Obesity and Diabetes Mellitus as Risk Factors of one Year Mortality in Patients with unstable Angina

Abstract

The short-term prognosis of patients with unstable angina is determined by the severity of ischemia and of the coronary disease, and in the long term by the intervention of the cardiovascular risk factors. Recently published data shows controversial results between the influence of obesity and glycated hemoglobin on the prognosis of patients with acute coronary syndromes. This observational and prospective study evaluates the influence of cardiovascular risk factors in 140 patients hospitalized for unstable angina on the mortality risk during one year of surveillance. The risk of death in patients with unstable angina at one-year follow-up was significantly influenced by age over 75 years, previous documented coronary heart disease, diabetes mellitus, high plasma values of glycated hemoglobin (Hb1Ac), and low values of estimated glomerular filtration rate (eGRF). The high body mass index and the waist circumference did not correlate with the risk of death at the one-year follow-up of patients with unstable angina.
