    Abstract:
    Technetium-99m pertechnetate equilibrium ventriculography was used to evaluate the effects of captopril in a single dose of 50 mg on the changes in ST segment depression during the identical bicycle ergometer exercise, as well as on systemic and regional hemodynamic parameters in 10 patients (mean age 52 years) with Functional Classes II-III exercise-induced angina pectoris. During exercise performed 45 and 90 minutes after captopril, ST segment depression decreased by 30 +/- 0 (p less than 0.05), and 32 +/- 10% (p less than 0.02), respectively as compared to baseline ST segment displacement. Following 90 minutes after the drug administration, end-systolic volume reduced both at rest and during exercise, resting stroke volume increased from 71 +/- 4 to 76 +/- 4 ml (p less than 0.01), whereas exercise stroke volume rose from 69 +/- 3 to 74 +/- 3 ml (p less than 0.03); with the drug, ejection fraction showed a 5% increase (p less than 0.02) at rest and a 4% increase (p less than 0.02) on exercise. Thus, captopril had a beneficial effect on the hemodynamics and reduced myocardial ischemia in patients with exercise induced angina.
