreased in 8.3% and unchanged in 76%. Median (IQR) follow-up was 372 (363-419) days. Diuretic dose increase (vs. no change) was associated with HF death [hazard ratio (HR) 1.53, 95% confidence interval (CI) 1.12-2.08; P = 0.008] and nominally with cardiovascular death (HR 1.25, 95% CI 0.96-1.63; P = 0.103). Decrease of diuretic dose (vs. no change) was associated with nominally lower HF (HR 0.59, 95% CI 0.33-1.07; P = 0.083) and cardiovascular mortality (HR 0.62, 95% CI 0.38-1.00; P = 0.052). Among patients who had LD dose decreased, systolic blood pressure [odds ratio (OR) 1.11 per 10 mmHg increase, 95% CI 1.01-1.22; P = 0.032], and absence of (i) sleep apnoea (OR 0.24, 95% CI 0.09-0.69; P = 0.008), (ii) peripheral congestion (OR 0.48, 95% CI 0.29-0.80; P = 0.005), and (iii) moderate/severe mitral regurgitation (OR 0.57, 95% CI 0.37-0.87; P = 0.008) were independently associated with successful decrease.CONCLUSION: Diuretic dose was unchanged in 76% and decreased in 8.3% of outpatients with chronic HF. LD dose increase was associated with worse outcomes, while the LD dose decrease group showed a trend for better outcomes compared with the no-change group. Higher systolic blood pressure, and absence of (i) sleep apnoea, (ii) peripheral congestion, and (iii) moderate/severe mitral regurgitation were independently associated with successful dose decrease.

(author) Fruit and vegetable consumption and lung cancer risk: Updated information from the European Prospective Investigation into Cancer and Nutrition (EPIC) 2007 In: International Journal of Cancer. - : Wiley. - 0020-7136 .- 1097-0215. ; 121:5, s. 1103-1114 Journal article (peer-reviewed)abstract The association of fruit and vegetable consumption and lung cancer incidence was evaluated using the most recent data from the European Prospective Investigation into Cancer and Nutrition (EPIC), applying a refined statistical approach (calibration) to account for measurement error potentially introduced by using food frequency questionnaire data. Between 1992 and 2000, detailed information on diet and life-style of 478,590 individuals participating in EPIC was collected. During a median follow-up of 6.4 years, 1,126 lung cancer cases were observed. Multivariate Cox proportional hazard models were applied for statistical evaluation. In the whole study population, fruit consumption was significantly inversely associated with lung cancer risk while no association was found for vegetable consumption. In current smokers, however, lung cancer risk significantly decreased with higher vegetable consumption; this association became more pronounced after calibration, the hazard ratio (HR) being 0.78 (95% CI 0.620.98) per 100 g increase in daily vegetable consumption. In comparison, the HR per 100 g fruit was 0.92 (0.85-0.99) in the entire cohort and 0.90 (0.81-0.99) in smokers. Exclusion of cases diagnosed during the first 2 years of follow-up strengthened these associations, the HR being 0.71 (0.55-0.94) for vegetables (smokers) and 0.86 (0.78-0.95) for fruit (entire cohort). Cancer incidence decreased with higher consumption of apples and pears (entire cohort) as well as root vegetables (smokers). In addition to an overall inverse association with fruit intake, the results of this evaluation add evidence for a significant inverse association of vegetable consumption and lung cancer incidence in smokers.

(author) Heart failure in Tanzania and Sweden: Comparative characterization and prognosis in the Tanzania Heart Failure (TaHeF) study and the Swedish Heart Failure Registry (SwedeHF) 2016 In: International Journal of Cardiology. - : ELSEVIER IRELAND LTD. - 0167-5273 .- 1874-1754. ; 220, s. 750-758 Journal article (peer-reviewed)abstract Background: Heart failure (HF) in developing countries is poorly described. We compare characteristics and prognosis of HF in Tanzania vs. Sweden. Methods: A prospective cohort study was conducted from the Tanzania HF study (TaHeF) and the Swedish HF Registry (SwedeHF). Patients were compared overall (n 427 vs. 51,060) and after matching 1: 3 by gender and age +/- 5 years (n 411 vs. 1232). The association between cohort and all-cause mortality was assessed with multivariable Cox regression. Results: In the unmatched cohorts, TaHeF (as compared to SwedeHF) patients were younger (median age [inter-quartile range] 55 [40-68] vs. 77 [64-84] years, p amp;lt; 0.001) and more commonly women (51% vs. 40%, p amp;lt; 0.001). The three-year survival was 61% in both cohorts. In the matched cohorts, TaHeF patients had more hypertension (47% vs. 37%, p amp;lt; 0.001), more anemia (57% vs. 9%), more preserved EF, more advanced HF, longer duration of HF, and less use of beta-blockers. Crude mortality was worse in TaHeF (HR 2.25 [95% CI 1.78-2.85], p amp;lt; 0.001), with three-year survival 61% vs. 83%. However, covariate-adjusted risk was similar (HR 1.07, 95% CI 0.69-1.66; p = 0.760). In both cohorts, preserved EF was associated with higher mortality in crude but not adjusted analysis. Conclusions: Compared to in Sweden, HF patients in Tanzania were younger and more commonly female, and after age and gender matching, had more frequent hypertension and anemia, more severe HF despite higher EF, and worse crude but similar adjusted prognosis.

(author) Artificial intelligence-based versus manual assessment of prostate cancer in the prostate gland: a method comparison study 2019 In: Clinical Physiology and Functional Imaging. - : Wiley. - 1475-0961 .- 1475-097X. ; 39:6, s. 399-406 Journal article (peer-reviewed)abstract Aim : To test the feasibility of a fully automated artificial intelligence-based method providing PET measures of prostate cancer (PCa). Methods : A convolutional neural network (CNN) was trained for automated measurements in 18F-choline (FCH) PET/CT scans obtained prior to radical prostatectomy (RP) in 45 patients with newly diagnosed PCa. Automated values were obtained for prostate volume, maximal standardized uptake value (SUVmax), mean standardized uptake value of voxels considered abnormal (SUVmean) and volume of abnormal voxels (Volabn). The product SUVmean × Volabn was calculated to reflect total lesion uptake (TLU). Corresponding manual measurements were performed. CNN-estimated data were compared with the weighted surgically removed tissue specimens and manually derived data and related to clinical parameters assuming that 1 g ≈ 1 ml of tissue. Results : The mean (range) weight of the prostate specimens was 44 g (20–109), while CNN-estimated volume was 62 ml (31–108) with a mean difference of 13·5 g or ml (95% CI: 9·78–17·32). The two measures were significantly correlated (r = 0·77, P<0·001). Mean differences (95% CI) between CNN-based and manually derived PET measures of SUVmax, SUVmean, Volabn (ml) and TLU were 0·37 (−0·01 to 0·75), −0·08 (−0·30 to 0·14), 1·40 (−2·26 to 5·06) and 9·61 (−3·95 to 23·17), respectively. PET findings Volabn and TLU correlated with PSA (P<0·05), but not with Gleason score or stage. Conclusion : Automated CNN segmentation provided in seconds volume and simple PET measures similar to manually derived ones. Further studies on automated CNN segmentation with newer tracers such as radiolabelled prostate-specific membrane antigen are warranted.

Heart and Circulatory Physiology. - : American Physiological Society. - 0363-6135 .- 1522-1539. ; 301:6, s. H2433-H2441 Journal article (peer-reviewed)abstract Sahlen A, Abdula G, Norman M, Manouras A, Brodin LA, Lund LH, Shahgaldi K, Winter R. Arterial vasodilatory and ventricular diastolic reserves determine the stroke volume response to exercise in elderly female hypertensive patients. Am J Physiol Heart Circ Physiol 301: H2433-H2441, 2011. First published September 16, 2011; doi:10.1152/ajpheart.00555.2011.-Elderly female hypertensives with arterial stiffening constitute a majority of patients with heart failure with preserved ejection fraction (HFpEF), a condition characterized by inability to increase cardiac stroke volume (SV) with physical exercise. As SV is determined by the interaction between the left ventricle (LV) and its load, we wished to study the role of arterial hemodynamics for exertional SV reserve in patients at high risk of HFpEF. Twenty-one elderly (67 +/- 9 yr) female hypertensive patients were studied at rest and during supine bicycle stress using echocardiography including pulsed-wave Doppler to record flow in the LV outflow tract and arterial tonometry for central arterial pressure waveforms. Arterial compliance was estimated based on an exponential relationship between pressure and volume. The ratio of aortic pressure-to-flow in early systole was used to derive characteristic impedance, which was subsequently subtracted from total resistance (mean arterial pressure/cardiac output) to yield systemic vascular resistance (SVR). It was found that patients with depressed SV reserve (NoRes; reserve <15%; n = 10) showed decreased arterial compliance during exercise, while patients with SV reserve >= 15% (Res; n = 11) showed increased compliance. Exercise produced parallel increases in LV end-diastolic volume and arterial volume in Res patients while NoRes patients exhibited a lesser decrease in SVR and a drop in effective arterial volume. Poor SV reserve in elderly female hypertensives is due to simultaneous failure of LV preload and arterial vasodilatory reserves. Abnormal arterial function contributes to a high risk of HFpEF in these patients.

Sacubitril/valsartan has been compared with a renin-angiotensin- system (RAS) inhibitor alone in two similarly designed clinical trials of patients with reduced and preserved LVEF, permitting examination of its effects across the full spectrum of LVEF. Methods: We combined data from PARADIGM-HF (LVEF eligibility≤40%; n=8,399) and PARAGON-HF (LVEF eligibility≥45%; n=4,796) in a prespecified pooled analysis. We divided randomized patients into LVEF categories:≤22.5% (n=1269), >22.5% to 32.5% (n=3987), >32.5% to 42.5% (n=3143), > 42.5% to 52.5% (n=1427), > 52.5% to 62.5% (n=2166), >62.5% (n=1202). We assessed time to first cardiovascular death and HF hospitalization, its components, and total heart failure hospitlizations, all-cause mortality and non-cardiovascular mortality. Incidence rates and treatment effects were examined across categories of LVEF. Results: Among 13,195 randomized patients, we observed lower rates of cardiovascular death and HF hospitalization, but similar rates of non-cardiovascular death, among patients in the highest vs. lowest groups. Overall sacubitril/valsartan was superior to RAS inhibition for first cardiovascular death or heart failure hospitalization (HR 0.84, 95% CI 0.78, 0.90), cardiovascular death (HR 0.84, 95% CI 0.76, 0.92), heart failure hospitalization (HR 0.84, 95% CI 0.77, 0.91), and all-cause mortality (HR 0.88, 95% CI 0.81, 0.96). The effect of sacubitril/valsartan was modified by LVEF (treatment-by-continuous LVEF interaction p=0.02), and benefit appeared to be present for individuals with EF primarily below the normal range, although the treatment benefit for cardiovascular death diminished at a lower ejection fraction. We observed effect modification by LVEF on the efficacy of sacubitril/valsartan in both men and women with respect to composite total HF hospitalizations and cardiovascular death, although women derived benefit to higher ejection fractions. Conclusions:The therapeutic effects of sacubitril/valsartan, compared with a RAS inhibitor alone, vary by LVEF, with treatment benefits, particularly for heart failure hospitalization, that appear to extend to patients with heart failure and mildly reduced ejection fraction. These therapeutic benefits appeared to extend to a higher LVEF range in women compared with men.

In contrast, the role or lifetime exposure to alcohol with regard to risk of SCC is not well established. Historical data oil alcohol use are available in 271,253 participants of the European Prospective Investigation into Cancer and Nutrition (EPIC). During 2,330,381 person years, 392 incident SCC cases (279 men and 113 women) were identified. Cox regression vas applied to model sex-specific associations between lifetime alcohol intake and SCC risk adjusting for potential confounders including smoking. Compared to men who drank 0.1-6.0 g/day alcohol at lifetime, the relative risks (RR) for developing SCC were significantly increased for men who drank 30.1-60.0 g/day (RR 1.65, 95% confidence interval: 1.00-2.71), 60.1-96.0 g/day (RR 2.20, 95%CI 1.23-3.95), and >96.0 g/day, (RR 4.63, 95% CI 2.52-8.48), and for former drinkers (RR 4.14, 95% CI 2.38-7.19). These risk estimates did not considerably change when baseline alcohol intake was analyzed. Compared to women who drank 0.1-6.0 g/day alcohol intake at lifetime, the RR were significantly increased for women who drank >30 g/d (RR 6.05, 95% CI 2.98-12.3). Applying similar categories, the relative risk for baseline alcohol intake was 3.26 (95%CI 1.82-5.87). We observed a stronger association between alcohol intake at lifetime and risk of SCC in women compared to men (p for interaction = 0.045). The strong dose-response relation for lifetime alcohol use underscores that alcohol is an important risk factor of SCC of the upper aero-digestive tract throughout life. (C) 2009 UICC

(author) Machine Learning Methods Improve Prognostication, Identify Clinically Distinct Phenotypes, and Detect Heterogeneity in Response to Therapy in a Large Cohort of Heart Failure Patients 2018 In: Journal of the American Heart Association. - : WILEY. - 2047-9980. ; 7:8 Journal article (peer-reviewed)abstract Background-Whereas heart failure (HF) is a complex clinical syndrome, conventional approaches to its management have treated it as a singular disease, leading to inadequate patient care and inefficient clinical trials. We hypothesized that applying advanced analytics to a large cohort of HF patients would improve prognostication of outcomes, identify distinct patient phenotypes, and detect heterogeneity in treatment response. Methods and Results-The Swedish Heart Failure Registry is a nationwide registry collecting detailed demographic, clinical, laboratory, and medication data and linked to databases with outcome information. We applied random forest modeling to identify predictors of 1-year survival. Cluster analysis was performed and validated using serial bootstrapping. Association between clusters and survival was assessed with Cox proportional hazards modeling and interaction testing was performed to assess for heterogeneity in response to HF pharmacotherapy across propensity-matched clusters. Our study included 44 886 HF patients enrolled in the Swedish Heart Failure Registry between 2000 and 2012. Random forest modeling demonstrated excellent calibration and discrimination for survival (C-statistic=0.83) whereas left ventricular ejection fraction did not (C-statistic=0.52): there were no meaningful differences per strata of left ventricular ejection fraction (1-year survival: 80%, 81%, 83%, and 84%). Cluster analysis using the 8 highest predictive variables identified 4 clinically relevant subgroups of HF with marked differences in 1-year survival. There were significant interactions between propensity-matched clusters (across age, sex, and left ventricular ejection fraction and the following medications: diuretics, angiotensin-converting enzyme inhibitors, )i-blockers, and nitrates, Pamp;lt;0.001, all). Conclusions-Machine learning algorithms accurately predicted outcomes in a large data set of HF patients. Cluster analysis identified 4 distinct phenotypes that differed significantly in outcomes and in response to therapeutics. Use of these novel analytic approaches has the potential to enhance effectiveness of current therapies and transform future HF clinical trials.

A review from the Study Group on Biomarkers of the Heart Failure Association of the European Society of Cardiology 2022 In: European Journal of Heart Failure. - : WILEY. - 1388-9842 .- 1879-0844. ; 24:6, s. 944-958 Research review (peer-reviewed)abstract In patients with heart failure, the beneficial effects of drug and device therapies counteract to some extent ongoing cardiac damage. According to the net balance between these two factors, cardiac geometry and function may improve (reverse remodelling, RR) and even completely normalize (remission), or vice versa progressively deteriorate (adverse remodelling, AR). RR or remission predict a better prognosis, while AR has been associated with worsening clinical status and outcomes. The remodelling process ultimately involves all cardiac chambers, but has been traditionally evaluated in terms of left ventricular volumes and ejection fraction. This is the second part of a review paper by the Study Group on Biomarkers of the Heart Failure Association of the European Society of Cardiology dedicated to ventricular remodelling. This document examines the proposed criteria to diagnose RR and AR, their prevalence and prognostic value, and the variables predicting remodelling in patients managed according to current guidelines. Much attention will be devoted to RR in patients with heart failure with reduced ejection fraction because most studies on cardiac remodelling focused on this setting.

(author) Association Between Use of Statins and Mortality in Patients With Heart Failure and Ejection Fraction of greater than= 50% 2015 In: Circulation Heart Failure. - : LIPPINCOTT WILLIAMS and WILKINS. - 1941-3289 .- 1941-3297. ; 8:5, s. 862-870 Journal article (peer-reviewed)abstract Background The pathophysiology of heart failure with preserved ejection fraction is poorly understood, but may involve a systemic proinflammatory state. Therefore, statins might improve outcomes in patients with heart failure with preserved ejection fraction defined as 50%. Methods and Results Of 46 959 unique patients in the prospective Swedish Heart Failure Registry, 9140 patients had heart failure and ejection fraction 50% (age 7711 years, 54.0% women), and of these, 3427 (37.5%) were treated with statins. Propensity scores for statin treatment were derived from 40 baseline variables. The association between statin use and primary (all-cause mortality) and secondary (separately, cardiovascular mortality, and combined all-cause mortality or cardiovascular hospitalization) end points was assessed with Cox regressions in a population matched 1:1 based on age and propensity score. In the matched population, 1-year survival was 85.1% for statin-treated versus 80.9% for untreated patients (hazard ratio, 0.80; 95% confidence interval, 0.72-0.89; Pless than0.001). Statins were also associated with reduced cardiovascular death (hazard ratio, 0.86; 95% confidence interval, 0.75-0.98; P=0.026) and composite all-cause mortality or cardiovascular hospitalization (hazard ratio, 0.89; 95% confidence interval, 0.82-0.96; P=0.003). Conclusions In heart failure with ejection fraction 50%, the use of statins was associated with improved outcomes. The mechanisms should be evaluated and the effects tested in a randomized trial.

However, randomized trials may not always be generalizable. The aim was to determine whether statins are associated with improved outcomes in an unselected nationwide population of patients with HF with reduced ejection fraction overall and in relation to ischemic heart disease (IHD). Methods and Results-In the Swedish Heart Failure Registry, 21 864 patients with HF with reduced ejection fraction (age +/- SD, 72+/-12 years; 29% women), of whom 10 345 (47%) were treated with statins, were studied. Propensity scores for statin use were derived from 42 baseline variables. The associations between statin use and outcomes were assessed with Cox regressions in a population matched 1: 1 based on propensity score and age and in the overall population with adjustment for propensity score and age. The primary outcome was all-cause mortality; secondary outcomes were cardiovascular mortality; HF hospitalization; and combined all-cause mortality or cardiovascular hospitalization. Survival at 1 year in the matched population was 83% for statin-treated versus 79% for untreated patients (hazard ratio, 0.81; 95% confidence interval, 0.76-0.86; Pless than0.001). In the unmatched population, 1-year survival was 85% for statin-treated versus 79% for untreated patients, hazard ratio after adjustment for propensity score and age was 0.84 (95% confidence interval, 0.80-0.89; Pless than0.001). No examined baseline variables interacted with statin use except for IHD (P=0.001), with a hazard ratio of 0.76 (95% confidence interval, 0.70-0.82, Pless than0.001) with IHD and 0.95 (95% confidence interval, 0.85-1.07; P=0.430 without IHD. Statin use was also associated with reduced risk for all 3 secondary outcomes. Conclusions-In an unselected nationwide population of patients with HF with reduced ejection fraction, statins were associated with improved outcomes, specifically in the presence of IHD. This contrasts with previous randomized controlled trials. Additional randomized controlled trials with more generalized inclusion or focused on IHD may be warranted.

Materials and Methods: A nationwide population-based retrospective cohort study was performed. All nephrectomies from January 2010 to August 2018 were assessed for postoperative VTE events. Univariable and multivariable analyses were used to evaluate the odds ratio (OR) of clinical variables’ effect on postoperative VTEs, within 4 weeks and 4 months after nephrectomy. Results: In 5213 nephrectomized patients, postoperative VTE incidence was 1% and 2% within 4 weeks and 4 months, respectively. Multivariable analyses revealed that predictors of postoperative VTE within 4 months were: open nephrectomy (OR 2.5, P =.001), history of VTE (OR 13.3, P <.001), length of hospital stay (OR 0.98, P =.02), and lymph node dissection (OR 2.0, P =.04). Limitations included the retrospective and registry-based study design and absence of individual patient data on patient body mass index and length of surgery. CONCLUSION: For nephrectomy, postoperative VTE is rare. Open nephrectomy, history of VTE, length of hospital stay, and lymph node dissection are important risk factors which should be evaluated when tailoring VTE prophylaxis regimens.

Independent participant data for quality of HF care was evaluated against the ESC QIs for HF, and association with mortality estimated using multivariable Cox regression. In total, 43 704 patients from 80 hospitals across Sweden enrolled between 2013-2019 were included, with median follow-up 23.6 months. Of the 16 QIs for HF, 13 could be measured and 5 were inversely associated with all-cause mortality during follow-up. Higher attainment (≥50% vs. <50% attainment) of the composite opportunity-based score (combination of QIs into a single score) for patients with reduced ejection fraction was associated with lower all-cause mortality (adjusted hazard ratio 0.81; 95% confidence interval 0.72-0.91). Attainment of the composite score was less in the outpatient than inpatient setting (adjusted odds ratio 0.85; 95% confidence interval 0.72-0.99). Quality of care varied across hospitals, with assessment of health-related quality of life being the indicator with the widest variation in attainment (interquartile range 61.7%).CONCLUSION: Quality of HF care may be measured using the ESC HF QIs. In Sweden, attainment of HF care evaluated using the QIs demonstrated between and within hospital variation, and many QIs were inversely associated with mortality.

(author) Eligibility for sotagliflozin in a real-world heart failure population based on the SOLOIST-WHF trial enrolment criteria: data from the Swedish heart failure registry 2023 In: European Heart Journal - Cardiovascular Pharmacotherapy. - : OXFORD UNIV PRESS. - 2055-6837 .- 2055-6845. ; 9:4, s. 343-352 Journal article (peer-reviewed)abstract Aims The SOLOIST-WHF trial demonstrated efficacy of sotagliflozin in patients with type 2 diabetes mellitus (T2DM) and recent worsening heart failure (HF) regardless of ejection fraction (EF). Selection criteria in trials may limit their generalizability. Therefore, we aimed to investigate eligibility for sotagliflozin based on the SOLOIST-WHF criteria in a real-world HF population. Methods and results SOLOIST-WHF criteria were applied to patients stabilized after HF hospitalization in the Swedish HF Registry according to (i) literal scenario (all inclusion/exclusion criteria) or (ii) pragmatic scenario (only criteria likely to influence treatment decisions). Of 5453 inpatients with T2DM and recent worsening HF, 51.4% had reduced EF (HFrEF), 19.1% mildly reduced (HFmrEF), and 29.5% preserved EF (HFpEF). Eligibility (literal) was: 27.2% (32.4% in HFrEF, 24.7% in HFmrEF, 19.7% in HFpEF) and eligibility (pragmatic) was 62.8% (69.1%, 60.3%, 53.4%, respectively). In the literal scenario, criteria limiting eligibility were HF duration <3 months, eGFR <30 ml/min/1.73 m(2), age >85 years, acute coronary syndrome <3 months, and insufficiently high N-terminal pro-B-type natriuretic peptide levels. Eligible vs. non-eligible patients had more severe HF, higher cardiovascular (CV) comorbidity burden, higher use of HF treatments, and higher event rates (all-cause death 30.8 vs. 27.2 per 100 patient-years, CV death 19.1 vs. 16.6, and HF hospitalization 36.7 vs. 24.0). Conclusion In this large, real-world HF cohort with T2DM, similar to 1/3 of patients were eligible for sotagliflozin in the literal and similar to 2/3 of patients in the pragmatic scenario. Eligible patients had more severe HF and higher event rates, in particular CV and HF events.

(author) Phenotyping heart failure patients for iron deficiency and use of intravenous iron therapy : data from the Swedish Heart Failure Registry 2021 In: European Journal of Heart Failure. - : Wiley. - 1388-9842 .- 1879-0844. ; 23:11, s. 1844-1854 Journal article (peer-reviewed)abstract Aims Iron deficiency (ID) is associated with poor prognosis regardless of anaemia. Intravenous iron improves quality of life and outcomes in patients with ID and heart failure (HF) with reduced ejection fraction (HFrEF). In the Swedish HF registry, we assessed (i) frequency and predictors of ID testing; (ii) prevalence and outcomes of ID with/without anaemia; (iii) use of ferric carboxymaltose (FCM) and its predictors in patients with ID. Methods and results We used multivariable logistic regressions to assess patient characteristics independently associated with ID testing/FCM use, and Cox regressions to assess risk of outcomes associated with ID. Of 21 496 patients with HF and any ejection fraction enrolled in 2017-2018, ID testing was performed in 27%. Of these, 49% had ID and more specifically 36% had ID-/anaemia-, 15% ID-/anaemia+, 29% ID+/anaemia-, and 20% ID+/anaemia+ (48%, 39%, 13%, 30% and 18% in HFrEF, respectively). Risk of recurrent all-cause hospitalizations was higher in patients with ID regardless of anaemia. Of 1959 patients with ID, 19% received FCM (24% in HFrEF). Important independent predictors of ID testing and FCM use were anaemia, higher New York Heart Association class, having HFrEF, and referral to HF specialty care. Conclusion In this nationwide HF registry, ID testing occurred in only about a quarter of the patients. Among tested patients, ID was present in one half, but only one in five patients received FCM indicating low adherence to current guidelines on screening and treatment.

(author) Use of sodium-glucose co-transporter 2 inhibitors in patients with heart failure and type 2 diabetes mellitus : data from the Swedish Heart Failure Registry 2021 In: European Journal of Heart Failure. - : Wiley. - 1388-9842 .- 1879-0844. ; 23:6, s. 1012-1022 Journal article (peer-reviewed)abstract Aims Use of sodium-glucose co-transporter 2 inhibitors (SGLT2i) in real-world heart failure (HF) is poorly characterised. In contemporary patients with HF and type 2 diabetes mellitus (T2DM) we assessed over time SGLT2i use, clinical characteristics and outcomes associated with SGLT2i use. Methods and results Type 2 diabetes patients enrolled in the Swedish HF Registry between 2016-2018 were considered. We performed multivariable logistic regression models to assess the independent predictors of SGLT2i use and Cox regression models in a 1:3 propensity score-matched cohort and relevant subgroups to investigate the association between SGLT2i use and outcomes. Of 6805 eligible HF patients with T2DM, 376 (5.5%) received SGLT2i, whose use increased over time with 12% of patients on treatment at the end of 2018. Independent predictors of SGLT2i use were younger age, HF specialty care, ischaemic heart disease, preserved kidney function, and absence of anaemia. Over a median follow-up of 256 days, SGLT2i use was associated with a 30% lower risk of cardiovascular (CV) death/first HF hospitalisation (hazard ratio 0.70, 95% confidence interval 0.52-0.95), which was consistent regardless of ejection fraction, background metformin treatment and kidney function. SGLT2i use was also associated with a lower risk of all-cause and CV death, HF and CV hospitalisation, and CV death/myocardial infarction/stroke. Conclusion In a contemporary HF cohort with T2DM, SGLT2i use increased over time, was more common with specialist care, younger age, ischaemic heart disease, and preserved renal function, and was associated with lower mortality and morbidity.

(author) Time-dependent prognostic effects of recipient and donor age in adult heart transplantation 2019 In: Journal of Heart and Lung Transplantation. - : Elsevier BV. - 1053-2498. ; 38:2, s. 174-183 Journal article (peer-reviewed)abstract BACKGROUND: Recipient age and donor age are well-known prognostic factors in adult heart transplantation. However, the association between donor age and recipient age and their interaction and short- and long-term mortality is unknown. METHODS: We studied 64,354 heart transplants to adult recipients between 1988 and 2013 in the ISHLT Registry. Donor age and recipient age were analyzed as continuous and categorical variables and restricted cubic spline functions to assess non-linear associations and interactions. The end-point was all-cause mortality. RESULTS: In the multivariable analysis, the odds ratio for 30-day mortality per 10-year increase in recipient age was 1.05 (95% confidence interval [CI] 1.01 to 1.08, p = 0.009) compared with 1.19 (95% CI 1.15 to 1.22, p < 0.001) for donor age. In the first year, the hazard ratio for mortality was 1.05 (95% CI 1.02 to 1.07, p < 0.001) for a 10-year increase in recipient age and 1.16 (1.14 to 1.18, p < 0.001) for donor age. In Years 1 to 3, 3 to 5, and 5 to 10 post-transplant, the hazard ratio was 0.89 (95% CI 0.86 to 0.92, p < 0.001), 0.98 (95% CI 0.94 to 1.02, p = 0.266), and 1.14 (95% CI 1.11 to 1.17, p < 0.001) for recipient age, and 1.12 (95% CI 1.08 to 1.14, p < 0.001), 1.07 (95% CI 1.03 to 1.10, p < 0.001), and 1.07 (95% CI 1.05 to 1.10, p < 0.001) for donor age, respectively. There was no interaction of recipient age and donor age with survival at any follow-up time-point. CONCLUSIONS: At 30 days, both higher donor age and recipient age were associated with higher mortality. At 1 to 10 years, older donor age was associated with higher mortality at all follow-up time-points, but the hazard was greater in the short term, and recipient age was associated only with longer term mortality. The risk from donor age appears equal across recipient age groups.

(author) Survival Probability and Survival Benefit Associated With Primary Prevention Implantable Cardioverter-Defibrillator Generator Changes 2022 In: Journal of the American Heart Association. - : Wiley. - 2047-9980. ; 11:13 Journal article (peer-reviewed)abstract Background As patients derive variable benefit from generator changes (GCs) of implantable cardioverter-defibrillators (ICDs) with an original primary prevention (PP) indication, better predictors of outcomes are needed. Methods and Results In the National Cardiovascular Data Registry ICD Registry, patients undergoing GCs of initial non-cardiac resynchronization therapy PP ICDs in 2012 to 2016, predictors of post-GC survival and survival benefit versus control heart failure patients without ICDs were assessed. These included predicted annual mortality based on the Seattle Heart Failure Model, left ventricular ejection fraction (LVEF) >35%, and the probability that a patients death would be arrhythmic (proportional risk of arrhythmic death [PRAD]). In 40 933 patients undergoing GCs of initial noncardiac resynchronization therapy PP ICDs (age 67.7 +/- 12.0 years, 24.5% women, 34.1% with LVEF >35%), Seattle Heart Failure Model-predicted annual mortality had the greatest effect size for decreased post-GC survival (P<0.0001). Patients undergoing GCs of initial noncardiac resynchronization therapy PP ICDs with LVEF >35% had a lower Seattle Heart Failure Model-adjusted survival versus 23 472 control heart failure patients without ICDs (model interaction hazard ratio, 1.21 [95% CI, 1.11-1.31]). In patients undergoing GCs of initial noncardiac resynchonization therapy PP ICDs with LVEF <= 35%, the model indicated worse survival versus controls in the 21% of patients with a PRAD 65%. The association of the PRAD with survival benefit or harm was similar in patients with or without pre-GC ICD therapies. Conclusions Patients who received replacement of an ICD originally implanted for primary prevention and had at the time of GC either LVEF >35% alone or both LVEF <= 35% and PRAD <43% had worse survival versus controls without ICDs.

The relationship between electrical conductance and degree of reduction was determined by oxidative and reductive titrations of V(IV) and V(V) species leached from catalyst samples which had been reduced to different levels. In situ monitoring of the steady-state V(IV) ion concentration by electrical conductance during reduction with NH3 + NO in the concentration range 0-600 ppm for each reactant in a 2 vol % O2/Ar carrier gas was performed. In a large excess of NH3, the V(IV) ion concentration increased sharply with even small additions of NO. In a large excess of NO, the NH3 + NO mixture exhibited first an oxidizing character, and the V(IV) ion concentration increased when P(NH3) > 1/6P(NO). The reaction order with respect to the NO concentration, determined from both the NO conversion and the initial rate of catalyst reduction in excess NH3, was found to be less than unity. Determination of the stoichiometry of the reaction with respect to O2 indicated that the gas-phase O2 concentration required to balance the reducing character of NH3 + NO mixtures on the surface was significantly higher than predicted by the balanced equation describing the reaction. ESR measurements on the catalyst detected V(IV) ions as vanadyl groups having two different coordination spheres. Reduction of the catalyst with NH3 + NO caused an increase in the V(IV) signal and a decrease of the hyperfine structure.

(author) Accuracy and diagnostic performance of doppler echocardiography to estimate mean pulmonary artery pressure in heart failure 2021 In: Echocardiography. - : John Wiley & Sons. - 0742-2822 .- 1540-8175. ; 38:9, s. 1624-1631 Journal article (peer-reviewed)abstract Background: Multiple echocardiographic algorithms have been proposed to estimate mean pulmonary artery pressure (PAPM) and assess pulmonary hypertension (PH) likelihood. We assessed the accuracy of four echocardiographic approaches to estimate PAPM in heart failure (HF) patients undergoing near-simultaneous right heart catheterization (RHC), and compared diagnostic performance to identify PH with recommendation-advised tricuspid regurgitation peak velocity (TRVmax).Methods: We employed four validated echocardiographic algorithms incorporating tricuspid regurgitation peak or mean gradient, pulmonary regurgitation peak gradient, and right ventricular outflow tract acceleration time to estimate PAPM. Echocardiographic estimates of right atrial pressure were incorporated in all algorithms but one. Association and agreement with invasive PAPM were assessed. Diagnostic performance of all algorithms to identify PH was evaluated and compared with the recommended TRVmax cut-off.Results: In 112 HF patients, all echocardiographic algorithms demonstrated reasonable association (r =.41–.65; p < 0.001) and good agreement with invasive PAPM, with relatively lower mean bias and higher precision observed in algorithms that incorporated tricuspid regurgitation peak or mean gradient. All methods demonstrated strong ability to identify PH (AUC =.70–.80; p < 0.001) but did not outperform TRVmax (AUC =.84; p < 0.001). Echocardiographic estimates of right atrial pressure were falsely elevated in 30% of patients.Conclusions: Echocardiographic estimates demonstrate reasonable association with invasive PAPM and strong ability to identify PH in HF. However, none of the algorithms outperformed recommendation-advised TRVmax. The incremental value of echocardiographic estimates of right atrial pressure may need to be re-evaluated.

(author) Continuous-flow LVADs in the Nordic countries : complications and mortality and its predictors 2019 In: Scandinavian Cardiovascular Journal. - : Informa UK Limited. - 1401-7431 .- 1651-2006. ; 53:1, s. 14-20 Journal article (peer-reviewed)abstract Objectives: The purpose of this study was to assess complications and mortality and its predictors, with continuous-flow left ventricular assist devices (CF-LVADs) in the Nordic Countries.Design: This was a retrospective, international, multicenter cohort study.Results: Between 1993 and 2013, 442 surgically implanted long-term mechanical assist devices were used among 8 centers in the Nordic countries. Of those, 238 were CF-LVADs (HVAD or HeartMate II) implanted in patients >18 years with complete data. Postoperative complications and survival were compared and Cox proportion hazard regression analysis was used to identify predictors of mortality. The overall Kaplan-Meier survival rate was 75% at 1 year, 69% at 2 years and 63% at 3 years. A planned strategy of destination therapy had poorer survival compared to a strategy of bridge to transplantation or decision (2-year survival of 41% vs. 76%, p < .001). The most common complications were non-driveline infections (excluding sepsis) (44%), driveline infection (27%), need for continuous renal replacement therapy (25%) and right heart failure (24%). In a multivariate model age and left ventricular diastolic dimension was left as independent risk factors for mortality with a hazard ratio of 1.35 (95% confidence interval (CI) [1.01-1.80], p = .046) per 10 years and 0.88 (95% CI [0.72-0.99], p = .044) per 5 mm, respectively.Conclusion: Outcome with CF LVAD in the Nordic countries was comparable to other cohorts. Higher age and destination therapy require particularly stringent selection.

(author) New York Heart Association functional class, QRS duration, and survival in heart failure with reduced ejection fraction : implications for cardiac resychronization therapy. 2017 In: European Journal of Heart Failure. - : Wiley-Blackwell. - 1388-9842 .- 1879-0844. ; 19:3, s. 366-376 Journal article (peer-reviewed)abstract AIMS: Symptom severity assessed by NYHA functional class and QRS duration are essential criteria for selection of heart failure (HF) patients for CRT. This study assessed the relationship between NYHA class, QRS duration, and survival in a nationwide HF registry.METHODS AND RESULTS: We studied 13 423 patients with HF in NYHA class II-IV and LVEF <40% in the Swedish Heart Failure Registry. Survival was followed via the Swedish Population Registry. Of 12 534 patients without CRT (age 71 ± 12 years, 29% women), 51% and 49% were in NYHA class II and III-IV, respectively. Patients in NYHA class II compared with class III-IV were younger (69 vs. 73 years), and had a better systolic function (49% vs. 58% with LVEF <30%), P <0.001 for all, and a favourable co-morbidity profile. QRS duration was 116 ± 29 ms in NYHA class II and 119 ± 29 ms in NYHA class III-IV with QRS ≥120 ms found in 37% vs. 44%, and an LBBB in 23% vs. 28% (P < 0.001 for all). Upon multivariable Cox regression adjusting for 40 clinically relevant variables, mortality risk was higher in NYHA class III-IV vs. class II, with a hazard ratio (HR) of 1.31, 95% confidence interval (CI) 1.23-1.40. Mortality was also higher with QRS prolongation ≥120 ms vs. narrow QRS. The HR in NYHA class II patients with non-LBBB was 1.19 (95% CI 1.05 - 1.36) and in those with LBBB it was 1.16 (95% CI 1.03-1.41). The corresponding HRs in NYHA class III-IV were 1.33 (95% CI 1.21-1.47) and 1.12 (95% CI 1.02-1.22). There was no significant interaction between the effects of NYHA class and QRS duration or morphology on mortality. Applying different scenarios to estimate guideline adherence, fewer patients with NYHA class II (range 14.4-42.6%) compared with NYHA class III-IV (18.0-45.4%) had received a CRT device when indicated.CONCLUSIONS: In HF with reduced LVEF, QRS prolongation is common and independently linked to worse survival. The increase in mortality risk associated with QRS prolongation of both LBBB and non-LBBB morphology is similar in NYHA class II and III-IV.
42.	Canzian, Federico, et al. (author) Comprehensive analysis of common genetic variation in 61 genes related to steroid hormone and insulin-like growth factor-I metabolism and breast cancer risk in the NCI breast and prostate cancer cohort consortium. 2010 In: Human Molecular Genetics. - : Oxford University Press (OUP). - 0964-6906 .- 1460-2083. ; 19:19, s. 3873-84 Journal article (peer-reviewed)abstract There is extensive evidence that increases in blood and tissue concentrations of steroid hormones and of insulin-like growth factor I (IGF-I) are associated with breast cancer risk. However, studies of common variation in genes involved in steroid hormone and IGF-I metabolism have yet to provide convincing evidence that such variants predict breast cancer risk. The Breast and Prostate Cancer Cohort Consortium (BPC3) is a collaboration of large US and European cohorts. We genotyped 1416 tagging single nucleotide polymorphisms (SNPs) in 37 steroid hormone metabolism genes and 24 IGF-I pathway genes in 6292 cases of breast cancer and 8135 controls, mostly Caucasian, postmenopausal women from the BPC3. We also imputed 3921 additional SNPs in the regions of interest. None of the SNPs tested was significantly associated with breast cancer risk, after correction for multiple comparisons. The results remained null when cases and controls were stratified by age at diagnosis/recruitment, advanced or nonadvanced disease, body mass index, with or without in situ cases; or restricted to Caucasians. Among 770 estrogen receptor-negative cases, an SNP located 3' of growth hormone receptor (GHR) was marginally associated with increased risk after correction for multiple testing (P(trend) = 1.5 × 10(-4)). We found no significant overall associations between breast cancer and common germline variation in 61 genes involved in steroid hormone and IGF-I metabolism in this large, comprehensive study. Although previous studies have shown that variations in these genes can influence endogenous hormone levels, the magnitude of the effect of single SNPs does not appear to be sufficient to alter breast cancer risk.

(author) Use of and association between heart failure pharmacological treatments and outcomes in obese versus non-obese patients with heart failure with reduced ejection fraction: data from the Swedish Heart Failure Registry 2023 In: European Journal of Heart Failure. - : WILEY. - 1388-9842 .- 1879-0844. ; 25:5, s. 698-710 Journal article (peer-reviewed)abstract Aims To investigate the use of guideline-directed medical therapies (GDMT) and associated outcomes in obese (body mass index >= 30 kg/m(2)) versus non-obese patients with heart failure (HF) with reduced ejection fraction (HFrEF). Methods and results Patients with HFrEF from the Swedish HF Registry were included. Of 16 116 patients, 24% were obese. In obese versus non-obese patients, use of treatments was 91% versus 86% for renin-angiotensin system inhibitors (RASi)/angiotensin receptor-neprilysin inhibitors (ARNi), 94% versus 91% for beta-blockers, 53% versus 43% for mineralocorticoid receptor antagonists. Obesity was shown to be independently associated with more likely use of each treatment, triple combination therapy, and the achievement of target dose by multivariable logistic regressions. Multivariable Cox regressions showed use of RASi/ARNi and beta-blockers being independently associated with lower risk of all-cause/cardiovascular death regardless of obesity, although, when considering competing risks, a lower risk of cardiovascular death with RASi/ARNi in obese versus non-obese patients was observed. RASi/ARNi were associated with lower risk of HF hospitalization in obese but not in non-obese patients, whereas beta-blockers were not associated with the risk of HF hospitalization regardless of obesity. At the competing risk analysis, RASi/ARNi use was associated with higher risk of HF hospitalization regardless of obesity. Conclusion Obese patients were more likely to receive optimal treatments after adjustment for factors affecting tolerability, suggesting that perceived beyond actual tolerance issues limit GDMT implementation. RASi/ARNi and beta-blockers were associated with lower mortality regardless of obesity, with a greater association between RASi/ARNi and lower cardiovascular death in obese versus non-obese patients when considering competing risk.

(author) Cardiovascular Diseases in similar to 30,000 Patients in the Swedish Dementia Registry 2015 In: Journal of Alzheimer's Disease. - 1387-2877 .- 1875-8908. ; 48:4, s. 949-958 Journal article (peer-reviewed)abstract Background: Cardiovascular diseases are leading causes of death and patients with dementia are often affected by them. Objective: Investigate associations of cardiovascular diseases with different dementia disorders and determine their impact on mortality. Methods: This study included 29,630 patients from the Swedish Dementia Registry (mean age 79 years, 59% women) diagnosed with Alzheimer's disease (AD), mixed dementia, vascular dementia, dementia with Lewy bodies (DLB), Parkinson's disease dementia (PDD), frontotemporal dementia (FTD), or unspecified dementia. Records of cardiovascular diseases come from the Swedish National Patient Register. Multinomial logistic regression and cox proportional hazard models were applied. Results: Compared to AD, we found a higher burden of all cardiovascular diseases in mixed and vascular dementia. Cerebrovascular diseases were more associated with DLB than with AD. Diabetes mellitus was less associated with PDD and DLB than with AD. Ischemic heart disease was less associated with PDD and FTD than AD. All cardiovascular diseases predicted death in patients with AD, mixed, and vascular dementia. Only ischemic heart disease significantly predicted death in DLB patients (HR = 1.72; 95% CI = 1.16-2.55). In PDD patients, heart failure and diabetes mellitus were associated with a higher risk of death (HR = 3.06; 95% CI = 1.74-5.41 and HR = 3.44; 95% CI = 1.31-9.03). In FTD patients, ischemic heart disease and atrial fibrillation or flutter significantly predicted death (HR = 2.11; 95% CI = 1.08-4.14 and HR= 3.15; 95% CI = 1.60-6.22, respectively). Conclusion: Our study highlights differences in the occurrence and prognostic significance of cardiovascular diseases in several dementia disorders. This has implications for the care and treatment of the different dementia disorders.
45.	Cermakova, Pavla, et al. (author) Heart failure and dementia : survival in relation to types of heart failure and different dementia disorders 2015 In: European Journal of Heart Failure. - : Wiley. - 1388-9842 .- 1879-0844. ; 17:6, s. 612-619 Journal article (peer-reviewed)abstract AimsHeart failure (HF) and dementia frequently coexist, but little is known about their types, relationships to each other and prognosis. The aims were to (i) describe patients with HF and dementia, assess (ii) the proportion of specific dementia disorders in types of HF based on ejection fraction and (iii) the prognostic role of types of HF and dementia disorders. Methods and resultsThe Swedish Heart Failure Registry (RiksSvikt) and The Swedish Dementia Registry (SveDem) were record-linked. Associations between dementia disorders and HF types were assessed with multinomial logistic regression and survival was investigated with Kaplan-Meier analysis and multivariable Cox regression. We studied 775 patients found in both registries (55% men, mean age 82years). Ejection fraction was preserved in 38% of patients, reduced in 34%, and missing in 28%. The proportions of dementia disorders were similar across HF types. Vascular dementia was the most common dementia disorder (36%), followed by other dementias (28%), mixed dementia (20%), and Alzheimer disease (16%). Over a mean follow-up of 1.5years, 76% of patients survived 1year. We observed no significant differences in survival with regard to HF type (P=0.2) or dementia disorder (P=0.5). After adjustment for baseline covariates, neither HF types nor dementia disorders were independently associated with survival. ConclusionsHeart failure with preserved ejection fraction was the most common HF type and vascular dementia was the most common dementia disorder. The proportions of dementia disorders were similar across HF types. Neither HF types nor specific dementia disorders were associated with survival.

(author) Age-dependent differences in clinical phenotype and prognosis in heart failure with mid-range ejection compared with heart failure with reduced or preserved ejection fraction 2019 In: Clinical Research in Cardiology. - : Springer Science and Business Media LLC. - 1861-0684 .- 1861-0692. ; 108:12, s. 1394-1405 Journal article (peer-reviewed)abstract Background: HFmrEF has been recently proposed as a distinct HF phenotype. How HFmrEF differs from HFrEF and HFpEF according to age remains poorly defined. We aimed to investigate age-dependent differences in heart failure with mid-range (HFmrEF) vs. preserved (HFpEF) and reduced (HFrEF) ejection fraction. Methods and results: 42,987 patients, 23% with HFpEF, 22% with HFmrEF and 55% with HFrEF, enrolled in the Swedish heart failure registry were studied. HFpEF prevalence strongly increased, whereas that of HFrEF strongly decreased with higher age. All cardiac comorbidities and most non-cardiac comorbidities increased with aging, regardless of the HF phenotype. Notably, HFmrEF resembled HFrEF for ischemic heart disease prevalence in all age groups, whereas regarding hypertension it was more similar to HFpEF in age ≥ 80years, to HFrEF in age < 65years and intermediate in age 65–80years. All-cause mortality risk was higher in HFrEF vs. HFmrEF for all age categories, whereas HFmrEF vs. HFpEF reported similar risk in ≥ 80years old patients and lower risk in < 65 and 65–80years old patients. Predictors of mortality were more likely cardiac comorbidities in HFrEF but more likely non-cardiac comorbidities in HFpEF and HFmrEF with < 65years. Differences among HF phenotypes for comorbidities were less pronounced in the other age categories. Conclusion: HFmrEF appeared as an intermediate phenotype between HFpEF and HFrEF, but for some characteristics such as ischemic heart disease more similar to HFrEF. With aging, HFmrEF resembled more HFpEF. Prognosis was similar in HFmrEF vs. HFpEF and better than in HFrEF. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

There is a large spectrum of CS presentations resulting from the interaction between an acute cardiac insult and a patients underlying cardiac and overall medical condition. Phenotyping patients with CS may have clinical impact on management because classification would support initiation of appropriate therapies. CS management should consider appropriate organization of the health care services, and therapies must be given to the appropriately selected patients, in a timely manner, whilst avoiding iatrogenic harm. Although several consensus-driven algorithms have been proposed, CS management remains challenging and substantial investments in research and development have not yielded proof of efficacy and safety for most of the therapies tested, and outcome in this condition remains poor. Future studies should consider the identification of the new pathophysiological targets, and high-quality translational research should facilitate incorporation of more targeted interventions in clinical research protocols, aimed to improve individual patient outcomes. Designing outcome clinical trials in CS remains particularly challenging in this critical and very costly scenario in cardiology, but information from these trials is imperiously needed to better inform the guidelines and clinical practice. The goal of this review is to summarize the current knowledge concerning the definition, epidemiology, underlying causes, pathophysiology and management of CS based on important lessons from clinical trials and registries, with a focus on improving in-hospital management.

However, the optimal potassium range is unknown. We sought to determine the optimal range of potassium in patients with heart failure and reduced ejection fraction (amp;lt; 40%) by exploring the relationship between baseline potassium level and short- and long-term outcomes using the Swedish Heart Failure Registry from 1 January 2006 to 31 December 2012. Methods and results We assessed the association between baseline potassium level and all-cause mortality at 30 days, 12 months, and maximal follow-up, in uni- and multivariable stratified and restricted cubic spline Cox regressions. Of 13 015 patients, 93.3% had potassium 3.5-5.0 mmol/L, 3.7% had potassium amp;lt;3.5 mmol/L, and 3.0% had potassium amp;gt;5.0 mmol/L. Potassium 5.0 mmol/L were more common with lower estimated glomerular filtration rate and heart failure of longer duration and greater severity. The potassium level associated with the lowest hazard risk for mortality at 30 days, 12 months, and maximal follow-up was 4.2 mmol/L, and there was a steep increase in risk with both higher and lower potassium levels. In adjusted strata analyses, lower potassium was independently associated with all-cause mortality at 12 months and maximal follow-up, while higher potassium levels only increased risk at 30 days. Conclusion In this nationwide registry, the relationship between potassium and mortality was U-shaped, with an optimal potassium value of 4.2 mmol/L. After multivariable adjustment, hypokalaemia was associated with increased long-term mortality but hyperkalaemia was associated with increased short-term mortality.
