This book opens with a brief foreword by Henry Christian, in which he states, "Dr. Ayman has had an extensive experience with hypertensive patients, whom he has subjected to long continued, thorough, clinical study in the homes of the patients, in the out-patient clinic, and in the wards of a hospital, before, after and when undergoing various forms of treatment, including sympathectomy..." This evidence of the author's qualifications to write on the subject of arterial hypertension becomes more and more impressive as the book is read. Dr. Ayman is writing from first hand information, from personal observations of hypertensive patients under a variety of conditions, and he interprets the results of his studies in an unbiased, objective manner.
Although this work is largely the result of the author's careful studies of a large number of cases, treated in a variety of ways, he is thoroughly familiar with the vast literature
