April 4, 2011 β A non-invasive cardiac test will be on display at the Scientific Sessions and Expo of the American College of Cardiology in New Orleans. The Multifunction CardioGram (MCG), from Premier Heart, offers completely non-invasive cardiac testing using power estimate as an aid to assist physicians in diagnosis.
The device is a chemical and radiation-free procedure, and has been shown in published clinical trials to be associated with little risk of adverse events to the patient.
"Using a computational systems analysis approach we, as physicians, now have a method that analyzes and compares raw electro-cardiac data to help identify significant CAD (coronary artery disease) and which has been shown in multiple studies to assist in accurate detection the presence of significant coronary artery disease requiring intervention with improved specificity and negative predictive values,β said Joseph T. Shen, M.D., founder of Premier Heart and the lead developer of the device.
It works by sampling a signal from two left ventricular leads (V5 and II) and performing a series of digital signal analysis operations. The operations produce a sequence of indexes, which quantify abnormalities in the mathematically transformed electro-cardiac data. This information is transferred via the Internet to Premier Heart in New York, where it is compared to a database of over 40,000 patients. A numeric score is assigned based on this analysis representing the likelihood and severity of CAD. This score is reported back to physicians within minutes to aid in detection and diagnosis in a point of care setting."
