Summary
A low ankle-brachial index (ABI) is strongly associated with cardiovascular (CV) risk in type 2 diabetes (T2DM) patients. Measuring ABI is a simple, noninvasive method for detecting subclinical atherosclerosis and predicting CV risk.
Area of Science:
- Cardiology
- Vascular Medicine
- Diabetology
Context:
- The ankle-brachial index (ABI) is a key diagnostic tool for peripheral artery disease and a cardiovascular (CV) risk marker.
- Type 2 diabetes (T2DM) patients are at increased risk for CV events.
- The association between a low ABI (< 0.9) and CV risk in T2DM requires further investigation.
Purpose:
- To investigate the association between a low ankle-brachial index (ABI) and cardiovascular (CV) risk in individuals with type 2 diabetes (T2DM).
Summary:
- A study of 253 T2DM patients found that a low ABI (< 0.9) was significantly associated with older age, higher coronary artery calcification (CAC), elevated total cholesterol, and increased total homocysteine.
- Low ABI independently predicted ischemic stroke and manifest CV diseases within 3 years in T2DM patients.
- ABI measurement is a simple, noninvasive, and cost-effective method for detecting subclinical atherosclerosis and enhancing CV risk prediction.
Impact:
- Highlights the clinical utility of ABI measurement in T2DM patients for early detection of atherosclerosis.
- Suggests that ABI can supplement existing methods for cardiovascular risk stratification in this population.
- Emphasizes the importance of considering ABI in the comprehensive assessment of T2DM patients' cardiovascular health.

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
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...
01:26Type 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...
01:24Type 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.
01:25Type 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...
01:23Assessment of blood pressure in brachial artery(two-step method)
Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...
