  • Look Inside

To study the effect of bunazosin on exercise capacity in patients with congestive heart failure (NYHA Ⅱ-Ⅲ), anaerobic thresholds (AT, V02, ml/min/kg) were measured before (control) and after initial 1=2mg administration of bunazosin (acute phase ; N=14) and after two weeks of bunazosin therapy (3mg/day, 1mg t. i. d., chronic phase ; N=6). AT were determined by Wasserman's V-slope method during ergometer exer-cise test with a ramp loading (10 watt/min). AT in-creased significantly from control during both acute (14.2±2.7 to 16.9±3.6 ml/min/kg p<0.005) and chronic (13.6±2.5 to 16.7±1.0 p<0.05) phase.
