[Alcohol and the heart].

S Müller, K Pocher

    Zeitschrift Fur Die Gesamte Innere Medizin Und Ihre Grenzgebiete
    |August 15, 1981

    Summary
    This summary is machine-generated.

    Alcohol acutely impairs heart function by increasing left-ventricular pressure and decreasing stroke volume. Chronic alcohol abuse can cause alcohol cardiomyopathy, a serious heart muscle disease.

    Area of Science:

    • Cardiology
    • Toxicology
    • Physiology

    Context:

    • Alcohol consumption significantly impacts cardiovascular function.
    • Understanding the acute and chronic effects of alcohol on the heart is crucial for clinical practice.

    Purpose:

    • To describe the acute hemodynamic and metabolic effects of alcohol on the myocardium.
    • To define and elaborate on alcohol cardiomyopathy, including its pathogenesis, clinical presentation, and management.

    Summary:

    • Acute alcohol intake increases left-ventricular pressure and decreases stroke volume, indicating impaired systolic function and increased myocardial oxygen demand.
    • Chronic alcohol abuse leads to alcohol cardiomyopathy, characterized by unexplained myocardial and functional disease, often presenting with systolic dysfunction and hypertension.

  • The pathogenesis of alcohol cardiomyopathy is multifactorial, representing a severe stage of alcohol-induced myocardial damage.

    • Impact:

    • Provides a comprehensive overview of alcohol's detrimental effects on the heart.
    • Highlights the importance of recognizing and managing alcohol cardiomyopathy.
    • Informs clinical diagnosis, treatment strategies, and patient prognosis related to alcohol-induced heart disease.
