- Background-Diabetes mellitus (DM) is common in patients hospitalized with an acute myocardial infarction (AMI), representing in some cases the first opportunity to recognize and treat DM. We report the incidence of new DM and its recognition among patients with AMI. Methods and Results-Patients in a 24-site US AMI registry (2005-08) had glycosylated hemoglobin assessed at a core laboratory, with results blinded to clinicians and local clinical measurements left to the discretion of the treating providers. Among 2854 AMI patients without known DM on admission, 287 patients (10%) met criteria for previously unknown DM, defined by a core laboratory glycosylated hemoglobin of >= 6.5%. Among these, 186 (65%) were unrecognized by treating clinicians, receiving neither DM education, glucose-lowering medications at discharge, nor documentation of DM in the chart (median glycosylated hemoglobin of unrecognized patients, 6.7%; range, 6.5-12.3%). Six months after discharge, only 5% of those not recognized as having DM during hospitalization had been initiated on glucose-lowering medications versus 66% of those recognized (P< 0.001). Conclusions-Underlying DM that has not been previously diagnosed is common among AMI patients, affecting 1 in 10 patients, yet is recognized by the care team only one third of the time. Given its frequency and therapeutic implications, including but extending beyond the initiation of glucose-lowering treatment, consideration should be given to screening all AMI patients for DM during hospitalization. Inexpensive, ubiquitous, and endorsed as an acceptable screen for DM, glycosylated hemoglobin testing should be considered for this purpose.

- BACKGROUND: Deep neural networks have been used to estimate age from ECGs, the electrocardiographic age (ECG-age), which predicts adverse outcomes. However, this prediction ability has been restricted to clinical settings or relatively short periods. We hypothesized that ECG-age is associated with death and cardiovascular outcomes in the long-standing community-based FHS (Framingham Heart Study).METHODS: We tested the association of ECG-age with chronological age in the FHS cohorts in ECGs from 1986 to 2021. We calculated the gap between chronological and ECG-age (& UDelta;age) and classified individuals as having normal, accelerated, or decelerated aging, if & UDelta;age was within, higher, or lower than the mean absolute error of the model, respectively. We assessed the associations of & UDelta;age, accelerated and decelerated aging with death or cardiovascular outcomes (atrial fibrillation, myocardial infarction, and heart failure) using Cox proportional hazards models adjusted for age, sex, and clinical factors.RESULTS:The study population included 9877 FHS participants (mean age, 55 & PLUSMN;13 years; 54.9% women) with 34 948 ECGs. ECG-age was correlated to chronological age (r=0.81; mean absolute error, 9 & PLUSMN;7 years). After 17 & PLUSMN;8 years of follow-up, every 10-year increase of & UDelta;age was associated with 18% increase in all-cause mortality (hazard ratio [HR], 1.18 [95% CI, 1.12-1.23]), 23% increase in atrial fibrillation risk (HR, 1.23 [95% CI, 1.17-1.29]), 14% increase in myocardial infarction risk (HR, 1.14 [95% CI, 1.05-1.23]), and 40% increase in heart failure risk (HR, 1.40 [95% CI, 1.30-1.52]), in multivariable models. In addition, accelerated aging was associated with a 28% increase in all-cause mortality (HR, 1.28 [95% CI, 1.14-1.45]), whereas decelerated aging was associated with a 16% decrease (HR, 0.84 [95% CI, 0.74-0.95]).CONCLUSIONS:ECG-age was highly correlated with chronological age in FHS. The difference between ECG-age and chronological age was associated with death, myocardial infarction, atrial fibrillation, and heart failure. Given the wide availability and low cost of ECG, ECG-age could be a scalable biomarker of cardiovascular risk.

Echocardiographic and Electrocardiographic Abnormalities Among Elderly Adults With Cardiovascular Disease in Rural South Africa
- 2021
-

Journal article (peer-reviewed)abstract
- BACKGROUND: Sub-Saharan Africa is undergoing an epidemiological transition fueled by the interaction between infectious and cardiovascular diseases. Our cross-sectional study aimed to characterize the spectrum of abnormalities suggesting end-organ damage on ECG and transthoracic echocardiograms (TTE) among older adults with cardiovascular diseases in rural South Africa.METHODS: The prevalence of ECG and TTE abnormalities was estimated; χ2 analyses and multivariable logistic regressions were performed to test their association with sex, hypertension, and other selected comorbidities.RESULTS: Overall, 729 ECGs and 155 TTEs were completed, with 74 participants completing both. ECG evaluation showed high rates of left ventricular hypertrophy (LVH, 36.5%) and T wave abnormalities (13.6%). TTE evaluation showed high rates of concentric LVH (31.6%), with moderate-severe (56.8%) diastolic dysfunction. Participants with hypertension showed more cardiac remodeling on ECG by LVH (45.4% versus 22.1%, P<0.01), and TTE by concentric LVH (42.5% versus 8.2%, P<0.01) and increased left ventricular mass (58.5% versus 20.4%, P<0.0001). In multivariable logistic regression, systolic blood pressure remained significantly associated with LVH on ECG (adjusted odds ratio, 1.03 per mm Hg [95% CI, 1.03-1.04], P<0.0001) and increased left ventricular mass on TTE (adjusted odds ratio, 1.04 per mm Hg [95% CI, 1.01-1.06], P=0.001). Male participants (n=326, 40.2%) were more likely than females (n=484, 59.8%) to show ECG abnormalities like LVH (45% versus 30.8%, P<0.01), whereas females were more likely to show TTE abnormalities like concentric LVH (40.8% versus 13.5%, P<0.01) and increased left ventricular mass (58.4% versus 23.1%, P<0.0001). Similar results were confirmed in multivariable models.CONCLUSIONS: Our findings suggest that cardiovascular diseases are widespread in rural South Africa, with a larger burden of hypertensive heart disease than previously appreciated, and define the severity of end-organ damage that is already underway. Local health systems must adapt to face the growing burden of hypertension, as suboptimal rates of hypertension diagnosis and treatment may dramatically increase the heart failure burden.

Journal article (peer-reviewed)abstract
- BACKGROUND: The aim of this study was to describe out-of-hospital cardiac arrest (OHCA) survivors' ability to participate in activities of everyday life and society, including return to work. The specific aim was to evaluate potential effects of cognitive impairment. METHODS AND RESULTS: Two hundred eighty-seven OHCA survivors included in the TTM trial (Target Temperature Management) and 119 matched control patients with ST-segment-elevation myocardial infarction participated in a follow-up 180 days post-event that included assessments of participation, return to work, emotional problems, and cognitive impairment. On the Mayo-Portland Adaptability Inventory-4 Participation Index, OHCA survivors (n=270) reported more restricted participation In everyday life and in society (47% versus 30%; P<0.001) compared with ST-segment-elevation myocardial infarction controls (n=118). Furthermore, 27% (n=36) of pre-event working OHCA survivors (n=135) compared with 7% (n=3) of pre-event working ST-segment-elevation myocardial infarction controls (n=45) were on sick leave (odds ratio, 4.9; 95% confidence interval, 1.4-16.8; P=0.01). Among the OHCA survivors assumed to return to work (n=135), those with cognitive impairment (n=55) were 3x more likely (odds ratio, 3.3; 95% confidence interval, 1.2-9.3; P=0.02) to be on sick leave compared with those without cognitive impairment (n=40; 36%, n=20, versus 15%, n=6). For OHCA survivors, the variables that were found most predictive for a lower participation were depression, restricted mobility, memory impairment, novel problem-solving difficulties, fatigue, and slower processing speed. CONCLUSIONS: OHCA survivors reported a more restricted societal participation 6 months post-arrest, and their return to work was lower compared with ST-segment-elevation myocardial infarction controls. Cognitive impairment was significantly associated with lower participation, together with the closely related symptoms of fatigue, depression, and restricted mobility. These predictive variables may be used during follow-up to identify OHCA survivors at risk of a less successful recovery that may benefit from further support and rehabilitation.

- 2012
-
In: Circulation. Cardiovascular Quality and Outcomes. - 1941-7713 .- 1941-7705. ; 5:5, s. 680-688

Journal article (peer-reviewed)abstract
- Background-Elderly patients with acute coronary syndrome are at high risk of recurrent ischemic events and death, and for both antithrombotic therapy and catheter-based complications. This prespecified analysis investigates the effect and treatment-related complications of ticagrelor versus clopidogrel in elderly patients (>= 75 years of age) with acute coronary syndrome compared with those < 75 years of age. Methods and Results-The association between age and the primary composite outcome, as well as major bleeding were evaluated in the PLATelet inhibition and patient Outcomes (PLATO) trial using Cox proportional hazards. Similar models were used to evaluate the interaction of age with treatment effects. Hazard ratios were adjusted for baseline characteristics. The clinical benefit of ticagrelor over clopidogrel was not significantly different between patients aged >= 75 years of age (n=2878) and those < 75 years of age (n=15744) with respect to the composite of cardiovascular death, myocardial infarction, or stroke (interaction P=0.56), myocardial infarction (P=0.33), cardiovascular death (P=0.47), definite stent thrombosis (P=0.81), or all-cause mortality (P=0.76). No increase in PLATO-defined overall major bleeding with ticagrelor versus clopidogrel was observed in patients aged >= 75 years (hazard ratio, 1.02; 95% confidence interval, 0.82-1.27) or patients aged < 75 years (hazard ratio, 1.04; 95% confidence interval, 0.94-1.15). Dyspnea and ventricular pauses were more common during ticagrelor than clopidogrel treatment, with no evidence of an age-by-treatment interaction. Conclusions-The significant clinical benefit and overall safety of ticagrelor compared with clopidogrel in acute coronary syndrome patients in the PLATO cohort were not found to depend on age.

Risk of ischemic stroke after an acute myocardial infarction in patients with diabetes mellitus
- 2014
-

Journal article (peer-reviewed)abstract
- Background Incidence, any trend over time, and predictors of ischemic stroke after an acute myocardial infarction (AMI) in diabetic patients are unknown.Methods and Results Data for 173 233 unselected patients with an AMI, including 33 503 patients with diabetes mellitus, were taken from the Swedish Register of Information and Knowledge about Swedish Heart Intensive Care Admissions (RIKS-HIA) during 1998 to 2008. Ischemic stroke events were recorded during 1 year of follow-up. Patients with diabetes mellitus more often had a history of cardiovascular disease, received less reperfusion therapy, and were treated with acetylsalicylic acid, P2Y12 inhibitors, and statins to a lesser extent compared with patients without diabetes mellitus. However, the use of evidence-based therapies increased markedly in both groups during the study period. The incidence of ischemic stroke during the first year after AMI decreased from 7.1% to 4.7% in patients with diabetes mellitus and from 4.2% to 3.7% in patients without diabetes mellitus. Risk reduction was significantly larger in the diabetic subgroup. Reperfusion therapy, acetylsalicylic acid, P2Y12 inhibitors, and statins were independently associated with the reduced stroke risk.Conclusions Ischemic stroke is a fairly common complication after an AMI in patients with diabetes mellitus, but the risk of stroke has decreased during recent years. The increased use of evidence-based therapies contributes importantly to this risk reduction, but there is still room for improvement.

Journal article (peer-reviewed)abstract
- Background-The TRAPID-AMI trial study ( High-Sensitivity Troponin-T Assay for Rapid Rule-Out of Acute Myocardial Infarction) evaluated high-sensitivity cardiac troponin-T ( hs-cTnT) in a 1-hour acute myocardial infarction ( AMI) exclusion algorithm. Our study objective was to evaluate the prognostic utility of a modified HEART score ( m-HS) within this trial. Methods and Results-Twelve centers evaluated 1282 patients in the emergency department for possible AMI from 2011 to 2013. Measurements of hs-cTnT ( 99th percentile, 14 ng/L) were performed at 0, 1, 2, and 4 to 14 hours. Evaluation for major adverse cardiac events ( MACEs) occurred at 30 days ( death or AMI). Low-risk patients had an m-HS <= 3 and had either hs-cTnT<14 ng/L over serial testing or had AMI excluded by the 1-hour protocol. By the 1-hour protocol, 777 ( 60%) patients had an AMI excluded. Of those 777 patients, 515 ( 66.3%) patients had an m-HS <= 3, with 1 ( 0.2%) patient having a MACE, and 262 ( 33.7%) patients had an m-HS <= 4, with 6 ( 2.3%) patients having MACEs ( P=0.007). Over 4 to 14 hours, 661 patients had a hs-cTnT<14 ng/L. Of those 661 patients, 413 ( 62.5%) patients had an m-HS <= 3, with 1 ( 0.2%) patient having a MACE, and 248 ( 37.5%) patients had an m-HS >= 4, with 5 ( 2.0%) patients having MACEs ( P=0.03). Conclusions-Serial testing of hs-cTnT over 1 hour along with application of an m-HS identified a low-risk population that might be able to be directly discharged from the emergency department.

Dog Ownership and Survival After a Major Cardiovascular Event : A Register-Based Prospective Study
- 2019
-
In: Circulation. Cardiovascular Quality and Outcomes. - 1941-7713 .- 1941-7705. ; 12:10
-
Journal article (peer-reviewed)abstract
- Background: Dog ownership is associated with increased physical activity levels and increased social support, both of which could improve the outcome after a major cardiovascular event. Dog ownership may be particularly important in single-occupancy households where ownership provides substitutive companionship and motivation for physical activity.Methods and Results: We used the Swedish National Patient Register to identify all patients aged 40 to 85 presenting with an acute myocardial infarction (n=181 696; 5.7% dog ownership) or ischemic stroke (n=154 617; 4.8% dog ownership) between January 1, 2001 and December 31, 2012. Individual information was linked across registers for cause of death, sociodemographic, and dog ownership data. We evaluated all-cause mortality and risk of recurrent hospitalization for the same cause until December 31, 2012. Models were adjusted for socioeconomic, health, and demographic factors at study inclusion such as age, marital status, the presence of children in the home, area of residence, and income, as well as all registered comorbidities and hospitalization for cardiovascular disease in the past 5 years. Dog owners had a lower risk of death after hospitalization for acute myocardial infarction during the full follow-up period of 804 137 person-years, with an adjusted hazard ratio (HR) of 0.67 (95% CI, 0.61 to 0.75) for those who lived alone, and HR of 0.85 (95% CI, 0.80 to 0.90) for those living with a partner or a child. Similarly, after an ischemic stroke, dog owners were at lower risk of death during the full follow-up of 638 219 person-years adjusted HR of 0.73 (95% CI, 0.66 to 0.80) for those who lived alone and HR of 0.88 (95% CI, 0.83 to 0.93) for those living with a partner or a child. We further found an association of dog ownership with reduced risk of hospitalization for recurrent myocardial infarction (HR, 0.93; 95% CI, 0.87 to 0.99).Conclusions: We found evidence of an association of dog ownership with a better outcome after a major cardiovascular event. Although our models are adjusted for many potential confounders, there are also unmeasured confounders such as smoking that prevent us from drawing conclusions regarding a possible causal effect.

Survival in Patients With Suspected Myocardial Infarction With Nonobstructive Coronary Arteries : A Comprehensive Systematic Review and Meta-Analysis From the MINOCA Global Collaboration
- 2021
-
In: Circulation. Cardiovascular Quality and Outcomes. - : Lippincott Williams & Wilkins. - 1941-7713 .- 1941-7705. ; 14:11
-
Research review (peer-reviewed)abstract
- BACKGROUND: Suspected myocardial infarction (MI) with nonobstructive coronary arteries (MINOCA) occurs in ≈5% to 10% of patients with MI referred for coronary angiography. The prognosis of these patients may differ to those with MI and obstructive coronary artery disease (MI-CAD) and those without a MI (patients without known history of MI [No-MI]). The primary objective of this study is to evaluate the 12-month all-cause mortality of patients with MINOCA.METHODS: Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the terms "MI," "nonobstructive," "angiography," and "prognosis" were searched in PubMed and Embase databases from inception to December 2018, including original, English language MINOCA studies with >100 consecutive patients. Publications with a heterogeneous cohort, unreported coronary stenosis, or exclusively focusing on MINOCA-mimicking conditions, were excluded. Unpublished data were obtained from the MINOCA Global Collaboration. Data were pooled and analyzed using Paule-Mandel, Hartung, Knapp, Sidik & Jonkman, or restricted maximum-likelihood random-effects meta-analysis methodology. Heterogeneity was assessed using Cochran's Q and I2 statistics. The primary outcome was 12-month all-cause mortality in patients with MINOCA, with secondary comparisons to MI-CAD and No-MI.RESULTS: The 23 eligible studies yielded 55 369 suspected MINOCA, 485 382 MI-CAD, and 33 074 No-MI. Pooled meta-analysis of 14 MINOCA studies accounting for 30 733 patients revealed an unadjusted 12-month all-cause mortality rate of 3.4% (95% CI, 2.6%-4.2%) and reinfarction (n=27 605; 10 studies) in 2.6% (95% CI, 1.7%-3.5%). MINOCA had a lower 12-month all-cause mortality than those with MI-CAD (3.3% [95% CI, 2.5%-4.1%] versus 5.6% [95% CI, 4.1%-7.0%]; odds ratio, 0.60 [95% CI, 0.52-0.70], P<0.001). In contrast, there was a statistically nonsignificant trend towards increased 12-month all-cause mortality in patients with MINOCA (2.6% [95% CI, 0%-5.9%]) compared with No-MI (0.7% [95% CI, 0.1%-1.3%]; odds ratio, 3.71 [95% CI, 0.58-23.61], P=0.09).CONCLUSIONS: In the largest contemporary MINOCA meta-analysis to date, patients with suspected MINOCA had a favorable prognosis compared with MI-CAD, but statistically nonsignificant trend toward worse outcomes compared to those with No-MI.

Journal article (peer-reviewed)abstract
- BACKGROUND:The ongoing TANGO2 (Telephone Assisted CPR. AN evaluation of efficacy amonGst cOmpression only and standard CPR) trial is designed to evaluate whether compression-only cardiopulmonary resuscitation (CPR) by trained laypersons is noninferior to standard CPR in adult out-of-hospital cardiac arrest. This pilot study assesses feasibility, safety, and intermediate clinical outcomes as part of the larger TANGO2 survival trial.METHODS:Emergency medical dispatch calls of suspected out-of-hospital cardiac arrest were screened for inclusion at 18 dispatch centers in Sweden between January 1, 2017, and March 12, 2020. Inclusion criteria were witnessed event, bystander on the scene with previous CPR training, age above 18 years of age, and no signs of trauma, pregnancy, or intoxication. Cases were randomized 1:1 at the dispatch center to either instructions to perform compression-only CPR (intervention) or instructions to perform standard CPR (control). Feasibility included evaluation of inclusion, randomization, and adherence to protocol. Safety measures were time to emergency medical service dispatch CPR instructions, and to start of CPR, intermediate clinical outcome was defined as 1-day survival.RESULTS:Of 11 838 calls of suspected out-of-hospital cardiac arrest screened for inclusion, 2168 were randomized and 1250 (57.7%) were out-of-hospital cardiac arrests treated by the emergency medical service. Of these, 640 were assigned to intervention and 610 to control. Crossover from intervention to control occurred in 16.3% and from control to intervention in 18.5%. The median time from emergency call to ambulance dispatch was 1 minute and 36 s (interquartile range, 1.1–2.2) in the intervention group and 1 minute and 30 s (interquartile range, 1.1–2.2) in the control group. Survival to 1 day was 28.6% versus 28.4% (P=0.984) for intervention and control, respectively.CONCLUSIONS:In this national randomized pilot trial, compression-only CPR versus standard CPR by trained laypersons was feasible. No differences in safety measures or short-term survival were found between the 2 strategies. Efforts to reduce crossover are important and may strengthen the ongoing main trial that will assess differences in long-term survival.

Regional Patterns of Use of a Medical Management Strategy for Patients With Non-ST-Segment Elevation Acute Coronary Syndromes : Insights From the EARLY ACS Trial
- 2012
-

Journal article (peer-reviewed)abstract
- Background: Regional differences in the profile and prognosis of non-ST-segment elevation acute coronary syndrome (NSTE ACS) patients treated with medical management after angiography remain uncertain.Methods and Results: Using data from the Early Glycoprotein IIb/IIIa Inhibition in Non-ST-Segment Elevation Acute Coronary Syndromes (EARLY ACS) trial, we examined regional variations in the use of an in-hospital medical management strategy in NSTE ACS patients who had significant coronary artery disease (CAD) identified during angiography, factors associated with the use of a medical management strategy, and 1-year mortality rates. Of 9406 patients, 8387 (89%) underwent angiography and had significant CAD; thereafter, 1766 (21%) were treated solely with a medical management strategy (range: 18% to 23% across 4 major geographic regions). Factors most strongly associated with a medical management strategy were negative baseline troponin values, prior coronary artery bypass grafting, lower baseline hemoglobin values, and greater number of diseased vessels; region was not a significant factor. One-year mortality was higher among patients treated with a medical management strategy compared with those who underwent revascularization (7.8% versus 3.6%; adjusted hazard ratio, 1.46; 95% CI, 1.21-1.76), with no significant interaction by region (interaction probability value=0.42).Conclusions: Approximately 20% of NSTE ACS patients with significant CAD in an international trial were treated solely with an in-hospital medical management strategy after early angiography, with no regional differences in factors associated with medical management or the risk of 1-year mortality. These findings have important implications for the conduct of future clinical trials, and highlight global similarities in the profile and prognosis of medically managed NSTE ACS patients.

Journal article (peer-reviewed)abstract
- Background: Data on the association between quality of heart failure (HF) care and outcomes among patients with incident HF are sparse. We examined the association between process performance measures and clinical outcomes in patients with incident HF with reduced ejection fraction. Methods: Patients with incident HF with reduced ejection fraction (n=10 966) between January 2008 and October 2015 were identified from the Danish HF Registry. Data from public registries were linked. Multivariable regression analyses were used to assess the association between 6 guideline-recommended HF care processes (New York Heart Association assessment, use of angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, beta-blockers, and mineralocorticoid receptor antagonists, exercise training, and patient education) and all-cause and HF readmission, all-cause and HF hospital days, and mortality within 3 to 12 months after HF diagnosis. The associations were analyzed according to the percentages of all relevant performance measures fulfilled for the individual patient (0%-50% [reference group], >50%-75%, and >75%-100%) and for the individual performance measures. Results: Fulfilling >75% to 100% of the performance measures (n=5341 [48.7%]) was associated with lower risk of all-cause readmission (adjusted hazard ratio, 0.78 [95% CI, 0.68-0.89]) and HF readmission (adjusted hazard ratio, 0.71 [95% CI, 0.54-0.92]), lower use of all-cause hospital days (adjusted mean ratio, 0.73 [95% CI, 0.70-0.76]) and HF hospital days (adjusted mean ratio, 0.79 [95% CI, 0.70-0.89]), and lower mortality (adjusted hazard ratio, 0.42 [95% CI, 0.32-0.53]). A dose-response relationship was observed between fulfilling more performance measures and mortality (adjusted hazard ratio, 0.62 [95% CI, 0.49-0.77] fulfilling >50%-75% of the measures). Fulfilling individual performance measures, except mineralocorticoid receptor antagonist therapy, was associated with lower adjusted all-cause readmission, lower adjusted use of all-cause and HF hospital days, and lower adjusted mortality. Conclusions: Fulfilling more process performance measures was associated with better clinical outcomes in patients with incident HF with reduced ejection fraction.

Journal article (peer-reviewed)abstract
- BACKGROUND: The contemporary impact of heart failure (HF) versus the most common forms of cancer as reflected by related first-ever hospitalizations and subsequent case-fatality rates is unknown. METHODS AND RESULTS: Using a national registry in Sweden, we compared the rate of first-ever hospitalization and associated short- and long-term survival for HF, acute myocardial infarction (AMI), and the most common forms of cancer on an age and sex-specific basis during 1988 to 2004 in 949 733 Swedish patients (1 162 309 hospital admissions in total). Annual incidence of first-ever hospitalization for HF, AMI, and cancer in Sweden were 484, 424, and 373 (lung, colorectal, prostate, and bladder cancer combined) per 100 000 men and 470, 280, and 350 (lung, colorectal, bladder, breast, and ovarian cancer combined) per 100 000 women age >20 years. The ratio of individual cases of HF to cancer was 1.37:1 (465 998 versus 340 738). Despite improvements in 30-day and 5-year survival (adjusted 7% and 6% increase per calendar year for men and women, respectively), HF was associated with unadjusted case-fatality rate of 59% within 5 years and 196 400 deaths versus 58% and 131 000 deaths in patients with cancer. During 10-year follow-up, HF was associated with 66 318 versus 55 364 premature life-years lost than all common forms of cancer in men. In women, the equivalent figures were 59 535 versus 64 533 premature life-years lost. CONCLUSIONS: These data confirm that, like most common forms of cancer combined, HF exerts a major health burden in respect to age-adjusted rates of first hospitalization, poor overall survival, and premature life-years lost.

Treatments and Mortality Trends in Cases With and Without Dialysis Who Have an Acute Myocardial Infarction : An 18-Year Nationwide Experience
- 2019
-
In: Circulation. Cardiovascular Quality and Outcomes. - 1941-7713 .- 1941-7705. ; 12:9
-
Journal article (peer-reviewed)abstract
- Background: Patients on dialysis who have an acute myocardial infarction (AMI) have an exceedingly poor prognosis, but it is unknown to what extent guideline-recommended interventions and treatments are used and to which benefit. We aimed to assess temporal changes in the use of treatments and survival rates in dialysis patients with an AMI.Methods and Results: All consecutive AMI cases from 1996 to 2013 enrolled in the SWEDEHEART registry (Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies) were included. The Swedish Renal Registry identified all chronic dialysis cases. Multivariable adjusted standardized 1-year mortality was estimated. An age-sex-calendar year-matched dialysis background population from the Swedish Renal Registry was used to obtain a standardized incidence ratio. All analyses were performed in 2-year blocks, where each individual could be included several times but in different time blocks; hence the term AMI cases and not patients is used. Of 289 699 cases with AMI, 1398 (0.5%) were on dialysis (73.6% hemodialysis; 26.4% peritoneal dialysis). Among dialysis cases, 29.4% were women, and 21.0% had ST-segment-elevation myocardial infarction. Through 1996 to 2013, dialysis cases had similar age (median, 70 years [interquartile range, 62-77]; P for trend, 0.14), but the proportion with diabetes mellitus increased (36.0%-55.3%; P for trend, 0.005). Dialysis cases admitted with AMI were treated more invasively and received more discharge medications in the later years. From 1995 to 2013, in-hospital and 1-year mortality decreased from 25.4% to 9.4% and from 59.6% to 41.2%, respectively. The standardized in-hospital and 1-year mortality decreased from 25.7% to 9.4% and from 54.6% to 41.2%. Yet, compared with the matched dialysis population, the odds of death remained as high in 2012/2013 as in 1996/1997 (odds ratio, 2.04; 95% CI, 1.62-2.58 and odds ratio, 1.99; 95% CI, 1.52-2.60, respectively; P for trend, 0.34).Conclusions: Over the last 18 years, more patients on dialysis with AMI have been treated with evidence-based therapies. Overall, dialysis cases with AMI have an improved in-hospital and 1-year survival in the more recent years compared with earlier years. However, this appears largely to be because of improved survival in the general dialysis population.

Circulating 25-hydroxy-vitamin d and risk of cardiovascular disease : a meta-analysis of prospective studies

- BackgroundVitamin D status has been linked to the risk of cardiovascular disease (CVD). However, the optimal 25-hydroxy-vitamin D (25[OH]-vitamin D) levels for potential cardiovascular health benefits remain unclear.Methods and ResultsWe searched MEDLINE and EMBASE from 1966 through February 2012 for prospective studies that assessed the association of 25(OH)-vitamin D concentrations with CVD risk. A total of 24 articles met our inclusion criteria, from which 19 independent studies with 6123 CVD cases in 65 994 participants were included for a meta-analysis. In a comparison of the lowest with the highest 25(OH)-vitamin D categories, the pooled relative risk was 1.52 (95% confidence interval, 1.30-1.77) for total CVD, 1.42 (95% confidence interval, 1.19-1.71) for CVD mortality, 1.38 (95% confidence interval, 1.21-1.57) for coronary heart disease, and 1.64 (95% confidence interval, 1.27-2.10) for stroke. These associations remained strong and significant when analyses were limited to studies that excluded participants with baseline CVD and were better controlled for season and confounding. We used a fractional polynomial spline regression analysis to assess the linearity of dose-response association between continuous 25(OH)-vitamin D and CVD risk. The CVD risk increased monotonically across decreasing 25(OH)-vitamin D below ≈60 nmol/L, with a relative risk of 1.03 (95% confidence interval, 1.00-1.06) per 25-nmol/L decrement in 25(OH)-vitamin D.ConclusionsThis meta-analysis demonstrated a generally linear, inverse association between circulating 25(OH)-vitamin D ranging from 20 to 60 nmol/L and risk of CVD. Further research is needed to clarify the association of 25(OH)-vitamin D higher than 60 nmol/L with CVD risk and assess causality of the observed associations.

- Background Epidemiological data on the risk of intracranial hemorrhage (ICrH) after ischemic stroke are sparse. The aims of this study were to describe incidence, trends over time, and predictors of ICrH within 1 year after ischemic stroke. Methods and Results All patients registered in the Swedish stroke register Riksstroke for 1998 to 2009 were included (n=196 765), and data were combined with the National Patient Register to identify ICrH occurrence. A matched reference population was obtained. Incidence rates and cumulative incidences were calculated. Multivariable regression analyses were used to identify predictors. Analyses were performed separately for the first 30 days and days 31 to 365 after ischemic stroke. The incidence rate was 1.97% per year at risk for the first year (0.13% in the reference population) and 0.85% excluding the first 30 days. Over time, the cumulative incidence increased the first 30 days but decreased over days 31 to 365. Thrombolysis, previous ICrH, atrial fibrillation, and male sex were associated with increased risk of ICrH during the first 30 days. Previous ICrH, increasing age, and male sex were associated with increased risk during days 31 to 365. Statins and antithrombotic treatment did not independently predict ICrH occurrence. Conclusions The incidence of ICrH within 1 year after ischemic stroke was approximate to 2% per year at risk, about 15 times higher compared with the reference population. Over the study period, ICrH risk increased within the first 30 days but decreased thereafter. Previous ICrH, thrombolysis, and male sex affected the risk, whereas an increased use of antithrombotic treatments and statins did not.

Improved clinical outcome after acute myocardial infarction in hospitals participating in a Swedish quality improvement initiative
- 2009
-
In: Circulation. Cardiovascular quality and outcomes. - 1941-7713. ; 2:5, s. 458-464
-
Journal article (peer-reviewed)abstract
- BACKGROUND: The Swedish quality improvement initiative Quality Improvement in Coronary Care previously demonstrated significant improvements in caregiver adherence to national guidelines for acute myocardial infarction. The associated impact on 1-year clinical outcome is presented here. METHODS AND RESULTS: During the baseline period July 2001 to June 2002, 6878 consecutive acute myocardial infarction patients <80 years were included at the 19 intervention and 19 control hospitals and followed for a mean of 12 months. During the postintervention period of May 2003 to April 2004, 6484 patients were included and followed in the same way. From baseline to postintervention, improvements in mortality and cardiovascular readmission rates (events per 100 patient-years) were significant in the intervention group (-2.82, 95% CI -5.26 to -0.39; -9.31, 95% CI -15.48 to -3.14, respectively). However, in the control hospitals, there were no significant improvements (0.04, 95% CI -2.40 to 2.47; -4.93, 95% CI -11.10 to 1.24, respectively). Bleedings in the control group increased in incidence (0.92, 95% CI 0.41 to 1.43), whereas the incidence remained unchanged in the intervention group (0.07, 95% CI -0.44 to 0.58). When the difference of changes between the study groups were evaluated, the results still were in favor of the intervention group, albeit significant only for bleeding complications (mortality: -2.70, 95% CI -6.37 to 0.97; cardiovascular readmissions: -6.85, 95% CI -16.62 to 2.93; bleeding complications: -0.82, 95% CI -1.66 to 0.01). CONCLUSIONS: With a systematic quality improvement initiative aiming to increase the adherence to acute myocardial infarction guidelines, it is possible to achieve long-term positive effects on clinical outcome.

Hazard Function and Secular Trends in the Risk of Recurrent Acute Myocardial Infarction : 30 Years of Follow-Up of More Than 775 000 Incidents
- 2009
-
In: Circulation: Cardiovascular Quality and Outcomes. - 1941-7713. ; 2:3, s. 175-185
-
Journal article (peer-reviewed)abstract
- Background—The incidence of a first acute myocardial infarction (AMI) has fallen considerably during the last decades. However, no previous studies have analyzed the underlying hazards function of experiencing a recurrent AMI, and none has analyzed the change of risk for a recurrent AMI over the last 3 decades. Methods and Results—The study was based on the Swedish national myocardial infarction register. The register contained more than 1 million AMI events. After exclusion of events occurring in subjects younger than 20 or older than 84 years and events with uncertain first AMI status, 775 901 events occurring between 1972 and 2001 remained for analysis. During the study period, the risk of a new event among survivors of a previous AMI decreased sharply during the first 2 years after the previous event, had its minimum after 5 years, and then increased slowly again. The risk for a recurrent AMI during the first year after a previous event was fairly stable over the years until the late 1970s and then decreased by 36% in women and 40% in men until the late 1990s, irrespective of age and AMI number, mirroring the incidence decrease over the years for primary events. Conclusions—The risk of a recurrent AMI event was highly dependent on time from the previous event, a novel finding which may affect risk scoring. There were strong secular trends toward diminishing risk for a recurrent AMI in recent years, even when other outcome affecting variables were taken into account.

Return to Work and Participation in Society after Out-of-Hospital Cardiac Arrest
- 2018
-
In: Circulation. Cardiovascular Quality and Outcomes. - 1941-7713. ; 11:1, s. 1-11
-
Journal article (peer-reviewed)abstract
- Background: The aim of this study was to describe out-of-hospital cardiac arrest (OHCA) survivors' ability to participate in activities of everyday life and society, including return to work. The specific aim was to evaluate potential effects of cognitive impairment. Methods and Results: Two hundred eighty-seven OHCA survivors included in the TTM trial (Target Temperature Management) and 119 matched control patients with ST-segment-elevation myocardial infarction participated in a follow-up 180 days post-event that included assessments of participation, return to work, emotional problems, and cognitive impairment. On the Mayo-Portland Adaptability Inventory-4 Participation Index, OHCA survivors (n=270) reported more restricted participation In everyday life and in society (47% versus 30%; P<0.001) compared with ST-segment-elevation myocardial infarction controls (n=118). Furthermore, 27% (n=36) of pre-event working OHCA survivors (n=135) compared with 7% (n=3) of pre-event working ST-segment-elevation myocardial infarction controls (n=45) were on sick leave (odds ratio, 4.9; 95% confidence interval, 1.4-16.8; P=0.01). Among the OHCA survivors assumed to return to work (n=135), those with cognitive impairment (n=55) were 3× more likely (odds ratio, 3.3; 95% confidence interval, 1.2-9.3; P=0.02) to be on sick leave compared with those without cognitive impairment (n=40; 36%, n=20, versus 15%, n=6). For OHCA survivors, the variables that were found most predictive for a lower participation were depression, restricted mobility, memory impairment, novel problem-solving difficulties, fatigue, and slower processing speed. Conclusions: OHCA survivors reported a more restricted societal participation 6 months post-arrest, and their return to work was lower compared with ST-segment-elevation myocardial infarction controls. Cognitive impairment was significantly associated with lower participation, together with the closely related symptoms of fatigue, depression, and restricted mobility. These predictive variables may be used during follow-up to identify OHCA survivors at risk of a less successful recovery that may benefit from further support and rehabilitation.
