There is a paucity of data on acute myocardial infarction (AMI) outcomes for female patients with type 1 diabetes (T1DM) compared with men. The National Inpatient Sample Database was queried from 2011 to 2019 for relevant International Classification of Diseases, Ninth and Tenth Revision procedural and diagnostic codes. Hospitalizations with an admitting diagnosis of non-ST-elevation myocardial infarction or ST-elevation myocardial infarction were compared between male and female patients with T1DM. A multivariate logistic regression adjusting for baseline characteristics and primary diagnosis was performed. A p <0.001 was considered significant. A total of 50,020 hospitalizations for AMI in patients with T1DM were identified, of which 23,980 (47.9%) were women. The baseline characteristics are listed in Table 1. Women experienced similar rates of all-cause and inhospital mortality (5.0% vs 4.7%, p = 0.082). However, after adjusting for baseline characteristics and primary diagnosis, women had higher odds of mortality (adjusted odds ratio [aOR] 1.26, 95% confidence interval [CI] 1.15 to 1.38). Women were less likely to undergo cardiac catheterization (65.7% vs 68.2%; aOR 0.90, 95% CI 0.86 to 0.94) and coronary artery bypass grafting (5.6% vs 6.9%; aOR 0.76, 95% CI 0.70 to 0.82, p <0.001 for both). There was no difference in the use of percutaneous coronary intervention (41.0% vs 41.9%; aOR 1.01, 95% CI 0.97 to 1.05, p = 0.042). The female gender is not protective against AMI in patients with T1DM. Women with T1DM, on average, experience AMI at the same age as men, are less likely to undergo surgical revascularization, and have higher odds of mortality.
