Objectives: The aim of this study was to determine the prevalence of heart failure (HF) in adult residents of Turkey based on echocardiography and N-terminal B type natriuretic factor. Study design: 4650 randomly selected residents aged ≥35 years were enrolled. Height, weight, waist and hip circumference, and blood pressure measurements were taken, and a 12-lead ECG was performed. Advanced age, hypertension (HT), diabetes mellitus (DM), obesity, and chronic renal failure (CRF) were assessed. History of any heart disease, any abnormal ECG, or an NT-proBNP ≥120 pg/mL was accepted as echocardiography indication. Patients with systolic and/or diastolic dysfunction, or NT-proBNP ≥2000 pg/mL were classified as having HF if their functional capacity was NYHA ≥Class II, and were classified as having asymptomatic left ventricular dysfunction (ASVD) if their functional capacity was NYHA
