Sex Differences in Cardiac Transplantation

Area of Science:

• Cardiology
• Transplantation Medicine
• Sex Differences Research

Background:

• Heart transplantation (HT) is a critical treatment for end-stage heart failure.
• Understanding sex-specific factors is crucial for optimizing HT outcomes.
• Women remain underrepresented in HT candidate pools and recipient statistics.

Purpose of the Study:

• To review current evidence on sex differences in heart transplantation.
• To identify disparities in HT access, waitlist management, and post-transplant outcomes.
• To highlight areas for future research in sex-specific HT considerations.

Main Methods:

• Systematic review of contemporary literature on sex differences in HT.
• Analysis of data regarding waitlist demographics, outcomes, and post-transplant complications.
• Synthesis of findings related to candidate selection, donor matching, and referral patterns.

Main Results:

• Women constitute about 25% of HT candidates and recipients.
• Women experience higher waitlist mortality, particularly at higher priority tiers.
• Post-transplant complications and outcomes differ between sexes.

Conclusions:

• Sex-specific factors significantly influence HT candidate selection, waitlist management, and post-transplant results.
• Barriers such as referral issues, implicit bias, and sensitization concerns contribute to sex disparities.
• Further research is needed on sex differences in surveillance, renal outcomes, and patient-reported outcomes to ensure equitable HT allocation.
