Abstract 15362: Young Hispanic Women Experience Higher In-Hospital Mortality Following an Acute Myocardial Infarction
Background: Although mortality rates for acute myocardial infarction (AMI) have declined for men and women, prior studies have reported a gender gap in mortality, such that younger women were most likely to die after an AMI. We sought to explore the impact of race and ethnicity on the gender gap in AMI mortality for young women in a contemporary patient cohort.
Methods: Using data from the 2009-2010 Healthcare Cost and Utilization Project, we constructed hierarchical logistic regression models to examine trends in AMI hospitalizations and in-hospital mortality by gender, age (<65 and ≥65), and race/ethnicity (White, Black, and Hispanic).
Results: Analyses were derived from 207,263 AMI hospitalizations with available race/ethnicity data. There were a total of 9,926 AMI hospitalizations for Black women and 5,482 for Hispanic women. Both Black and Hispanic women were significantly younger at time of index hospitalization for AMI as compared with their white counterparts [mean age (SD) 65.9 (14.2) and 68.6 (14.2) as compared with 72.9 (14.2) for white women, p<0.001]. After adjusting for clinical and demographic characteristics, young Hispanic women <65 experienced higher in-hospital mortality as compared with white men, Odds Ratio (95% CI) of 1.5 (1.2, 1.9). This pattern was not observed for older Hispanic women or Black women (figure).
Conclusion: Using a large, contemporary sample of inpatients, we found significant racial/ethnic and gender disparities in AMI hospitalizations and mortality. Our study suggests that young Hispanic women experience higher in-hospital mortality. Future studies are necessary to explore determinants of these significant racial/ethnic and gender disparities in outcomes for AMI.
