A Risk Score for No Reflow in @entity1 With ST-Segment Elevation XXXX After Primary Percutaneous Coronary Intervention.

@entity1 @entity583 @entity11598 @entity715 @entity413
BACKGROUND: Many factors are associated with @entity11598 ( @entity11598 ) phenomenon in @entity583 ( @entity583 ), including plasma @entity413 , age, and pre-percutaneous coronary intervention (PCI) @entity715 score. Initial clinical assessment would benefit from accurate @entity11598 prediction. This study aimed to develop a simple scoring system to predict the risk of @entity11598 in @entity1 undergoing primary PCI with @entity583 . METHODS: Baseline clinical and procedural variables were used for risk score development (the training dataset, n   =   912) and validation (the test dataset, n   =   864). Independent predictors of @entity11598 from the multivariable model were assigned integer weights based on their coefficients and incorporated into a risk score. The discriminant ability of the score was tested by receiver operating characteristic analysis using the test dataset. RESULTS: The final model included 7 significant variables, which were age, pain-to-PCI time, neutrophil count, admission plasma @entity413 level, pre-PCI @entity715 score, collateral circulation, and Killip class. All these variables were then used to build a risk score in terms of the prediction of @entity11598 . Receiver operating characteristic analysis demonstrated good risk prediction with a c statistic of 0.800 (95% confidence interval: 0.772-0.826) in the test dataset. CONCLUSIONS: In @entity1 with @entity583 treated by primary PCI, incidence of @entity11598 phenomenon may be predicted with an acceptable accuracy based on a 7-item simplified risk score.
