Short and long-term survival after primary percutaneous coronary intervention in young patients with ST-elevation myocardial infarction

Abstract The long-term prognosis of patients with ST-elevation myocardial infarction (STEMI) aged 45years or younger and differences according to gender have not been well characterized. Methods We included 16,685 consecutive STEMI patients from 2003 to 2012 (67,992 patient-years follow-up) from the Eastern Danish Heart Registry and the Swedish Coronary Angiography and Angioplasty Registry who were treated with primary percutaneous coronary intervention (PCI). Results We identified 1026 (6.2%) patients up to 45years of age (mean age: 40.7 vs. 66.3years, P P P P P P P =0.59) or long-term (HR=0.62, CI: 0.33–1.91, P =0.59) mortality between women and men in the young group (HR=0.79, CI: 0.21–1.80, P =0.39). Conclusions STEMI patients, aged 45years or younger, have an excellent prognosis after treatment with primary PCI. Long-term annual survival is more than 99% in these patients. Young women with STEMI do not have a worse long-term prognosis than young men with STEMI.
