Abstract
Cardiovascular responses to static-dynamic exercises were studied in 2 7 patients with recent myocardial infarction. Patients with ischemic e lectrocardiographic changes at peak weight carrying exercise (group 1 = 8 patients) had a significantly larger left ventricular end-diastoli c volume than those without (group 2 = 19 patients), A higher tension time index and shortening of diastolic time/min was observed in group I compared to group 2 during weight carrying. Thus, in addition to the increased myocardial oxygen demand, shortening of the diastolic perfu sion time was observed during static-dynamic exercise in patients with dilated heart after myocardial infarction.
