The development of atherosclerosis is closely related to the calcification of the vessel intima and fibrous plaques, being a complex and multifactorial process, in which the markers of bone formation and resorption play an important role. Objective. To study the biochemical markers of bone metabolism in men with stable coronary heart disease (CHD). Material and methods. The study included 102 men with verified CHD. Data were evaluated by densitometry, coronary angiography, multispiral computed tomography, color duplex scanning of brachiocephalic arteries, serum lipids (total cholesterol, triglycerides [TG], high-density [LHD] and low-density lipoprotein cholesterol), concentrationsin the blood of osteocalcin (OC), bone alkaline phosphatase (BAP), cathepsin K and C-telopeptides (CTx). Results. Concentrations of BAP, cathepsin K and CTx in patients with CHD were significantly higher than in men without CHD. The concentration of OC in men with normal bone mineral density was significantly lower than in patients with osteopenic syndrome. There was a direct correlation between OC and antiatherogenic HDL cholesterol and the inverse correlation between OC and TG, CTx and TG. There was no correlation between the level of bone remodeling markers and coronary artery (CA) lesion variant and the severity of coronary atherosclerosis on SYNTAX scale. The correlation analysis did not reveal the connection of biochemical markers of bone metabolism with the severity of coronary atherosclerosis and calcification and thickness of intima-media complex of carotid arteries. Absolute values of bone formation indices (BAP, OC) were significantly higher in patients with severe СA calcification than in patients without signs of calcification. Summary. Increased rates of osteogenesis and osteoresorption characterize the accelerated process of bone metabolism and indicate in favor of high rates of bone loss in men with CHD, which confirms the likelihood of common pathophysiological mechanisms of bone resorption and arterial calcification.

Abstract Aims Immune endothelial inflammation, underlie coronary heart disease (CHD) related phenotypes, could provide new insight into the pathobiology of the disease. We investigated DNA methylation level of the unique CpG island of HLA-G gene in CHD patients and evaluated the correlation with cardiac computed tomography angiography (CCTA) features. Methods Thirty-two patients that underwent CCTA for suspected CHD were enrolled for this study. Obstructive CHD group included fourteen patients, in which there was a stenosis greater than or equal to 50% in one or more of the major coronary arteries detected; whereas subjects with Calcium (Ca) Score=0, uninjured coronaries and with no obstructive CHD were considered as control subjects (Ctrls) (n=18). For both groups, DNA methylation profile of the whole 5'UTR-CpG island of HLA-G was measured. The plasma soluble HLA-G (sHLA-G) levels were detected in all subjects by specific ELISA assay. Statistical analysis was performed using R software. Results For the first time, our study reported that 1) a significant hypomethylation characterized three specific fragments (B, C and F) of the 5'UTR-CpG island (p=0.05) of HLA-G gene in CHD patients compared to Ctrl group; 2) hypomethylation level of one specific fragment positively correlated with coronary Ca score, a relevant parameter of CCTA (p<0.05) between two groups. Conclusions Our results showed that reduced levels of circulating HLA-G molecules could derive from epigenetic marks inducing hypomethylation of specific regions into 5'UTR-CpG island of HLA-G gene in CHD patients with obstructive coronary stenosis vs non critical stenosis group.

【Abstract】Objective: Toanalyze the efficacy of combined drug therapy for elderly patients with coronary heart disease and hypertension.METHODS:Sixty-six elderly patients with coronary heart disease and hypertension were enrolled from December 2017 to November 2018. They were randomly divided into two groups, 33 patients in each group. Patients in the experimental group received nifedipine. In combination with enalapril, patients enrolled in the control group received nifedipine monotherapy.RESULTS:Compared with the control group, the total effective rate, Serum Nitric Oxide (Serum NO) after treatment, CRP after treatment, HCY after treatment, and blood pressure after treatment were significantly improved (P<0.05). Serum NO and treatment before treatment in the 2 groups. There was no significant difference in pre-CRP, pre-treatment HCY, pre-treatment blood pressure, and adverse reactions during treatment (P>0.05).Conclusion: Theelderly patients with coronary heart disease and hypertension are treated with nifedipine and enalapril.
