Multiple Choice

In a patient with heart failure and reduced ejection fraction due to chronic alcohol use, which histology would you most likely find?

Chronic alcohol exposure damages cardiac myocytes over time, leading to a dilated cardiomyopathy pattern with remodeling of the ventricle. The histology you’d expect shows myocyte hypertrophy with interstitial (fibrous) fibrosis. The hypertrophy reflects the heart’s attempt to compensate for chronic injury, while the fibrosis represents replacement and scarring that stiffens the myocardium and contributes to reduced ejection fraction and heart failure. Eosinophilic infiltrates would suggest eosinophilic myocarditis; necrosis with neutrophils is typical of an acute myocardial infarction; chronic inflammation with plasma cells points to a chronic infectious or autoimmune process—patterns not characteristic of alcoholic cardiomyopathy.
