Feasibility and Applicability of Wireless Handheld Ultrasound Measurement of Carotid Intima-Media Thickness in Patients with Cardiac Symptoms

ABSTRACT

0.9 between all observers). Receiver operating characteristic curve analysis showed that the predictive power for CAD was improved when max-CIMT and plaque information (plaque≥2) was added [area under the curve (AUC) 0.838] to the traditional clinical CV risk factors (AUC 0.769). The cutoff values for CAD prediction with the standard device and the WHUS device were 1.05 mm (AUC 0.807, sensitivity 0.78, specificity 0.53) and 1.10 mm (AUC 0.725, sensitivity 0.98, specificity 0.27), respectively.CONCLUSION: max-CIMT measured by a WHUS device showed excellent agreement and repeatability, compared with standard ultrasound. Combined max-CIMT and plaque information added predictive power to the traditional clinical CV risk factors in detecting high-risk CAD patients.
