Core Tip
Core tip: Heart failure (HF) has preserved left ventricular ejection fraction (HFpEF) accounts for approximately 50% of all patients diagnosed with HF, with similary poor outcomes. To date, only the prevention of HFpEF by treating the cardiovascular risk factors (coronary artery disease, atrial fibrillation, hypertension, diabetes, and obesity) has been shown to be efficient. This observation suggests that investigators in future trials should specify the indication of hospitalization for HF and may request to verify the details of patients’ admissions. We provide an outline and interpretation of recent clinical trials that failed to improve outcome and survival in patients with HF with preserved ejection fraction.
