Association between glucagon and stroke in patients with type 2 diabetes

Area of Science:

• Endocrinology
• Neurology
• Metabolic Disorders

Background:

• Type 2 diabetes mellitus (T2DM) is a major risk factor for cerebrovascular disease.
• Glucagon, a hormone involved in glucose metabolism, has been implicated in various complications of diabetes.
• The specific role of fasting glucagon levels in the risk of stroke among T2DM patients requires further elucidation.

Purpose of the Study:

• To investigate the association between fasting glucagon levels and the risk of comorbid stroke in hospitalized patients with T2DM.
• To determine if this association differs between male and female patients.

Main Methods:

• A cohort of 1,745 hospitalized T2DM patients was analyzed.
• Patients were categorized into T2DM and T2DM with stroke groups.
• Fasting glucagon levels and clinical data were collected; binary logistic regression was used for analysis.

Main Results:

• In female T2DM patients, higher fasting glucagon levels were significantly associated with stroke.
• Multivariable analysis confirmed higher glucagon as an independent risk factor for stroke in women (OR = 2.396).
• No significant association was found between fasting glucagon and stroke risk in male T2DM patients.

Conclusions:

• Elevated fasting glucagon levels are independently associated with comorbid stroke in hospitalized female T2DM patients.
• This suggests a potential role for glucagon in the pathogenesis of cerebrovascular disease in this population.
• Further research is warranted to explore the clinical implications of these findings.
