Summary

<p><strong>Aim.</strong> To assess a risk of vascular embolism in patients with ischemic heart disease (IHD) and hemodynamic insignificant asymptomatic carotid stenosis.</p><p><strong>Material and methods.</strong> 100 patients with IHD were examined. Ultrasound scanning of the main cranial arteries and transcranial Dopplerography was performed in all patients as well as lipid spectrum, fibrinogen level and blood D-diameter concentration were evaluated.</p><p><strong>Results.</strong> 165 carotid atherosclerotic plaques (AP) were detected in patients with IHD independently on angina severity. In IHD patients with nonhomogeneous hypoechogenic AP microembolic signals (MES) were revealed in 44,78%, with nonhomogeneous hyperechogenic AP - in 25%, with homogeneous hypoechogenic AP - in 4,16% of patients. MES were not recorded in patients with homogeneous hyperechogenic AP. There were not relations between MES and parameters of lipid spectrum as well as fibrinogen and Ddiameter plasma levels.</p><p><strong>Conclusion.</strong> Thus, during transcranial dopplerographic monitoring MES were recorded in the third part (27,9%) of IHD patients with hemodynamically insignificant carotid arteries stenosis. MES were predominantly observed in patients with nonhomogeneous AP especially with hypoechogenic components.</p>
