Risk factors of contrast-induced nephropathy after percutaneous coronary intervention: a retrospective analysis.
2021
OBJECTIVE Contrast-induced nephropathy (CIN) is a serious complication in patients with acute coronary syndrome (ACS) and percutaneous coronary intervention (PCI). This study aimed to analyze the potential risk factors for CIN in patients undergoing PCI. METHODS Patients with ACS who underwent PCI treatment from January 2017 to January 2020 were selected. The patients' characteristics and medical information were collected and compared. RESULTS A total of 1331 patients undergoing PCI were included. The incidence of CIN was 15.33%. Logistic regression analyses showed that a left ventricular ejection fraction ≤45% (odds ratio [OR] 4.18, 95% confidence interval [CI] 1.10-7.36), serum creatinine levels ≤60 μmol/L (OR 3.03, 95% CI 1.21-5.57), age ≥65 years (OR 2.75, 95% CI 1.32-4.60), log N-terminal pro-B-type natriuretic peptide levels ≥2.5 pg/mL (OR 2.31, 95% CI 1.18-5.13), uric acid levels ≥350 μmol/L (OR 2.29, 95% CI 1.04-5.30), emergency percutaneous intervention (OR 1.35, 95% CI 0.34-3.12), and triglyceride levels ≤1.30 mmol/L (OR 1.10, 95% CI 0.01-2.27) were independent risk factors for CIN in patients who underwent PCI. CONCLUSIONS Early prevention is required to reduce the occurrence of CIN in patients who undergo PCI and have risk factors for CIN.
