[Epidemiological observations on survival in the first year after acute ST-elevation myocardial infarction (STEMI) treated by primary angioplasty].

Le résumé fourni par la source

Conditional analysis of survival factors after acute myocardial infarction is important in care practice. We analyzed the survival and occurrence of coronary ischemic events during the first year after the episode of acute myocardial infarction with ST segment elevation (STEMI). We prospectively evaluated at one month and one year the patients with STEMI assisted in November 2008 - February 2010 at Heart Institute "Niculae Stăncioiu" with primary coronary angioplasty (ACP) performed during the first 12 hours of the onset of pain. We analyzed statistically survival and occurrence of ischemic events. Survival rate was 95.6% (CI95%: 92.7 to 97.3) at one month and 92.1% (CI95%: 87.8 to 94.2) ate one year after STEMI. Survival was significantly reduced in anterior STEMI (83.4%), history of ischemic heart disease (83.4%), stroke (81.2%), females (81.8%) and ischemia exceeding > 6 hours (83.6%). The rate of ischemic events avoidance was 96.5% (CI95%: 0.938 to 0.980) at one month and 81.7% (CI95%: 76.7 to 85.6) at one year after STEMI. The ischemic events, as evaluated through avoidance rate of phenomena, were significantly more frequent in females (69.9%), dyslipidemic (72.9%), hypertensive (73.7%) patients, having history of ischemic heart disease (72.4%) and total ischemia time longer than 6 hours (70%). Evolution of patients with STEMI after ACP is significantly better in patients with non-anterior location, males, without history of coronary disease, stroke, hypertension, dyslipidemia, ischemic time > 6 hours.
