Sound advice on improving cardiac health through altering exercise, diet, stress response, and other lifestyle habits--all of which, however, has been equally well-presented in previous guides. Warren (Ohio State University College of Medicine) and Subak-Sharpe are officially presenting the sound Duke University Preventive Approach to Cardiology, and its program; as they accurately point out, ""there is nothing radical about DUPAC: it is built around exercise conditioning, dietary modification, stress management, and smoking cessation."" The authors explain how the heart works, what risk factors predispose one to developing disease (of these, only age and family history cannot be altered), the types of heart disease, and their treatment. They then move on to discuss each aspect of the program in detail. Specific exercises are clearly set forth, and serviceable recipes are included in the nutrition advice. Though the authors occasionally fall into the medical-lingo trap (""congestive heart failure. . . is characterized by an enlarged heart with a progressive pumping impairment""), they are generally straightforward and plain-spoken. Responsible, but nothing new.
