Alcoholic cardiomyopathy

Last edited: 4/15/2026

Overview

Alcoholic cardiomyopathy is a condition characterized by myocardial damage due to chronic alcohol consumption, leading to progressive left ventricular dysfunction and heart failure 1.

Diagnosis

  • Clinical history: Significant alcohol use over time 1.
  • Echocardiography: Evidence of left ventricular systolic dysfunction (e.g., reduced ejection fraction) 1.
  • Electrocardiogram (ECG): May show nonspecific changes like arrhythmias or conduction abnormalities 1.
  • Laboratory tests: Elevated B-type natriuretic peptide (BNP) or N-terminal pro-BNP levels 1.
  • Cardiac MRI: Can confirm myocardial damage and assess fibrosis 1.

    • Management

  • Abstinence from alcohol: Essential for halting disease progression 1.
  • Heart failure medications:
    • - ACE inhibitors: Recommended for reducing morbidity and mortality 1. - Beta-blockers: Improve survival and reduce hospitalizations 1. - Diuretics: For managing fluid overload 1. - ARNI (Angiotensin Receptor-Neprilysin Inhibitors): Consider as an alternative to ACE inhibitors in appropriate patients 1.
  • Lifestyle modifications: Nutritional support, smoking cessation, and management of comorbidities 1.

    • Special Populations

  • Elderly: Management focuses on symptom relief and minimizing side effects due to polypharmacy risks 1.

    • Key Recommendations

  • Achieve and maintain abstinence from alcohol to halt disease progression and potentially reverse left ventricular dysfunction (Evidence: Strong 1).
  • Initiate standard heart failure therapy including ACE inhibitors, beta-blockers, and diuretics to manage symptoms and improve outcomes (Evidence: Strong 1).
  • Monitor and manage comorbidities such as hypertension and diabetes to optimize overall cardiac function (Evidence: Moderate 1).
