Study of the clinical and epidemiological profile of heart failure

Abstract

The purpose was to describe the clinical and epidemiological profile of patients with Heart Failure (HF) treated at a specialized clinic in the Unified Health System. This is a descriptive, individual and cross-sectional study, which collected data from medical records of patients with HF. Patients were divided into three groups according to the stroke volume: preserved, mid-range and reduced. A total of 545 medical records were evaluated, with a mean age of 64.9 ± 13.6 years, and 55.6% of which were male. Hypertension (76.7%), coronary artery disease (38.5%), and diabetes mellitus (37.2%) were the main risk factors. Myocardial ischemia was the main etiology (36.40%), followed by Chagas disease (20.22%). The valve etiology was frequently associated with reduced LVEF (left ventricular ejection fraction) (Pearson's ρ <0.06), with mid-range LVEF (Pearson's ρ <0.10) and with preserved LVEF (Pearson's ρ <0.39). The ischemic etiology was frequent in preserved LVEF (Pearson's ρ <0.08). The findings showed a strong association between valve disease and preserved LVEF; frequent association between mid-range LVEF and valve and ischemic disease; frequent association between valve disease and reduced LVEF.
