'Electronic Stethoscope' Hears Coronary Disease

So who is going to do the research, testing this on the vertebral and carotid arteries? With easier diagnosis maybe more endarterectomies could be done, preventing more strokes.  The ASA and NSA would be well suited for this, it doesn't require any real work and pushes what work there is to doctors.

The sensitivity and specificity of a digital stethoscope to predict CAD were 90% and 58% compared with CT angiography (P=0.0007), researchers reported online in the American Journal of Cardiology.
The study included 166 patients without known CAD, 60% of whom were men with a mean age 57. They were referred to CT angiography. The stethoscope, called the Cardiac Sonospectrographic Analyzer (CSA), identified 19 patients with at least one coronary artery with a greater than 50% blockage, according to Amgad Makaryus, MD, of North Shore University Hospital in Manhasset, N.Y., and colleagues.
The presence of CAD identified by the stethoscope had no association with the presence of hypertension, dyslipidemia, or obesity.
The FDA-approved device is placed in nine different positions on the chest and detects microbruits -- subaudible bruits too faint to be heard through standard auscultation -- that reflect the difference in coronary blood flow when obstructions make it more turbulent.
