title: [Therapy of dilated cardiomyopathies with and without inflammation].
abstract: Diagnosis of inflammatory dilated cardiomyopathy relies on the histological and immunohistological examination of endomyocardial biopsies. Only with the demonstration of the etiological agents in the myocardium specific therapy can be attempted. Whereas the spontaneous course of endemic myocarditis with little hemodynamic impairment is fair, the prognosis of symptomatic myocarditis and dilated cardiomyopathy is poor, with complete restitution in 35% and a 10-year survival rate of 30%. Restriction of physical activity is a validated form of therapy with normalization of the heart size in 40 to 60%. Symptomatic medical therapy consists of digitalis, diuretics, ACE-inhibitors and vasodilators and betablocker therapy, where a reduction of mortality was demonstrated in clinical (sub)studies up to 60%. Specific forms of therapy in inflammatory cardiomyopathy rely on the demonstration or lack of viral persistence or signs of autoreactivity in the myocardial tissue. Immunosuppressive therapy in autoimmune forms improved cardiac function in up to 60% of the patients in controlled trials, when compared to controls (40%). The double-blind randomized myocarditis treatment trial, which unfortunately did not distinguish viral from autoimmune myocarditis could not demonstrate such a benefit, however. Depending on the etiology of the disease, immunomodulation with immunoglobulins or interferon or antiviral therapy with hyperimmunoglobulins are presently tested in clinical treatment trials (ESETCID) in patients with enterovirus-positive or cytomegalovirus-positive and adenovirus-positive chronic myocarditis. Specific therapies are aimed to avoid the progression of the disease which may ultimately lead to heart failure with a cardiac assist device or heart transplantation as ultimate therapeutic option.
