OBJECTIVE: In this study, we aimed to evaluate whether the trimetazidine administration before CAG and/or PCI reduces the incidence of contrast-induced nephropathy (CIN). We also aimed to evaluate the factors affecting the effect and the certainty of the evidence.

MATERIALS AND METHODS: A systematic literature search was performed to obtain studies that assess trimetazidine’s effect on the incidence of CIN in CAG/PCI patients up until 21 January 2021 through PubMed, Embase, and Scopus. The main outcome is CIN, defined as the increase in serum creatinine level ≥ 0.5 mg/dL (44.2 mmol/L) or > 25% of the baseline value 48-72 h after contrast media (CM) administration.

RESULTS: This systematic review and meta-analysis includes seven studies involving a total of 1590 patients. The prevalence of CIN was 11% [8%, 14%]. CIN’s prevalence was 6% [4%, 8%] in the trimetazidine group and 16% [12%, 20%] in the control group. Trimetazidine use is associated with a lower incidence of CIN (RR 0.46 [0.34, 0.63], p<0.001; I2: 0%) with a high certainty of evidence, with an absolute risk reduction of 78 fewer per 1000. Subgroup analysis in patients with renal insufficiency showed that trimetazidine lowers the risk of CIN (RR 0.40 [0.26, 0.61], p<0.001; I2: 0%). The CIN reducing effect of trimetazidine was not significantly influenced by the age (p=0.960), body mass index (p=0.816), hypertension (p=0.595), diabetes (p=0.362), ejection fraction (p=0.261), baseline serum creatinine (0.579), and contrast media volume (p=0.958).

CONCLUSIONS: Trimetazidine administration decreases the risk of CIN in patients undergoing CAG/PCI.
