Opis

In an attempt to clarify the situation regarding the diagnosis, pathogenesis and therapeutics of cardiovascular dysfunction in diabetes, an International Symposium on Diabetic Heart was held in Tokyo, Japan during October, 1989. Thirty-two selected articles from the poster presentations, compiled in this book, have been grouped in four sections, namely (a) Evaluation of Cardiovascular Problems, (b) Interactions of Diabetes and Hypertension, (c) Pathophysiological Aspects of Cardiovascular Dysfunction in Diabetes, and (d) Pharmacological and Therapeutic Aspects of Diabetic Heart. It is hoped that the contents of these chapters will provide adequate information regarding the current status of cardiovascular abnormalities in diabetes and this book will be of great interest to both clinical and experimental cardiologists as well as endocrinologists interested in diabetes.
