Emmy Award Winning The heart is the engine of human life. Beating almost 100,000 times a day, more than 36 million times each year, it endures abuse and trauma with extraordinary resilience. Yet, as more nations become... more » prosperous and lifestyles change, heart disease has become the world's number one killer of men and women alike. In America alone, approximately 3,000 people each day die from cardiovascular disease. Each of the three programs that make up, THE MYSTERIOUS HUMAN HEART focuses on a different aspect of what we thought we knew, what we know now, and what we're on the verge of learning about the heart. This material is presented through the real-life dramas of people who suddenly learn that a normal, functioning heart is not something that can be taken for granted. Programs in this series:
