Abstract:
Chronic total occlusions (CTOs) are present in more than one third of older patients with myocardial ischemia, but controversy remains about the best therapeutic approach. Aims To compare long‐term survival after CTO revascularization (percutaneous coronary intervention [PCI] or coronary artery bypass graft [CABG] ) versus medical treatment (MT) alone in patients aged 75 and older. Methods and results A total of 1,252 consecutive patients with at least one CTO were identified from 2010 to 2014 in our center. Patients were stratified by age ( 〈 75 years vs. ≥75 years) in the present analysis. All‐cause and cardiac mortality were assessed at a median follow‐up of 3.5 years. In the older subgroup (26%), patients were more likely to be treated with MT alone (71% vs. 43% of younger patients; p 〈 0.001). Patients undergoing revascularization were younger and had higher left ventricular ejection fraction (LVEF) and lower age, creatinine, ejection fraction (ACEF) score (age/LVEF +1 if creatinine 〉 2.0 mg/dL), compared to the MT group ( p 〈 0.05). As compared to MT, revascularization predicted lower rates of cardiac mortality and all‐cause mortality in older patients, both in the subgroups treated with CABG (hazard ratio [HR] 0.35, 95% confidence interval [CI] 0.17–0.71; HR 0.39, 95%CI 0.18–0.81) and PCI (HR 0.57, 95%CI 0.33–0.98; HR 0.59, 95%CI 0.28–1.2). No differences in mortality were observed according to type of revascularization procedure. Conclusions Among patients aged at least 75 years with a CTO, revascularization (PCI or CABG) rather than MT alone may portend a better outcome in terms of all‐cause and cardiac mortality.
