LOUISVILLE, Ky. & WALTHAM, Mass.--(BUSINESS WIRE)--Imagine if doctors could easily detect the conditions that cause many heart attacks or strokes – in time to prevent the life-threatening attacks. BG Medicine and Humana (NYSE: HUM) have enrolled 6,822 Humana members in a study intended to develop new diagnostics for predicting heart attacks and strokes in the months or years before they happen. Although effective treatments are likely to exist and several new treatments are being developed, only reliably finding people who are at high risk can make effective prevention of first heart attacks and strokes possible. The Humana members volunteered to participate in the study.
