[Integral tests of the hemostasis system in assessing the efficiency of acetylsalicylic acid in patients with ischemic heart disease]

Despite the fact that acetylsalicylic acid (ASA) is the "gold" standard for the prevention of cardiovascular complications in patients with coronary heart disease (CAD), a number of patients still have risks of atherothrombosis. In the present study, the antithrombotic effect of ASA in patients with CAD was assessed in platelet-rich plasma (PRP) using integral tests of the hemostasis study: the T-TAS system (Total Thrombus-formation Analysis System) and the thrombin generation test (TGT). The study involved 34 patients with stable CAD (11 women, 23 men) and people (15 women, 18 men) in the control group. As a result of assessing the activity of thrombus formation using the T-TAS system, a significant decrease in the area under the curve (AUC10) was found in the group with CAD patients compared with the control (135.6 [88.0-222.3] and 260.5 [217.3-301.9], respectively, p.

[The Antihypertensive Effect of the Fixed Combination of Amlodipine and Lisinopril in Patients With Coronary Heart Disease After Coronary Artery Bypass Grafting]

Literature data and results of our own register have indicate that hypertension is one of the most common risk factor in patients with ischemic heart disease (IHD) who have undergone coronary artery bypass grafting (CABG). But despite proven benefits of control of hypertension after CABG adherence of patients to corresponding recommendations remains low. Fixed combinations of antihypertensive drugs are associated with better compliance. In 30 IHD patients after CABG we studied effects of fixed lisinopril/amlodipine combination. This combination was safe and had high antihypertensive activity. Practically all patients responded to therapy and achieved target level of arterial pressure.

[Study of the role of adrenergic vasoconstriction in the development of dynamic coronary obstruction in patients with stress-induced stenocardia]

The aim of the present investigation was to evaluate sympathetic vasoconstrictor influence and to define its role in the formation of coronary occlusion in patients with effort angina. The investigation covered 22 patients with Functional Class II-III stable effort angina. To detect vasoconstrictor responses on exercise and to identify their adrenergic component, pair bicycle tests were performed before and after administration of nitroglycerin and pratsiol. Repeated bicycle tests were conducted twice a day: at 10-11 a.m. and at 3-4 p.m. to study spontaneous exercise tolerance variations confirming the presence of dynamic coronary occlusion. The examinations indicated that in 18 patients the exercise resulted in functional major artery narrowing, aggravating the organic stenosis. Activation of smooth muscle alpha-adrenoreceptors is of a definite significance in the genesis of dynamic coronary occlusion in 50% of all the examinees.
