Abstract

Dilated cardiomyopathy is characterized by ventricular dilation and contractile dysfunction in the absence of abnormal charging conditions, with an annual incidence of 6 to 7 cases per 100.000 individuals. Its main risk factors include genetic predisposition, myocarditis, chronic alcohol consumption, and metabolic disorders. Myocarditis, an inflammatory disease of the myocardium, is an important cause of dilated cardiomyopathy and has as risk factors viral infections, toxic agents, and genetic predisposition. Diagnosis is preferably established by endomyocardial biopsy, although imaging modalities and serum markers are also useful. Alcohol consumption combined with energy drinks represents a risk for both conditions, due to myocardial toxicity, transient increase in contractility, and subsequent cardiac dysfunction. This report describes the case of a 38-year-old man who developed infectious symptoms followed by severe cardiac dysfunction, with ventricular dilation, reduced ejection fraction, atrial fibrillation, and elevated B-type natriuretic peptide levels. During follow-up, cardiac magnetic resonance imaging revealed global systolic dysfunction and interstitial fibrosis, corroborating the diagnosis of dilated cardiomyopathy. The favorable outcome, with improvement of the ejection fraction, underscores the importance of early diagnosis, structural and functional cardiac monitoring, and appropriate management to prevent disease progression and future complications.
