We have been using the CMI 9-channel MCG for detection of ischemia in patients admitted to Cedars-Sinai Medical Center for acute chest pain syndrome. The results are very exciting and have been published in abstracts and one manuscript, with another manuscript in submission (4,5). In summary, we studied 75 patients with acute chest pain and 65 healthy volunteers and found a very strong association with an abnormal MCG scan and ischemia (p<0.0001). The sensitivity, specificity, PPV and NPV was 87.1%, 85.7%, 64.3%, and 95.7%, respectively. In comparison, the diagnostic value of the stress SPECT imaging was 91.3%, 75.0%, 75.0%, and 91.3%, for sensitivity, specificity, positive and negative predictive value, respectively. These results were achieved without the use of stress provocation, contrast administration, or any ionizing radiation, and the results were available immediately.
