Hong-Li Wu,1 Bater Hurile,1 Zhi-Peng Li,1 Hong-Wei Zhao2 1Department of Cardiology, The Affiliated Hospital of Inner Mongolia Minzu University, Tongliao, People’s Republic of China; 2Department of Cardiology, The Seventh Affiliated Hospital of Sun Yat-sen University, Shenzhen, People’s Republic of ChinaCorrespondence: Hong-Wei Zhao, Email [email protected]: As a nutritional indicator, a lower level of geriatric nutritional risk index (GNRI) has been suggested as a predictor for poor prognosis in acute coronary syndrome (ACS). However, whether GNRI could improve the predictive value of the Global Registry of Acute Coronary Events (GRACE) score for the prognosis in elderly patients with non-ST segment elevation myocardial infarction (NSTEMI) after PCI remains unclear.Methods: A total of 446 elderly patients with NSTEMI after percutaneous coronary intervention (PCI) were consecutively enrolled. Patients were divided into major adverse cardiovascular and cerebrovascular events (MACCE) group and control group according to the occurrence of MACCE during one year follow up. The clinical parameters including GNRI were compared to investigate the predictors for MACCE. The performance after the addition of GNRI to the GRACE score for predicting MACCE was determined.Results: A total of 68 patients developed MACCE. In unadjusted analyses, the rate of MACCE was significantly higher in the 93.8
