[Prospective analysis of lipid profile parameters and markers of vascular inflammatory response with prognosis of undesirable coronary events in patients with coronary heart disease after angioplasty with stenting.]

The study of the causes of the development of vascular coronary complications after angioplasty with stenting using the evaluation of biochemical parameters in the dynamic observation of patients with IHD with significant coronary stenosis determines the relevance of the study. To analyze the parameters of lipid spectrum and markers of vascular inflammatory reaction in patients with IHD, in groups with stable angina and episode of unstable angina after angioplasty with stenting, to trace the dynamics of biochemical parameters and to reveal the predictors of undesirable coronary events. Patients with IHD with significant coronary stenosis of the arteries (SCS, n = 95) after coronary angiography at the point of maximum increase in the level of markers of the inflammatory reaction (3 months after angioplasty) are divided into 2 groups - patients with persistent stable angina pectoris (SA, n = 77) until the end of the study and patients with developed postvascularization episode of unstable angina (UA, n = 18). The dynamics of observation of biochemical parameters recorded the absence of normalization of the atherogenic spectrum of the lipid profile and the prolonged nature of the vascular inflammatory response to the end point of observation after angioplasty.The method of binary logistic regression revealed that in the general group of patients with IHD, an increase in the level of low density lipoprotein cholesterol by 1 mmol / L significantly increases the probability of significant coronary stenosis in men and raises the risk of UA after angioplasty by 7.38 times. It was found that patients with UA at the initial stage have a significantly higher risk of coronary blood flow instability in the post-vascularization period due to an elevated level of homocysteine. A set of biochemical markers for predicting the significance of coronary stenosis and development of undesirable vascular coronary events after angioplasty in patients with IHD has been identified: male sex, elevated LDL cholesterol and hyperhomocysteinemia.
