The impact of stenting on small vessels (<3.0 mm) with complex lesions (B2-C) is still controversial. Restenosis rate in this population is high (> 40%). We compared early and late outcome of patients with complex coronary lesions in small vessel treated with traditional coronary angioplasty (angioplasty group) and with elective stent implantation (stent group). Angioplasty group (n = 97) and stent group (n = 112) were comparable for all clinical and angiographic characteristics. All patients in the two groups had clinical and angiographic follow-up. Major adverse cardiac events (MACE) and restenosis rate were evaluated. No patients in the two groups experienced in- hospital death or bypass surgery. Myocardial infarction occurred in four patients in the angioplasty group and in seven patients in the stent group (P = 0.36). No patients in either the angioplasty or the stent group had acute stent thrombosis, whereas subacute stent thrombosis occurred in only one patients of the stent group (0.9%). Long-term MACEs (20 ± 4 month) were not different in the two groups (angioplasty group 39% vs. stent group 44%, P = 0.35). Target lesion revascularization rate was 33% in the angioplasty group and 34% in the stent group (P = 0.50). Restenosis rate was not statistically different in the two groups (stent group 41% vs. angioplasty group 38%, P = 0.41). In conclusion, compared to balloon angioplasty, elective stent implantation in small vessels with complex lesions does not improve early and late outcome. (C) 2000 Wiley-Liss, Inc.
