Does a history of breast cancer affect in-hospital mortality and complications in adult women hospitalized with STEMI?
Contrary to expected increased risk, breast cancer survivors hospitalized with STEMI had lower in-hospital mortality and complications compared to those without breast cancer.
Breast cancer is the most common malignancy among women. While advances in detection and treatment have improved survival, breast cancer survivors face an increased risk of cardiovascular disease. However, limited data exist on cardiac outcomes after ST-elevation myocardial infarction (STEMI) in this population. This retrospective cohort study analyzed the National Inpatient Sample (NIS) database (2016–2021). Adult women hospitalized with STEMI were categorized as breast cancer survivors or without a history of breast cancer. The primary outcome was in-hospital mortality, with multivariable logistic regression used to adjust for confounders. A total of 369,070 adult females were included (breast cancer survivors, n = 13,890; without breast cancer, n = 355,180). Breast cancer survivors were older with more cardiovascular comorbidities. After adjustment, breast cancer survivors had lower odds of in-hospital mortality (adjusted odds ratio aOR 0.82, 95% CI 0.72–0.93), cardiogenic shock (aOR 0.88, 95% CI 0.77–0.99), and acute kidney injury (aOR 0.85, 95% CI 0.76–0.95). Breast cancer survivors hospitalized for STEMI had lower in-hospital mortality and complications, compared with those without breast cancer. These hypothesis-generating findings suggest that advances in oncology and cardiovascular care may contribute to improved outcomes.
