Aims: Albumin is a marker of frailty. Scarce data are available on correlations between frailty-related parameters and outcomes in patients undergoing TAVI. This study sought to evaluate the relation between albumin and mortality in TAVI candidates. Methods and results: A total of 150 patients (mean age 81±6 years) undergoing TAVI were included in the study. Patients with pre-procedural albumin >4 g/dl (>40 g/L) (n=71) were compared to those =4 g/dl (=40 g/L) (n=79). The cut-off value of 4 g/dl (40 g/L) was based on the mean value of albumin in the patients included in the study. During a mean follow-up of 2.1 years the survival rate was 72%. Patients in both groups had similar baseline characteristics. The 2.1-year mortality was higher in the low albumin group compared with the normal albumin group (35% vs. 19%, p=0.01). Multivariate analysis indicated that low pre-procedural albumin was independently associated with a more than twofold increase in 2.1-year all-cause mortality (p=0.01, HR=2.28; 95% CI: 1.17-4.44). Low post-procedural serum albumin remained a strong parameter correlated with all-cause mortality (HR=2.47; 95% CI: 1.28-4.78; p<0.01). Conclusions: Baseline albumin can be used as a simple tool that correlates with survival after TAVI. Low albumin is an important parameter associated with all-cause mortality after the procedure.
