Insights

Hypoglycaemia (low blood sugar) significantly increases cardiovascular risk in diabetes patients. It contributes to heart attacks, stroke, and mortality through inflammation, atherosclerosis, and cardiac issues.

Area of Science:

  • Cardiology
  • Endocrinology
  • Diabetology

Background:

  • Hypoglycaemia is linked to increased cardiovascular (CV) risk and mortality in diabetes.
  • Mechanistic links between hypoglycaemia and CV risk are not well-defined.
  • This review synthesizes data on how hypoglycaemia impacts CV risk in diabetic patients.

Purpose of the Study:

  • To review and summarize available data on the relationship between hypoglycaemia and cardiovascular risk in patients with diabetes.
  • To elucidate the mechanistic pathways through which hypoglycaemia may affect cardiovascular outcomes.

Main Methods:

  • Systematic review of mechanistic and clinical studies.
  • Compilation of study outcomes from relevant articles.
  • Discussion of factors contributing to hypoglycaemia-mediated cardiovascular disease (CVD).

Main Results:

  • Six recent trials highlight the importance of the hypoglycaemia-CV system link.
  • 88 studies indicate hypoglycaemia mechanistically increases CV risk.
  • Mechanisms include increased thrombotic tendency, abnormal cardiac repolarization, inflammation, and atherosclerosis.

Conclusions:

  • Emerging data confirm hypoglycaemia impacts CV function.
  • The mechanistic link between hypoglycaemia and CV complications is multifactorial.
  • Further research is needed to fully understand the impact of hypoglycaemia on the CV system.

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...
Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...
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...

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...
Type II Diabetes II: Pathophysiology01:24

Type II Diabetes II: Pathophysiology

PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
