Abstract:
We aimed to compare in-hospital mortality (IHM) of acute myocardial infarction (AMI) between male and females. We assessed the association of sex with IHM after AMI using simple and multivariate cox regression models. Results were presented as crude and adjusted hazard ratios along with their 95% confidence interval (HR; 95% CI). Multivariable Cox regression analysis revealed females had a higher risk of death than males after ST-elevation MI (STEMI) (adjusted HR [95% CI]: 1.64 [1.15-2.36]; p = 0.007). In subgroup analysis by age group, this significantly increased risk was only observed in 50- to 64-year-old females. There were no significant differences between genders after non-STEMI and unspecified MI. Women aged 50 to 64 years had higher IHM after STEMI than men.
