Screening programs for hypertension.

MAJOR SCREENING PROGRAMS FOR HYPERTENSION ARE NECESSARY FOR THE FOLLOWING REASONS

(a) the 12 to 15% prevalence of hypertension in the North American population; (b) the high proportion of hypertensive patients who are inadequately treated or whose disease is not even recognized; (c) the fact that in too many medical centres hypertension is poorly investigated or considered an insignificant finding; (d) the demonstration by many groups, especially the Framingham study, of hypertension as the major factor in the occurrence of severe cardiovascular disease; and (e) the achievement of a marked decrease in severe cardiovascular complications following adequate treatment. But such screening programs are of little value if unaccompanied by a major educational effort directed not only to the public but also to the medical profession, and a parallel increase in the funding of biomedical research into the basic physiopathological mechanisms of hypertension.
