The ability to identify wall motion abnormalities may be useful for emergency clinicians, but is not typically evaluated in point-of-care echocardiograms. We sought to determine if emergency physicians with basic training in emergency echocardiography could identify regional wall motion abnormalities (RWMA) in patients admitted with ST-elevation myocardial infarction (STEMI). We prospectively enrolled patients with admitted with STEMI. Resident physicians with basic training in emergency ultrasound, blinded to other patient data, performed a point-of-care echocardiogram to evaluate for RWMA. If present, they also recorded the suspected territory of the RWMA. We calculated test performance characteristics and compared the agreement between point-of-care and comprehensive echocardiogram for RWMA and territory. 75 patients with STEMI were enrolled, and 62% had a RMWA. RWMA were identified with excellent test performance characteristics (sensitivity 88% (95% CI 75-96); specificity 92% (95% CI 75-99)). There was substantial agreement between the point-of-care echocardiogram and reference standard (K = 0.79; 95% CI: 0.64-0.94). Emergency physicians with core training in point-of-care echocardiography can accurately identify RMWA.

D011237 Predictive Value of Tests In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
