To assess the prevalence of carotid artery (CA) atherosclerotic changes in patients with coronary artery disease (CAD).

48 patients (27 M and 21 F; mean age 64.6±11.7 years) with known or suspected CAD underwent ECG, EchoCG, cardiac Tc99m Sestamibi gated SPECT, interventional coronary arteriography (ICA), color Doppler investigation (CDUS) and 16-slice multidetector CT-angiography (MDCT) of extracranial vessels. By CDUS and MDCT the extent, size, type of carotid plaques were assessed. Plaques were classified as soft, intermediate, calcified.

A total 48 of patients had coronary arteries stenosis as detected with ICA. Stenosis were predominantly located in the proximal and mid-segments of the main coronary vessels. In 37(77%) patients presence of CA atherosclerotic plaques was detected. There was an excellent agreement between MDCT and CDUS in the detection of CA stenosis. The presence of carotid plaques and their extension was not correlated with the severity of coronary stenosis. The prevalence of calcified CA plaques was observed among patients with extent of coronary artery multivessel changes. A significant increase of common carotid artery intima-media thickness (IMT) was observed among patients with multivessel CAD-1.18±0.07mm.

CDUS study including carotid IMT measurenment and plaque evaluation may be a valuable tool in the screening of patients with CAD. MDCT appears as a useful noninvasive tool for the evaluation of carotid arteries. Complex use of CDUS and MDCT gives complete information about multifocal atherosclerotic changes in patients with CAD.
