Characteristics and outcomes for patients with heart failure diagnosed according to the universal definition and classification of heart failure. Data from a single-center registry

WHAT'S NEW?We compared baseline characteristics, hospital readmission, and mortality rates in individuals with heart failure (HF) with reduced (HFrEF), mildly reduced (HFmrEF), and preserved (HFpEF) ejection fraction diagnosed according to the universal definition and classification of HF.According to our knowledge, this is the first publication that used the universal definition and classification of HF to classify HF groups.Moreover, HF screening was performed in all patients hospitalized in the cardiac department, regardless of previous HF diagnosis.Our study showed that the all-cause mortality was higher than the urgent HF readmission rates in all HF groups, regardless of the left ventricular ejection fraction.
