The Role of Diabetes and SGLT2 Inhibitors in Cerebrovascular Diseases.

PURPOSE OF REVIEW

Diabetes is a well-established risk factor for stroke. Understanding the pathophysiology of this connection is crucial to implementing appropriate prevention strategies. Lately, there has been a paradigm shift in the care of individuals with diabetes toward the use of glucose-lowering medications with potential cardiovascular, cerebrovascular or cardiorenal benefits. The aim of this article is to provide a critical analysis of the role of diabetes in cerebrovascular disease and current evidence and recommendations for the use of glucose-lowering medication with particular focus on the sodium glucose cotransporter-2 inhibitor (SGLT2i) class.

RECENT FINDINGS

Intensive glycemic control in individuals with diabetes reduces the risk of microvascular complications, but there is less clear evidence for decreasing risk of macrovascular events (e.g., stroke). A multifaceted management of diabetes addressing healthy lifestyle practices, glycemic control, and optimization of other cardiovascular risk factors is highly recommended. SGLT2i are the latest class of antihyperglycemic agents available for diabetes management. Canagliflozin and empagliflozin are associated with reduction in major adverse cardiovascular events (MACE). Dapagliflozin did not reduce the rate of MACE but is associated with reduction in heart-failure related death and hospitalization and has the potential to decrease dementia risk. Ertugliflozin decreases rates of hospitalization related to heart failure however it was non-inferior to placebo in reducing MACE. There is increasing evidence that the use of SGLT2i may reduce the risk of stroke, particularly hemorrhagic stroke, in individuals with type 2 diabetes and a high risk of cardiovascular events, and that SGLT2i may also be beneficial for brain health by decreasing risk of cognitive decline and dementia. Antihyperglycemic therapy should be tailored to patients' circumstances. SGLT2i treatment should be considered in patients with type 2 diabetes and established or high-risk cardiovascular disease, heart failure, or chronic kidney disease, to reduce the overall cerebro-cardiovascular and renal risks.
