Multivariate logistic regression suggested that HF (adjusted odds ratio [OR] 1.316, 95% confidence interval [CI] 1.088–1.592, p value = 0.005), elderly (OR 1.021, 95% CI 1.011–1.031; p value < 0.001), female (OR 1.249, 95% CI 1.018–1.531, p value = 0.033), elevated levels of CRP (OR 1.009, 95% CI 1.005–1.013; p value < 0.001), and lower rate of use of RAS inhibitors (OR 0.813, 95% CI 0.670–0.987, p value = 0.037) were associated with increased risk of CI-AKI after CAG and PCI (Table 2). This evidence concerns the gene CRP and hydrops fetalis.
