Coronary artery surgery outcome differences by sex

Area of Science:

• Cardiology
• Cardiovascular Surgery
• Health Disparities

Background:

• Coronary artery bypass grafting (CABG) is a standard treatment for coronary artery disease.
• Women undergoing CABG face higher mortality, graft failure, and complications than men.
• Existing disparities are linked to age, comorbidities, anatomical differences, and socioeconomic factors.

Purpose of the Study:

• To examine the sex-based outcome disparities in patients undergoing CABG.
• To identify underlying factors contributing to poorer outcomes in women.
• To propose strategies for improving CABG outcomes in women.

Main Methods:

• Review of existing literature and clinical data on CABG outcomes stratified by sex.
• Analysis of patient demographics, risk factors, and surgical characteristics.
• Evaluation of postoperative complications, graft patency, and long-term survival.

Main Results:

• Women exhibit higher operative mortality, long-term mortality, and graft failure rates post-CABG.
• Postoperative complications like stroke and sternal wound infections are more frequent in women.
• Factors contributing to disparities include older age, more comorbidities, smaller graft/artery size, and socioeconomic barriers.

Conclusions:

• Significant sex disparities exist in CABG outcomes, with women facing poorer results.
• Multifactorial issues including biological, socioeconomic, and care-related factors contribute to these differences.
• Future strategies must focus on sex-specific care, clinical trial representation for women, and enhanced secondary prevention.
