Abstract
Objective: To describe frailty, nutritional status, and score correlations before percutaneous coronary intervention (PCI). Methods: This observational study included retrospective data and analyzed 71 complete, valid records from January-September 2026. Spearman correlations and Mann-Whitney tests were used with multiplicity adjustment. Results: Mean age was 74.1 ± 7.2 years; 59.2% were men. MNA-SF ≤11 occurred in 29/71 cases (40.8%). Frailty prevalence using EFS ≥8, FRAIL ≥3, and CFS ≥5 was 2.8%, 5.6%, and 22.5%, respectively. MNA-SF correlated inversely with EFS (ρ = -0.529), FRAIL (ρ = -0.539), and CFS (ρ = -0.424). No significant correlations with length of stay were observed. Conclusion: Nutritional risk was common and associated with higher frailty scores. Prevalence estimates depended on the assessment tool and threshold.
