Background: The aim of this research was to use the Mehran risk score to classify elderly diabetics with coronary heart disease to assess the preventive effect of trimetazidine on contrast-induced nephropathy (CIN) after percutaneous coronary intervention (PCI) in different risk population. Methods: An uncompromised of 760 elderly diabetics that went through PCI were included in this research. The patients were first divided into three groups in the light of MRS: low-risk, moderate-risk, and high-risk group, then randomized into trimetazidine group and the control group respectively. The first endpoint was the amount of CIN, which is described as a rise in serum creatinine levels by ⩾44.2 μmol/L or ⩾25% ratio within 48 or 72 hours after medication. Second endpoint included differences in creatinine clearance rate (CrCl), blood urea nitrogen (BUN), serum creatinine (Scr), cystatin-C (Cys-C), and the incidence of major adverse events after administration. Results: In the three groups, the incidence of CIN in trimetazidine and control group was 5.0% versus 4.9%(χ2 = 0.005, p > 0.05), 8.0% versus 18.0% (χ2 = 7.685, p < 0.05), 10.4% versus 27.1% (χ2 = 4.376, p < 0.05), respectively. The multivariable logistic regression result demonstrated that trimetazidine intervention was a profitable element of CIN in moderate and high-risk groups (OR = 0.294, 95% CI 0.094-0.920, p = 0.035). Conclusion: Our study confirmed that trimetazidine can be considered for preventive treatment of CIN occurrence in elderly diabetics with moderate and high-risk population, while there is no obvious advantage compared with hydration therapy in low-risk patients.
