[MO-3] Clinical Significance of Geriatric Nutritional Risk Index for Critical Limb Ischemia Patients who Underwent Endovascular Therapy
【Objectives】
The geriatric nutritional risk index (GNRI) is a simple nutritional assessment tool for elderly subjects. GNRI is calculated as follows: 14.89 × serum albumin (g/dl) + 41.7 × body mass index/22. The aim of this study was to investigate association of GNRI and the prognosis of CLI patients.
【Methods】
Eighty-nine Critical Limb Ischemia (CLI) patients classified as Rutherford class 5 or 6 (mean age, 78.0±9.0 years) who underwent EVT in our hospital were retrospectively reviewed. Amputation-free survival (AFS) within 1 year after the procedure were evaluated.
【Results】
GNRI=95.4 was taken as cutoff value of high risk of amputation for CLI patients via using receiver operating characteristic (ROC) curve. Patients with GNRI≧95.4 showed significantly higher one-year AFS rate, compared to GNRI<95.4 (87.5% vs. 50.9%, P<0.01, see figure). Analyzed by Cox proportional hazards model, GNRI was the independent predictor for AFS within 1 year.
【Conclusion】
GNRI is useful for predicting the prognosis of CLI patients who underwent EVT.
