A single nucleotide polymorphism (SNP) in the adiponectin gene, 45T/G, has been reported in relation to a number of metabolic disorders, including obesity, insulin resistance, and diabetes. However, previous studies on the association between this SNP and the presence of coronary artery disease (CAD) have been few, with no report from Iranian subjects. The present study set out to investigate the association between this SNP and CAD in an Iranian population. Among 464 patients (age: 18–75 years), recruited from individuals who underwent coronary angiography, 135 patients had less than 50% reduction of coronary artery diameter and were classified as the CAD- group and 329 patients had more than 50% reduction of coronary artery diameter and were classified as the CAD+ group. The last group was divided into single-vessel disease (n = 86), two-vessel disease (n = 111), and three-vessel disease (n = 132). Healthy subjects (n = 106) who did not have any history of heart diseases were also recruited as the control group. All subjects were genotyped for the 45T/G polymorphism using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. A significantly higher frequency of the TG genotype and G allele, which was paralleled by a lower frequency of the TT genotype and T allele, was observed in both CAD+ and CAD- patients when compared with the control group (p≤ 0.001). There was no significant difference in the genotype distribution and allele frequencies between CAD+ and CAD- patients, and also between different subgroups of patients based on the number of stenosed vessels (p> 0.05). Our findings indicate that the presence of the G allele at the position +45 of the adiponectin gene may be associated with the risk of CAD in our study population. While we found no significant difference in the genotype distribution and allele frequencies between patients with angiography+ and angiography, this may be because the 50% stenosis cut-off does not discriminate sufficiently between individuals with and without significant coronary disease.

BACKGROUND Coronary artery disease is multifactorial in origin. Coronary artery disease predisposition is attributed to genetic factors also. Many gene polymorphisms are implicated out of which paraoxonase 1 (PON 1) gene is an important one. The product of paraoxonase gene is paraoxonase enzyme which is seen in serum associated with high density lipoprotein (HDL). This enzyme is mainly synthesised by the liver. The protective effect of HDL is attributed to the presence of such enzymes on it. Gln to Arg polymorphism at position 192 confers a risk of developing atherosclerosis and coronary artery disease (CAD). This study is done to assess the genotype distribution of PON 1 gene in CAD patients compared to healthy controls in a population from Kerala. METHODS The case group consists of 100 angiographically proven CAD patients with no history of hypertension, diabetes mellitus, hepatic disease or smoking. The control group had 100 healthy controls from the general population. PON 1 gene was amplified by a polymerase chain reaction (PCR) technique already reported and restriction fragment length polymorphism by the restriction enzyme Alwl was done to assess the polymorphism. to assess the polymorphism. RESULTS In this study, the frequency of heterozygous genotype QR was 86 % in control and 76 % in cases. Though there was no significant difference in allele distribution of Q or R, RR genotype was significantly higher in the case group ( 2 = 8.82; p value = .012). With binary logistic regression model, adjusting for age and sex, RR genotype is independently associated with CHD. Adjusted odds ratio of RR was 5.24 with 95 % confidence interval (CI) 1.41 - 19.47 for developing CHD (p < 0.05). CONCLUSIONS The RR genotype is more frequently seen in CAD patients than in controls. The QR genotype is more frequent than QQ or RR in both cases and controls. KEYWORDS Coronary Artery Disease, Paraoxonase, Gene Polymorphism

Abstract Background Coronary Artery Disease (CAD) is a common form of heart disease that is considered a serious health problem in society. Atherosclerosis is widely recognized as a chronic inflammatory disease of the vessels and can lead to CAD and myocardial infarction. The aim of the present study was to investigate serum levels of connexin-37 and stromelysin-1 as significant biomarkers of CAD and their correlation with the extent of CAD. Methods and results Sixty CAD patients with one-vessel (1VD), two-vessel (2VD), and three-vessel (3VD) disease were enrolled in this study. For comparison with the results, 20 healthy control subjects were also included in this study. Serum concentrations of connexin-37 and stromelysin-1 were determined using commercial ELISA kits. Serum connexin-37 concentrations were not significantly different between the patient and control groups (p < 0.05). The analysis showed a statistically significant difference between subjects with one-vessel disease, subjects with two-vessel disease, and subjects with three-vessel disease. Serum Stromelysin-1 concentration was significantly higher in the patients than in the control group (p < 0.05). Conclusions The results of our study indicate that serum levels of stromelysin-1, but not connexin-37, may contribute to the prediction of the occurrence and progression of CAD.

Abstract SREBP cleavage-activating protein (SCAP) plays a vital role in the modulation of cholesterol homeostasis, and cholesterol dysregulation is tightly associated with coronary artery disease (CAD). To investigate the correlation of the genetic polymorphism of SCAP with CAD, we conducted a case-control study of 528 CAD patients (case group) and 483 age- and sex- matched subjects from whom CAD was excluded (control group). Three tagSNPs (rs147215799, rs17079634 and rs59586735) in SCAP gene were genotyped in all participants, the genotype and allele frequencies of which were compared between two groups to determine their associations with CAD. We found rs17079634 showed significant difference in genotype distribution between the case and control group (P=0.016). The difference was most prominent in a dominant model (TT vs. CT + CC, P=0.004). After adjustment for confounding factors, the difference remained statistically significant (OR =1.363, 95% confidence interval [CI]:1.022~1.818, P=0.035). Whereas no significant associations of the other two SNPs with CAD were observed (P=0.393 for rs147215799 and 0.303 for rs59586735, respectively）. We drew conclusion that the SCAP genetic polymorphism rs17079634 was associated with CAD.

Introduction: Coronary artery disease (CAD) is a main cause of mortality in kidney transplant (KT) patients. Preoperative cardiovascular risk assessment is a crucial step before clearance for KT. Hypothesis: We seek to compare long term outcomes in patients who underwent PCI prior to KT as compared to those who did not need PCI. Methods: We identified patients who underwent KT from January 2008 to November 2019 at our institution and had coronary catheterization prior to KT. Results: We included 272 patients, of whom 54 (19.9%) underwent percutaneous coronary intervention (PCI), while the remaining 218 patients did not need PCI. The median age in the PCI group was 57.4 (46.9 - 61.2) years, while it was 53.9 (44.6 - 61) years in the control group. Baseline characteristics including gender, race, hypertension, diabetes, smoking, and hyperlipidemia were comparable in both groups. The median time to KT was 2.4 (1 - 5) years in the PCI group vs. 1.2 (0.6 - 3.3) years in the control group (p=0.001). Among patients who underwent PCI, 51.1% had single-vessel disease and 40.4% had multi-vessel disease on the coronary angiograms as compared with 15.4% and 11.8% in the control group (p<0.001). The rate of acute kidney injury within 72 hours after the catheterization was 33.3% in PCI group vs. 14.13% in those who did not need PCI (p=0.01) after excluding dialysis patients. Overall, there was no difference in mortality in the PCI group compared to control group after 10 years of follow-up (p=0.416). In a subgroup analysis of patients who underwent cardiac catheterization within 2 years prior to transplant, there was still no significant difference in mortality between PCI (n=23) and control group (n=139) (p=0.451). The need for PCI after the initial cardiac catheterization was similar between the 2 groups after 10 years of follow-up (p=0.904). Conclusion: Patients with CAD can be safely treated with PCI prior to kidney transplant and have comparable outcomes as compared to those who do not require PCI.

Aim: Studies have evaluated the association of miRNA-423 C>A genotyping with the susceptibility to various diseases such cancers, atherosclerosis and inflammatory bowel disease but the results were contradictory. However, no studies have reported the association between miRNA-423 rs6505162 C>A polymorphism and susceptibility of coronary artery disease. MicroRNAs regulate expression of multiple genes involved in atherogenesis. Therefore, we investigated the association of microRNA-423C>T gene variations with susceptibility to coronary artery disease. Methodology: This study was conducted on 100 coronary artery disease patients and 117 matched healthy controls. The genotyping of the microRNA-423 rs6505162C>A was performed by using Amplification refractory mutation system PCR method (ARMS-PCR). Results: A significant difference was observed in the genotype distribution among the coronary artery disease cases and sex-matched healthy controls (P=0.048). The frequencies of all three genotypes CC, CA, AA reported in the patient’s samples were 55%, 41% and 4% and in the healthy controls samples were 55%, 41% and 4% respectively. Our findings showed that the microRNA-423 C>A variant was associated with an increased risk of coronary artery disease in codominant model (OR = 1.96, 95 % CI, 1.12-3.42; RR 1.35(1.05-1.75, p=0.017) of microRNA-423CA genotype and significant association in dominant model (OR 1.97, 95% CI (1.14-3.39), (CA+AA vs CC) and non-significant association for recessive model (OR=1.42, 95%CI=0.42-4.83, P=0.56, AA vs CC+CA).While, the A allele significantly increased the risk of coronary artery disease (OR =1.56, 95 % CI, 1.03-2.37; p=0.035) compared to C allele. Therefore, it was observed that more than 1.96, 1.97 and 1.56 fold increased risk of developing coronary artery disease. Conclusion: Our findings indicated that microRNA-423 CA genotype and A allele are associated with an increased susceptibility to Coronary artery disease.

Coronary artery disease (CAD) is a clinical manifestation resulting from a narrowing of epicardial coronary arteries that supply blood and oxygen to the heart. Coronary artery disease is mostcommonlydue to atherosclerotic occlusion of the coronary arteries.Fibroblast growth factor 23 (FGF23) is a circulating peptide hormone secreted by bone cells,regulating phosphate and vitamin D metabolism. Several recent observational studies reported an independent association of circulating FGF23 with several cardiovascular disease (CVD) risk factors including left ventricular hypertrophy and vascular dysfunction,CVD progression and incident clinical CVD eventsand mortality.Apolipoprotein A1 (ApoA1) is the primary protein associated with high-density lipoprotein (HDL) particles,and plays a central role in reverse cholesterol transport. HDL cholesterol (HDL-C) and ApoA1 concentrations are inverlassely related to the risk for coronary artery disease. To find the role of fibroblast growth factor-23 in coronary artery disease and its associationwith Apolipoprotein-A1.This ccross –sectionalstudyincluded 42 elective patients attending the cardiology unit and the results of those patients were compared with 40 healthy control group. Blood samples were obtained for measurements of (FGF-23,troponin I,Apo-A1,total creatine kinase activity,urea,creatinine and lipid profile).The obtained results showed that there was a significant difference in serum FGF-23 in coronary artery disease (367.52 ± 128.52 pg/ml) as compared with the control (165.41 ± 53.65 pg/ml) (p< 0.05). There was a significant differences in Apo-A1 in coronary artery disease (2.03±0.90 mg/ml) as compared with the control (1.49 ± 0.25 mg/ml) (P = 0.014).There was a significant difference in age between CAD (58.66±8.85) and control group (51.125 ± 11.71) (P<0.005).There was a significant difference in TG where control (99.50 ± 21.59) differ from CAD (142.05 ± 66.24) (P = 0.006).According to the results that were shown in the tables, we can be conclude that higher levels of FGF23 and Apo-A1 may be associated with complications and mortality of CAD beside its associating with atherosclerosis in the Iraqi patients.

Background: Ten-year all-cause death according to incomplete (IR) versus complete revascularization (CR) has not been fully investigated in patients with three-vessel disease (3VD) and/or left main coronary artery disease (LMCAD) undergoing percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG). Methods: The SYNTAX Extended Survival Study evaluated vital status up to 10 years in patients who were originally enrolled in the SYNTAX trial. In the present sub-study, outcomes of the CABG CR group were compared with the CABG IR, PCI CR, and PCI IR groups. In addition, in the PCI cohort, the residual SYNTAX score (rSS) was used to quantify the extent of IR and to assess its association with fatal late outcome. The rSS of 0 suggests CR, whereas a rSS>0 identifies degree of IR. Results: IR was more frequently observed in patients with PCI vs. CABG (56.6% vs. 36.8%) and more common in those with 3VD than LMCAD in both PCI (58.5% vs. 53.8%) and CABG arm (42.8% vs. 27.5%). Patients undergoing PCI with CR had no significant difference in 10-year all-cause death compared with those undergoing CABG (22.2% for PCI with CR vs. 24.3% for CABG with IR vs. 23.8% for CABG with CR). In contrast, those with PCI and IR had a significantly higher risk of all-cause death at 10 years compared with CABG and CR (33.5% vs. 23.7%; adjusted hazard ratio [aHR]:1.48; 95% confidence interval [CI]:1.15-1.91). When patients with PCI were stratified according to the rSS, those with a rSS≤8 had no significant difference in all-cause death at 10 years as the other terciles (22.2% for rSS=0 vs. 23.9% for rSS>0-4 vs. 28.9% for rSS>4-8), whereas a rSS> 8 had a significantly higher risk of 10-year all-cause death as compared with those undergoing PCI with CR (50.1% vs. 22.2%; aHR:3.40; 95% CI:2.13-5.43). Conclusions: IR is common after PCI, and the degree of incompleteness was associated with 10-year mortality. If it is unlikely that complete (or nearly complete; rSS<8) revascularization can be achieved with PCI in patients with 3VD, CABG should be considered.

Background Recently, the role of inflammation in coronary artery disease and the association of inflammatory biomarkers with adverse outcomes have been investigated in many studies. We investigated the relationship between high serum mobility group box 1 protein levels and established risk factors for coronary artery disease. Methods Fifty-five patients who presented to our Cardiovascular Surgery Clinic and subsequently underwent coronary artery bypass surgery for coronary artery disease and 50 healthy subjects presenting to the cardiology outpatient clinic without any cardiovascular problem were included in the study. The mean age was 61.47 ± 9.38 years for patients and 58.20 ± 10.15 years for controls. Results There was no statistically significant difference between groups with respect to age or sex. Family history of coronary artery disease, aspirin use, hypertension, and type 2 diabetes were significantly more prevalent in the patient group versus the control group. A significant difference was found between patients and healthy controls with respect to high mobility group box 1 protein levels ( p = 0.001). Conclusions Serum high mobility group box 1 protein was significantly increased in patients with coronary artery disease in comparison to healthy subjects. No associations were found between high mobility group box 1 protein level and certain risk factors for coronary artery disease.

Abstract Nitric oxide is synthesized from L-arginine by endothelial nitric oxide synthase encoded by eNOS gene. This study was performed to investigate the relationship between the serum nitric oxide level and eNOS gene polymorphism in the Turkish population with angiographically diagnosed coronary artery disease (63.47 ± 9.10 years old, n=250) and control subjects without any history and/or risk factors of coronary artery disease (60.71 ± 9.14 years old, n=150). Griess assay and PCR-RFLP analysis were used to measure the serum nitric oxide metabolites and genotypes, respectively. It was found that Glu/Glu, Glu/Asp and Asp/ Asp genotype frequencies of the eNOS were 49.3%, 41.3% and 9.3% respectively in the control group, and 45.6%, 41.2% and 13.2% in the patient group. Serum nitric oxide levels were (32.56 ± 17.26) μM in controls and (29.84 ± 11.88) μM in patients. Neither the frequencies of the Glu298Asp genotypes nor the serum nitric oxide levels showed a significant difference between the groups. There was also no correlation between serum nitric oxide levels and the frequencies of the eNOS genotypes. Result showed that the coronary artery disease of the Turkish population seemed to develop without any alterations in eNOS Glu298Asp genotype frequency and the serum nitric oxide level.
