The Renal dysfunction, Congestive heart failure, Hypertension, Age \u226575\u2009years, Diabetes mellitus and prior Stroke R2CHADS2 score, originally developed for thromboembolic risk assessment, has recently been proposed as a predictor of CIN and major adverse cardiovascular events (MACE). The present study aimed to evaluate the predictive value of the R2CHADS2 score for CIN and long-term MACE in STEMI patients undergoing primary PCI (pPCI). A total of 1204 STEMI patients were included in this retrospective study. Patients were categorized into 3 risk groups based on their R2CHADS2 scores. CIN incidence was significantly higher in the high-risk group (37.1%) compared with the moderate (13.6%) and low-risk groups (5.5%;\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2009&lt;\u2009.001).

MACE occurred in 49.3% of the high-risk group, 22.1% of the moderate-risk group, and 12.9% of the low-risk group (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2009&lt;\u2009.001).
