title: Chronic alpha-adrenoceptor blockade with trimazosin in congestive heart failure.
abstract: We evaluated chronic adjunctive alpha-1 receptor blockade with trimazosin in congestive heart failure. This agent produced hemodynamic effects consistent with venodilation (reduced left ventricular volume and filling pressure with increased left ventricular ejection fraction), but only during exercise. Resting hemodynamic parameters and exercise duration were not significantly altered by chronic alpha-1 receptor blockade.
