Diabetic cardiovascular disease--AMP-activated protein kinase (AMPK) as a therapeutic target.
Cardiovascular complications are the leading cause of death and morbidity in patients with diabetes; accounting for around 7 out of 10 of all causes of death in this population. Returning patients to normoglycaemia alone has been shown to have little effect on cardiovascular end points, therefore new therapies and strategies are required in order to reduce the incidence and improve outcomes of cardiovascular disease in diabetic individuals. The metabolic enzyme AMP-activated protein kinase (AMPK) has emerged in recent years as an attractive potential therapeutic target for diabetic vascular disease, and studies have shown improved endothelial and smooth muscle cell function following AMPK activation. Additionally, improved lipid profiles, reduced hypertrophic cardiomyocyte growth and protection from cardiac ischaemia-reperfusion injury have also been observed as beneficial outcomes of AMPK therapy. In this review we will discuss in detail the potential downstream targets of AMPK activation in the cardiovascular system. We will also provide an overview of long-known and newly discovered direct and indirect AMPK activators, as well as novel synthesised AMPK-activating compounds, which will highlight the potential for further exploiting AMPK in a therapeutic context for cardiovascular disease in diabetes.
