Heart Beat

The Mysterious Human Heart

One thing we wish we could do, but can't, is show you how the heart works or what ails it. A three-part series airing on PBS does just that. "The Mysterious Human Heart" delves into how this hardworking muscle beats, what can go wrong with it, and how heart disease is treated. One of the driving forces behind the series is Dr. Peter Libby, whose work on atherosclerosis has changed our understanding of how heart attacks happen. The series will air on many PBS stations on Oct. 15 and Oct. 22 at 9 p.m. Eastern time. Some may show it at other times, so check your local television listings.
