Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background and aimsHeart failure (HF) is a major cause of serious morbidity and death in the population and one of the leading medical causes of hospitalization among people older than 60 years. The aim of this thesis was to describe how to create and how to analyze a Heart Failure Registry with emphasis on Anemia and Quality of Life. (Paper I) We described the creation of the Swedish Heart Failure Registry (SwedeHF) as an instrument, which may help to optimize the handling of HF patients and show how the registry can be used to improve the management of patients with HF. (Paper II) In order to show how to analyze a HF registry we investigated the prevalence of anemia, its predictors, and its association with mortality and morbidity in a large cohort of unselected patients with HFrEF included in the SwedeHF, and to explore if there are subgroups of HF patients identifying high--‐risk patients in need of treatment. (Paper III) In order to show another way of analyzing a HF registry we assessed the prevalence of, associations with, and prognostic impact of anemia in patients with HFmrEF and HFpEF. (Paper IV) Finally we examined the usefulness of EQ--‐ 5D as a measure of patient--‐reported outcomes among HF patients using different analytical models and data from the SwedeHF, and comparing results about HRQoL for patients with HFpEF and HFrEF.Methods An observational study based on the SwedeHF database, consisting of about 70 variables, was undertaken to describe how a registry is created and can be used (Paper I). One comorbidity (anemia) was applied to different types of HF patients, HFrEF (EF <40%) (II) and HFmrEF (EF 40--‐49% ) or HFpEF (> 50%) (III) analyzing the data with different statistical methods. The usefulness of EQ--‐5D as measure of patient--‐ reported outcomes was studied and the results about HRQoL were compared for patients with HFpEF and HFrEF (IV).ResultsIn the first paper (Paper I) we showed how to create a HF registry and presented some characteristics of the patients included, however not adjusted since this was not the purpose of the study. In the second paper (Paper II) we studied anemia in patients with HFrEF and found that the prevalence of anemia in HFrEF were 34 % and the most important independent predictors were higher age, male gender and renal dysfunction. One--‐year survival was 75 % with anemia vs. 81 % without (p<0,001). In the matched cohort after propensity score the hazard ratio associated with anemia was for all--‐cause death 1.34. Anemia was associated with greater risk with lower age, male gender, EF 30--‐39%, and NYHA--‐class I--‐II. In the third paper (Paper III) we studied anemia in other types of HF patients and found that the prevalence in the overall cohort in patients with EF > 40% was 42 %, in HFmrEF 38 % and in HFpEF (45%). Independent associations with anemia were HFpEF, male sex, higher age, worse New York Heart Association class and renal function, systolic blood pressure <100 mmHg, heart rate ≥70 bpm, diabetes, and absence of atrial fibrillation. One--‐year survival with vs. without anemia was 74% vs. 89% in HFmrEF and 71% vs. 84% in HFpEF (p<0.001 for all). Thus very similar results in paper II and III but in different types of HF patients. In the fourth paper (Paper IV) we studied the usefulness of EQ--‐5D in two groups of patients with HF (HFpEF and HFrEF)) and found that the mean EQ--‐5D index showed small reductions in both groups at follow--‐up. The patients in the HFpEF group reported worsening in all five dimensions, while those in the HFrEF group reported worsening in only three. The Paretian classification showed that 24% of the patients in the HFpEF group and 34% of those in the HFrEF group reported overall improvement while 43% and 39% reported overall worsening. Multiple logistic regressions showed that treatment in a cardiology clinic affected outcome in the HFrEF group but not in the HFpEF group (Paper IV).Conclusions The SwedeHF is a valuable tool for improving the management of patients with HF, since it enables participating centers to focus on their own potential for improving diagnoses and medical treatment, through the online reports (Paper I). Anemia is associated with higher age, male gender and renal dysfunction and increased risk of mortality and morbidity (II, III). The influence of anemia on mortality was significantly greater in younger patients in men and in those with more stable HF (Paper II, III). The usefulness of EQ--‐5D is dependent on the analytical method used. While the index showed minor differences between groups, analyses of specific dimensions showed different patterns of change in the two groups of patients (HFpEF and HFrEF). The Paretian classification identified subgroups that improved or worsened, and can therefore help to identify needs for improvement in health services (Paper IV).

- Background: It remains unclear whether readmissions of patients with heart failure (HF) have decreased over time in an era of improved therapy and management of HF. This study aimed to determine the temporal short- and long-term trends of cause-specific rehospitalization and their risk factors in a Swedish context. Methods: HF patients in the Swedish Heart Failure Registry (SwedeHF) were investigated. Maximum follow-up time was 1 year. Outcomes included the first occurrence of all-cause, cardiovascular (CV) and HF rehospitalizations. Cox proportional hazards models were performed to determine the impact of increasing years on risk for rehospitalization and its known risk factors. Results: Totally, 25,644 index-hospitalized HF patients in SwedeHF from 2004 to 2011 were enrolled in the study. For 8 years, the incidence risk of 1-year all-cause rehospitalization remained unchanged, whereas the incidence risk of CV (P = 0.038) or HF (P = 0.0038) rehospitalization decreased. After adjustment for age and sex, a 3% decrease per every second year was observed for 1-year CV and HF rehospitalizations (P < 0.05). However, time to the first occurring all-cause, CV and HF rehospitalization did not change significantly from 2004 to 2011 (P-values 0.13-0.87). When two study periods (2004-2005 vs. 2010-2011) were compared, the risk factor profile for rehospitalization was found to change. Conclusions: Throughout the 8-year study period, CV- and HF-related rehospitalizations decreased, whereas all-cause rehospitalization remained unchanged, indicating a parallel increase in non-CV rehospitalization in the HF patients.

- BACKGROUND: The sinus node inhibitor ivabradine was approved for patients with heart failure (HF) after the ivabradine and outcomes in chronic HF (SHIFT [Systolic Heart Failure Treatment With the IF Inhibitor Ivabradine Trial]) trial. Our objective was to characterize the proportion of patients with HF eligible for ivabradine and the representativeness of the SHIFT trial enrollees compared with those in the Swedish Heart Failure Registry. METHODS AND RESULTS: We examined 26 404 patients with clinical HF from the Swedish Heart Failure Registry and divided them into SHIFT type (left ventricular ejection fraction <40%, New York Heart Association class II-IV, sinus rhythm, and heart rate >/=70 beats per minute) and non-SHIFT type. Baseline characteristics and medication use were compared and change in eligibility over time was reported at 6 months and 1 year in a subset of patients. Overall, 14.2% (n=3741) of patients were SHIFT type. These patients were more likely to be younger, men, have diabetes mellitus, ischemic heart disease, lower left ventricular ejection fraction, and more recent onset HF (<6 months; all, P<0.001). Although 88.9% of SHIFT type and 88.5% of non-SHIFT type (P=0.421) were receiving selected beta-blockers, only 58.8% and 67.3% (P<0.001) were on >50% of target dose. From those patients who had repeated visits within 6 months (n=5420) and 1 year (n=6840), respectively, 10.2% (n=555) and 10.6% (n=724) of SHIFT-type patients became ineligible, 77.3% (n=4188) and 77.3% (n=5287) remained ineligible, and 4.6% (n=252) and 4.9% (n=335) of non-SHIFT-type patients became eligible for initiation of ivabradine. CONCLUSIONS: From the Swedish Heart Failure Registry, 14.2% of patients with HF were eligible for ivabradine. These patients more commonly were not receiving target beta-blocker dose. Over time, a minority of patients became ineligible and an even smaller minority became eligible.

- Aims To analyse the long-term outcome, risk factor panorama, and treatment pattern in patients with heart failure (HF) with and without type 2 diabetes (T2DM) from a daily healthcare perspective. Methods and results Patients with (n = 8809) and without (n = 27 465) T2DM included in the Swedish Heart Failure Registry (S-HFR) 2003-2011 due to a physician-based HF diagnosis were prospectively followed for long-term mortality (median follow-up time: 1.9 years, range 0-8.7 years). Left ventricular function expressed as EF did not differ between patients with and without T2DM. Survival was significantly shorter in patients with T2DM, who had a median survival time of 3.5 years compared with 4.6 years (P < 0.0001). In subjects with T2DM. unadjusted and adjusted odds ratios (ORs) for mortality were 1.37 [95% confidence interval (CI) 1.30-1.44) and 1.60 (95% CI 1.50-1.71), and T2DM predicted mortality in all age groups. Ischaemic heart disease was an important predictor for mortality (OR 1.68, 95% CI 1.47-1.94), more abundant in patients with T2DM (59% vs. 45%) among whom only 35% had been subjected to coronary angiography and 32% to revascularization. Evidence-based pharmacological HF treatment was somewhat more extensive in patients with T2DM. Conclusion The combination of T2DM and HF seriously compromises long-term prognosis. Ischaemic heart disease was identified as one major contributor; however, underutilization of available diagnostic and therapeutic facilities for ischaemic heart disease was obvious and may be an important area for future improvement in patients with T2DM and HF.

- Background Heart failure (HF) is a common and serious complication in type 2 diabetes mellitus (T2DM). The prognosis of ischemic HF and impact of revascularization in such patients have not been investigated fully in a patient population representing everyday practice. Objectives This study examined the impact of ischemic versus nonischemic HF and previous revascularization on long-term prognosis in an unselected population of patients with and without T2DM. Methods Patients stratified by diabetes status and ischemic or nonischemic HF and history of revascularization in the Swedish Heart Failure Registry (SwedeHF) from 2003 to 2011 were followed up for mortality predictors and longevity. A propensity score analysis was applied to evaluate the impact of previous revascularization. Results Among 35,163 HF patients, those with T2DM were younger, and 90% had 1 or more associated comorbidities. Ischemic heart disease (IHD) occurred in 62% of patients with T2DM and 47% of those without T2DM, of whom 53% and 48%, respectively, had previously undergone revascularization. T2DM predicted mortality regardless of the presence of IHD, with adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of 1.40 (1.33 to 1.46) and 1.30 (1.22 to 1.39) in those with and without IHD, respectively. Patients with both T2DM and IHD had the highest mortality, which was further accentuated by the absence of previous revascularization (adjusted HR: 0.82 in favor of such treatment; 95% CI: 0.75 to 0.91). Propensity score adjustment did not change these results (HR: 0.87; 95% CI: 0.78 to 0.96). Revascularization did not abolish the impact of T2DM, which predicted mortality in those with (HR: 1.36; 95% CI: 1.24 to 1.48) and without (HR: 1.45; 95% CI: 1.33 to 1.56) a history of revascularization. Conclusions Ninety percent of HF patients with T2DM have preventable comorbidities. IHD in patients with T2DM had an especially negative influence on mortality, an impact that was beneficially influenced by previous revascularization.

- This study aimed to evaluate the outcome and prognostic factors in patients with dilated cardiomyopathy (DCM) and long-standing heart failure (LDCM) vs. recent-onset heart failure (RODCM).We compared 2019 patients with RODCM (duration <6 months, mean age 58.6 years, 70.7% male) with 1714 patients with LDCM (duration ≥6 months, median duration 3.5 years, mean age 62.5 years, 73.7% male) included in the Swedish Heart Failure Registry in the years 2003-16. Outcome measures were all-cause, cardiovascular (CV), and non-CV death and hospitalizations; heart transplantation; and a combined outcome of all-cause death, heart transplantation, or heart failure (HF) hospitalization. Multivariable risk factor analyses were performed for the combined endpoint. All outcomes were more frequent in LDCM than in RODCM. The multivariable-adjusted hazard ratios (HRs) (95% confidence interval) for LDCM vs. RODCM were 1.56 (1.34-1.82), P < 0.0001, for all-cause death over a median follow-up of 4.2 and 5.0 years, respectively; 1.67 (1.36-2.05), P < 0.0001, for CV death; 2.12 (1.14-3.91), P < 0.0001, for heart transplantation; 1.36 (1.21-1.53), P < 0.0001, for HF hospitalization; and 1.37 (1.24-1.52), P < 0.0001, for the combined outcome. A propensity score-matched analysis yielded similar results. CV death was the main cause of mortality in LDCM and was higher in LDCM than in RODCM (P < 0.0001). Almost all co-morbidities were significantly more frequent in LDCM than in RODCM, and the mean number of co-morbidities increased significantly with increased duration of disease, also after age adjustment. Age, New York Heart Association functional class, ejection fraction, and left bundle branch block were prognostically adverse. The only co-morbidity associated with the combined outcome regardless of HF duration was diabetes, in LDCM [HR 1.34 (1.15-1.56), P = 0.0002] and in RODCM [HR 1.29 (1.04-1.59), P = 0.018]. Male sex [HR 1.38 (1.18-1.63), P < 0.0001] and aspirin use [HR 1.33 (1.14-1.55), P = 0.0004] carried increased risk only in RODCM. Heart rate ≥75 b.p.m. [HR 1.20 (1.04-1.37), P = 0.01], atrial fibrillation [HR 1.24 (1.08-1.42), P = 0.0024], musculoskeletal or connective tissue disorder [HR 1.36 (1.13-1.63), P = 0.0014], and diuretic therapy [HR 1.40 (1.17-1.67), P = 0.0002] were prognostically adverse only in LDCM.This nationwide study of patients with DCM demonstrates that longer disease duration is associated with worse prognosis. Co-morbidities are more common in long-standing HF than in recent-onset HF and are associated with worse outcome. With the increased survival seen in the last decades, our results highlight the importance of careful attention to co-morbid conditions in patients with DCM.

- Objective: The aim of this study is to describe patients with heart failure and an ejection fraction (EF) of more than or equal to 40%, managed in both Primary- and Hospital based outpatient clinks separately with their prognosis, comorbidities and risk factors. Further to compare the heart failure medication in the two groups. Design: We used the prospective Swedish Heart Failure Registry to include 9654 out-patients who had HF and EF >= 40%, 1802 patients were registered in primary care and 7852 in hospital care. Descriptive statistical tests were used to analyze base line characteristics in the two groups and multivariate logistic regression analysis to assess mortality rate in the groups separately. Setting: The prospective Swedish Heart Failure Registry. Setting: The prospective Swedish Heart Failure Registry. Subjects: Patients with heart failure and an ejection fraction (EF) of more than or equal to 40%. Main outcome measures: Comorbidities, risk factors and mortality. Results: Mean-age was 77.5 (primary care) and 70.3 years (hospital care) p < 0.0001, 46.7 vs. 36.3% women respectively (p < 0.0001) and EF >= 50% 26.1 vs. 13.4% (p < 0.0001). Co-morbidities were common in both groups (97.2% vs. 92.3%), the primary care group having more atrial fibrillation, hypertension, ischemic heart disease and COPD. According to the multivariate logistic regression analysis smoking, COPD and diabetes were the most important independent risk factors in the primary care group and valvular disease in the hospital care group. All-cause mortality during mean follow-up of almost 4 years was 315% in primary care and 27.8% in hospital care. One year-mortality rates were 7.8%, and 7.0% respectively. Conclusion: Any co-morbidity was noted in 97% of the HF-patients with an EF of more than or equal to 40% managed at primary care based out-patient clinics and these patients had partly other independent risk factors than those patients managed in hospital care based outpatients clinics. Our results indicate that more attention should be payed to manage COPD in the primary care group.

- We investigated the 2 year rate of ischaemic stroke/transient ischaemic attack (IS) in patients with heart failure (HF) who were in sinus rhythm (HF-SR) and aimed to develop a score for stratifying risk of IS in this population.A total of 15 425 patients (mean age 71.5 years, 39% women) with HF-SR enrolled in the Swedish Heart Failure Register were included; 28 815 age-matched and sex-matched controls, without a registered diagnosis of HF, were selected from the Swedish Population Register. The 2 year rate of IS was 3.0% in patients and 1.4% in controls. In the patient group, a risk score including age (1p for 65-74 years; 2p for 75-84 years; 3p for ≥85 years), previous IS (2p), ischaemic heart disease, diabetes, hypertension, kidney dysfunction, and New York Heart Association III/IV class (1p each) was generated. Over a mean follow-up of 20.1 (SD 7.5) months, the cumulative incidences (per 1000 person-years) of IS in patients with score 0 to ≥7 were 2.2, 5.3, 8.9, 13.2, 15.7, 20.4, 26.4, and 33.0, with hazard ratios for score 1 to ≥7 (with 0 as reference): 2.4, 4.1, 6.1, 7.2, 9.4, 12.2, and 15.3. The risk score performed modestly (area under the curve 63.7%; P = 0.4711 for lack of fit with a logistic model; P = 0.7062 with Poisson, scaled by deviance).In terms of absolute risk, only 27.6% of patients had an annual IS incidence of ≤1%. To which extent this would be amenable to anticoagulant treatment remains conjectural. A score compiling age and specific co-morbidities identified HF-SR patients with increased risk of IS with modest discriminative ability.

Tidskriftsartikel (refereegranskat)abstract
- Background: Elderly patients have a relatively high cardiovascular risk due to increased arterial stiffness, elevated blood pressure and decreased amounts of elastin in the arteries. The composition of the media layer in the arterial wall, comprising elastin, collagen, smooth muscle cells, proteoglycans, fibronectin and fibrillin-1, influences its mechanical properties. Mutations in the fibrillin-1 gene leads to increased aortic stiffness, elevated pulse pressure and aortic root dilatation. This study investigates whether there is a sex difference among hypertensive elderly patients regarding blood pressure, arterial stiffness and fibrillin-1 genotypes. Methods: A total of 315 hypertensive subjects (systolic blood pressure > 140 mmHg) were included in this study (155 men and 160 women aged 71-88 years). Aortic pulse wave velocity and augmentation index were determined using SphygmoCor, and brachial blood pressure was measured using an oscillometric technique. Fibrillin-1 was genotyped by polymerase chain reaction and with a capillary electrophoresis system. Results: Females showed a significantly higher peripheral mean arterial pressure (females; 107.20 mmHg, males 101.6 mmHg, p = 0.008), central mean arterial pressure (females; 107.2 mmHg, males 101.6 mmHg p = 0.008), central systolic blood pressure (females; 148.1 mmHg, males 139.2 mmHg, p < 0.001) and central pulse pressure (females; 68.9 mmHg, males 61.6 mmHg, p = 0.035) than males. Females with the Fibrillin-1 2/3 genotype showed a significantly higher augmentation index (FBN1 2/3; 39.9%, FBN1 2/2 35.0%, FBN1 2/4 35.8, p = 0.029) and systolic blood pressure (FBN1 2/3; 174.6 mmHg, FBN1 2/2168.9 mmHg, FBN1 2/4169.9 mmHg, p = 0.025) than females with the 2/2 and 2/4 genotypes. Conclusion: The findings of this study may indicate that hypertensive elderly females, especially elderly females with Fibrillin-1 2/3, have increased systolic blood pressure and arterial stiffness.
