TEWKSBURY, Mass.--(BUSINESS WIRE)--Cambridge Heart, Inc. (OTCBB: CAMH), a developer of non-invasive diagnostic tests for cardiac disease, today announced that a new study published on-line in the Heart Rhythm Journal confirms the value of Microvolt T-Wave Alternans™ (MTWA) testing for identifying patients at risk of sudden cardiac arrest (SCA). The pooled analysis of 2,883 patients shows that MTWA is a statistically significant predictor of SCA in patients whose heart muscle is damaged (ejection fraction less than or equal to 35%), as well as in patients with more preserved cardiac function (ejection fraction > 35%).
