Urine test for heart disease shows promise

"A urine test to detect coronary artery disease has worked well in a small trial, German researchers report. The test looks for fragments of the protein collagen, which plays a major role in blocking heart arteries, said study author Dr. Constantin von zur Muehlen, a fellow in cardiology at University Hospital Freiberg. He was scheduled to report the findings Wednesday at an American Heart Association meeting in Washington, D.C." - HealthDay News
