We know that obesity is a risk factor for heart failure, but we do not know whether this risk appears through a diastolic dysfunction, so some researchers in the USA have studied a cohort of 950 patients (averagely 72 years of age) through echocardiography. The incidence of diastolic dysfunction [...]
