Outcome with a cardiomyopathy is related to the etiology

In a study of 1230 patients with a cardiomyopathy of various etiologies, the adjusted Kaplan-Meier estimates of survival are related to the underlying cause of cardiomyopathy; only idiopathic cardiomyopathy and cardiomyopathy due to causes for which survival was significantly different from that in patients with idiopathic cardiomyopathy are shown. The best outcome is in those with a peripartum cardiomyopathy, and the worst outcome is in those with an infiltrative cardiomyopathy or that due to HIV infection.
