Abstract
- Introduction: The prognostic value of objective nutritional indexes has been demonstrated in many diseases. This study evaluated the prognostic value of these indexes in patients who underwent transcatheter aortic valve replacement (TAVI).<br />Material and Methods: Totally, 119 consecutive patients who underwent TAVI between January 2016 and December 2018 were evaluated. All patients were followed-up for one year. Objective nutritional index (geriatric nutritional risk index [GNRI], prognostic nutritional index [PNI]) and controlling nutritional status [CONUT]) scores were calculated before TAVI.<br />Results: Mean age of the study population was 77.1 ± 7.8 years (59.7% female). During one-year follow-up, 31 (26.1%) deaths were observed. In a Kaplan-Meier analysis, mortality rates were significantly increased in patients with lower GNRI and PNI and higher CONUT scores (50.01% vs. 4.4%; p < .001, 48.1% vs. 15.2%; p < .001, 57.5% vs. 12.8%; p < .001, respectively). Pairwise comparisons of the ROC curves demonstrated that the GNRI score was a significantly better predictor of mortality than the PNI and CONUT scores (area under curve; 0.898, 0.664, and 0.722, respectively, for both; p < .001). According to Cox proportional hazard analyses, the GNRI (hazard ratio [HR]: 0.898) and STS (HR: 1.359) score were independently associated with increased 1-year mortality (for all p < .05).<br />Conclusion: The GNRI, PNI and CONUT scores were associated with 1-year all-cause mortality in patients who underwent TAVI. The predictive value of the GNRI score was significantly better than the PNI or CONUT scores. Assessment of the GNRI should be considered before TAVI.
