Gender-related disparities of Percutaneous Coronary interventions in ST- elevation myocardial infarction: a retrospective chart review of 500 patients.

Door to balloon (DTB) time of primary percutaneous coronary intervention (PCI) in ST-elevation myocardial infarction (STEMI) is a predictive indicator of outcomes and mortality. Traditional gender-related differences that existed in the provision of DTB in STEMI had been allegedly improving until recent controversial data showed re-emergence of longer DTB in females. The objective of our study was to compare circadian disparities in PCI for STEMI according to gender in our institution. We compared DTB and symptom to balloon (STB) as well as mortality outcomes in a registry of 514 patients. We studied 117 females and 397 males. Baseline characteristics and cardiovascular risk factors were similar among both populations. Men used more self-transportation (51% vs 38%) compared to women. Both had similar DTB median times; males 63 (47-79) min and females 61 (44-76) min. In addition, STB median times were also similar; males: 155 (116-264) min; and females 165 (115-261) min. Mortality outcomes at 1 month were comparable at 3% in males vs 0.9% in females (p=0.164). In a review of a tertiary care center in New York; we observed no gender differences in DTB and STB; endorsing the role of EMS transportation in eliminating disparities.
