Therapeutic alternatives in dilated cardiomyopathy--a review of current options

In addition to the underlying pathophysiological processes that cause myocarditis and dilated cardiomyopathy, structural, biochemical, neurohormonal and haemodynamic influences and interrelations promote progression of the heart failure syndrome. Independent of their symptomatic benefits, diuretics, digitalis, ACE inhibitors, PDE inhibitors and dopamine agonists exert specific influences on factors that retard or accelerate progression of congestive heart failure (CHF). Important factors that indicate or promote progression of CHF are discussed here, with special emphasis on therapeutic options. Interference with baroreceptor function (digitalis, ACE inhibitors), the RAA system (ACE inhibitors), the sympathetic nerve system (dopamine agonists, ACE inhibitors, digitalis) can potentially retard progression of CHF, while other therapeutic options, such as PDE inhibitors and diuretics, might accelerate progression of left ventricular dysfunction and CHF.
