glycemic legacy effect
Persistent benefits of early good glucose control that continue despite later deterioration in glycemic control.
Full Definition
The glycemic legacy effect, also known as metabolic memory, refers to the phenomenon whereby the beneficial effects of early intensive glycemic control on diabetic complications persist for years or decades, even after glycemic control deteriorates or becomes similar between previously different treatment groups. This effect was first demonstrated in the DCCT/EDIC studies in type 1 diabetes and later confirmed in type 2 diabetes trials, suggesting that there are critical early periods in diabetes progression where achieving good glucose control provides long-lasting protection against vascular complications through epigenetic and structural changes in target tissues.
Usage
Usage note: Synonymous with metabolic memory; both terms are acceptable in clinical literature.
