Insights

Undiagnosed dysglycaemia (high blood glucose) is common in patients with cardiovascular disease, affecting nearly half of those with coronary artery disease. Inflammation levels correlate with blood glucose, highlighting a link between glucose metabolism and vascular complications.

Area of Science:

  • Cardiology
  • Endocrinology
  • Metabolic Disorders

Background:

  • Cardiovascular disease is linked to elevated glucose, but dysglycaemia prevalence in these conditions is unclear.
  • This study investigates unknown dysglycaemia and inflammation in Caucasian patients with ischaemic vascular complications.

Purpose of the Study:

  • To determine the prevalence of undiagnosed dysglycaemia (impaired fasting glycaemia, impaired glucose tolerance, or diabetes mellitus) in patients with coronary artery disease (CAD), cerebrovascular disease (CVD), and peripheral artery disease (PAD).
  • To examine the association between dysglycaemia and inflammatory markers in these patient groups.

Main Methods:

  • A case-controlled study involving 149 patients with CAD, PAD, or CVD and 59 healthy controls.
  • Dysglycaemia was assessed using a 75-g oral glucose tolerance test based on WHO/ADA criteria.
  • Fasting blood samples were analyzed for inflammatory parameters.

Main Results:

  • Dysglycaemia prevalence was significantly higher in patients (49% CAD, 55% CVD, 57% PAD) compared to controls (29%).
  • Odds ratios for dysglycaemia were elevated for CAD (1.7), CVD (1.9), and PAD (2.0).
  • Inflammatory markers were elevated in patient groups and increased with higher blood glucose levels; specific anti-inflammatory markers were reduced.

Conclusions:

  • Undiagnosed dysglycaemia is prevalent across different ischaemic cardiovascular manifestations.
  • A dose-dependent relationship exists between inflammation and glucose levels in patients with cardiovascular disease.

Type I Diabetes II: Pathophysiology

Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

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.

Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis

Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated hypertension...

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...
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...
