Premier Heart's MCG system has proven its ability to detect local or global ischemia in multiple independently reviewed clinical trials
Premier Heart's MCG system is founded on the principles of evidence-based medicine. As such, we believe that the best way of demonstrating the accuracy and capabilities of our technogy is through well designed double-blind clinical trials coupled with ongoing analysis and review of our system's performance in daily clinical practice.
This page presents an overview of our peer-reviewed clinical trial results. It includes summary data for each trial as well as electronic copies of the peer-reviewed articles detailing the methods used in each study.

Summary Data: Clinical Trials 2000—2004
This summary includes statistical information from our clinical trials between 2000 and 2004, representing a sample of over 1,000 patients in three major geographic regions (North America, Europe and Asia).
All studies in this group were performed in accordance with Premier Heart's Westchester Study Protocol, utilizing standard double-blind testing and independent verification of results.
Overall sensitivity across these studies was 91% (specificity 83.8%, positive predictive value 77.6%, negative predictive value 92.4%).

The trials below were conducted with our first generation 3DMP and 3DMP/mfEMT software suite — MCG shares the underlying diagnostic technology and produces identical results.
Westchester Medical Center — New York, USA
Results were published in Heart Disease 2002; 4: pp 2-12.
Trial Article This study compared the results from MCG with the results of coronary angiograms in a random sample of 136 patients.
This study showed a sensitivity of 93.3% (specificity 83%, positive predictive value 91.2%, negative predictive value 86.7%).
Siegburg Heart Center — Siegburg, Germany
Two studies were performed at the Siegburg heart center in Siegburg, Germany, evaluating MCG in patient populations with and without a history of revascularization.Results were published in International Journal of Medical Sciences 2007 4(5): pp 249-263.
Trial Article
Monitor LetterThe first study evaluated the use of MCG in a set of 423 patients with no prior history of coronary revascularization.
In this study our technology showed a sensitivity of 89.1% (specificity 81.1%, positive predictive value 79%, negative predictive value 90%).
Results were published in International Journal of Medical Sciences 2008 5(2): pp 50-61.
Trial Article
Monitor LetterThe second study evaluated the ability of our technology to deal with the special challenges of patients with a prior history of coronary revascularization, testng in a sample of 172 patients.
In this study our technology showed a sensitivity of 90.9% (specificity 88%, positive predictive value 62.7%, negative predictive value 97.8%).
