Insights

Carotid haemodynamic parameters, including resistive index (RI) and pulsatility index (PI), alongside intima-media thickness (IMT), are useful in estimating cerebral infarction risk in Type 2 diabetes patients.

Area of Science:

  • Vascular Medicine
  • Diabetology
  • Neurology

Background:

  • Type 2 diabetes is associated with an increased risk of cerebral infarction.
  • Early identification of at-risk individuals is crucial for preventative strategies.

Purpose of the Study:

  • To evaluate the utility of carotid haemodynamic parameters, specifically resistive index (RI) and pulsatility index (PI), in assessing cerebral infarction risk among Type 2 diabetic patients.
  • To determine if these parameters, along with intima-media thickness (IMT), can predict previous cerebral infarction.

Main Methods:

  • A cross-sectional study involving 382 Type 2 diabetic patients and 110 controls.
  • Ultrasonography was performed to measure common carotid artery intima-media thickness (IMT), resistive index (RI), and pulsatility index (PI).
  • Atherosclerosis risk was assessed using the SMART risk score for diabetic patients.

Main Results:

  • Diabetic patients exhibited higher IMT, RI, and PI values compared to controls.
  • Patients with a history of cerebral infarction had significantly elevated IMT, RI, and PI.
  • Both IMT and PI were identified as independent risk factors for cerebral infarction in Type 2 diabetes.

Conclusions:

  • Carotid haemodynamic parameters (RI, PI) and IMT are valuable tools for estimating the risk of previous cerebral infarction in Type 2 diabetic patients.
  • Further prospective studies are needed to confirm the predictive value of these parameters for future cerebral infarction events.

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

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...
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.
