Sex differences in patient and procedural characteristics and early outcomes following cardiac surgery

Area of Science:

• Cardiovascular Surgery
• Surgical Outcomes
• Gender Differences in Medicine

Background:

• Cardiac surgery involves significant risks, and understanding gender-specific outcomes is crucial for optimizing patient care.
• Previous studies suggest potential disparities in treatment and outcomes between male and female patients undergoing cardiovascular procedures.

Purpose of the Study:

• To investigate if women undergoing cardiac surgery experience higher rates of postoperative complications and mortality compared to men.
• To analyze baseline and procedural characteristics that may influence outcomes in female cardiac surgery patients.

Main Methods:

• Retrospective analysis of 4030 adult patients undergoing cardiac surgery (coronary artery bypass grafting and/or aortic valve replacement) between 2007 and 2012.
• Comparison of baseline demographics, surgical details, and postoperative mortality between female and male patient groups.
• Logistic regression analysis to identify independent risk factors for mortality.

Main Results:

• Female patients were older, had higher EuroSCORE risk, and higher BMI.
• In coronary artery bypass grafting (CABG), women received fewer distal anastomoses and arterial grafts were used less frequently.
• While female CABG patients had higher hospital and early mortality, female gender was not an independent risk factor in logistic regression analysis. No gender difference in mortality was observed in the aortic valve replacement (AVR) group.

Conclusions:

• Female gender is not an independent predictor of mortality after cardiac surgery, despite women presenting with higher risk factors.
• Differences in surgical procedures and gender-related treatment variations may significantly impact outcomes.
• Further research is warranted to explore these gender-specific treatment differences and their effect on cardiac surgery outcomes.
