ABSTRACT
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.

BACKGROUND AND AIM: The increasing number of coronary artery bypass grafting (CABG) is associated with a need for active introduction of methods improving immediate and long-term results of these interventions. Results of a number of studies conducted during recent years allow to consider high dose statin therapy one of such methods. In this article we present results of rosuvastatin administration to patients with ischemic heart disease (IHD) prior to surgery. METHODS: Rosuvastatin (40 mg/day) was given for 4 weeks before CABG to patients who had previously taken simvastatin (20 mg/day). RESULTS: This regimen was assocaed with reduction of desquamation of endothelium of the intima, reduction of the number of smooth muscle cells in the media, as well as the proliferation index according to the immunohistochemical analysis in sections of the great saphenous vein selected for the coronary anastomosis. CONCLUSION: It is assumed that the antiproliferative effects of high-dose rosuvastatin therapy may have a positive impact in relation to the viability of a remote arterio-venous grafts.

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 lisinoprillamlodipine combination. This combination was safe and had high antihypertensive activity. Practically all patients responded to therapy and achieved target level of arterial pressure.

ABSTRACT
Relationship between disorders of endothelial function, proinflammatory activity of leucocytes and effects of therapy with simvastatin or its combination with ezetimibe was studied in 72 patients with ischemic heart disease subjected to coronary artery bypass grafting (CABG). Vascular endothelial function was assessed by ultrasound detection of brachial artery response to its compression, oxidant activity of leucocytes - by chemiluminescent microscopy, severity of coronary artery atherosclerosis - by invasive coronary angiography. Twenty two healthy individuals comprised control group. Endothelial function, activity of leucocytes, and lipid levels were evaluated before and in 12 months after CABG. Patients with multivessel involvement revealed more complex disorders of endothelial function and higher levels of leucocytes activity compared to patients with single-vessel disease. CABG resulted in disappearance of anginal attacks and negative stress echo test during 1-year observation in 80.6% of patients. Patients with recurrent angina after CABG had more severe endothelial and leucocytes disorders. Combined lipid lowering therapy (simvastatin plus ezetimibe) compared to simvastatin alone demonstrated higher efficacy in terms of achievement of target lipid levels, improvement of endothelial function and leucocytes disorders.
