Sex differences in cardiac rehabilitation

Area of Science:

• Cardiology
• Rehabilitation Medicine
• Public Health

Background:

• Cardiac rehabilitation programs are crucial for post-cardiac event recovery.
• Understanding sex-based differences in participation and outcomes is vital for equitable care.
• Women are a minority in many cardiac rehabilitation programs.

Purpose of the Study:

• To compare baseline characteristics and outcomes between men and women in a Canadian cardiac rehabilitation program.
• To identify potential sex-based disparities in program participation and effectiveness.

Main Methods:

• A retrospective, observational study design was employed.
• Data were collected from 387 patients (18% women) enrolled between 1995 and 1997.
• A multifactorial, three-month cardiac rehabilitation program including exercise, risk factor modification, education, and psychosocial support was analyzed.

Main Results:

• Women had higher baseline total cholesterol, LDL, and HDL cholesterol levels compared to men.
• Men exhibited higher baseline exercise capacity (METs) and physical activity levels.
• Despite differences in baseline metrics and diagnoses (myocardial infarction vs. bypass grafting), both sexes showed similar improvements in exercise capacity and risk factor profiles post-program.

Conclusions:

• Women are underrepresented in this cardiac rehabilitation cohort.
• Cardiac rehabilitation programs appear equally beneficial for both men and women.
• Further research may explore reasons for lower female participation and tailored interventions.
