abstract = {Background: The prevalence of carotid artery stenosis (CAS) in Chinese patients with angina pectoris is unknown.
Methods: The study population consisted of 989 consecutive patients who were scheduled to undergo nonemergent coronary angiography for suspicion of coronary artery disease (CAD) because of angina pectoris between January 2013 and December 2014. All patients underwent carotid ultrasonography to screen for CAS within one month before or after coronary angiography. We defined cases with 0–50%, 50%–70%, and >70% stenosis as mild, moderate, and severe stenosis, respectively.
Results: CAD was presented in 853 patients (86.2%) of whom 191 patients (19.3%) had 1-vessel disease, 246 patients (24.9%) had 2-vessel disease and 416 patients (42.1%) had 3-vessel disease; left main trunk stenosis present in 137 patients (13.9%). In carotid ultrasonography, the prevalence of mild, moderate, and severe stenosis as well as that of total occlusion of the carotid artery was 54.5%, 13%, 4.7% and 0.8%, respectively. Significant CAS (>50% stenosis and total occlusion) was present in 10.3%, 13.9%, 19.9% and 22.8% of patients with 0-vessel, 1-vessel, 2-vessel and 3-vessel CAD. The severity of CAS was directly correlated (r=0.194, P},
