Sex differences in postoperative outcomes for infective endocarditis.

PURPOSE OF REVIEW: Infective endocarditis (IE) remains a prevalent and high-risk condition despite advances in cardiac care. Increasing attention has been directed toward sex-based differences in physiological presentation, disease progression, and surgical management. This review synthesizes evidence on sex-specific differences in IE, with an emphasis on diagnosis, risk factors, disease manifestations, medical management, surgical intervention, and postoperative outcomes.

RECENT FINDINGS: While the incidence of IE is more than twice as high in men, women consistently experience worse outcomes. Women present at an older age, with greater comorbidity burden and greater delays in surgical referral. Postoperatively, women are at higher risk of complications - including embolic events, extended ventilation time, and intensive care unit stays - and have significantly higher short-term mortality. Long-term survival is comparable between sexes, suggesting disparities largely influence short-term outcomes.

SUMMARY: Awareness of sex-specific differences in risk factors, clinical presentation, intervention bias, complications, and outcomes of IE is essential for optimizing management and equitable care. Further research into sex-based pathophysiology, comorbidity management, and tailored perioperative strategies is critical to advancing patient-centered treatment and optimizing clinical outcomes.
