Prognostic Value of the CALLY Index in Predicting All-Cause Mortality After Transcatheter Aortic Valve Implantation: A Two-Year Follow-Up Study

Year: 2026

Type: article

Abstract: Background and Objectives: This study investigated the prognostic value of the C-reactive protein–albumin–lymphocyte (CALLY) index in predicting all-cause mortality among patients undergoing transcatheter aortic valve implantation (TAVI) for severe aortic stenosis. Materials and methods: This retrospective single-center study included 303 patients who underwent TAVI. The CALLY index and other established prognostic scores were calculated at baseline. Patients were followed for a median of 21 months. The primary endpoint was all-cause mortality. Results: A total of 60 patients (19.8%) died during follow-up. The CALLY index demonstrated the highest predictive performance for all-cause mortality, with an AUC of 0.698 (95% CI: 0.628–0.768, p < 0.001). In multivariate Cox regression, a low CALLY index remained an independent predictor of mortality (HR: 3.80, 95% CI: 2.03–7.11, p < 0.001), along with reduced LVEF, chronic kidney disease, and diabetes mellitus. Kaplan–Meier analysis further confirmed markedly worse survival in the high-risk group (log-rank p < 0.001). Conclusions: The CALLY index was independently associated with mortality after TAVI and may represent a complementary biomarker for risk stratification in this population.
