Gender disparity in the use of drug‐eluting stents during percutaneous coronary intervention for acute myocardial infarction. Issue 2 (19th March 2015) - Iyanoye, Adeyemi
Abstract : Objective: We examined gender disparity in the use of drug‐eluting stents (DES) versus bare metal stents (BMS) during percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI), and gender disparity in all‐cause mortality after coronary stent implantation for AMI. Background: Gender disparities in AMI managements have been well documented, but it is unclear whether these disparities are seen in the type of coronary stent implantation for AMI and outcomes. Methods: Hospital discharge data from January 1, 2003 through December 31, 2010 in New Jersey from the Myocardial Infarction Data Acquisition System were used to identify 40, 215 patients (12, 878 women and 27, 337 men) with coronary stent implantation for AMI. The in‐hospital, short term (30 days) and long term (1 and 5 year) all‐cause mortality rates, unadjusted and adjusted for demographics and comorbidities, were determined. Results: Women were older than men and had a higher prevalence of co‐morbidities. Men had higher prevalence of prior coronary revascularizations. After adjustment for co‐morbidities, there was no significant gender difference in the use of DES versus BMS for AMI, except in 2003 and 2006 where women were found to be more likely to receive a DES versus a BMS. After adjustment, women had higher odds of in‐hospital deaths but no difference in short and long‐term all‐cause mortality rates. Conclusions: There was no significant gender difference in the proportion of DES implantation versus BMS for AMI in contemporary years. Women treated with either BMS or DES for AMI had higher in‐hospital death than men. © 2015 Wiley Periodicals, Inc.
