Background: In patients with acute ischemic stroke, current guidelines recommend maintaining blood glucose levels in a range of 140-180 mg/dL and closely monitoring to prevent hypoglycemia (<60 mg/dL). We aimed to assess glucose variability by continuous glucose monitoring (CGM) and to demonstrate the risk of acute ischemic stroke patients with glucose levels outside of the glucose management recommendations.

Methods: Patients with ischemic stroke admitted within 7 days after onset were prospectively enrolled, and their blood glucose levels were monitored every 15 minutes for 72-hour period using the FreeStyle Libre Pro. Read More

Hyperglycemia on hospital admission is a common phenomenon in acute ischemic stroke patients and represents an independent predictor of poor clinical outcome with or without acute recanalization therapies (systemic thrombolysis or mechanical thrombectomy). Effective restoration of normoglycemia is considered to be beneficial, but conclusive evidence from randomized controlled clinical trials and specific recommendations are lacking. In addition, aggressive glucose control can be complicated by hypoglycemia leading to early neurological deterioration. Read More

In the outpatient setting, glucagon-like peptide-1 (GLP-1) receptor agonists have proved to be highly efficacious drugs that provide glycaemic control with a low risk of hypoglycaemia. These characteristics make GLP-1 receptor agonists attractive agents to treat dysglycaemia in perioperative or high-dependency hospital settings, where glycaemic variability and hyperglycaemia are associated with poor prognosis. GLP-1 also has a direct action on the myocardium and vasculature-which may be advantageous in the immediate aftermath of a vascular insult. Read More

A growing body of evidences indicates the role of increased glucose variability (GV) as an independent cardiovascular risk factor in diabetes. It has been shown that high GV is associated with coronary and carotid atherosclerosis in diabetic subjects. The impact of enhanced glycemic fluctuations on vascular wall is mediated through non-enzymatic glycation, oxidative stress, activation of inflammatory pathways, and endothelial dysfunction.

Rationale Post-stroke hyperglycemia occurs in up to 50% of patients presenting with acute ischemic stroke. It reduces the efficacy of thrombolysis, increases infarct size, and worsens clinical outcomes. Insulin-based therapies have generally not been beneficial in treating post-stroke hyperglycemia as they are difficult to implement, may cause hypoglycaemia, possibly increase mortality and worsen clinical outcomes.

Diabetes increases the risk of cardiovascular diseases, which are the leading cause of mortality among diabetic patients. Although hyperglycemia is a major determinant of macrovascular and microvascular complications in diabetes, hypoglycemia and glycemic variability have also a strong influence on the cardiovascular system. This overview presents the current state of knowledge on the impact of type 2 diabetes on the cardiovascular system and new therapeutic strategies that have been recently developed to correct gluco-metabolic disturbances in patients with high cardiovascular risk, such as glucagon-like peptide-1 (GLP-1) receptor agonists, dipeptidyl peptidase-4 (DPP-4) inhibitors and sodium-glucose cotransporter 2 (SGLT2) inhibitors.

Owing to the worldwide increase in life expectancy, the high incidence of diabetes in older individuals and the improved survival of people with diabetes, about one-third of all individuals with diabetes are now older than 65 years. Evidence is accumulating that type 2 diabetes is associated with cognitive impairment, dementia and frailty. Older people with diabetes have significantly more comorbidities, such as myocardial infarction, stroke, peripheral arterial disease and renal impairment, compared with those without diabetes.

Diabetes is a significant health problem worldwide, and its association with cardiovascular disease (CVD) was reported in several studies. Hyperglycemia and insulin resistance seen in diabetes and prediabetes lead to an increase in reactive oxygen species, which triggers intracellular molecular signaling. The resulting prothrombotic state and increase in inflammatory mediators expedite atherosclerotic changes and the development of macrovascular complications. Read More
