Dr. Barnard's sanguine approach to the treatment of heart disease is implicit in the title -- in fact he has by no means given up on the potential of the transplant and it is his association with the procedure, along with his quite assured presence, which will lend appeal to what is no more than a minimal book. But interesting since he argues here, divagates there. Following a precis of what the heart is (no frail organ that) and does, he discusses atheroma at length (plaques via cholesterol collect in narrowing arteries which impair the flow of blood). Heredity predisposes; so does sex (women are less vulnerable); diet; stress has been overemphasized and ill-defined; cigarettes are an uncertain factor (though still lethal); exercise can be too stringent; obesity and diabetes have been less considered factors. He also goes into at some length the myocardial infarction and the urgency with which it should be handled. And there are a few words on earlier surgical techniques and the transplant for which he still retains hope. An attention-getter.
