BACKGROUND: Emergent myocardial reperfusion via primary percutaneous coronary intervention is optimal care for patients presenting with ST-segment elevation myocardial infarction (STEMI). Delays in such interventions are associated with increases in mortality. With the shift in focus to contact-to-device (C2D) time as a new perfusion metric, this study was designed to examine how sex affects C2D time and mortality in STEMI patients.
METHODS AND RESULTS: Clinical data on male and female STEMI patients were extracted and analyzed from the National Cardiovascular Data Registry from July 1, 2008 to December 31, 2014. A total of 102 515 patients were included in the final analytic cohort. The median C2D time in female patients with STEMI was delayed when compared to male patients (80 [65-97] versus 75 [61-90] minutes; P<0.001). The unadjusted mortality was higher in female patients when compared to male patients with STEMI (4.1% versus 2.0%; P<0.001). For every 5-minute increase in C2D time, the adjusted odds ratio for mortality was 1.04 (95% CI, 1.03-1.06) for female patients with STEMI and 1.07 (95% CI, 1.06-1.09) for male patients (P for sex by C2D interaction=0.003).
CONCLUSIONS: To date, this is the largest analysis of STEMI patients that measures the impact of the new recommended C2D reperfusion metric on in-hospital mortality. Female STEMI patients have longer C2D times and increased mortality. The disparity can be improved and survival can increase in this high-risk patient cohort by decreasing systems issues that cause increased reperfusion times in female STEMI patients.
