ABSTRACT
The current definition of dilated cardiomyopathy (DCM) is relatively simple; namely, a heart muscle disease characterized by left ventricular (LV) or biventricular dilation and systolic dysfunction in the absence of either pressure or volume overload or coronary artery disease sufficient to explain the dysfunction.1 In the last decades, the prognosis of patients with DCM has improved significantly with survival free from death and heart transplantation rising to more than 80% at 8-year follow-up.2 This improvement in outcomes reflects the implementation of pharmacological and non-pharmacological therapeutic strategies, earlier diagnosis due to familial and sport-related screening, and individualized long-term follow-up with continuous restratification of risk.
