Age differences in contemporary treatment of patients with chronic heart failure and reduced ejection fraction.

ABSTRACT:

Background

Elderly patients are underrepresented in clinical trials but comprise the majority of heart failure patients. Data on age-specific use of heart failure therapy are limited. The European Society of Cardiology heart failure guidelines provide no age-specific treatment recommendations. We investigated practice-based heart failure management in a large registry at heart failure outpatient clinics.

Design and methods

We studied 8351 heart failure with reduced ejection fraction patients at 34 Dutch outpatient clinics between 2013 and 2016. The mean age was 72.3?±?11.8 years and we divided age into three categories: less than 60 years (13.9%); 60-74 years (36.0%); and 75 years and over (50.2%).

Results

Elderly heart failure with reduced ejection fraction patients (?75 years) received significantly fewer beta-blockers (77.8% vs. 84.2%), renin-angiotensin system inhibitors (75.2% vs. 89.7%), mineralocorticoid receptor antagonists (50.6% vs. 59.6%) and ivabradine (2.9% vs. 9.3%), but significantly more diuretics (88.1% vs. 72.6%) compared to patients aged less than 60 years (P_{for all trends}?ConclusionWith increasing age, heart failure with reduced ejection fraction patients less often received guideline-recommended medication prescriptions and also in a lower dosage. In addition, a lower percentage of implantable cardioverter defibrillator and cardiac resynchronisation therapy device implantation in elderly patients was observed.

Project description:BackgroundLifetime risk of heart failure has been estimated to range from 20% to 46% in diverse sex and race groups. However, lifetime risk estimates for the 2 HF phenotypes, HF with preserved ejection fraction (HFpEF) and HF with reduced ejection fraction (HFrEF), are not known.MethodsParticipant-level data from 2 large prospective cohort studies, the CHS (Cardiovascular Health Study) and MESA (Multiethnic Study of Atherosclerosis), were pooled, excluding individuals with prevalent HF at baseline. Remaining lifetime risk estimates for HFpEF (EF ≥45%) and HFrEF (EF <45%) were determined at different index ages with the use of a modified Kaplan-Meier method with mortality and the other HF subtype as competing risks.ResultsWe included 12 417 participants >45 years of age (22.2% blacks, 44.8% men) who were followed up for median duration of 11.6 years with 2178 overall incident HF events with 561 HFrEF events and 726 HFpEF events. At the index age of 45 years, the lifetime risk for any HF through 90 years of age was higher in men than women (27.4% versus 23.8%). Among HF subtypes, the lifetime risk for HFrEF was higher in men than women (10.6% versus 5.8%). In contrast, the lifetime risk for HFpEF was similar in men and women. In race-stratified analyses, lifetime risk for overall HF was higher in nonblacks than blacks (25.9% versus 22.4%). Among HF subtypes, the lifetime risk for HFpEF was higher in nonblacks than blacks (11.2% versus 7.7%), whereas that for HFrEF was similar across the 2 groups. Among participants with antecedent myocardial infarction before HF diagnosis, the remaining lifetime risks for HFpEF and HFrEF were up to 2.5-fold and 4-fold higher, respectively, compared with those without antecedent myocardial infarction.ConclusionsLifetime risks for HFpEF and HFrEF vary by sex, race, and history of antecedent myocardial infarction. These insights into the distribution of HF risk and its subtypes could inform the development of targeted strategies to improve population-level HF prevention and control.

Project description:Objectives:This study sought to determine whether age modifies the impact of key comorbidities on clinical outcomes for patients with heart failure with reduced ejection fraction (HFrEF).Background:Comorbidities impact outcomes in HFrEF. However, the effect of age on the impact of comorbidities on prognosis is not clearly understood.Methods:Cox proportional hazards models were used assessed interactions between age and comorbidities on the primary composite endpoint (all-cause mortality or hospitalization) and secondary endpoints in the HF-ACTION (Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training) multicenter trial of 2,331 patients with HFrEF.Results:Age did not significantly modify the effect of any comorbidity on the primary endpoint. However, age significantly modified the effect of body mass index (BMI) on all-cause mortality (interaction p = 0.02). Among patients ?70 years of age, there was a U-shaped relationship between BMI and 1-year mortality, where BMI of 20 kg/m2 corresponded to 17.6%; a BMI of 30 kg/m2 corresponded to 7.0%; and a BMI of 40 kg/m2 corresponded to 11%. For patients <60 years of age, mortality increased nonsignificantly from 3.2% to 3.7% with increasing BMI. Age also modified the effect of depressive symptoms on all-cause mortality (interaction p = 0.03). Among patients ?70 years of age, a 1-year mortality rate significantly increased from 7.8% for a Beck Depression Inventory (BDI) score of 5% to 15.6% for BDI of 20. For patients <60 years of age, mortality was nonsignificantly related to BDI. Cumulative comorbidity scores were stronger predictors than age for mortality/hospitalization.Conclusions:In chronic HFrEF, age markedly altered the impact of BMI and depressive symptoms on all-cause mortality, with much higher risk in older patients, but was not as strong a predictor of mortality/hospitalizations as cumulative comorbidity score.

Project description:IntroductionA worsening heart failure event (WHFE) is defined as progressively escalating heart failure signs/symptoms requiring intravenous diuretic treatment or hospitalization. No studies have compared the burden of chronic heart failure with reduced ejection fraction (HFrEF) following a WHFE versus stable disease to inform healthcare decision makers.MethodsA retrospective study using the IBM® MarketScan® Commercial Database included patients younger than 65 years of age with HFrEF (one inpatient or two outpatient claims of systolic HF or one outpatient claim of systolic HF plus one outpatient claim of any HF). The first claim for HFrEF during 2016 was the index date. Patients were followed for the first 12 months after the index date (the worsening assessment period) to identify a WHFE, and for an additional 12 months or until the end of continuous enrollment (the post-worsening assessment period). Mean per patient per month (PPPM) health care resource use (HCRU) and costs were compared between patients following a WHFE and stable patients during the two periods using generalized linear models adjusting for patient characteristics.ResultsOf 16,646 patients with chronic HFrEF, 26.8% developed a WHFE. Adjusted all-cause hospitalizations (0.16 vs. 0.02 PPPM, P < 0.0001), outpatient visits (3.54 vs. 2.73 PPPM, P < 0.0001), and emergency department visits (0.25 vs. 0.06 PPPM, P < 0.0001) were higher in patients following a WHFE than stable patients during the worsening assessment period. Similar differences in HCRU were observed between the two cohorts during the post-worsening assessment period. Mean total adjusted cost of care PPPM was $8657 in patients with HFrEF following a WHFE versus $2195 in stable patients during the worsening assessment period, and $6809 versus $2849, respectively, during the post-worsening assessment period.ConclusionHCRU and costs were significantly greater in patients with chronic HFrEF following a WHFE compared to those who remained stable, suggesting an unmet need to improve clinical and economic outcomes among these patients.
