Insights

Cardio ankle vascular index (CAVI) can help diagnose blood stasis syndrome (BSS) in stroke patients. Combining CAVI with age improves diagnostic accuracy, offering a valuable clinical tool.

Area of Science:

  • Cardiovascular Medicine
  • Traditional Asian Medicine
  • Diagnostic Imaging

Background:

  • Blood stasis syndrome (BSS) is linked to atherosclerosis.
  • Cardio ankle vascular index (CAVI) estimates atherosclerosis extent.
  • Diagnostic utility of CAVI for BSS requires investigation.

Purpose of the Study:

  • To examine the diagnostic utility of CAVI in predicting BSS.
  • To evaluate CAVI's accuracy in diagnosing BSS in stroke patients.
  • To assess the combined diagnostic power of CAVI and age for BSS.

Main Methods:

  • Measured BSS scores and CAVI in 140 stroke patients.
  • Analyzed correlations between BSS, CAVI, age, and systolic blood pressure (SBP).
  • Utilized receiver operating characteristic (ROC) curve analysis for diagnostic accuracy.

Main Results:

  • BSS scores significantly correlated with CAVI, age, and SBP.
  • CAVI was a significant independent factor for BSS (OR 1.55, P=0.032).
  • Combined CAVI and age (AUC=0.759) showed superior diagnostic accuracy for BSS compared to CAVI (AUC=0.703) or age (AUC=0.692) alone.

Conclusions:

  • CAVI demonstrates moderate diagnostic accuracy for BSS in stroke patients.
  • Combining CAVI with age significantly enhances diagnostic accuracy for BSS.
  • CAVI and age together offer a promising objective tool for clinical BSS diagnosis.

Peripheral 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...

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...

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)...

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
