However, only the baseline serum creatinine (OR = 1.31, 95% CI: 1.04–1.63, p = 0.013), use of ACE inhibitors or ARBs (OR = 2.00, 95% CI: 1.18–3.43, p = 0.011), RBC transfusion volume (OR 1.12, 95% CI 1.02–1.23, p = 0.027), and history of CAD (OR = 2.22, 95% CI: 1.1–4.52, p = 0.029) were significant risk factors for AKI after adjusting for age, gender, diabetes, hypertension, history of CAD or CVA, use of ACE inhibitors or ARBs, and baseline serum creatinine. The gene discussed is ACE; the disease is coronary artery disorder.
