The question-and-answer technique familiar to Galton readers is here applied to the problems of heart attack. While this way of packaging information can be handy when applied to specifics--what should you do if you think you're having a heart attack? what happens in the Emergency Room. . . in the Cardiac Care Unit?--it is less effective in supplying background information, discussing risk factors, and providing a general summary of what can be done in prevention, treatment, and cure. Questions like ""Can there be emotional complications? Do they matter?"" are contrived and annoying, while ""What is the second principle of dietary control of high cholesterol?"" clearly belongs in the category of questions-we-doubt-ever-got-asked. With that qualification, the book is a good compendium of information presented at a level suitable for the general reader. Dr. Roth is a cardiologist at Yale's School of Medicine and Director of a Coronary Care Unit. Like other books in the field (most recently The Heart Attack Handbook, p. 461), the text does much to encourage hope and advises sound preventive measures in terms of diet, weight control, exercise, and giving up smoking. It also includes a glossary, a guide to the major drugs used in treating heart disease, and useful appendices rating foods and suggesting low-fat low-cholesterol meals. ""A"" for information and intent; ""C"" for the Q-and-A style.
