Microvascular Disease in Diabetes

 

Presents comprehensive coverage of the many microvascular complications of diabetes

Diabetes remains one of the main causes, in the western world, of legal blindness, end stage renal disease, and amputation, despite the implementation of tight glycemic control and the great progress in the management and care of our patients. This book provides a useful and handy tool to professionals and students in the field of diabetes and its microvascular complications by integrating information from clinical settings as well as from the frontlines of diabetic research. It provides readers with up-to-date diagnostic criteria, classifications, and therapeutic approaches. and recent discoveries on mechanisms of disease, experimental therapeutic agents, and biomarkers of disease. 

Written by top experts in the field, Microvascular Disease in Diabetes offers in-depth chapters covering pathophysiology; the genetics of diabetic microvascular disease; and the epigenetics of diabetic microvascular disease. It then provides sections featuring both clinical and research information on diabetic retinopathy, diabetic nephropathy, diabetic neuropathy, and diabetic foot. It also looks at coronary microvascular dysfunction and cerebral microvascular disease.

·         Integrates new and accessible material on diabetic microvascular comorbidities

·         Covers all relevant microvascular systems

·         Provides a much-needed resource synthesizing research and clinical applications to treating microvascular complications of diabetes

·         Presents current diagnostic criteria, classifications, and therapeutic approaches, as well as recent discoveries on the mechanisms of disease, experimental therapeutic agents, and biomarkers of disease

Assembled in an easily consultable manner, Microvascular Disease in Diabetes is an excellent text for investigators, clinicians, and students looking to improve their understanding of diabetic complications.
