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.
