ROC curve for the prediction of PMI. The dotted diagonal line is the null hypothesis with AUC = 0.50. RHI < 1.83 had a sensitivity of 62.7% and specificity of 50.0% to predict PMI with AUC = 0.61 (95% CI 0.51–0.71). AUC, area under the curve; CI, confidence interval; PMI, periprocedural myocardial injury; RHI, reactive hyperemia index; ROC, receiver operating characteristic.
