In this study, we questioned whether soluble suppression of tumorigenesis-2 (sST2), which has thought to play a role in inflammatory processes, cardiac remodeling, and fibrosis could give an idea about the development of CIN in ST-elevation myocardial infarction (STEMI) patients.Patients and Methods: This study is a cross-sectional observational study and includes 357 consecutive STEMI patients. Demographic features, medical history, laboratory parameters, and procedural characteristics were compared according to CIN’s development. The multivariate logistic regression analysis was selected to detect independent risk factors of CIN.Results: In the study, 81 patients (22.7%) who developed CIN were identified. The concentration of sST2 in CIN (+) group was higher than that of CIN (-) group (40.6± 21.0 ng/mL vs 31.5± 13.0 ng/L, p< 0.001). Independent predictors of CIN development were diabetes mellitus (OR, 2.059; 95% CI, 1.093– 3.879; p=0.025), eGFR (OR, 0.983; 95% CI, 0.972– 0.995; p=0.006), lower systolic blood pressure (OR, 0.976; 95% CI, 0.960– 0.993; p=0.006), total procedure time (OR, 1.030; 95% CI, 1.011– 1.049; p=0.002), and sST2 (OR, 1.101; 95% CI; 1.046– 1.160; p< 0.001). Besides, the risk of developing CIN in the high sST2 group is 3.06 times higher than the low group sST2 group regardless of other risk factors.Conclusion: sST2 levels on admission in STEMI patients are useful in predicting CIN development.Keywords: contrast-induced nephropathy, soluble ST2, ST-elevation myocardial infarction, primary percutaneous coronary intervention |
