[Minor stenosis of carotid arteries: differential approach in diagnosis and surgical treatment].

The results of treatment of 161 patients with atherosclerotic small degree stenoses of carotid arteries (up to 50% of diameter) were analyzed. From them 67 patients underwent operations for chronic cerebro-vascular failure and 11 patients--for acute cerebro-vascular failure. 31 patients, who had contraindications for surgery or refused it, plasmapheresis procedures were carried on, 52 patients with asymptomatic carotid arteries' disease underwent conservative treatment. On the base of the results of examination and late results of treatment it is shown valid to recommend carotid endarterectomy as a prophylactic measure in acute cerebrovascular failure in asymptomatic patients who have morphologically unstable plaques of carotid arteries. If there are general contraindications for carotid endarterectomy, with the aim of prophylaxis of cerebrovascular failure the procedures of plasmapheresis for alteration of morphologic structure of plaques are advisable.

[A decrease in left ventricular hypertrophy and the dynamics of the parameters of circadian BP monitoring under the influence of ramipril in patients with essential arterial hypertension].

To evaluate factors of action of ramipril, an inhibitor of angiotensin-converting enzyme, which may induce a decrease in left ventricular hypertrophy (LVH), 45 LVH patients aged 21-53 years with mild and moderate essential hypertension have underwent echo-CG determination of left ventricular mass and 24-h monitoring of arterial pressure (AP). Multiple regression was used to examine prognostic significance of such parameters as age, sex, height, weight, duration of the disease, mean 24-h AP, its variability and the degree of nocturnal fall. It was found that ramipril reduced LVH irrespective of the hypotensive effect.

[The cerebral hemodynamics of patients with ischemic heart disease during transesophageal electrical stimulation of the left atrium].

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.
