Fairly large lobulated t2 intermediate to hyperintense masses are seen in the body of corpus callosum extending into the left frontal lobe and the left high fronto parietal region with surrounding edema
Answers
Explanation:
The Global Registry of Acute Coronary Events (GRACE) risk score has been extensively validated to predict risk during hospitalization in patients with acute coronary syndrome (ACS). Recently, serum calcium has been suggested as an independent predictor for in‐hospital mortality in patients with ST‐segment elevation myocardial infarction; however, the relationship between the 2 has not been evaluated.
Hypothesis
The combination of GRACE risk score and serum calcium could provide better performance in risk prediction.
Methods
The study enrolled 2229 consecutive patients with ACS. Independent predictors were identified by a multivariate logistic regression model. The incremental prognostic value added by serum calcium to the GRACE score was evaluated by receiver operating characteristic, net reclassification improvement (NRI), and integrated discrimination improvement (IDI).
