Abstract:
BACKGROUND: Carotid intima-media thickness (IMT) or the presence of carotid plaque has been reported to be related to coronary artery disease (CAD). We evaluated the relationship of the parameters of carotid ultrasonography (US) with the severity of the CAD. METHODS: From November, 2005 to November, 2006, the patients who underwent both coronary angiography and carotid US were enrolled in our study. The severity of CAD was defined by the number of diseased major coronary arteries with a percent diameter stenosis over 50. Four groups including Group 0, which has normal coronary arteries, were compared. The average and maximal IMT and the presence of plaque were used as the parameters of carotid US. RESULTS: The total number of patients was 90. Men had a greater severity of CAD (p=0.001). The average carotid IMTs were increased with the severity of CAD (Group 0, 0.67+/-0.11 mm; Group 1, 0.66+/-0.13 mm; Group 2, 0.68+/-0.08 mm; Group 3, 0.78+/-0.10 mm; p=0.001). The maximal carotid IMTs were also increased (Group 0, 0.88+/-0.16 mm; Group 1, 0.85+/-0.20 mm; Group 2, 0.89+/-0.13 mm; Group 3, 1.06+/-0.17 mm; p=0.000). Carotid plaques were also more frequently present with the increased severity of CAD (p=0.004). CONCLUSIONS: Increased carotid IMT and the presence of carotid plaque were related to the severity of CAD. Carotid ultrasonography is useful for evaluating the severity of CAD.
