Gender-related differences in heart failure with preserved ejection fraction.

ABSTRACT: Heart failure with preserved ejection fraction (HFpEF) affects more women than men, suggesting gender to play a major role in disease evolution. However, studies investigating gender differences in HFpEF are limited. In the present study we aimed to describe gender differences in a well-characterized HFpEF cohort. Consecutive HFpEF patients underwent invasive hemodynamic assessment, cardiac magnetic resonance imaging and exercise testing. Study endpoints were: cardiac death, a combined endpoint of HF hospitalization or cardiac death and all-cause death. 260 HFpEF patients were prospectively enrolled. Men were more compromised with regard to exercise capacity and had significantly more co-morbidities. Men had more pronounced pulmonary vascular disease with higher diastolic pressure gradients and a lower right ventricular EF. During follow-up, 9.2% experienced cardiac death, 33.5% the combined endpoint and 17.3% all-cause death. Male gender was independently associated with cardiac death, but neither with the combined endpoint nor with all-cause mortality. We detected clear gender differences in HFpEF patients. Cardiac death was more common among men, but not all-cause death. While men are more prone to develop a right heart phenotype and die from HFpEF, women are more likely to die with HFpEF.

Project description:Background The female preponderance in heart failure with preserved ejection fraction (HFpEF) is a distinguishing feature of this disorder, but the association of sex with degree of diastolic dysfunction and clinical outcomes among individuals with HFpEF remains unclear. Methods and Results We conducted a prospective, multicenter, observational study of patients with HFpEF (PURSUIT-HFpEF [Prospective Multicenter Observational Study of Patients with Heart Failure with Preserved Ejection Fraction]: UMIN000021831). Between 2016 and 2019, 871 patients were enrolled from 26 hospitals (follow-up: 399±349 days). We investigated sex-related differences in diastolic dysfunction and postdischarge clinical outcomes in patients with HFpEF. The echocardiographic end point was diastolic dysfunction according to American Society of Echocardiography/European Association of Cardiovascular Imaging criteria. The clinical end point was a composite of all-cause death and heart failure readmission. Women accounted for 55.2% (481 patients) of the overall cohort. Compared with men, women were older and had lower prevalence rates of hypertension, coronary artery disease, and chronic kidney disease. Women had diastolic dysfunction more frequently than men (52.8% versus 32.0%, P<0.001). The incidence of the clinical end point did not differ between women and men (women 36.1/100 person-years versus men 30.5/100 person-years, P=0.336). Female sex was independently associated with the echocardiographic end point (adjusted odds ratio, 2.839; 95% CI, 1.884-4.278; P<0.001) and the clinical end point (adjusted hazard ratio, 1.538; 95% CI, 1.143-2.070; P=0.004). Conclusions Female sex was independently associated with the presence of diastolic dysfunction and worse clinical outcomes in a cohort of elderly patients with HFpEF. Our results suggest that a sex-specific approach is key to investigating the pathophysiology of HFpEF. Registration URL: https://upload.umin.ac.jp; Unique identifier: UMIN000021831.

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.
