Objective: CTO is defined as 100% occlusion of a coronary artery for more than one month. Nutritional status has been shown to be a prognostic marker in many clinical situations. CONUT and PNI scores are objective indices that can be calculated based on simple blood parameters and can be used to evaluate the nutritional status of patients. The aim of this study was to examine the effect of nutritional status assessed by CONUT and PNI on all-cause mortality in patients with CTO.

Material and Method: The retrospective study included 516 patients who had CTO on coronary angiography. The nutritional status of the patients was evaluated with PNI and CONUT scores, and categorical groups were formed according to these results and compared.

Results: All-cause mortality occurred in 127 (24.6%) patients during median follow-up period of 48 months. At the end of the follow-up period, the patients were divided into two groups as survival and non-survival. In terms of all-cause mortality, mean PNI score (47,87±6,31 vs. 42,41±6,57) and median CONUT score (1(2) vs. 3(3)) differed significantly between the surviving and non-surviving groups (p <0.001). Kaplan-Meier analysis showed a significant difference in survival between the PNI and CONUT scores cathegorical groups (p <0.001).

Conclusion: Higher CONUT scores and lower PNI scores were found to be associated with poor outcomes in CTO patients. Evaluation and monitoring of nutritional status in CTO patients by these nutritional scores may provide additional prognostic information.
