To investigate the prevalence of high-risk carotid disease in patients presenting for routine echocardiography who have no known history of vascular disease. Methods. Males aged 40-65 years and females aged 50-65 years referred for routine echocardiography underwent carotid Doppler imaging. Patients were excluded from carotid imaging if they had any prior vascular history such as angina, myocardial infarction, stroke, TIA, PCI, CABG, peripheral arterial disease, previous peripheral vascular surgery or peripheral angioplasty. Patients were also excluded if they were >65 years of age. 80 consecutive patients were recruited during the study period. Two images were performed of each carotid, one of the common carotid artery (CCA) and one of the carotid bulb and the internal carotid artery. CCA maximal intimal medial thickness (IMT) was measured in the far wall of the CCA using an automated edge detection system. All measurements were performed offline using commercially available software. The presence of carotid plaque was defined using the atherosclerosis risk in communities (ARIC) definition. Patients were considered to be high-risk from a vascular standpoint if they had either carotid plaque or a CCA IMT ≥1.20mm. Results. See Table 1. Five patients were recommended to undergo formal carotid imaging because of the visual appearance of a severe stenosis of their internal carotid artery. Conclusions. Of 80 consecutive patients between the ages of 40 and 65 years referred for routine echocardiography, 54% had high-risk carotid disease. This observation emphasizes the high prevalence of carotid disease in patients presenting to our echocardiographic laboratory for cardiac imaging. Our observation suggests that while such a patient is in the ECHO laboratory the opportunity to gather important prognostic information regarding vascular health should not be overlooked.
