Purpose Ultrasonographic contrast enhancement of carotid plaque (CECP) has been used
to detect neovascularization of vasa vasorum and plaque. However, it is uncertain whether
CECP can provide risk stratification of coronary artery disease (CAD). This study aimed to
evaluate the relationship between CECP and manifestations of acute coronary syndrome
(ACS) in established CAD patients and to explore the prognostic implication of CECP for
cardiovascular (CV) clinical outcomes. Methods A medical record review revealed that …

Purpose
Ultrasonographic contrast enhancement of carotid plaque (CECP) has been used to detect neovascularization of vasa vasorum and plaque. However, it is uncertain whether CECP can provide risk stratification of coronary artery disease (CAD). This study aimed to evaluate the relationship between CECP and manifestations of acute coronary syndrome (ACS) in established CAD patients and to explore the prognostic implication of CECP for cardiovascular (CV) clinical outcomes.
Methods
A medical record review revealed that contrast‐enhanced ultrasonography was performed to evaluate carotid atherosclerosis in 209 coronary artery‐stented and 105 non‐stented patients. The rate of ACS manifestations was compared depending on contrast uptake patterns: grade 0, absent; grade 1, dot; and grade 2, diffuse pattern. CV primary outcomes were assessed during a mean 7.6 months of follow‐up.
Results
Male sex, smoking, history of old myocardial infarction, intensive medications, and a favorable lipid profile were common in the stented versus non‐stented group. Patients with grade 2 CECP had a higher rate of ACS, greater plaque thickness, and class I‐II of Gray‐Weale plaque echogenicity. During follow‐up, 10 coronary revascularizations (nine ACSs), six strokes, and four heart failures occurred. Grade 2 CECP was more closely related with CV primary outcomes and showed a tendency toward more acute CV outcomes.
Conclusion
ACS manifestations were proportionate to CECP grade. Diffuse CECP uptake could be a risk factor for acute CV outcomes.
