Introduction: Chronic inflammation has been associated with adverse long-term outcomes in transcatheter aortic valve implantation (TAVI) patients, however no specific markers have yet been validated. (1) Previous research has shown a potential impact of RDW/albumin (RAR) and CRP/albumin (CAR) on mortality and complications in diseases such as myocardial infarction and COVID-19. Research on these parameters is scarce in chronic diseases, and so far RAR and CAR have not been studied in TAVI patients. The aim of our research is to determine if RAR and CAR have effects on survival and complications post-TAVI.

Patients and Methods: Our study included 547 patients who underwent TAVI at Dubrava University Hospital from 2012 do 2024, followed to present date. RDW, CRP and albumin were collected through routine blood samples drawn at admission. Using ROC analysis, we determined cut-off values for RDW/albumin (0.35) and CRP/albumin (0.08). Primary outcome of the study was all-cause death in follow up and secondary outcome was major adverse cardiac event (MACE) in follow up. Data was collected through in-person visits and telephone check-ups.

Results: Sociodemographic and clinical characteristics of the patients are shown inTable 1. Median RAR was 0.35 (IQR 0.32-0.40), while median CAR was 0.08 (IQR 0.03-0.17). Our analysis showed a significant difference in survival post-TAVI in patients with elevated RAR (14 vs 45 months, P 0.001; HR 2.61, 95% CI 1.79-3.82) and CAR (15 vs 23 months, P 0.017; HR 1.55, 95% CI 1.08-2.24). There was no difference in MACE during follow-up in either group.

Conclusion: CAR and RAR are derived from parameters used in routine practice that can be easily utilized and have the potential to be used as predictive markers of survival post-TAVI. Further research is neccessary to establish exact cut-off values for TAVI patients, allowing for use in clicinal practice, which in turn could impact how we treat patients at risk.
