Dudko VA, Vorozhtsova IN, Sokolov AA, Volkova TG, Usov VIu, Shipulin VM. Kardiologiia 1993;33(6):14-6. In 26 patients with coronary heart disease, transesophageal atrial pacing was used to study cerebral hemodynamics from brain tomoscintigraphic findings as compared to the severity of induced of myocardial ischemia, echocardiographic parameters of left ventricular function and prostacyclin-thromboxane balance. In angina pectoris, the lower rate of cerebral blood flow was found to be correlated with the integral parameter of myocardial ischemia, deteriorated cardiac contractile and pump function, and higher plasma thromboxane A2 levels.
