Insights

Diabetes significantly increases ischaemic stroke risk. Managing blood sugar (hyperglycaemia) in acute stroke patients is challenging but may improve outcomes, though research is ongoing.

Area of Science:

  • Neurology
  • Endocrinology
  • Cardiovascular Medicine

Background:

  • Diabetes mellitus is a major risk factor for ischaemic stroke, more than doubling risk.
  • Hyperglycaemia is prevalent in acute ischaemic stroke patients, even those without diagnosed diabetes.
  • Admission hyperglycaemia correlates with poorer functional outcomes post-stroke.

Purpose of the Study:

  • To explore the link between diabetes, hyperglycaemia, and ischaemic stroke.
  • To discuss the implications of managing hyperglycaemia in acute ischaemic stroke.
  • To review the current understanding and ongoing research into glucose-lowering therapies for stroke.

Main Methods:

  • Review of existing literature on diabetes, stroke, and hyperglycaemia.
  • Analysis of the association between admission glucose levels and stroke outcomes.
  • Discussion of challenges and potential benefits of glucose-lowering interventions.

Main Results:

  • Individuals with diabetes have a significantly elevated risk of ischaemic stroke.
  • Hyperglycaemia upon admission is linked to worse outcomes in acute ischaemic stroke.
  • The efficacy of early glucose-lowering treatment in acute stroke remains uncertain.

Conclusions:

  • Multifactorial risk factor management, including lifestyle, hypertension, and dyslipidaemia, is crucial for stroke prevention in diabetics.
  • Achieving normoglycaemia in acute stroke is difficult and carries risks like hypoglycaemia.
  • Further research, including Phase 3 trials, is needed to determine the role of glucose-lowering therapy in acute ischaemic stroke.

Complications of Diabetes Mellitus01:22

Complications of Diabetes Mellitus

Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia due to insulin deficiency, resistance, or both. Prolonged hyperglycemia disrupts metabolic homeostasis and leads to acute and chronic complications.Acute ComplicationsAcute complications result from sudden metabolic imbalance.Diabetic ketoacidosis (DKA) mainly appears in type 1 diabetes but may also develop in type 2 diabetes, particularly under extreme stress. It arises from severe insulin deficiency,...
Hyperglycemia01:29

Hyperglycemia

Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...
Diabetic Retinopathy01:27

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Hypoglycemia01:26

Hypoglycemia

Hypoglycemia is a blood glucose level below 70 mg/dL. It commonly occurs in individuals using insulin or insulin-secreting drugs, but may also arise in non-diabetic conditions. People with type 1 diabetes are at the highest risk because they depend on exogenous insulin. People with type 2 diabetes are also at risk, especially when treated with insulin or medications such as sulfonylureas, which increase insulin release regardless of blood glucose levels. It develops when insulin levels exceed...
Ischemic Stroke l: Introduction01:15

Ischemic Stroke l: Introduction

Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is based on...
