This book consists of a collection of current reviews of clinical and experimental studies of hypertension by 25 leading clinicians and investigators in this field. The 35 manuscripts and the several sections of discussions, questions, and answers were collected as a result of a three-day symposium. The papers summarize well many aspects of the etiology, pathology, clinical course, and treatment of this disease. No effort is made to summarize the several studies or to outline classification and therapy. The bibliography affords excellent reference to many early and recent publications. The accumulated current studies and opinions of the essayists afford good orientation reading and stimulus for study to those investigating hypertension.
