Philip, 44, worked out, played golf, and died suddenly of a massive heart attack. Pat, 57, didn’t know she had high blood pressure and diabetes--until they led to her heart attack. Robin, 42, knew that an inherited form of high cholesterol put her at risk, but her first of multiple heart attacks caught her by surprise.

Heart disease is the number one killer in America and one of the nation’s greatest health challenges for both men and women. More than half of all people who die of heart disease succumb without warning--the other half have the disease lurking in their body for years before it strikes. And while there is no cure, doctors are learning remarkable new things about the disease, including where it starts, how it occurs, and what that means for us.

Following the documentary, Larry King of CNN's Larry King Live and founder of the Larry King Cardiac Foundation hosts a half-hour discussion featuring some of the country's top medical experts and physicians who present important strategies and practical tactics for improving the health of your heart.

DVD special features include: 10 Easy Steps to a Healthier Heart from Reader’s Digest Magazine; Heart-Healthy Recipes from Real Simple magazine, chef and television host Ming Tsai, and PBS Kids shows Arthur, Zoom, and Postcards from Buster; and bonus interview with Larry King about his own heart disease experiences. Described video for the visually impaired is available on The Hidden Epidemic-Heart Disease in America, and for Take One Step For a Healthy Heart with Larry King.
