Zheng H, et al. - Researchers evaluated sex-based disparities in rehospitalization for heart failure (HF) and myocardial infarction (MI) within 1 year from discharge in 7,597 consecutive ST-elevation myocardial infarction (STEMI) patients (13.8% women; N=1,045) who had primary percutaneous coronary intervention (pPCI) from January 2007 to December 2013. Once the disparities in baseline characteristics and treatment were adjusted, reduction in the sex differences pertaining to the risk of rehospitalization for HF were noted. Sex differences persisted for MI, with greater disparity among patients aged ≥ 60 years vs those aged < 60 years. Among the sexes, a similar adjusted risk of 1-year rehospitalization for HF was found, but a higher adjusted risk of 1-year rehospitalization for MI was detected in women—especially older women in a setting of universal access to pPCI.
