EARLY OUTCOMES FOLLOWING 797 CORONARY STENT PROCEDURES

Abstract

underwent coronary stent implantation in our center. Methods: Armed Forces Institute of Cardiology coronary stents database was used to analyse retrospectively the procedural results, deaths, non-Q and Q wave myocardial infarction (MI) following 797 PTCA procedures in 715 patients during August 2002 - July 2003. Results: 1064 stents were deployed in 797 coronary artery lesions (Type B 59%, Type C 32% and Type A 9%) in 715 patients (87% males). Patients with single vessel coronary artery disease (SVCAD) were 44 %, double vessel coronary artery disease (DVCAD) 38 % and triple vessel coronary artery disease (TVCAD) 18%. Direct stenting was done in 734(69%) cases. Indications for stent implantation were 70% denovo, 12 % acute coronary syndrome (ACS), 8% total occlusion, 4% acute dissection, 3 % grafts, 2 % restenosis, and 0.8% subacute thrombosis (SAT). Over all procedural success was obtained in 786 (98.6 %) cases. In-hospital clinical events include 6 deaths (0.8 %), 12 MI (1.7 %), 8 SAT (1.1 %) and bleeding complications in 13(1.8%) cases. Conclusions: In our series, stent implantation is a safe and effective method of coronary revascularization with a low in-hospital morbidity and mortality even in diabetics, multivessel disease and in patients with acute coronary syndrome. Our data shows direct stenting is a preferable method in majority of cases with high primary success and low complication rate in the hands of experts.
