Sudden cardiac arrest (SCA) is the leading cause of death in the United States, accounting for approximately 300,000 deaths annually - more than lung cancer, breast cancer and HIV/AIDS combined. Out-of-hospital survival is less than 8 percent, making prediction and prevention critically important.
There are an estimated 10 to 12 million heart attack and heart failure patients in the United States who can benefit from annual MTWA testing. Microvolt T-Wave Alternans is a marker of SCA risk that is measured during a non-invasive treadmill test.
