Consecutive patients having percutaneous coronary intervention (PCI) over a period of 9 years at a large tertiary care center with available creatinine measurements both before and within 48 hours after the procedure were included; patients on chronic dialysis were excluded. Patients treated between 2012 and 2017 comprised the derivation cohort (n=14,616) and those treated from 2018 to 2020 formed the validation cohort (n=5,606). The primary endpoint is contrast-associated acute kidney injury (CA-AKI, defined per Acute Kidney Injury Network \[AKIN\]). In addition, independent predictors of CA-AKI will be derived from multivariate logistic regression analysis. Model 1 will include only preprocedural variables, while Model 2 will also include procedural variables. A weighted integer score based on the effect estimate of each independent variable will be used to calculate the final risk score for each patient. Impact on 1-year mortality will be also evaluated.
