Abstract
In the past, coronary artery bypass grafting was the treatment of choice for patients with symptomatic multi vessel coronary artery disease, but in recent years per cutaneous transluminal coronary angioplasty (PTCA) accepted as an alternative approach to revascularization. To assess the initial success and in hospital results of coronary angioplasty of more than one lesion per procedure in patients with multi vessel coronary artery disease, a retrospective analysis of patients who underwent selective coronary angioplasty at Imam Khomeini medical center from 1994-1997 were peformed. From 1994 to 1997 per cutaneous transluminal coronary angioplasty (PTCA) were done in 257 patients, that 201 (78.2 percent) were male and their age range 23-73 years. The numbers of patients with multi vessel coronary artery disease were 98 (38.13 percent), that complete revascularization (PTCA of more than one lesion per procedure) underwent in 34 (13.58 percent) of them (27 men, 7 women, age: mean±SD 48±9.8 range 30-70). A total of 71 lesions were tried, that 22 (31 percent) were type A, 45 (63.4 percent) were type B, and 4 (5.6 percent) were type C. Among patients 21 (61.8 percent) had unstable angina and 13 (38.2 percent) had stable angina. Procedures were successful in 68 (95.8 percent) of lesions and 31 (91.2 percent) patients were discharged fro procedural complications included 3 (8.8 percent) non-Q wave myocardial infarction and no mortality. Without any complication, (success defined as residual stenosis <50 percent). As a conclusion, in selected patients with multi vessel coronary artery disease PTCA of more than one lesion per-procedure is effective and safe.

Abstract
Background: Cardiovascular diseases alone have become the leading cause of death worldwide. One of the treatment methods cardiovascular disease is angioplasty. This study aimed to investigate the clinical results after coronary artery angioplasty, based on the incidence of major cardiovascular events with emphasis on stent types.
Methods: In this retrospective cross-sectional study, the prevalence of risk factors (age, history of previous illness and previous surgery) was assessed by using a case file for patients undergoing coronary angioplasty and stent placement during the years 2006 to 2016 and found during the follow-up. The place of the study was the Imam Ali Hospital's educational center affiliated to Kermanshah University of Medical Sciences, Iran, from July to September 2017.
Results: In this study, 1188 patients undergone to stent containing 909 non-drug stents, 504 sirolimus-eluting stents and 316 paclitaxel-eluting stents. Patients were followed-up one to five years. During follow-up, 98 patients involved major cardiovascular events, 6 cases involved with death and 91 patients involved with myocardial infarction. 1729 of patients undergone angioplasty and during follow-up, 91 patients had stent restenosis. In this study stent restenosis showed the highest correlation with the incidence of major cardiovascular events. With a view to stent type in lesions with stent restenosis, 61.7% was in non-drug stent, 23.5% was in paclitaxel-eluting stent and 14.8% was in sirolimus-eluting stent. This study also showed that despite the superiority of sirolimus-stained stents, there was no difference between paclitaxel-stained stents and non-drug stents in clinical outcomes and restenosis.
Conclusion: The results showed that the syringes impregnated with sirolimus have better quality. Also, stents that have a smaller diameter or need dilatation in the procedure have a worse prognosis and cause more complications in the patient.
