Vasodilator therapy of dilated cardiomyopathy

Vasoconstriction increases nnpedance to ventricular ejection and impairs the performance of the dilated myopathic heart. Vasodilator drug therapy by reducing vascular resstance, increasng vascular compliance and increasing vascular capacitance improves cardiac function and relieves the signs and symptoms of congestive heart failure. Earlier intervention in an attempt to alter the natural history of cardiomyopathy should be studied.
