Background: Readmission following hospitalization for acute myocardial infarction (AMI) significantly contributes to preventable morbidity and healthcare costs. Outcomes following AMI vary by sex, but the relationship of sex to readmissions warrants further exploration.
Methods: Using the 2013 Nationwide Readmissions Database, an all-payer database including hospitalizations from 21 US states, we identified patients with a principal discharge diagnosis of AMI and stratified all-cause 30-day readmissions by sex and age.
Results: Of the 214,824 AMI patients, 43.9% were 18-64 years of age, 56.1% were ≥65 years, and 28.1% and 44.8% were female, respectively. For patients 18-64 years of age, the 30-day readmission rate was 13.8% for women and 10.4% for men (p<0.001). For those ≥65 years of age, the readmission rate was 17.8% for women and 16.0% for men (p<0.001). After adjustment for comorbidities, women with AMI had significantly higher risk of readmission, particularly younger women (OR 1.21, 95% CI 1.06-1.39 for ages 18-44; OR 1.13, 95% CI 1.07-1.18 for ages 45-64; OR 1.13, 95% CI 1.07-1.19 for ages 65-74, interaction p<0.001). Men more frequently had invasive cardiac procedures during the index hospitalization (p<0.001). Common readmission diagnoses were AMI, other ischemic heart disease and heart failure.
Conclusions: Women, particularly younger women, are at higher risk of short-term readmission after treatment for AMI. Sex-specific strategies to reduce readmissions after AMI may be warranted.
