The cardiologist's responsibility for preventing coronary heart disease.
The recent increase in coronary heart disease is real  and the causes must mainly be environmental. Consequently the condition should largely be preventable. The application of what is already known is likely to be a far more effective way of reducing the mortality rate than all attempts at palliative treatment, but vigorous action will be necessary. Much greater sums are being expended  on coronary-care units and cardiac surgery than in preventing the need for them, although there is little evidence that they have significantly lowered the over-all mortality rate. Conventional treatment is immensely expensive. Prevention could in the long run be much cheaper. Cardiologists on their own are unlikely to succeed in a program of prevention. They need the help of many others, including community nurses, nutritionists, public health workers, sociologists, and of course general practitioners, but they have responsibility for leadership and for providing background knowledge. For the detection of certain risk factors, health examinations are necessary and should be part of general practice. Also, advice is best given on an individual basis. The chief-known risk factors (hyperlipidemia, hypertension, smoking, physical inactivity) could be controlled. CHD occurs in adults but atherosclerosis starts many years before. Prevention should begin with appropriate infant feeding, whenever possible with breast milk, and continue into childhood, when habits are formed and attitudes to life can best be influenced. It should be possible to bring up children virtually free from risk factors. It may never be possible to prove the effectiveness of such a multifactorial program by prospective controlled intervention studies, but the evidence indicates strong probability. The stakes are too high to delay action any longer. Physicians daily give advice in areas where the evidence is much less certain. Such a program for the control of coronary artery disease is urgently needed and could become one of the most rewarding activities for the medical profession.
