Abstract: ObjectiveTo investigate the effect of percutaneous coronary intervention (PCI) treatment on quality of life and prediction in patients with chronic total occlusion.Methods87 patients with chronic total occlusion who had underwent PCI to revascularization were studied. 57 cases had successfully revascularized and implanted stenting. 30 cases failed to revascularize. Their activity of living, quality of life and long prediction were observed.ResultsAfter 6～60 months follow-up, the quality of life in patients with successful revascularization was much better than that in patients who failed to revascularize. Mortality between these two groups showed no significant difference. ConclusionSuccesful revascularization by PCI on chronic total occlusion can improve quality of life.

Key words: chronic total occlusion, coronary angioplasty, quality of life
