Women and patients aged ≥75 years with acute myocardial infarction had a lower receipt of invasive cardiac procedures compared to men and younger patients, though gaps narrowed from 2005 to 2018.

Are there age and sex differences and temporal trends in the use of invasive and noninvasive procedures in patients hospitalized with acute myocardial infarction?
Despite narrowing gaps in recent years, women and older patients with acute myocardial infarction remain less likely to receive invasive cardiac procedures.
Background Few studies have examined age and sex differences in the receipt of cardiac diagnostic and interventional procedures in patients hospitalized with acute myocardial infarction and trends in these possible differences during recent years. Methods and Results Data from patients hospitalized with a first acute myocardial infarction at the major medical centers in the Worcester, Massachusetts, metropolitan area were utilized for this study. Logistic regression analysis was used to examine age (<55, 55-64, 65-74, and ≥75 years) and sex differences in the receipt of echocardiography, exercise stress testing, coronary angiography, percutaneous coronary interventions, and coronary artery bypass graft surgery, and trends in the use of those procedures during patients' acute hospitalization, between 2005 and 2018, while adjusting for important confounding factors. The study population consisted of 1681 men and 1154 women with an initial acute myocardial infarction who were hospitalized on an approximate biennial basis between 2005 and 2018. A smaller proportion of women underwent cardiac catheterization, percutaneous coronary intervention, and coronary artery bypass graft surgery, while there were no sex differences in the receipt of echocardiography and exercise stress testing. Patients aged ≥75 years were less likely to undergo cardiac catheterization, percutaneous coronary intervention, and coronary artery bypass graft surgery, but were more likely to receive echocardiography compared with younger patients. Between 2005 and 2018, the use of echocardiography and coronary artery bypass graft surgery nonsignificantly increased among all age groups and both sexes, while the use of cardiac catheterization and percutaneous coronary intervention increased nonsignificantly faster in women and older patients. Conclusions We observed a continued lower receipt of invasive cardiac procedures in women and patients aged ≥75 years with acute myocardial infarction, but age and sex gaps associated with these procedures have narrowed during recent years.
Tran et al. (Wed,) conducted a observational in acute myocardial infarction (n=2,835). Female sex and older age (≥75 years) vs. Male sex and younger age was evaluated on Receipt of cardiac diagnostic and interventional procedures. Women and patients aged ≥75 years with acute myocardial infarction had a lower receipt of invasive cardiac procedures compared to men and younger patients, though gaps narrowed from 2005 to 2018.
