Structural Constriction of the Artery Wall Contributes to Stenosis Severity in Unstable Angina

Eight consecutive patients with unstable angina underwent intravascular ultrasound imaging of the culprit artery with measurements recorded at the stenosis and at an adjacent reference site. In all patients, total artery cross-sectional area was smaller at the stenosis site than at the reference sit...

Description
Summary:Eight consecutive patients with unstable angina underwent intravascular ultrasound imaging of the culprit artery with measurements recorded at the stenosis and at an adjacent reference site. In all patients, total artery cross-sectional area was smaller at the stenosis site than at the reference site, indicating that a structural change in the artery wall due to a constrictive process appears to contribute to the worsening of stenosis severity associated with unstable angina.
