All-cause hospitalization rates within 1 year of discharge were 34.8% for women compared with 23% for men. Most hospitalizations for women were coronary-related.
Women with a myocardial infarction with nonobstructive coronary arteries (MINOCA) had lower rates of rehospitalization than women who experienced myocardial infarction with obstructive coronary artery disease (MI-CAD).
There was a more significant sex disparity between women and men for noncardiac hospitalizations compared with all other hospitalizations (incidence rate, 145.8 [women] vs 69.6 [men] per 1000 person-years).
"We were surprised to see the significance of sex difference in 1-year outcomes despite adjusting for over 30 variables, variables that often hold significant impact, such as belonging in the self-reported non-Hispanic Black population and lower socioeconomic status, [and] scores on health status questionnaires," Mitsuaki Sawano, MD, PhD, of the Yale School of Medicine, New Haven, Connecticut, told theheart.org | Medscape Cardiology. "Our findings indicate that women may indeed be at higher risk for 1-year hospitalizations."
Comprehensive data capturing healthcare utilization in young patients with AMI is lacking in the United States, Sawano said. "That is exactly why the VIRGO (Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients) study started more than decade ago."
"Since there is no indication that much has changed in the care provided to young patients over the last decade, we think the data from VIRGO remains relevant to this day," he added.
