Influence of Etiology on heart failure With Preserved Systolic function Mortality in a Population With high Prevalence of Chagas Cardiomyopathy

Background Heart failure with preserved systolic function is a clinical syndrome with the same signs and symptoms of classic heart failure. Chagas disease is a major cause of heart failure in Latin America, associated with dilated cardiomyopathy and progressive deterioration of systolic function. There are no previous assessment studies of patients with heart failure and preserved systolic function in an endemic area in which Chagas disease is the leading cause of heart failure.
