Americaís number-one killer, heart disease, can exist in the absence of symptoms. Called "silent heart disease," its first manifestations can be catastrophic. This no-nonsense guide now addresses this and other new issues in a clear, non-technical way and examines old concerns from a fresh perspective. The text moves easily from the role of smoking, stress, diet, and exercise in heart health to the methodology of detection, prevention, and treatment of the disease. Included is everything on the subject from psychology and history to exercise and dinner menus. The book is a must-read for everyone who wants to stay heart-healthy.
