Diabetic heart disease—Part II: The clinical and pathological spectrum

Abstract

Diabetes mellitus is a significant condition, affecting major segments of all population groups studied. With the introduction of insulin and oral hypoglycemic therapy, together with better understanding of diet and weight control gained over the past half century, the primary causes of diabetic morbidity and mortality have shifted in varying proportions from metabolic derangements, infection, and renal insufficiency to different types of cardiovascular disease. Despite extensive clinical and laboratory research on the etiology, pathogenesis, and even the existence of cardiovascular disease associated with diabetes mellitus, however, considerable debate is still apparent in this field. Our purpose is to present an overview of the subject of diabetic heart disease, with a critical analysis of epidemiologic, clinical, and pathological data. Some of this material will be addressed from the perspective of research in this area over the past decade by one of us (SMF), particularly in experimental hypertensive and diabetic cardiomyopathy. However, overall, an attempt will be made to provide an objective and balanced analysis in order to answer the question: does diabetic heart disease exist? Copyright © 1989 Wiley Periodicals, Inc.
