Meteorin-like/Meteorin-β protects heart against cardiac dysfunction.

The Journal of experimental medicine·2021

Women exhibit greater susceptibility to alcohol-induced heart damage compared to men. Despite lower ethanol consumption, women develop alcoholic cardiomyopathy at similar rates, indicating a higher female propensity to cardiac injury from alcohol.

Area of Science:

  • Cardiology
  • Toxicology
  • Gender Medicine

Background:

  • Cardiomyopathies display gender-related differences in incidence, presentation, and evolution.
  • Women and men exhibit distinct responses to cardiac insults and myocardial adaptation.
  • Alcohol-induced heart disease shows sex-specific differences in metabolism and pathophysiology.

Purpose of the Study:

  • To investigate gender-related differences in alcohol-induced cardiomyopathy.
  • To compare female and male sensitivity to ethanol's cardiotoxic effects.
  • To elucidate the pathophysiologic mechanisms underlying higher female susceptibility.

Main Methods:

  • Review of existing literature on gender differences in cardiomyopathy.
  • Analysis of preclinical studies on ethanol-induced ventricular dysfunction in both sexes.

  • Comparison of prevalence and consumption data for overt alcoholic cardiomyopathy between men and women.

    • Main Results:

    • Women demonstrate increased sensitivity to the cardiotoxic effects of ethanol compared to men in preclinical models.
    • In overt alcoholic cardiomyopathy, prevalence is similar between genders despite significantly lower ethanol consumption in women.
    • Distinct alcohol metabolism and pathophysiologic mechanisms contribute to greater female cardiac damage.

    Conclusions:

    • Women possess a greater propensity for alcohol-induced cardiac damage.
    • Sex-based differences in response to ethanol necessitate tailored clinical considerations.
    • Further research into sex-specific mechanisms of alcohol cardiotoxicity is warranted.
