In the first two chapters of this small volume, the author presents his views on the value of the ballistocardiogram, pulse records, and heart sounds in diagnosis, prognosis, and treatment. The last chapter deals with the controversial subject of the relationship of exogenous cholesterol and cigarette smoking to coronary artery disease. The author is positive in his belief that the increasing incidence of coronary artery disease in this country, particularly in the younger age groups, is to a large extent due to a diet high in cholesterol. As to smoking, he states, "The enormous rise in consumption of cigarettes explains in part why coronary disease kills men at an earlier age in 1955 than it did before 1900." Long years of experience as a teacher, research worker, and lecturer have enabled Dr. Dock to present his views in a convincing manner, even though many cardiologists will disagree with him.
