What are some disadvantages of the Multifunction Cardiogram™ system?
While Multifunction Cardiogram™ analysis is more accurate than other diagnostic techniques it is not 100% accurate. Clinical studies have shown that for diagnosis of ischemia due to coronary artery disease the Multifunction Cardiogram™ has a sensitivity of 90% with 7±2% false negative results. Specificity is 85% or better, with 15±3% false positive results. It is possible for a Multifunction Cardiogram™ to report a negative result for a small subset of patients with coronary artery disease. Likewise it is possible for a Multifunction Cardiogram™ to report a positive result for a subset of healthy patients. Additionally, the current generation of a Multifunction Cardiogram™ does not determine the location of coronary artery blockages — A seperate test (angiography) is required for this. Premier Heart is actively researching ways to improve the accuracy and utility of the Multifunction Cardiogram™ technology. We are confident that ongoing research and refinements will continue to improve
