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.
