Abstract

Heart failure (HF) with preserved ejection fraction (HFPEF) is still a challenge in clinical practice. The prognosis of patients with HFPEF is similar to or only slightly better than that of patients with HF with reduced ejection fraction (HFREF). Impaired relaxation is the mildest form of diastolic dysfunction, which should not be accompanied by symptoms of HFPEF. The aim of the study was to assess the incidence of chronic HFPEF in patients with hypertension and isolated mild diastolic dysfunction. It was a cross-sectional study including 210 patients (mean age, 56.11 ±6.24 years; women, 58%) with isolated abnormalities of left ventricular relaxation and arterial hypertension. In addition, we identified patients with type 2 diabetes to compare the incidence of HFPEF between patients with and without diabetes. HFPEF was diagnosed when clinical symptoms of HF were present simultaneously with echocardiographic markers of elevated left ventricular diastolic pressure, pulmonary congestion on chest X-ray, or elevated serum brain natriuretic peptide (BNP) levels. HFPEF was diagnosed in 42% of the patients with impaired relaxation. An elevated left atrial volume index (>34 ml/m²) was observed in 38% of the patients; E/e' ratio exceedi...Continue Reading
