GERIATRIC NUTRITIONAL RISK INDEX IS A PREDICTOR OF RECURRENT PERCUTANEOUS CORONARY INTERVENTION IN PATIENTS WITH NON-ST SEGMENT ELEVATION MYOCARDIAL INFARCTION

Aim To investigate the relationship between malnutrition and follow-up cardiovascular (CV) events in non- ST-segment elevation myocardial infarction (NSTEMI). Material and methods A retrospective study was performed on 298 patients with NSTEMI. The baseline geriatric nutritional risk index (GNRI) was calculated at the first visit. The patients were divided into three groups according to the GNRI: >98, no-risk; 92 to <= 98, low risk; 82 to <92, moderate to high (MTH) risk. The study endpoint was a composite of follow-up CV events, including all-cause mortality, non-valvular atrial fibrillation (NVAF), hospitalizations, and need for repeat percutaneous coronary intervention (PCI). Results Follow-up data showed that MTH risk group had significantly higher incidence of repeat PCI and all-cause mortality compared to other groups (p<0.001). However, follow-up hospitalizations and NVAF were similar between groups (p>0.05). The mean GNRI was 84.6 in patients needing repeat PCI and 99.8 in patients who did not require repeat PCI (p<0.001). Kaplan Meier survival analysis showed that patients with MTH risk had significantly poorer survival (p<0.001). According to multivariate Cox regression analysis, theMTH risk group (hazard ratio=5.372) was associated with increased mortality. Conclusion GNRI value may have a potential role for the prediction of repeat PCI in patients with NSTEMI.
