Share:

Overview:

Cardiomyopathy of mixed etiology, that causes 4 chamber dilation and eccentric hypertrophy of the heart.

Cause:

– Chronic alcoholism
– Metabolic abnormalities
– End stage viral infection
– Pregnancy can exacerbate

Morphology:

– 4 chamber dilation
– Eccentric hypertrophy
– Interstitial fibrosis

Diagnosis:

Clinical Findings:
– Systolic dysfunction
– Left ventricular failure symptoms (fatigue, weakness, exercise intolerance, dyspnea)
– And/or right ventricular heart failure (edema, hepatomegaly, increased JVP)
– Arrhythmia
– Thromboembolism

Echocardiogram Findings:
– Hyopcontractility

Treatment:

– Therapy for cardiac failure
– Antiarrhythmics
– Anticoagulation
