However, data of its predictive strength in the context of primary PCI are not available. Therefore, in this study, we have assessed predictive value of CHA2DS2-VASc score for CI-AKI after primary PCI.Methods: This analytical cross-sectional study was conducted between January 2021 and June 2021 at the National Institute of Cardiovascular Diseases (NICVD), Karachi, Pakistan. Inclusion criteria of the study was consecutive adult patients who had undergone primary PCI. Baseline CHA2DS2-VASc score was calculated, and either a 25% or 0.5 mg/dL increase in post-procedure serum creatinine level as compared to baseline level was categorized as CI-AKI.Results: A total of 691 patients were included, of which 82.1% (567) were male. CI-AKI after primary PCI was observed in 63 (9.1%) patients, out of which 66.7% (42) of patients had CHA2DS2-VASc score of ≥ 2. The area under the curve (AUC) for the score was 0.725 [0.662 to 0.788] with a sensitivity and specificity of 66.7% [63.1% to 70.2%] and 66.7% [53.7% to 78.1%], respectively, at a cut-off value of ≥ 2. In multivariable analysis, left ventricular ejection fraction ≤ 30% and CHA2DS2-VASc ≥ 2 were found to be independent predictors with adjusted odds ratios of 2.19 [1.06– 4.5] and 2.13 [1.13– 4.01], respectively.Conclusion: CHA2DS2-VASc score has a good predictive value for the prediction of CI-AKI after primary PCI. Criteria of CHA2DS2-VASc ≥ 2 can be used for the risk stratification of CI-AKI after primary PCI.Keywords: ST elevation myocardial infarction, STEMI, percutaneous coronary intervention, primary PCI, contrast-induced acute kidney injury, CI-AKI, CHA2DS2-VASc score, contrast-induced nephropathy, CIN
