Abstract
Seven patients with severe heart failure resistant to conventional treatment with digoxin and diuretics were given trimazosin, a new mixed arterial and venous vasodilator. There was a mean 31% fall in left ventricular filling pressure (P > 0.005) and a mean 25% rise in cardiac index (P> 0.05). One patient failed to respond. In three patients these haemodynamic changes resulted in excellent clinical and radiological improvement which was maintained for months. No side-effects were found.
Oral trimazosin is a long-acting effective mixed vasodilator which improves left ventricular function in patients with chronic resistant left ventricular failure.
