Abstract
Background: Limited studies have demonstrated sex differences in the clinical outcomes and quality of care among elderly patients hospitalized with acute myocardial infarction (AMI).
Methods and results: Using nationwide cardiovascular registry data collected in Japan between 2012 and 2019, we enrolled patients aged ≥45 years. The 30-day and all in-hospital mortality rates, as well as process-of-care measures, were assessed, and mixed-effects logistic regression analysis was performed. A total 254,608 patients were included and stratified into 3 age groups: middle-aged, old and oldest old. The 30-day mortality rates for females and males were as follows: 3.0% vs. 2.7%, with an adjusted odds ratio (OR) of 1.17 (95% confidence interval (CI): 1.01-1.36, P=0.030) in middle-aged patients; 7.2% vs. 5.8%, with an OR of 1.14 (95% CI: 1.09-1.21, P<0.001) in old patients; and 19.6% vs. 15.5% with an OR of 1.17 (95% CI: 1.09-1.26, P<0.001) in the oldest old patients. Moreover, significantly higher numbers of female AMI patients across all age groups died in hospital, as well as having fewer invasive procedures and cardiovascular prescriptions, compared with their male counterparts.
Conclusions: This nationwide cohort study revealed that female middle-aged and elderly patients experienced suboptimal quality of care and poorer in-hospital outcomes following AMI, compared with their male counterparts, highlighting the need for more effective management in consideration of sex-specific factors.
