Gender differences in clinical outcome after coronary stenting

Area of Science:

• Cardiology
• Interventional Cardiology
• Gender-Specific Medicine

Background:

• Conflicting data exists on gender differences in outcomes after invasive coronary interventions.
• Some studies indicate female gender predicts higher mortality and complications post-procedure.
• No prior evaluation of gender differences in coronary stenting outcomes had been conducted in the region.

Purpose of the Study:

• To determine the impact of gender on clinical outcomes for men and women undergoing coronary stenting.
• To compare the safety and efficacy of coronary stenting between genders.
• To identify potential factors contributing to outcome disparities.

Main Methods:

• Retrospective review of medical records for 205 men and 122 women undergoing coronary stenting.
• Analysis of clinical characteristics, procedural data, and immediate complications.
• Evaluation of six-month post-procedure clinical events through follow-up assessments.
• Statistical comparison using Student's t-test, Mann-Whitney-Wilcoxon, chi-square, and Fisher's exact tests.

Main Results:

• Procedural success and early complication rates were similar between genders.
• Men exhibited significantly higher rates of re-hospitalization and re-intervention within six months post-procedure.
• Lower ejection fraction, history of myocardial infarction, and smoking in men may correlate with increased complications.

Conclusions:

• Findings suggest clinical factors, rather than gender itself, may be more strongly associated with outcome differences in patients undergoing coronary stenting.
• A larger prospective study is warranted to further investigate these gender-related outcome disparities.
• The study highlights the need to consider individual clinical profiles in managing patients post-coronary stenting.
