Background: This study aims to investigate the relationship between polymorphism of adiponectin (ADIPOQ) gene SNPS+276 and the severity of coronary heart disease (CHD) and coronary artery disease (CAD). Methods: A total of 582 inpatients were enrolled and divided into Group CHD (342 cases) and the control group (CON, 240 cases), according to their angiographic results from June 2014 to April 2016 for the genotype (G/T) analysis of ADIPOQ SNPs+276 by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results: Group CHD: GG 110 (32%), GT 205 (59%), and TT27 (8%); Group CON: GG 36 (15%), GT 161 (67%), and TT 43 (18%) (P < .05). The frequency of allele G in group CHD was 62.1% and 48.5% in group CON (P < .05). The frequencies of genotype GG, GT, and TT were 67 (33.3%), 107 (53.2%), and 27 (13.5%), respectively, in the group with single vascular lesion, and 64 (45.4%), 53 (37.6%), and 24 (17%), respectively, in the group with multiple vascular lesions. There was statistical significance between the two groups (P < .05). Conclusions: The 276G gene of adiponectin may be a susceptibility gene of CHD, and the genotype GG may be related to the severity of this disease.

The Relationship

Aim. To study the relationship between the levels of synthesis of reactive oxygen species (ROS) by platelets and neutrophils in patients with coronary heart disease (CHD) before and after coronary artery bypass grafting (CABG), depending on sensitivity to acetylsalicylic acid (ASA).Material and methods. The study included 95 patients with coronary artery disease who are indicated for CABG surgery. The control group consisted of 30 healthy donors. The antiplatelet therapy was stopped for at least 5 days before CABG. In the postoperative period, from the first day, all patients were received 100 mg of an enteric form of acetylsalicylic acid (ASA). Resistance to ASA was determined at the level of platelet aggregation with arachidonic acid ≥20% by optical agregometry at least at one observation point: before CABG, on 1-3 day and on 8-10 day after surgery. We evaluated the spontaneous and induced lucigenin-dependent chemiluminescence (CL) of platelets (ADP induction) and neutrophils (zymosan induction) by the exit time to maximum intensity (Tmax), maximum intensity (Imax) and area (S) under the CL curve.Results. 70.5% sensitive (sASA) and 29.5% resistant (rASA) to ASA patients were revealed. Prior to CABG, in sASA patients, the Imax of spontaneous and zymosan-induced neutrophil CL and CL platelet activity was increased relative to control values. Tmax of spontaneous platelet CL, Imax and S under the ADP-induced platelet CL curve were lower in sASA patients, if to compare with rASA patients. On the 1st and 8-10th day after CABG in sASA patients, the CL indicators of neutrophil and platelet activity also remained elevated compared to control values. On the 1st day after CABG decreased levels of S under the spontaneous CL curve of neutrophils in rASA patients was established compared with sASA patients, and increased levels of Imax and S under the curve of induced neutrophil CL were detected in comparison with the control range. In rASA patients, the values of Tmax of spontaneous platelet CL decreased in relation to the values detected in the control group and sASA patients. On the 8–10th day after CABG, most indicators of spontaneous and zymosan-induced CL neutrophils in rASA patients were also increased compared to control values. In rASA patients a positive correlation of Imax-induced CL was found (r=0.83) on the 1st day after CABG and negative correlations of Tmax of spontaneous CL (r=- 0.75) and S under the curve induced CL (r=-0.70) on the 8-10th day were detected between platelets and neutrophils.Conclusion. In sASA patients with coronary heart disease before and after CABG, a high level of synthesis of superoxide radical by neutrophils and platelets was detected. The relationship between the levels of the synthesis of superoxide radical by neutrophils and platelets was found only after CABG in rASA patients. Increased synthesis of superoxide radical due to metabolic and regulatory relationships in neutrophils and platelets stimulates pro-inflammatory processes in coronary artery disease and determines the sensitivity of platelets to ASA.

Objective: To determine whether providing cholesterol results during a patient-physician office encounter would affect the process-of-care in patients with hypercholesterolemia. Methods: We used a randomized, parallel-group, control design to conduct the study. Thirty-five participants had a lipoprotein analysis performed using the L.D.X. cholesterol analyzer. Patients randomly assigned to the intervention group (n = 19) had their results provided to the physician during the office visit; the results of those in the control group (n = 16) were not made available to the physician. Each participant's medical record was reviewed to determine the physican's process-of-care with respect to cholesterol management. The indicators of the process-of-care for which we sought documentation included therapeutic interventions and the physician's assessment of risk for coronary heart disease. We used Fisher's exact test to determine statistical significance of the intervention. Descriptive analysis was also performed. Results: We were unable to detect a statistically significant difference in therapeutic interventions (p = 0.183). However, we did observe a statistically significant difference in the physician's assessment of risk for coronary heart disease (p = 0.0001). Conclusions: Our data suggest that providing a cholesterol test result during a patient-physician office encounter positively affects the process-of-care in patients with hypercholesterolemia. Future studies should include larger numbers of patients and longer follow-up periods.

Abstract Background Chronic infection by HIV evolves with a vascular inflammatory action causing endothelial dysfunction. The action of the virus as well as the side effects of antiretroviral drugs contributes to the progression of cardiovascular diseases. The study aimed to characterise the changes of the structure of the coronary wall and the thickening of the intima by Optical Coherence Tomography in HIV-infected patients with or without symptoms of coronary heart disease. Methods Fifty-two HIV-infected individuals had a mean age of 49.8±11.4 years. There were 75% men, diabetes 30,8%, hypertension 30,8%, smokers 34,62% and 7,7% with cholesterol levels ≥99 mg/dl. Control group included 120 non-HIV-infected controls with coronary heart disease. All the participants from HIV-group receive ART, 100% of participants had plasma HIV RNA &lt;20 copies/mL and 78,85% of them have symptoms of coronary artery disease. Results The average diffuse homogeneous thickening of the intima in patients with HIV was 0.67±0.24 mm, and 0.34±0.18 mm in control group, with normal values not exceeding 0.05 mm. There was impaired three-layer structure of coronary wall in 90,4% (47 of 52) HIV-infected participants and in 60% of control group, atherosclerotic plaque had only 34,62% of HIV group. All HIV-infected patients receive ART more than 5 years. Conclusion The coronary angiography and OCT demonstratedthat the inflammatory process resulting from HIV-infection or HAART may be relevant in the changes of coronary arteries in HIV-positive patients. The changes are predominantly represented by thickening of the intima, impaired three-layer structure of arterial wall and accelerating atherosclerosis.

Given the significant increase in the frequency of atrial fibrillation (AF) in elderly and senile patients with confirmed coronary heart disease (CHD), the study of the relationship between the polymorphisms responsible for the functioning of the renin-angiotensinaldosterone system and the presence of this disease becomes relevant. Purpose of the study. To study the genetic polymorphism of the CYP11B2 gene in elderly patients with ischemic heart disease, as well as to identify the role of aldosterone synthetase in the development of AF in this category of patients. Materials and methods. The study included 140 patients of both sexes (54,3% – men), over the age of 60 years, with confirmed coronary artery disease and any form of AF (the last episode no later than 12 months from the date of inclusion in the study). 84 patients agreed to participate in the study of aldosterone synthase polymorphisms. The control group consisted of 34 patients who had no diagnosed non-infectious diseases at the time of the survey. Both groups were comparable in age and sex characteristics. Results. Comparative evaluation of the distribution of genotypes and alleles – C344/T of the aldosterone synthase gene among patients with AF+CHD and relatively healthy individuals revealed that in the first group, most patients had the CYP11B2 T/T genotype in 38,1% of cases, the incidence was higher, than in patients of the comparison group – 14,7% (OR = 3.44, CI 1.07-11.07, p = 0.038). The frequency of detection of genotypes of CYP11B2 С/T and CYP11B2 С/С did not significantly differ in the compared groups. In the group with AF+CHD, the T allele was significantly more common (53,6% vs. 35,3%; p<0,05), while the frequency of occurrence of allele C was significantly higher in the group of relatively healthy individuals (64,3% vs. 47,1%; p<0,05). Conclusion. AF in elderly and senile patients with CHD is associated with the presence of CYP11B2 T/T genotype (OR = 3,44, DI 1,07–11,07, p = 0,038) and is not associated with myocardial echocardiographic parameters, including the size of left atrium.

Purpose: Analysis of the expression level of circulating microRNAs in the blood as diagnostic biomarkers for the early diagnosis of vascular calcification in coronary heart disease. 36 patients took part in the study, including 18 patients suffering from coronary heart disease and calcification (average age: 45.7±6.5) and 18 healthy patients who did not have calcification as a control group (average age: 59.6±8.2). Bioinformatic analysis of data from blood samples (microRNA profiles) obtained from the public database GEO (GSE28858) and PubMed (PMC4964495) was carried out. Analysis of the level of microRNA expression was done using the microarray method. Statistical analysis was performed using R methods and using J-express Pro algorithms. We found previously shown relation of two microRNAs that were statistically significantly changed in our analysis with calcification of the cardiovascular system, mir-199a-5p and mir-382. We concluded that patients with coronary artery disease have several differentially expressed microRNA markers that can affect calcification in different ways. The data provided may have a positive result for the cardiovascular diagnostic strategy and personalized medicine.

Background: This study aims to investigate the correlation between premature coronary heart disease (pCHD) and both serum homocysteine (Hcy) and hypersensitive C-reactive protein (hs-CRP). Methods: A total of 170 patients with pCHD were enrolled in this study from June 2014 to April 2016 (including 52 patients with stable angina pectoris [SAP], 70 patients with unstable angina pectoris [UAP], and 48 patients with acute myocardial infarction [AMI]), together with 105 healthy controls (CON) selected at the same period, to observe the changes of Hcy and hs-CRP in CHD patients and those with different types of CHD. Results: The levels of serum Hcy and hs-CRP in group pCHD were significantly higher than in group CON (P < .05). The levels of Hcy and hs-CRP in group AMI were significantly higher than in group UAP and group SAP (P < .05). The changes of serum Hcy and hs-CRP were significantly higher in patients with multi-vascular lesions and dual-vascular lesions than in those with single-vascular lesion (P < .05). Conclusion: The levels of serum Hcy and hs-CRP in CHD patients are positively correlated with the severity of CHD, which increase with the increase of lesion count. The combined detection of Hcy and hs-CRP can initially reflect the severity of coronary artery, thus better guiding treatment and predicting prognosis.

Chronic Coronary Heart Disease

To evaluate possibilities of aspirin-induced gastroduodenopathy treatment in the patients with chronic ischemic heart disease by means of applying the internal endogenous prostaglandins stimulant.  Material and methods. 340 patients suffering from chronic coronary heart disease and receiving a long-term acetylsalicylic acid (ASA) therapy were examined on the base of the cardiovascular care unit of The Nizhny Novgorod Regional Clinical Hospital named after N.A. Semaschko. There were evaluated frequency, nature and severity of the aspirin-induced gastroduodenopathy. The patients with coronary heart disease and aspirin-induced gastroduodenopathy were divided in two groups. In the first group of patients there was applied rebamipide therapy (in a single daily dose 300 mg) in combination with the proton pump inhibitor (PPI) — pantoprazole. In the second group there was applied only pantoprazole therapy. For the purpose of specification of AIG pathogenetic mechanisms development, all the examined chronic coronary heart disease cases were tested on the prostaglandin E2 (PGE2) level in blood serum before the therapy beginning and after the treatment. The control group was formed of chronic coronary heart disease patients showing no AIG evidence. Statistical processing of the received data was fulfilled with the program «Statistika 10.0». Results. AIG was registered in 15% out of 340 chronic coronary heart disease patients. According to the endoscopic examination erosive disease of the body and antrum prevailed among the patients. The PGE2 level in the blood serum was significantly lower (р = 0,00087) in these patients in comparison with the control group. In association with PPI and rebamipide mixed therapy, esophagogastroduodenoscopy results showed no pathological findings in gastrointestinal mucosa and statistically significant (р = 0,00067) blood serum PGE2 level growing in all the treated patients. As a result of exclusive PPI therapy there was marked positive dynamics in endoscopic view in 19 out of 25 patients and a tendency to normalization of PGE2 level in the blood serum. However, PGE2 level growing was insignificant. Conclusion. The presented research demonstrates the possibility of AIG treatment with the use of internal endogenous prostaglandins stimulant — rebamipide in complex with proton pump inhibitor PPI therapy.

This cluster randomized controlled trial aimed to investigate the effects of an intervention to teach resourcefulness on depression and coping style of patients with coronary heart disease (CHD). A convenience sample of 72 patients in community settings took part. Participants in the intervention group (n = 36) received an 8-week intervention based on the concept of resourcefulness, plus routine health education. Participants in the control group (n = 36) received routine health education only. After the intervention, participants in the intervention group had significantly higher scores on resourcefulness and coping styles, and lower scores on depression than those in the control group (both ps < .001). The findings suggest that a well-developed intervention to teach resourcefulness could help patients with CHD to be more resourceful, improve their level of depression, and choose more effective strategies to cope with stress.

Background Although many observational studies have shown an association between plasma homocysteine levels and cardiovascular diseases, controversy remains. In this study, we estimated the role of increased plasma homocysteine levels on the etiology of coronary heart disease and acute myocardial infarction. Methods A two-sample Mendelian randomization study on disease was conducted, i.e. “coronary heart disease” ( n = 184,305) and “acute myocardial infarction” ( n = 181,875). Nine single nucleotide polymorphisms, which were genome-wide significantly associated with plasma homocysteine levels in 57,644 subjects from the Coronary ARtery DIsease Genome wide Replication and Meta-analysis (CARDIoGRAM) plus The Coronary Artery Disease (C4D) Genetics (CARDIoGRAMplusC4D) consortium genome-wide association study and were known to be associated at p < 5×10–8, were used as an instrumental variable. Results None of the nine single nucleotide polymorphisms were associated with coronary heart disease or acute myocardial infarction ( p > 0.05 for all). Mendelian randomization analysis revealed no causal effects of plasma homocysteine levels, either on coronary heart disease (inverse variance weighted; odds ratio = 1.015, 95% confidence interval = 0.923–1.106, p = 0.752) or on acute myocardial infarction (inverse variance weighted; odds ratio = 1.037, 95% confidence interval = 0.932–1.142, p = 0.499). The results were consistent in sensitivity analyses using the weighted median and Mendelian randomization-Egger methods, and no directional pleiotropy ( p = 0.213 for coronary heart disease and p = 0.343 for acute myocardial infarction) was observed. Sensitivity analyses confirmed that plasma homocysteine levels were not significantly associated with coronary heart disease or acute myocardial infarction. Conclusions The findings from this Mendelian randomization study indicate no causal relationship between plasma homocysteine levels and coronary heart disease or acute myocardial infarction. Conflicting findings from observational studies might have resulted from residual confounding or reverse causation.
