Risk Factors, Use of Revascularization, and Outcomes in Young Adults With ST-Elevation Myocardial Infarction
AMERICAN JOURNAL OF CARDIOLOGY(2024)
Abstract
The incidence of acute myocardial infarction is increasing in younger age groups, with differences in treatment and outcomes based on gender. ST-elevation myocardial infarction (STEMI) in young adults, however, is incompletely understood as most of the current studies were performed in homogenous populations, did not focus on STEMI, and lack direct comparisons with older adults. We performed a retrospective observational study York State with a principal diagnosis of STEMI from 2011 to 2018. There were 58,083 STEMIs with the majority being male (68.2%) and non-Hispanic White (64.8%), with an average age of 63.9 13.9 years. Of these, 8,494 (14.6%) occurred in patients aged <50 years. The proportion of STEMIs in women increased with age, from 19.2% in the <50-year-old age group to 48.9% in the >= 70-year-old age group. Young adults with STEMI had greater prevalence of obesity, current tobacco use, other substance use, and major psychiatric disorders, were more likely to receive revascularization, and had lower 1-year mortality than older age groups. Revascularization was associated with at least a 3 times lower odds ratio of 1-year mortality in all age groups. In conclusion, young adults with STEMI had a unique set of risk factors and co-morbidities and were more likely to undergo revascularization than older age groups. In all age groups, female gender was associated with a higher burden of co-morbidities, decreased use of revascularization, and increased 1-year mortality. (c) 2024 Elsevier Inc.
