Insights

C-reactive protein (CRP) elevation indicates increased carotid artery intima-media thickness (IMT) in ischemic stroke patients. Higher CRP levels correlate with worse functional outcomes and increased cardiovascular risk, necessitating intensive secondary prevention.

Area of Science:

  • Cardiovascular Medicine
  • Neurology
  • Biomarkers

Context:

  • Atherothrombotic ischemic stroke is a leading cause of disability.
  • Carotid artery intima-media thickness (IMT) is a marker of atherosclerosis.
  • C-reactive protein (CRP) is an inflammatory biomarker.

Purpose:

  • To investigate the relationship between CRP levels and carotid artery IMT in patients with atherothrombotic ischemic stroke.
  • To determine if CRP levels can predict IMT and functional outcomes.

Summary:

  • This study included 135 patients within 48 hours of ischemic stroke.
  • CRP levels and carotid ultrasonography were performed.
  • Patients were grouped by IMT tertiles, and CRP levels, functional disability, and vascular risk were analyzed.
  • A significant elevation of CRP was found across IMT groups (p<0.0008).

Impact:

  • CRP is a significant marker for increased IMT in atherothrombotic ischemic stroke.
  • A CRP cutoff of 1.5 mg/dL predicts greater IMT, worse functional disability, and higher cardiovascular risk.
  • Patients with CRP levels ≥1.5 mg/dL require more intensive secondary prevention strategies.

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

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)...
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.
Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...
