In-hospital Results of Primary Stenting in Acute Myocardial Infarction

High reocclusion and restenosis rates with pri ınaı·y angioplasty (PTCA) had evoked the idea of primary stenting in acute ın yocard i al infaretion (AMI). In this study we evaluated the efficacy and safety of priınary stenting in AMI. Study group consisted of 82 patients who underwent priınary PTCA between October 1995 and.October 1998 and had subopti ınal or fai led outcome. Acute occlusion or an threatened occlusion or a 2:30% residual narrowing after PTCA was an indication for priınaı·y stenting. 85.3% of the cases were ınale and the mean age was 53.2 ± 7.78. Chest pain to admission time was 197.5 ± 44.9 min, admission to femora l puncture time was 23.5 ± 6. 1 1, admission to reperfusion time was 45.3 ± 29.1 min and duration of stay in catheheterization laboratory was 52.2 ± 25.4 min. Two stents were deployed in 2 cases and one stent in the remaining patients. High press u re (15.5 ± 3.01 mmHg) was u sed for stent deployment in all cases. Reference vessel size was 3.12 ± 0.21 mm, gained vessel size was 3.04 ± 0.22 mm and the residual stenosis was 8.3 ± 4.3 %. TIMI 3 flow was achieved in 81 cases. One patient died who underwent emergency CABG operation due to acute instent thrombosis. Recurrent ischemia or rei nfarction was not recorded during the inhospital period. Two cases required blood transfusion due to the groin hemotoma at the femoral access site. At the predischarge catheterization no restenosis or reocclus ion was recorded. Left ventricular mean ejection fraction was 57.2 ± 9.9 %. In conclusion, primary stenting is a safe procedure with optimal angiographic outcome in AMI. Outcome of primary PTCA was improved and hospital stay period was decreased due to the lower reocclusion, reinfarction and reccurrent ischemia rates.
