Abstract: 
Background- Stent implantation has emerged as an effective method of treatment for ‎multi vessel coronary disease and has reduced the need for coronary artery bypass ‎graft surgery in many of these cases‏.‏ Methods- From April 1995 to December 2001, 221 candidates for coronary ‎intervention with multi-vessel disease were entered in this study. 212 patients had ‎two-vessel and 9 patients had three-vessel involvement. They were divided into three ‎groups: A (only PTCA), B (PTCA/Stent) and C (Direct Stenting). Age, sex, involved ‎vessels, stent brand, immediate and long -term failure rates and complications were ‎assessed‏.‏
Results- Thirty-five women and 186 men were entered. Mean (SD) of age was 52 f ‎‎9.59 in group A, 51.56 ±8.42 in B and 53.21 t 6.45 in C. The involved vessels were ‎LAD, LCX, OM and RCA. Nexus, AVE, Wiktor, Unicath and Multilink were the ‎applied stents. There were three cases of procedural complications and five cases of ‎immediate failure in all three groups. Ten cases of restenosis occurred in group A, 7 ‎in B and 1 restenosis occurred in C‏.‏
Conclusion- Stent implantation with or without predilatation is of great value in the ‎treatment of patients with multi-vessel coronary diseases and can reduce the long-‎term risk of restenosis compared to groups who had PTCA alone (p<0.001). ‎Furthermore, stent implantation without predilatation can be safely performed in ‎multi-vessel disease patients as a new, cost-effective, low radiation exposure ‎procedure in comparison to stent implantation with predilatation (Iranian Heart ‎Journal 2003; 4 (4):22-24‎‏). ‏`‏
