Purpose Patients undergoing Coronary Artery Bypass Grafting (CABG) are at an increased risk of stroke or transient ischemic attack (TIA), mainly due to underlying carotid artery disease, particularly soft carotid plaques. Plaques in the carotid arteries can become unstable, potentially leading to embolic events and stroke when they get ruptured. Ulcerated and soft plaque are considered the most common types of plaque, which may lead to cerebral events. In some cases, echolucent plaques may also be misdiagnosed by traditional Ultrasound. Ultrasound...
Read more Methods and materials A number of thirty-four patients with carotid plaque were recruited (n=17 CABG and n=17 controls). All participants underwent standard carotid ultrasound following the national protocol, which includes the Common Carotid artery, Internal Carotid artery, External Carotid artery and vertebral arteries bilaterally; the traditional Ultrasound assessment was followed by 2D-SWE to assess plaque stiffness. A high-resolution Acuson Redwood ultrasound system (Siemens Healthineers) equipped with 2D-SWE capability and a high-frequency linear-array transducer was used to obtain optimal imaging at the area of...
Read more Results Ultrasound 2D-SWE measurements of 53 carotid plaques (n=26 CABG and n=27 controls) were obtained. Ultrasound 2D-SWE of carotid plaques ranges from 1.27 – 6.40 m/s. Carotid plaques in patients for CABG were found to be significantly softer than plaques in controls (mean difference, -1.22 m/s, 95% Confidence Interval -1.90 - -0.55, p = 0.001).
Read more Conclusion This study found that carotid plaques in patients undergoing Coronary artery bypass graft were significantly softer than those in control groups, as measured by ultrasound 2D-SWE. This result highlights the potential of 2D-SWE as a noninvasive tool for assessing plaque stability in high-risk CABG patients. This result could also indicate that patients presenting for a Carotid artery traditional Ultrasound assessment who have a growing soft plaque may benefit from preventing further heart disease in the future. Further studies with larger...
