Systolic and diastolic dysfunction in indeterminate, digestive and chronic cardiac forms of Chagas' disease


, : Systolic and diastolic dysfunction in indeterminate, digestive and chronic cardiac forms of Chagas' disease. Arquivos Brasileiros de Cardiologia 50(5): 293-299

Cardiovascular effects of isometric exercise were studied in 14 normal volunteers and in 40 patients with chronic Chagas' disease, i.e. 14 in the indeterminate phase, 14 with the chronic cardiac form and 12 presenting only clinical and laboratory findings of megaoesophagus and/or megacolon (digestive form). In the baseline situation, all groups showed similar heart rate and blood pressure. Only in the cardiac group was a significant impairment of systolic function detected at rest.
