A Simple Nomogram to Predict Contrast-Induced Acute Kidney Injury in Patients with Congestive Heart Failure Undergoing Coronary Angiography

Table 3

Multivariable logistic regression analysis of CI-AKI.

Variable	β	OR (95% CI)	value
Age, years	0.04	1.04 (1.02–1.06)	0.001
IABP vs. no IABP	1.38	3.97 (2.14–7.37)	<0.001
AMI vs. no AMI	1.18	3.27 (2.09–5.10)	<0.001
CKD vs. no CKD	1.04	2.83 (1.80–4.44)	<0.001

CI-AKI: contrast-induced acute kidney injury; IABP: intra-aortic balloon pump; AMI: acute myocardial infarction; and CKD: chronic kidney disease.
