Valenti R, Migliorini A, De Gregorio MG, et al. - Using the Florence CTO-PCI registry, researchers examined elderly patients (≥ 75 years) who underwent chronic total occlusion (CTO) percutaneous coronary intervention (PCI) between 2004 and 2015, to determine the prognostic influence of successful CTO-PCI and completeness of revascularization in this age group of patients. For this purpose, they used Kaplan–Meier estimation and Cox multivariable regression analysis. Long-term cardiac survival was the endpoint. In 57% of patients, completeness of revascularization was accomplished. At multivariable analysis, the factors that were independently related to long-term cardiac survival were increasing age, diabetes, chronic kidney disease, left ventricular ejection fraction < 0.40, and completeness of revascularization. Findings revealed a long-term survival benefit in relation to successful CTO-PCI in the elderly. Considering a CTO-PCI attempt even in the elderly was recommended in order to achieve complete coronary revascularization.
