Abstract:
:To evaluate the therapeutic efficacy of oral angiotensin-converting inhibition (ACE) with captopril in chronic normotensive congestive heart failure (CHF), acute and cardiocirculatory actions were determined by cardiac catheterization and forearm plethysmography, and ambulatory effects were assessed by echocardiography, nuclear angiography, treadmill exercise, and clinical symptomatology in 10 severe CHF patients. Captopril (90 mg) produced marked (peak 1 hour) and sustained (5 hours) left ventricular filling pressure (23 to 15 mm Hg), systemic vascular resistance decreases, and cardiac index increase (1.99 to 2.41 L/min/m2), while mean blood pressure declined mildly (87 to 80 mm Hg) without heart rate change. Both forearm venous tone and vascular resistance decreased considerably. After 1 week of ambulatory therapy (90 mg three times daily), nuclear angiographic ejection and echocardiogram shortening fractions increased, and exercise duration (341 to 453 sec) and New York Heart Association functional class (3.6 to 2.2) improved. Thus ACE-induced vasodilation by oral captopril improved cardiac performance and clinical status in refractory CHF.
