Additional independent risk factors for CIAKI included female gender, age >70 years, congestive heart failure (CHF), AMI, diabetes history, multi-vessel disease, eGFR, CKD, contrast agent dose, anemia, proteinuria, albumin <35 g/l, uric acid >420 μmol/l, and left ventricular ejection fraction (LVEF) <40% (Table 3). This evidence concerns the gene ALB and congestive heart failure.
