the wall of the heart. The initial concept of TMR was that blood supply would
flow through these channels and supply oxygen to the heart muscle. TMR may relieve angina. But how TMR works is not well understood.

attack," says Jean C. McSweeney, Ph.D., R.N., nurse researcher at the
University of Arkansas for Medical Sciences. In an award-winning research
project, she interviewed hundreds...
