    Abstract:
    Numerous pharmacologic agents are capable of lowering the blood pressure of hypertensive patients; however, each drug has a characteristic side effect profile and effect on cardiac performance. In this study, the hemodynamic effects of the angiotensin converting enzyme inhibitor fosinopril were assessed at rest and at peak upright bicycle exercise by first-pass radionuclide cineangiography in 12 patients with essential hypertension. Fosinopril reduced blood pressure at rest in the seated position from 152/101 to 131/85 mm Hg (P less than .01) and at peak exercise from 206/103 to 184/91 mm Hg (P less than .01). Fosinopril therapy was associated with an increase in stroke volume and cardiac output and a decrease in systemic vascular resistance at rest and during peak exercise. Both peak ejection rate and peak filling rate increased significantly at rest during fosinopril therapy. The unique cardiotropic response to fosinopril may reflect its effects on the myocardial renin-angiotensin system, and suggests that this agent may offer a therapeutic advantage compared with other angiotensin converting enzyme inhibitors.
