Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

129
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Summary

High-intensity transient signals (HITS) detected by Transcranial Doppler (TCD) predict recurrent ischemic events in carotid artery dissections. This finding aids in identifying high-risk patients for proactive management.

Area of Science:

  • Neurology
  • Vascular Medicine
  • Diagnostic Imaging

Background:

  • Spontaneous Cervical Artery Dissections (CeAD) pose management challenges due to difficulties in identifying high-risk individuals.
  • Early prediction of recurrent ischemic events (IEs) following CeAD is crucial for timely intervention.

Purpose of the Study:

  • To evaluate the predictive value of high-intensity transient signals (HITS) detected by Transcranial Doppler (TCD) for recurrent ischemic events (IEs) in patients with CeAD.
  • To synthesize evidence from existing literature and a new cohort study.

Main Methods:

  • A systematic review and meta-analysis of studies on HITS in CeAD patients predicting IEs, adhering to PRISMA guidelines.
  • Data from five prior studies and a retrospective cohort of 34 CeAD patients were pooled.
  • Subgroup analysis examined the influence of dissected artery type (carotid vs. vertebral) on HITS predictive value.

Main Results:

  • Meta-analysis revealed HITS as a significant predictor of IEs (OR: 13.25, 95% CI [2.97-59.13]), with low heterogeneity (I2=42%).
  • HITS significantly predicted IEs in carotid artery dissections (p<0.01) but not vertebral artery dissections (p=0.11).
  • In the cohort, 20% experienced IEs, all with HITS; multivariable analysis identified HITS (p=0.006) and intra-luminal thrombosis (p=0.02) as significant predictors.

Conclusions:

  • HITS detected by TCD are a strong predictor of IEs in patients with carotid artery dissections.
  • TCD's clinical utility in identifying high-risk CeAD patients is highlighted.
  • Findings support the need for proactive management strategies in this subgroup to reduce future ischemic events.
