Gender differences in patients with atrial fibrillation.

Area of Science:

• Cardiology
• Internal Medicine
• Public Health

Background:

• Atrial fibrillation (AF) is a common arrhythmia with potential for serious complications.
• Previous research suggested gender disparities in AF management and outcomes.
• Understanding these differences is crucial for equitable patient care.

Purpose of the Study:

• To investigate gender-based differences in the presentation, management, and outcomes of patients with atrial fibrillation.
• To compare treatment strategies and clinical results between male and female AF patients.
• To evaluate if observed gender differences align with or contradict prior findings.

Main Methods:

• A post-hoc analysis of an observational study involving 2,742 ambulatory patients with electrocardiography (ECG)-confirmed AF.
• Data collected by 616 cardiologists in Germany from baseline and 12-month follow-up visits.
• Assessment included patient demographics, AF type, quality of life, medication use, and clinical outcomes such as stroke.

Main Results:

• Women with AF were younger on average and more often had paroxysmal AF, while men had permanent AF.
• Quality of life scores were slightly lower in women. Differences in anti-arrhythmic drug use were noted.
• No significant gender differences were found in oral anticoagulation (OAC) use or stroke rates, despite variations in conversion therapies.

Conclusions:

• Current clinical practice shows no substantial gender-based disparities in the management or major outcomes of atrial fibrillation.
• This contrasts with earlier studies suggesting undertreatment of OAC and higher stroke risk in women.
• The findings indicate a more equitable approach to AF care in contemporary cardiology practice.
