Abstract

The aim of the present study was to assess the early clinical outcome following primary coronary angioplasty in elderly patients (aged > or = 75 years) compared to younger patients (< 75 years). The study population included 655 consecutive patients (mean age 61.5 +/- 12.4 years) with acute ST-elevation myocardial infarction (MI) who underwent primary percutaneous coronary intervention (PCI) within 12 hours of symptom onset. Elderly patients accounted for 14.5% (96 of 655) of all patients. Primary PCI was performed using a balloon and/or coronary stent as well as glycoprotein IIb/IIIa inhibitors. The primary endpoint was the in-hospital incidence of major adverse cardiac events (including death, stroke, reinfarction, target vessel revascularization and new onset of heart failure). Elderly patients were more frequently female (48 vs 20%, p < 0.001) and had more comorbid disease (prior stroke 7.2 vs 2.5%, p < 0.05) and more extensive cardiovascular disease (previous acute MI 13.5 vs 5.5%, p < 0.05; multivessel disease 71.8 vs 44.6%, p < 0.0005) and a significantly lower ejection fraction (48 vs 50%, p < 0.05). Despite a similar rate of TIMI 0-1 flow at presentation (69 vs 74%, p = NS), a similar use of stents (84 vs 86%, p = 0.3)...Continue Reading
