This study evaluated the long-term prognosis of optimal'stent-like'results, suboptimal results and failure of balloon angioplasty. The clinical data of 108 patients were examined during 8 years following balloon angioplasty. Based on the angiographic results, the patients were divided into 3 groups:Group A(n=59), <25% residual stenosis(ie, optimal stent-like result);Group B(n-43), 26-50% residual stenosis or large dissection(ie, suboptimal result);and Group C(n=6), >50% residual stenosis or stenosis could not be crossed(ie, failed angioplasty). Restenosis occurred in 20 of 43 patients(46.5%)in Group B, but only in 18 of 59 patients(30.4%)in Group A. Achieving stent-like results following balloon angioplasty significantly reduced the incidence of restenosis. Kaplan-Meier curves at 8 years demonstrated a survival rate without serious cardiac events of 83% in patients with stent-like results compared with 58% in those with suboptimal results and 17% in those with failed balloon angioplasty. In conclusion, the major finding of this study is that achieving stent-like results following balloon angioplasty reduces the incidence of restenosis, and 8-year survival without serious cardiac events after balloon angioplasty is significantly better in patients who have a stent-like result.
