There has been no insufficiency of books on heart disease--suffice it to say that this one by a professor and the ""cardiologist for the astronauts"" is seemingly excellent, being moderate in advocating weight control, adequate exercise (be careful in the mountains) and general hygienic living. And although Osler first described a heart attack type, the aggressive overachiever will not necessarily do himself in. The affluent society however may--more and more younger men with loving wives serving rich meals are victims. Dr. Lamb discusses the physiology of the heart and circulatory system at some length; environmental changes; diet (not fat alone whether saturated or unsaturated but also carbohydrates and high protein meats); exercise which can kill you along with smoking, coffee, tea and alcohol; the management of the heart attack and the aftermath. However Dr. Lamb is very explicit on the right kind of diet and exercise steadily maintained, special situations (sex, pregnancy, etc.) as well as other aspects of the disease, both functional and organic. All in all, an inclusive book, gradualist in tone and intelligent in its recommendations. Should be a pacemaker in the field.
