Interrelationship of dyslipidemia with indicators of regional hemodynamics in patients with atherosclerosis of the visceral branches of the abdominal aorta

Introduction and aim - to determine the relationship of dyslipidemia and endothelial shear rate in the unpaired visceral arteries in patients with atherosclerosis in the abdominal aorta pool. Mathereals and methods. The study included 50 people. All patients were examined by a single protocol. Conduct a full clinical-laboratory and instrumental examination, supplemented by the following laboratory parameters: total cholesterol (TC), triglycerides, HDL, LDL, apolipoprotein A1, apolipoprotein B, Remnant cholesterol calculated using the formula: total cholesterol - (HDL+LDL). All patients underwent Doppler ultrasound unpaired branches of the abdominal aorta ultrasound scanner Voluson E6 (General Electric) was performed, Toshiba Aplio 500. Measurement of the shear rate (shear rate) is determined by the formula: SR=4xVpeak/Vd, Vpeak - peak flow rate visceral branches of the abdominal aorta, Vd - end-diastolic diameter of the visceral branches of the abdominal aorta. Results and discussion. The analysis of the various characteristics of the regional blood flow showed lower values of shear rate in the celiac trunk in patients with atherosclerosis of the visceral branches of the aorta. In the group of patients with abdominal aortic atherosclerosis pool demonstrated significantly lower levels of HDL, higher levels of VLDL, atherogenic factor, apolipoprotein B, triglycerides and Remnant cholesterol. Correlation analysis revealed an inverse association between the level of Remnant cholesterol and shear rate in the celiac trunk (r = -0.284, p = 0.04). Conclusions. The development of atherosclerosis in the celiac trunk and/or the superior mesenteric artery is associated with higher triglycerides, VLDL, Remnant cholesterol, apoliporoteinom B. In patients with atherosclerosis of visceral arteries decrease in endothelial shear rate in the celiac trunk was correlated with increased levels of Remnant cholesterol.
