The trend of cardiology.

The study of cardiovascular disease has increased both in its scope and pace during the last decade. Included amongst the circumstances which have contributed to these changes are the recruitment to the specialty of younger workers on leaving the Fighting Services, the provision of greater facilities for research work, and the addition of newer instruments and equipment in the investigation of the several problems which await solution, while the application of surgery to the treatment of certain cardiovascular disorders has given a sharp incentive to the impatient as well as to the thoughtful therapist. The pages that follow will show how heavy has been the impact of such influences on orthodox clinical cardiology, and they should help opinion on the need to forego old views, or to form new ones, about cardiovascular disease. Here I only intend to touch on the changes which modern methods of investigation and therapy may bring about and to try and weigh their merits; it will be convenient to consider them under four headings.
