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. MethodsAn 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. ResultsA 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. ConclusionsThis 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.
