Abstract Funding Acknowledgements Type of funding sources: None. Background Primary percutaneous coronary intervention (PPCI) is a treatment of choice in ST elevation myocardial infarction patients (STEMI). However, this approach could increase the risk of contrast induce acute kidney injury (CI-AKI) due to iodinated contrast exposure to the patient. Remote ischemic post conditioning (RIPostC) is a non-invasive and simple method that not only has cardioprotective but also renoprotective effect that could prevent the incidence of CI-AKI. Purpose The aim of this study was to investigate the effect of RIPostC to CI-AKI incident in STEMI patients undergoing PPCI. Methods This study uses pre and post-test only with control group design with experimental research designs. Data was taken at the Instalasi Pelayanan Jantung Terpadu (IPJT) RSUP Dr. M. Djamil Padang from June 2019 until March 2020, there were 66 patients with ST-segment elevation myocardial infarction (STEMI) being performed RIPostC procedure. with intermittent ischaemia and reperfusion applied to the arm through five cycles of 5-min inflation and 5-min deflation of an automated cuff device after crossing wire. Creatinine and eGFR were measured pre and 48 hours post PPCI. CI-AKI diagnosis based on increase of creatinine level >0,5 mg/dL or 25% from baseline value on 48 hours after PPCI. Bivariate analysis was performed to determine the effect RIPostC to incidence of CI-AKI using the Chi-square test. Result A total of 66 patients who underwent the PPCI procedure were divided into two groups RIPostC (n = 33) and without RIPostC (n = 33). The baseline characteristic in both of group was similar. The RIPostC group had a lower CI-AKI incident if we compare with the non RIPostC (15,2% vs 42,4%, p < 0,05). Conclusion RIPostC effectively reduced incidence of CI-AKI in STEMI patient who underwent the PPCI with statistically significant result.
