Abstrakt: Background and Objective: Patients with heart failure are classified into three phenotypes based on left ventricular ejection fraction. This work aimed to compare the clinical profile, treatment, prognosis, and causes of death of patients with heart failure and reduced (<40%, HF-rEF), preserved (≥50%, HF-pEF), or mid-range (40-49%, HF-mrEF) left ventricular ejection fraction.
Methods: An analysis was conducted on the clinical data included in a prospective registry of patients with heart failure who were referred to a specific Cardiology unit from 2010 to 2019.
Results: A total of 1404 patients with HF-rEF, 239 patients with HF-mrEF, and 266 patients with HF-pEF were analyzed. Significant differences were observed among the groups in regard to several clinical characteristics and the frequency of prescription of neurohormonal blocking drugs. A multivariate Cox regression revealed an increased risk of all-cause mortality in patients with HF-pEF (hazard ratio 1.36; 95% confidence interval 1.03-1.80; p = 0.028) and patients with HF-mrEF (hazard ratio 1.36; 95% confidence interval 1.03-1.78; p = 0.029) as compared to patients with HF-rEF. Heart failure was the most frequent cause of death in the three subgroups. A higher relative weight of sudden death as a cause of death was observed among patients with HF-rEF while the relative weight of non-cardiovascular causes of death was higher among patients with HF-pEF and HF-mrEF.
Conclusions: This study confirms the existence of significant differences among patients with HF-rEF, HF-mrEF, and HF-pEF with regard to their clinical profile, therapeutic management, prognosis, and causes of death.
