    Abstract:

    Aim To compare the immediate and long-term outcomes of coronary stenting for total occlusions with nonocclusive stenoses. Methods A total of 516 consecutive patients (687 lesions) underwent coronary stenting. The study population was divided into total occlusion group (TO group, 142 patients with 160 lesions) and non-occlusion group (NO group, 374 patients with 527 lesions). The immediate and long-term angiographic and clinical outcomes were assessed. Results There was no difference in postprocedure minimum lumen diameter (3.12±0.51 vs. 3.13±0.54 mm, p>0.05) between TO and NO groups. There was no difference in incidence of clinical complications between the two groups. A total of 27.8% of patients in TO group and 23.7% of lesions in NO group occurred restenosis (p>0.05). Clinical events occurred in 25.2% of patients in TO group compared with 22.7% in NO group (p>0.05). Conclusions The immediate and long-term outcomes of coronary stenting for total occlusions are comparable to that for nonocclusive stenoses.
