Background:We investigated whether the outcome of revascularization differed from the outcome of medical therapy in chronic kidney disease (CKD) and non-CKD patients with chronic total occlusion (CTO).Methods and Results:A total of 2,010 patients with CTO who underwent revascularization (n=1,355), including percutaneous coronary intervention (n=878) and coronary artery bypass grafting (n=477), or had medical therapy alone (n=655) were examined. The primary outcome was all-cause death during follow-up. Among the non-CKD patients (n=1,679), revascularization had a lower incidence of all-cause death (adjusted hazard ratio [HR] 0.54, 95% confidence interval [CI] 0.41–0.72, P<0.001) compared with medical therapy. Among the CKD patients (n=331), the difference in the incidence of all-cause death was not as marked between the 2 treatments (adjusted HR 0.71, 95% CI 0.48–1.06, P=0.09). There was a significant interaction between kidney function and treatment strategy (revascularization vs. medical therapy) on all-cause death (P for interaction=0.014).Conclusions:Based on the clinical outcomes, in CTO patients with preexisting CKD, revascularization via PCI or bypass surgery might not be as effective as in non-CKD patients.

Background:Limited data are available on the long-term clinical outcomes of coronary chronic total occlusion (CTO) patients who receive optimal medical therapy (OMT) compared with percutaneous coronary intervention (PCI).Methods and Results:Between March 2003 and February 2012, 2,024 patients with CTO were enrolled in a single-center registry. Among this patient group, we excluded CTO patients who underwent coronary artery bypass grafting and classified patients into the OMT group (n=664) or PCI group (n=883) according to initial treatment strategy. Propensity-score matching was also performed. The primary outcome was cardiac death. The median follow-up duration was 45.8 (interquartile range: 22.8–71.1) months. In the PCI group, 699 patients (79.2%) underwent successful revascularization. In the propensity-score matched population (533 pairs), there was no significant difference in the rate of cardiac death between the OMT and PCI groups (hazard ratio, 1.57; 95% confidence interval, 0.91–2.72, P=0.11). In the subgroup analysis, there were no significant interactions between the PCI strategy and cardiac death among several subgroups except that regarding collateral flow grades 0–2 vs. those with grade 3 (P=0.01).Conclusions:As an initial treatment strategy, PCI did not reduce cardiac death compared with OMT for the treatment of CTO in the drug-eluting stent era.
