An Implantable Heart-Attack Monitor From AngelMed

Technology Review -- An implantable device that alerts high-risk patients when they show signs of a heart attack could shorten the time it takes for the wearer to seek medical attention. The device, being developed by AngelMed, a medical-devices company in Shrewsbury, NJ, is already approved for use in Brazil and is now undergoing clinical testing in the United States. While early tests show that it can detect heart attacks, the impact on a patient's long-term outcome is not yet clear: tests of other cardiac devices have found that detecting problems earlier doesn't always translate into better health for patients.
