Summary
Abnormal glucose metabolism is common in vascular surgery patients, with 55% having dysglycaemia. Routine oral glucose tolerance tests (OGTTs) are recommended for early detection of undiagnosed diabetes and impaired glucose tolerance.
Area of Science:
- Endocrinology
- Vascular Surgery
- Metabolic Disorders
Background:
- Pathologic glucose metabolism affects up to 60% of acute coronary syndrome patients, with many undiagnosed.
- Vascular surgery patients represent a population at risk for glucose metabolism abnormalities.
Purpose of the Study:
- To determine the prevalence of abnormal glucose metabolism in vascular surgery patients.
- To assess the utility of oral glucose tolerance tests (OGTTs) in this population.
Main Methods:
- A prospective study of 276 vascular surgery patients who underwent OGTT.
- Categorization of glucose metabolism into diabetes mellitus, impaired glucose tolerance (IGT), impaired fasting glucose (IFG), and normal.
- Collection of data on vascular bed and medical history.
Main Results:
- The prevalence of dysglycaemia was 55% (29% diabetes, 24% IGT, 8% IFG).
- 44% of patients had previously unknown pathological glucose metabolism.
- Fasting glucose alone correctly diagnosed only half of the patients with diabetes.
Conclusions:
- Dysglycaemia prevalence in vascular surgery patients mirrors that in acute coronary syndromes.
- OGTT is crucial for identifying undiagnosed glucose metabolism issues in this group.
- Routine OGTT in non-diabetic vascular surgery patients is recommended for early diagnosis and potential outcome improvement.

01:22Complications 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,...
01:27Diabetic 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...
01:22Diabetes 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...
01:26Hypoglycemia
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...

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
01:29Hyperglycemia
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...
