Abstract:
Objective: To analyze influencing factors of percutaneous coronary intervention (PCI) on therapeutic effect in patients with coronary chronic total occlusions (CTO). Methods: Clinical data, lesion features and PCI therapeutic results of 65 patients with 72 CTO lesions, who received PCI in our hospital from Jan 2010 to Dec 2012, were retrospectively analyzed. Results: PCI success rate of CTO lesion was 91.67% (66/72); compared with patients with CTO occlusion 3~12 months, there was significant decrease in PCI success rate (97.78% vs. 81.48%) in those with CTO occlusion >12 months; compared with patients with occlusion length ≤15mm, there was significant decrease in PCI success rate (97.96% vs. 78.26%) in those with occlusion length >15mm; compared with patients with mouse tail-like broken ends, there was significant decrease in PCI success rate (96.55% vs. 71.43%) in those with knife cut-like broken ends, P<0.05 all; PCI failed in six lesions, in which four because guidewire failed to pass through lesions and two because balloon failed to pass through lesions; incidence rate of complications was 7.69% during PCI, there were no major adverse cardiovascular events during admission in all patients; symptoms relieving rate of angina pectoris was 90.16% after PCI. Conclusion: Success rate of percutaneous coronary intervention is related to lesion features, CTO occlusion duration etc.
