CONCLUSIONS Among patients treated with HFNC post-extubation of those who had a higher ROX index were less likely to undergo reintubation.BACKGROUND The impact of revascularization of coronary chronic total occlusion (CTO) on survival is unknown. Several studies, which included subjects with varied coronary anatomy, suggested that CTO revascularization improved survival. However, the contribution of CTO revascularization to improved outcome is unclear since it was more commonly achieved in subjects with fewer co-morbidities and less extensive coronary disease. OBJECTIVES To study the association between CTO revascularization and survival in patients with uniform coronary anatomy consisting of isolated CTO of the right coronary artery (RCA). METHODS A registry of 16,832 coronary angiograms was analyzed. We identified 278 patients (1.7%) with isolated CTO of the RCA who did not have lesions within the left coronary artery for which revascularization was indicated. Survival of 52 patients (19%) who underwent successful percutaneous coronary intervention was compared to those who did not receive revascularization. RESULTS Revascularized patients were younger (60.2 vs. 66.3 years, P = 0.001), had higher creatinine clearance (106 vs. 83 ml/min, P less then 0.0001), and had fewer co-morbidities than those who did not receive revascularization. Lack of CTO revascularization was a univariable predictor of mortality (hazard ratio [HR] = 2.65, 95% confidence interval [95%CI] 1.06-6.4) over 4.3 ± 2.5 years of follow-up. On multivariable analysis, the only predictors of mortality were increased age (HR 1.04, 95%CI 1.01-1.07), reduced creatinine clearance (HR 1.02, 95%CI 1.01-1.03), and ejection fraction below 55% (HR 2.24, 95%CI 1.22-4.11). CONCLUSIONS Among patients with isolated RCA CTO who underwent extended follow-up, r
