Atrial fibrillation (AF) affects men more than women, but this difference diminishes with age. Women with AF, particularly those over 75, face higher risks of stroke and mortality, benefiting most from anticoagulation.

Area of Science:

  • Cardiology
  • Epidemiology
  • Pharmacology

Background:

  • Atrial fibrillation (AF) incidence is higher in men, though this disparity lessens in older populations.
  • Distinct comorbidities are associated with AF in different genders: valvular disease in women and coronary artery disease in men.
  • AF is a significant risk factor for mortality and stroke in both sexes.

Purpose of the Study:

  • To investigate gender-specific differences in atrial fibrillation incidence, risk factors, and outcomes.
  • To evaluate the impact of gender on treatment strategies and efficacy for atrial fibrillation.
  • To highlight the particular risks and benefits of anticoagulation for women with atrial fibrillation.

Main Methods:

  • Retrospective analysis of epidemiological data on atrial fibrillation.

  • Comparative analysis of comorbidities and risk factors stratified by gender.
  • Evaluation of treatment outcomes, including stroke, embolism, mortality, and drug-induced arrhythmias, based on gender.

    • Main Results:

    • While men have a higher initial incidence of AF, the gap narrows with age.
    • Women with AF are more prone to valvular heart disease, whereas men often have underlying coronary artery disease.
    • Women, especially those over 75, exhibit increased risks for embolism and long-term mortality.
    • Women are more susceptible to drug-induced arrhythmias, influencing antiarrhythmic drug selection.
    • Anticoagulation for stroke prevention in chronic AF offers substantial benefits, particularly for women.

    Conclusions:

    • Gender significantly influences atrial fibrillation's epidemiology, associated pathologies, and clinical outcomes.
    • Tailored management strategies considering gender-specific risks and benefits are crucial for atrial fibrillation care.
    • Women with atrial fibrillation, particularly older women, require vigilant monitoring and may gain the most from anticoagulation therapy for stroke prevention.
