Chronic alcoholism can cause congestive heart failure with high cardiac output. Alcohol withdrawal, rest, and nutrition resolved symptoms and heart enlargement without thiamine supplementation.

Area of Science:

  • Cardiology
  • Internal Medicine
  • Toxicology

Background:

  • Chronic alcoholism is a significant risk factor for cardiovascular disease.
  • Alcohol-induced cardiomyopathy can manifest with heart failure symptoms.
  • Hyperdynamic circulation is sometimes observed in advanced alcoholic heart disease.

Observation:

  • A patient with chronic alcoholism presented with new-onset congestive heart failure.
  • Clinical signs indicated a hyperdynamic state with a low arteriovenous oxygen content difference, suggesting high cardiac output.
  • Cardiomegaly was evident on initial examination.

Findings:

  • The patient's congestive heart failure and hyperdynamic features resolved within 10 days of alcohol withdrawal.
  • Rest and balanced nutritional support were key components of the treatment.

  • No thiamine supplementation was needed for recovery.

    • Implications:

    • This case highlights the potential reversibility of alcohol-induced heart failure with prompt cessation of alcohol consumption.
    • It suggests that not all cases of alcoholic cardiomyopathy require thiamine, challenging some traditional treatment paradigms.
    • Early intervention focusing on alcohol abstinence and supportive care can lead to significant clinical improvement and resolution of cardiomegaly.
