Prevalence and risk factors associated with coronary artery disease in Iranian patients with peripheral artery disease. JOURNAL OF VASCULAR NURSING 2024; 42:154-158. [PMID: 39244326 DOI: 10.1016/j.jvn.2024.04.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 12/12/2023] [Accepted: 04/15/2024] [Indexed: 09/09/2024]
Abstract
INTRODUCTION It is well known that peripheral artery disease (PAD) and coronary artery disease (CAD) coexist and therefore, patients diagnosed with PAD have an increased chance of developing concomitant CAD. CAD-related complications could be a leading cause of postoperative mortality in individuals with PAD undergoing vascular surgery. We present a case series of 48 patients who underwent coronary angiography before vascular surgery and an updated review of previous reports to determine the prevalence of concomitant CAD in a convenience sample of Iranian patients. METHODS This cross-sectional study was performed on 48 patients with confirmed PAD admitted to Imam Ali Hospital, affiliated with the Kermanshah University of Medical Sciences (KUMS), Kermanshah Province, Iran. A vascular surgeon diagnosed PAD based on the patient's symptoms, Doppler ultrasound, and CT angiography (CTA). All patients underwent coronary angiography to determine if they also had CAD. We defined significant CAD as a ≥70% luminal diameter narrowing of a major epicardial artery or a ≥50% narrowing of the left main coronary artery. RESULTS Of 48 patients, 35 (72.9%) were male, 13 (27.1%) were female, and the mean age was 64.18±12.11 years (range, 30 to 100 years). The incidence of CAD in patients with PVD was 85.42% (41/48). The patients with CAD were more likely to be hypertensive than those without CAD (80.5 vs. 14.3, p-value<0.001). Of 41 patients with CAD, 9 (22.0%) had one-vessel disease, 10 (24.3%) had two-vessel disease, and 22 (53.7%) had three-vessel disease. CONCLUSION Hypertension was a significant risk factor for CAD. Patients with hypertension and multiple major coronary risk factors scheduled for PVD surgery should be carefully evaluated for concomitant CAD.

Shahsanaei F, Gharibzadeh A, Behrooj S, Abbaszadeh S, Nourmohammadi M. A systematic review and bioinformatic study on clinical, paraclinical, and genetic factors predisposing to stent restenosis following percutaneous coronary intervention. BMC Cardiovasc Disord 2024; 24:304. [PMID: 38877398 PMCID: PMC11177414 DOI: 10.1186/s12872-024-03955-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Accepted: 05/22/2024] [Indexed: 06/16/2024] Open
Abstract
BACKGROUND Stent restenosis is a relatively common phenomenon among patients with coronary heart disease undergoing percutaneous coronary intervention (PCI). It seems that a set of clinical, laboratory, and even genetic factors make people susceptible to such a phenomenon and in fact, this is multi-factorial. We aimed to first determine the underlying clinical and laboratory risk factors for the occurrence of stent re-stenosis after PCI based on a systematic review study, and after that, through a bioinformatics study, to evaluate the related genes and microRNAs with the occurrence of stent re-stenosis. MAIN TEXT In the first step, the manuscript databases including Medline, Web of Knowledge, Google Scholar, Scopus, and Cochrane were deeply searched by the two blinded investigators for all eligible studies based on the considered keywords to introduce clinical and laboratory determinants of stent re-stenosis. In the bioinformatic phase, and following a review of the literature to identify genes and microRNAs involved in restenosis, the interaction of each gene with other genes associated with stent re-stenosis was determined by GeneMANIA network analysis and Cytoscape software. Overall, 67 articles (including 40,789 patients) on clinical and biochemical predictors for stent restenosis and 25 articles on genetic determinants of this event were eligible for the final analysis. The predictors for this event were categorized into four subgroups patient-based parameters including traditional cardiovascular risk profiles, stent-based parameters including type and diametric characteristics of the stents used, coronary lesion-based parameters including several two target lesions and coronary involvement severity and laboratory-based parameters particularly related to activation of inflammatory processes. In the bioinformatic phase, we uncovered 42 genes that have been described to be involved in such a phenomenon considering a special position for genes encoding inflammatory cytokines. Also, 12 microRNAs have been pointed to be involved in targeting genes involved in stent re-stenosis. CONCLUSIONS The incidence of stent re-stenosis will be the result of a complex interaction of clinical risk factors, laboratory factors mostly related to the activation of inflammatory processes, and a complex network of gene-to-gene interactions.

Abstract
Background Coronary artery disease (CAD) is the most common reason for mortality and disability-adjusted life years (DALYs) lost globally. This study aimed to suggest a new gene list for the treatment of CAD by a systematic review of bioinformatics analyses of pharmacogenomics impacts of potential genes and variants. Methods PubMed search was filtered by the title including Coronary Artery Disease during 2020-2023. To find the genes with pharmacogenetic impact on the CAD, additional filtrations were considered according to the variant annotations. Protein-Protein Interactions (PPIs), Gene-miRNA Interactions (GMIs), Protein-Drug Interactions (PDIs), and variant annotation assessments (VAAs) performed by STRING-MODEL (ver. 12), Cytoscape (ver. 3.10), miRTargetLink.2., NetworkAnalyst (ver 0.3.0), and PharmGKB. Results Results revealed 5618 publications, 1290 papers were qualified, and finally, 650 papers were included. 4608 protein-coding genes were extracted, among them, 1432 unique genes were distinguished and 530 evidence-based repeated genes remained. 71 genes showed a pharmacogenetics-related variant annotation in at least (entirely 6331 annotations). Variant annotation assessment (VAA) showed 532 potential variants for the final report, and finally, the concluding PGs list represented 175 variants. Based on the function and MAF, 57 nonsynonymous variants of 29 Pharmacogenomics-related genes were associated with CAD. Conclusion Conclusively, evaluating circulating miR33a in individuals' plasma with CAD, and genotyping of rs2230806, rs2230808, rs2487032, rs12003906, rs2472507, rs2515629, and rs4149297 (ABCA1 variants) lead to precisely prescribing of well-known drugs. Also, the findings of this review can be used in both whole-genome sequencing (WGS) and whole-exome sequencing (WES) analysis in the prognosis and diagnosis of CAD.

Sex-specific associations of γ-glutamyltransferase to HDL-cholesterol ratio and the incident risk of cardiovascular disease: three Korean longitudinal cohorts from different regions. Front Endocrinol (Lausanne) 2023; 14:1231502. [PMID: 37649976 PMCID: PMC10464609 DOI: 10.3389/fendo.2023.1231502] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Accepted: 07/31/2023] [Indexed: 09/01/2023] Open
Abstract
Background The combination of gamma-glutamyl transferase (GGT) and high-density lipoprotein cholesterol (HDL-C) (GGT/HDL-C) is a novel noninsulin-based marker for assessing the risk of nonalcoholic fatty liver disease and type 2 diabetes mellitus. However, whether the GGT/HDL-C ratio is related to the risk of incident cardiovascular disease (CVD) risk is not well known. Therefore, we aimed to investigate the longitudinal effect of GGT/HDL-C ratio on incident CVD risk in three large cohorts of Korean men and women. Methods Data were assessed from 27,643 participants without CVD from the Korean Genome and Epidemiology Study (KoGES), Health Risk Assessment Study (HERAS), and Korea Health Insurance Review and Assessment (HIRA) (HERAS-HIRA) datasets. The participants were divided into four groups according to the GGT/HDL-C quartiles. We prospectively assessed hazard ratios (HRs) with 95% confidence intervals (CIs) for CVD using multivariate Cox proportional-hazard regression models over a 50-month period following the baseline survey. Results During the follow-up period, 949 patients (3.4%; 529 men and 420 women) developed CVD. The HRs of CVD for GGT/HDL-C quartiles 2-4 were 1.36 (95% CI, 0.91-2.02), 1.54 (95% CI, 1.05-2.26), and 1.66 (95% CI, 1.12-2.47) after adjusting for metabolic parameters in women, but GGT/HDL-C did not show a trend toward increases in incident CVD in men. Regional discrepancies were evident in the results; the increase in HR in the metropolitan hospital cohort was more pronounced than that in the urban cohort, and the risk was not increased in the rural cohort. Conclusion GGT/HDL-C ratio may be a useful predictive marker for CVD in women. Furthermore, the prevalence of CVD was strongly correlated with the GGT/HDL-C ratio in metropolitan areas, and this correlation was more significant than that observed with GGT or HDL-C in isolation.

Evaluating the use of novel atherogenicity indices and insulin resistance surrogate markers in predicting the risk of coronary artery disease: a case‒control investigation with comparison to traditional biomarkers. Lipids Health Dis 2022; 21:126. [DOI: 10.1186/s12944-022-01732-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 11/03/2022] [Indexed: 11/28/2022] Open
Abstract
Abstract
Background
Due to the contribution of coronary artery disease (CAD) to serious cardiovascular events, determining biomarkers that could robustly predict its risk would be of utmost importance. Thus, this research was designed to assess the value of traditional cardio-metabolic indices, and more novel atherogenicity indices and insulin resistance surrogate markers in the identification of individuals at risk of CAD.
Methods
A case‒control survey was conducted, in which 3085 individuals were enrolled. Their clinical and biochemical data were gathered at baseline. The investigated indices included the atherogenic index of plasma (AIP), triglyceride-glucose (TyG) index, TyG-body mass index (TyG-BMI), lipoprotein combine index (LCI), cholesterol index (CHOLINDEX), Castelli’s risk indices-I, II (CRI-I, CRI-II), and metabolic score for insulin resistance (METS − IR). To examine the relationship between these variables and CAD risk, multiple regression analyses adjusted for potential confounders were conducted.
Results
Overall, 774 angiographically confirmed CAD patients (mean age = 54 years) were compared with 3085 controls (mean age = 51 years). Higher triglyceride, total cholesterol and fasting blood sugar levels and lower HDL-C levels were related to an elevated risk of CAD (P-for-trend < 0.001), while the direct association between increased serum LDL-C concentrations and a greater risk of CAD only became apparent when excluding those with diabetes, and statin users. Among novel indices, greater values of the majority of these markers, including AIP, CRI-I, and -II, CHOLINDEX, LCI, and TyG-index, in comparison to the lower values, significantly elevated CAD risk (P-for-trend < 0.001).
Conclusion
According to the current findings, novel atherogenicity indices and insulin resistance surrogate markers, in particular, AIP, CRI-I and II, CHOLINDEX, LCI, and TyG-index, may be useful in predicting CAD risk.

PLoS One 2022; 17:e0250799.

Abstract
Carotid plaque is a subclinical measure of atherosclerosis. We have previously shown measures of carotid plaque to be heritable in a sample of 100 Dominican families and found evidence for linkage and association of common variants (CVs) on 7q36, 11p15, 14q32 and 15q23 with plaque presence. Our current study aimed to refine these regions further and identify rare variants (RVs) influencing plaque presence. Therefore, we performed targeted sequencing of the one LOD unit down region on 7q36, 11p15, 14q32 and 15q23 in 12 Dominican families with evidence for linkage to plaque presence. Gene-based RV analyses were performed using the Sequence Association Test for familial data (F-SKAT) under two filtering algorithms; 1. all exonic RVs and 2. non-synonymous RVs. Replication analyses were performed using a sample of 22 Dominican families and 556 unrelated Dominicans with Exome Array data. To identify additional non-synonymous RVs influencing plaque, we looked for co-segregation of RVs with plaque in each of the sequenced families. Our most strongly associated gene with evidence for replication was AMPD3 which showed suggestive association with plaque presence in the sequenced families (exonic RV p = 0.003, nonsynonymous RV p = 0.005) and replication families (exonic RV p = 0.04, nonsynonymous RV p = 0.02). Examination of the sequenced family pedigrees revealed two missense variants on chromosome 11 which co-segregated with plaque presence in one of our families; rs61751342 (located in DENND2B), and rs61760882 (located in RNF141). The rs61751342 missense variant is an eQTL for SCUBE2 in the atrial appendage. Notably, SCUBE2 encodes a protein which interacts with vascular endothelial growth factor (VEGF) receptor 2 to regulate VEGF-induced angiogenesis, thus providing biologic plausibility for this gene in atherosclerosis. In conclusion, using targeted sequencing of previously-identified linkage regions, we have identified suggestive evidence for the role of RVs in carotid plaque pathogenesis.

Abstract
Cardiac CT provides critical information for the evaluation of cardiovascular diseases. However, involuntary patient motion and physiological movement of the organs during CT scanning cause motion blur in the reconstructed CT images, degrading both cardiac CT image quality and its diagnostic value. In this paper, we propose and demonstrate an effective and efficient method for CT coronary angiography image quality grading via semi-automatic labeling and vessel tracking. These algorithms produce scores that accord with those of expert readers to within 0.85 points on a 5-point scale. We also train a neural network model to perform fully-automatic motion artifact grading. We demonstrate, using XCAT simulation tools to generate realistic phantom CT data, that supplementing clinical data with synthetic data improves the scoring performance of this network. With respect to ground truth scores assigned by expert operators, the mean square error of grading motion of the right coronary artery is reduced by 36% by synthetic data supplementation. This demonstrates that augmentation of clinical training data with realistically synthesized images can potentially reduce the number of clinical studies needed to train the network.

Abstract
AIM The gene encoding the vitamin D receptor (VDR) is considered in many studies to be a good candidate responsible for susceptibility to several diseases such as coronary artery disease (CAD). Epidemiological data show that cardiovascular disease is one of the major health problems in Polish society. Basic studies show that genetic factors play a significant role in the pathogenesis of CAD. We conducted this clinical study to determine if the VDR gene polymorphisms TaqI (rs731236), ApaI (rs7975232), and FokI (rs2228570) could predispose healthy individuals to an increased risk of premature CAD (P-CAD) incidents. METHODS We genotyped 845 subjects in a cohort consisting of 386 healthy volunteers with a documented P-CAD incident in their first-degree relatives and 459 healthy volunteers without family history (FH) of P-CAD. TaqI, ApaI, and FokI polymorphisms in VDR were genotyped using TaqMan assays and the endpoint genotyping method (qPCR). Statistical analyses were performed using the Power Analysis Software STATISTICA v.13.3. RESULTS Although no statistical significance was found for TaqI and ApaI genotype frequencies, the AA genotype of FokI polymorphism was significantly more frequent in the study group compared to the control group (24.61% vs. 16.99%). The results of logistic regression analysis suggested a significant association between FokI polymorphism and FH of P-CAD in heathy people under the recessive model (OR: 1.26 (1.07-1.49, p = 0.007)); however, the frequency of VDR haplotypes did not differ significantly between the control and study populations. CONCLUSIONS FokI polymorphism is may be associated with FH of P-CAD. FokI polymorphism may predispose to the development of P-CAD among healthy people over the next years.

Abstract
BACKGROUND Early-onset coronary artery disease (EOCAD) increases the risk of major cardiac adverse events (MACE) at the level of safety/effectiveness-related events. Since adverse events affect the quality of life of young patients with EOCAD, MACE prediction is of great importance for improving medical decision-making. AIMS OF THE STUDY We sought to determine whether the most important inflammation-related microRNAs in atherogenesis could predict MACE among patients with EOCAD. METHODS This nested case-control study recruited 143 young patients (males ≤45 and females ≤55 years old), selected from a cohort of patients with premature coronary atherosclerosis at a median follow-up period of 64.1 months. Total RNAs were extracted from their peripheral blood mononuclear cells. The expression levels of 18 miRNAs, which are involved in inflammation and atherogenesis, were analyzed via quantitative reverse transcription PCR. RESULTS A scoring model based on the upregulation of miR-146a_1 and miR-342_1, along with a history of myocardial infarction and the chronic usage of antithrombotic drugs, was able to predict MI/death at the level of safety-related events (higher vs lower risk scores: sHR: 4.61, 95% CI: 1.57-13.57, and p = 0.005). Another prediction model based on the downregulation of miR-145_1, age, and a history of unstable angina was also able to predict revascularization at the level of effectiveness-related events (higher vs lower risk scores: sHR: 2.90, 95% CI: 1.49-5.66, and p = 0.002). CONCLUSIONS Our results highlighted the role of miRNAs in adverse cardiac events and suggest that miR-146a_1, miR-342_1, and miR-145_1 may be useful biomarkers in predictive and preventive cardiology.

Salehi Ravesh M, Rusch R, Friedrich C, Teickner C, Berndt R, Haneya A, Cremer J, Pühler T. Impact of patients´ age on short and long-term outcome after carotid endarterectomy and simultaneous coronary artery bypass grafting. J Cardiothorac Surg 2019; 14:109. [PMID: 31202278 PMCID: PMC6570883 DOI: 10.1186/s13019-019-0928-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2019] [Accepted: 06/03/2019] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The purpose of this study was to investigate whether age has an effect on short and long-term outcome in patients who undergo simultaneous coronary artery bypass grafting (CABG) and carotid endarterectomy. METHODS From 2005 to 2017, 186 consecutive elective patients underwent CABG and synchronous endarterectomy at our institution. Patients were retrospectively classified according to age into 2 groups: patients above 70 years (elderly group: n = 97, 76.1 ± 3.9 years) and patients below 70 years (younger group: n = 89, 63.2 ± 4.8 years). RESULTS The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II, 4.4% vs. 2.5%; p < 0.001) and Society of Thoracic Surgeons (STS) score (0.7% vs. 1.6%; p < 0.001) were significantly higher in the elderly group. Otherwise, there was no difference between the two groups concerning important preoperative risk factors or the intraoperative data. Postoperatively, the incidence of temporary dialysis was significantly higher in the elderly group (14.4% vs. 3.4%; p = 0.009). The rate of tracheotomy (16.5% vs. 2.2%; p = 0.001), of re-intubation (7.9% vs. 18.6%; p = 0.033) and drainage loss (600 ml vs. 800 ml; p = 0.035) was significantly higher in this elderly group. Neurological complications and 30-day mortality were comparable. Long-term survival was satisfactory for both groups. Nevertheless, 5-year survival rates (63% vs. 85%) were significantly lower in the elderly group (p = 0.003). Logistic regression analysis identified chronic obstructive pulmonary disease (COPD) and arrhythmia as significant risk factors for 30-day-mortality, but not age. CONCLUSIONS CABG in combination with synchronous endarterectomy can also be performed with satisfactory results in elderly patients.

Abstract
BACKGROUND The prevalence of coronary artery disease (CAD) is increasing globally, supporting the need for the identification of novel biomarkers. Therefore in the present study, we have explored the association of SIL2A, SIL6R, STNFRI, STNFRII, and MMP9 in CAD patients. METHODS Twenty one patients with angiographically defined CAD with more than 50% occlusion, at least, in one coronary artery and twenty healthy subjects (n=20) without the history of cardiovascular symptoms were enrolled. Demographic and biochemical analysis (e.g. Total Cholesterol (TC), Triglyceride (TG), and HDL-C) were measured in all the subjects. The level of cytokines receptor (SIL2A, SIL6R, SIL6R, STNFRI, STNFRII, and matrix metallopeptidase 9 (MMP9) were evaluated. RESULTS Our results showed the higher level of MMP9 in patients group compared to the control subjects, while no significant differences were detected for other cytokines. In particular the level of MMP9 was significantly (P=.015) increased from 181.16 ng/mL (95%CI: 112.1-199.2) to 192.0 ng/mL (95%CI: 181.5-265.2). Moreover, the sensitivity and specificity of MMP9 were 95.45% and 45%, respectively, as detected by receiver operating characteristic (ROC) curves. CONCLUSION We demonstrate the significant correlation of MMP-9 with CAD with sensitivity of 95.45%, suggesting its role as a biomarker in CAD patients. Further studies in larger population - preferably multicenter setting - are warranted to explore the functional role of this marker in coronary artery disease.

The Effect of Chinese Herbal Medicine Gualouxiebaibanxia Decoction for the Treatment of Angina Pectoris: A Systematic Review. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2016; 2016:8565907. [PMID: 27777598 PMCID: PMC5061958 DOI: 10.1155/2016/8565907] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/03/2016] [Accepted: 08/08/2016] [Indexed: 12/20/2022]
Abstract
We systematically assess the current clinical evidence of Gualouxiebaibanxia (GLXBBX) decoction for the treatment of angina pectoris (AP). We included RCTs testing GLXBBX against conventional drugs and GLXBBX combined with conventional drugs versus conventional drugs. 19 RCTs involving 1730 patients were finally identified, and the methodological quality was evaluated as generally low. The results of the meta-analysis showed that GLXBBX alone had significant effect on improving angina symptoms (RR: 1.24, 95% CI 1.14 to 1.35; P < 0.00001), ECG (RR: 1.28 [1.13,1.44]; P < 0.0001), and HDL-C (MD: 0.56 [0.54,0.58]; P < 0.00001) compared with anti-arrhythmic drugs. A significant improvement in angina symptoms (RR: 1.17 [1.12,1.22]; P < 0.00001) and ECG (RR = 1.22; 95% CI = [1.14,1.30]; P < 0.00001) was observed for GLXBBX plus conventional drugs when compared with conventional drugs. Eight trials reported adverse events without serious adverse effects. GLXBBX appears to have beneficial effects on improvement of ECG and reduction of angina symptoms in participants with AP. However, the evidence remains weak due to the poor methodological quality of the included studies. More rigorous trials are needed to confirm the results.

Abstract
The worldwide cardiovascular disease (CVD) epidemic is of grave concern. A major role in the etiology of CVDs is played by the platelets (thrombocytes). Platelets are anuclear cell fragments circulating in the blood. Their primary function is to catalyze clot formation, limiting traumatic blood loss in the case of injury. The same process leads to thrombosis in the case of CVDs, which are commonly managed with antiplatelet therapy. Platelets also have other, nonhemostatic functions in wound healing, inflammation, and tissue regeneration. They play a role in the early stages of atherosclerosis and the spread of cancer through metastases. Much remains to be learned about the regulation of these diverse platelet functions under physiological and pathological conditions. Breakthroughs in this regard are expected to come from single platelet studies and systems approaches. The immobilization of platelets at surfaces is advantageous for developing such approaches, but platelets are activated when they come in contact with foreign surfaces. In this work, we develop and validate a protocol for immobilizing platelets on supported lipid bilayers without activation due to immobilization. Our protocol can therefore be used for studying platelets with a wide variety of surface-sensitive techniques.

Abstract
BACKGROUND After coronary stenting, the risk of developing restenosis is from 20 to 35 %. The aim of the present study is to investigate the association of genetic variation in candidate genes in patients diagnosed with restenosis in the Kazakh population. METHODS Four hundred fifty-nine patients were recruited to the study; 91 patients were also diagnosed with diabetes and were excluded from the sampling. DNA was extracted with the salting-out method. The patients were genotyped for 53 single-nucleotide polymorphisms. Genotyping was performed on the QuantStudio 12K Flex (Life Technologies). Differences in distribution of BMI score among different genotype groups were compared by analysis of variance (ANOVA). Also, statistical analysis was performed using R and PLINK v.1.07. Haplotype frequencies and LD measures were estimated by using the software Haploview 4.2. RESULTS A logistic regression analysis found a significant difference in restenosis rates for different genotypes. FGB (rs1800790) is significantly associated with restenosis after stenting (OR = 2.924, P = 2.3E-06, additive model) in the Kazakh population. CD14 (rs2569190) showed a significant association in the additive (OR = 0.08033, P = 2.11E-09) and dominant models (OR = 0.05359, P = 4.15E-11). NOS3 (rs1799983) was also highly associated with development of restenosis after stenting in additive (OR = 20.05, P = 2.74 E-12) and recessive models (OR = 22.24, P = 6.811E-10). CONCLUSIONS Our results indicate that FGB (rs1800790), CD14 (rs2569190), and NOS3 (rs1799983) SNPs could be genetic markers for development of restenosis in Kazakh population. Adjustment for potential confounder factor BMI gave almost the same results.

Abstract
BACKGROUND & OBJECTIVES An increase in prevalence of atherosclerosis has been noted worldwide with reports of higher incidence of atherosclerotic vascular changes in Asian Indians. There is a need to measure vascular atherosclerotic changes and provide objective parameter to predict cardiac and cerebrovascular adverse events. Atherosclerotic changes in carotids and coronaries are generally accepted as an association. We attempted in this study to relate intimal-luminal changes in carotid arteries to luminal changes in coronary arteries. Our study presents results of high resolution ultra sonographic (HRUS) evaluation of intimal-medial-thickness (IMT) in carotid with luminal changes in coronaries on multidetector-CT (MDCT) in clinically asymptomatic and symptomatic individuals. METHODS In this prospective study, HRUS examination of the carotid bifurcation was performed in 151 individuals to measure IMT in asymptomatic and symptomatic groups. Assessments of coronary arteries of the same group of patients were evaluated by MDCT within a week interval. IMT changes were associated with age, sex, predisposing factors, calcium burden of coronaries and structural atherosclerotic changes in coronary arteries. RESULTS A linear association of IMT was observed with increasing age. IMT of 0.5-0.69 mm was noted in 50 per cent of patients between 51-56 yr with higher number of symptomatic patients in this group. Linear increases in coronary vascular changes were noted with increasing IMT thickness. Changes were more prevalent in diabetic, hypertensive, treadmill test (TMT) positive and clinically symptomatic patients. INTERPRETATION & CONCLUSIONS Age-related progression of atherosclerosis was evident in internal carotid arteries. Significant association was observed in the IMT thickness of right common carotid (RCC) and coronary disease in symptomatic group; whereas IMT of left common carotid and internal carotid arteries did not show any association. RCC IMT between 0.5-0.7mm showed maximal association with significant symptomatic narrowing of coronary arteries. Patients with IMT beyond 0.7mm had no association with symptoms.

Abstract
Introduction In coronary artery disease (CAD), medical treatment is the main clinical strategy for controlling ischemia and angina symptoms while restoring a satisfactory level of usual activities and improving quality of life (QOL). This study's purpose was to evaluate in CAD patients the antianginal efficacy of 4‐month treatment with ivabradine plus a β‐blocker and to record patient compliance and the effect of treatment on QOL. Methods In this noninterventional study, 2403 patients with chronic stable angina were prospectively studied from 245 private cardiology offices. Data were recorded at baseline and at 1 and 4 months after inclusion. Patient quality of life was assessed using the EuroQol 5 dimensions (EQ‐5D) questionnaire. Results From baseline to study completion, mean heart rate decreased from 81.5 ± 9.7 bpm to 63.9 ± 6.0 bpm (P <‐0.001), mean number of anginal attacks decreased from 2.0 ± 2.0 times/wk to 0.2 ± 0.6 times/wk (P < 0.001) and nitroglycerin consumption decreased from 1.4 ± 2.0 times/wk to 0.1 ± 0.4 times/wk (P < 0.001). The percentage of patients with Canadian Cardiovascular Society angina class I increased from approximately 38% (baseline) to 84% (study completion; P < 0.001). The reduction in anginal attacks, nitroglycerin consumption, and angina score was correlated with reduction in heart rate (P < 0.001). The mean EQ‐5D visual analogue scale index increased by 16.1 points (P < 0.001), and compliance with treatment was high throughout the trial (96%). Conclusions Ivabradine administration on top of optimal individualized dose of β‐blockers is associated with decreased anginal events and with improvement of QOL in CAD patients.

Abstract
Background: Coronary Artery Disease (CAD) is the most common cause of death worldwide. MEF2A directly regulates target genes in the process of muscle development. This gene product is a transcription factor. MEF2A protein in homodimer or heterodimer forms binds to A/T-rich cis elements with conserved sequence in promoter, regulator, and enhancer of many genes, which are determining in evolution and development of skeletal, heart, and smooth muscle cells, especially endothelial cells. In fact, this protein maximizes the activity of these elements. Objectives: The two MEF2A gene polymorphisms that were proposed to have an association with CAD are rs34851361 (A/G) and rs325400 (T/G) SNPs. This study aimed to examine these associations. Patients and Methods: This study was a molecular case-control study. Blood samples were collected from 300 patients with CAD and 150 healthy people from Golestan and Imam Khomeini Hospitals, Ahvaz, Iran. In both groups, angiography had confirmed the presence or lack of stenosis. Association of rs34851361 and rs325400 with CAD was evaluated by PCR and then restriction fragment length polymorphism (RFLP) analysis was performed. Results: Chi square test showed no association between rs34851361 SNP and CAD (χ2 = 3.59, df = 2, and P = 0.16); however, there was an association between rs325400 SNP and CAD (χ2 = 24.77, df = 2, and P < 0.001). A/T haplotype showed association with CAD and G/G and G/T showed protective effect against CAD. Conclusions: The results of this study show that rs325400 polymorphism is in association with CAD; meanwhile, none of the rs34851361 genotypes was associated with CAD.

Abstract
OBJECTIVES Recent interest has developed in understanding the health effects attributable to different components of particulate matter. This review evaluates the effects of black carbon (BC) on cardiovascular disease in individuals with pre-existing disease using evidence from epidemiologic and experimental studies. METHODS A systematic literature search was conducted to identify epidemiologic and experimental studies examining the relationship between BC and cardiovascular health effects in humans with pre-existing diseases. Nineteen epidemiologic and six experimental studies were included. Risk of bias was evaluated for each study. RESULTS Evidence across studies suggested ambient BC is associated with changes in subclinical cardiovascular health effects in individuals with diabetes and coronary artery disease (CAD). Limited evidence demonstrated that chronic respiratory disease does not modify the effect of BC on cardiovascular health. CONCLUSIONS Results in these studies consistently demonstrated that diabetes is a risk factor for BC-related cardiovascular effects, including increased interleukin-6 and ECG parameters. Cardiovascular effects were associated with BC in individuals with CAD, but few comparisons to individuals without CAD were provided in the literature.
