Natural history of dilated cardiomyopathy: from asymptomatic left ventricular dysfunction to heart failure – a subgroup analysis from the Trieste Cardiomyopathy Registry

Abstract

The proportion of asymptomatic patients with DCM at the moment of first evaluation at our center is significant (30%). Among them, those without a previous history of heart failure had a less advanced disease and a trend for a better long-term outcome on optimal medical treatment. Therefore, early diagnosis may offer better long-term quality of life and even better survival. Further studies on larger populations are indicated.
