What is Noninvasive Estimation of Myocardial Oxygen Consumption about?

To estimate the proportion of CP patients eligible for cholesterollowering therapy and assess the reliability of ED cholesterol values. Methods: This was a secondary analysis of a cohort study of patients with CP who received an ECG and were hemodynamically stable. The study was conducted in the emergency (urgent care) department of a Veterans Administration Hospital. Methods: Presenting characteristics, final diagnosis of acute cardiac ischemia (ACI), proportion with elevated total cholesterol levels (>200 mg/dL) at the ED visit and agreement with subsequent outpatient testing. Results: Of 102 patients with available data, mean age was 59.2 years (range 21 to 90 years, SD• 73.8% were African Americans, 100% were male, and 17.5% had a final diagnosis of AC1. The prevalence of hypercholesterolemia in the ED was 36.3% (95% confidence interval [CI] 0.27 to 0.46). The mean total cholesterol value in the subgroup (n=36) with an elevated ED value was 225 mg/dL (SD 24 mg/dL), not statistically different from their outpatient results (218 mg/DL; SD 32 mg/dL) (P=. 17, paired t test). Overall agreement between ED and outpatient values (at the cutoff of >200 mg/dL) was 78.4% with a K of 0.52
