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.

Background: Coronary Artery Disease (CAD) is a major cause of mortality in most countries. Many risk factors such as high blood pressure, hyperlipidemia, diabetes, age, sex, obesity, smoking, and family history play a role in CAD. The aim of this study was to evaluate the concentration of Total Sialic Acid (TSA) and Lipid Profiles (LP) with the Severity of the Vessel in patients with non-smoker and diabetic CAD, so that by measuring these parameters, effective help for diagnosis and prevention for healthy people Prone to CAD, and also control the treatment of patients. Methods: In this study, 200 individual including 160 patient and 40 control group were considered. All patient groups were non-smokers and diabetic. Patients were divided into 4 groups according to the results of angiography: Patients with Normal angiography (n = 40) with one eclipse (n = 40), patients with double stenosis (n = 40) and patients with eclipse Three vessels (n = 40). The control group was chosen from people who had no history of CAD and other diseases. The lipid profile was measured by standard methods and serum total sialic acid was measured by ELISA method. Results: There was no significant difference between the two groups in age and sex, but there was a significant difference in family history (p<0.05). There was a significant difference in serum glucose level between the patient and the control group (p<0.05), Also hs-CRP serum levels were normal in two patient and control groups. Serum levels of cholesterol, triglyceride and LDL in patient group were significantly higher than that of the control group but HDL serum level was adverse (p <0.05), Also TSA serum level in the patient group was significantly higher than the control group (p<0.05). Conclusion: Serum Total Sialic Acid level in non-smoker and diabetic CAD patients has a significant increase compared to the control group. It seems that the above biochemical parameters contribute significantly to the development and progression of atherosclerosis and CAD, by which timely measurements of these parameters in healthy individual probably can be helpful in preventing and improving CAD and controlling the treatment of patients.

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.

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.

Background: Osteoprotegerin and osteopontin have recently emerged as key factors in both vascular remodelling and atherosclerosis progression. Interleukin-6 (IL-6) is an inflammatory cytokine with a key role in atherosclerosis. The relationship of osteoprotegerin, osteopontin, and IL-6 serum levels with endothelial function and arterial stiffness was evaluated in patients with coronary artery disease (CAD). Methods: We enrolled 219 patients with stable CAD and 112 control subjects. Osteoprotegerin, osteopontin and IL-6 serum levels were measured using an ELISA assay. Endothelial function was evaluated by flow-mediated dilation (FMD) in the brachial artery and carotid-femoral pulse wave velocity (PWV) was measured as an index of aortic stiffness. Results: There was no significant difference between control subjects and CAD patients according to age and sex. Compared with control subjects, CAD patients had significantly impaired FMD (p<0.001) and increased PWV (p=0.009). CAD patients also had significantly higher levels of osteoprotegerin (p<0.001), osteopontin (p<0.001) and IL-6 (p=0.03), compared with control subjects. Moreover, IL-6 levels were correlated with osteoprotegerin (r=0.17, p=0.01) and osteopontin (r=0.30, p<0.001) levels. FMD was correlated with osteoprotegerin levels independent of possible confounders [b coefficient= - 0.79, 95% CI (-1.54, -0.05), p=0.04]. Conclusion: CAD patients have increased osteoprotegerin, osteopontin and IL-6 levels. Moreover, there is a consistent association between osteoprotegerin and osteopontin serum levels, vascular function and inflammation in CAD patients. These findings suggest another possible mechanism linking osteoprotegerin and osteopontin serum levels with CAD progression through arterial wall stiffening and inflammation.

Abstract Coronary Artery Disease (CAD) is a chronic inflammatory disease caused by atherosclerosis and arteries become clogged due to plaque formation, fat accumulation, and various sorts of immune cells. IL-32 is a new proinflammatory cytokine, which enhances inflammation through inducing different inflammatory cytokines. The purpose of current research was to assess IL-32 serum levels in coronary artery disease subjects and its relationship with serum levels of IL-6 and TNF-α. Forty-two subjects diagnosed with CAD and thirty-nine control subjects were enrolled in the research. Serum levels of IL-6, TNF-α, and IL-32 were measured using the enzyme-linked immunosorbent assay (ELISA). IL-32, TNF-α, and IL-6 serum levels were significantly higher by 2.7, 3.48, and 3.2-fold in the CAD subjects than in control subjects, respectively. Moreover, no significant difference was found in TNF-α, IL-6 and IL-32 serum levels with the clogged arteries number in the CAD group. TNF-α and IL-32 serum levels in the CAD subjects with cardiac arterial stenosis in one major vessel were significantly increased than CAD subjects with cardiac arterial stenosis in more than one major vessels. ROC curve analysis revealed that serum levels of IL-32, TNF-α, and IL-6 showed good abilities in predicting CAD. Also, Multiple logistic regression analyses suggested that TNF-α, IL-6, and IL-32, serum levels of LDL and ox-LDL were independently related to the presence of CAD, while HDL serum levels were not. TNF-α, IL-32, and IL-6 showed an increase in CAD group and serum levels of these cytokines showed good abilities in predicting CAD. Our data suggested the involvement of TNF-α and IL-32 in the early stage of CAD.

Objective: The objective of this study was to investigate the association between proinflammatory cytokines in special, the interleukin-6 (IL-6), and insulin-like growth factor (IGF-1) levels in coronary artery disease (CAD) and type 2 diabetes mellitus (T2DM).Methods: This study was conducted from November 2017 to March 2018 in Anbar, Iraq. We studied a total of 90 individuals (46 men and 44 women) aged between 20 and 87 years. The samples were divided into four groups: CAD patients (n=23), T2DM patients (n=23), coronary artery disease and type 2 diabetes together in the same patient (n=23), and control group (n=21). The concentrations of IL-6 and IGF-1 were determined using a commercially available enzyme-linked immune sorbent assay.Results: The results of the present study showed that there were elevated serum levels of IL-6 and low levels of IGF-1 in all the tested groups, compared with the control. The difference was statistically significant at p<0.05. The results showed a positively correlated between IL-6 and IGF-1 in the CAD group and T2DM group, while it was a negative correlation between serum levels of IL-6 and IGF-1 in the T2DM+CAD group.Conclusion: Elevated levels serum of IL-6 predicts the development of CAD and T2DM. These data support a possible role for inflammation in diabetogenesis and complication of the cardiovascular disease. There is an inverse relationship between the levels serum of IGF-1 and increased risk of CAD and development of T2DM.

Objective Complement C1q tumor necrosis factor-related proteins (CTRPs), belonging to the CTRP superfamily, are extensively involved in regulating metabolism and the immune-inflammatory response. The inflammatory process is linked to the pathogenesis of coronary artery disease (CAD). Here, we investigated the association of serum levels of CTRP1 with CAD. Methods Study participants were divided into two groups according to the results of coronary angiography: a control group (n = 63) and a CAD group (n = 76). The concentrations of serum CTRP1 and inflammatory cytokines were determined by enzyme-linked immunosorbent assay. Further analysis of CTRP1 levels in individuals with different severities of CAD was conducted. The CAD severity was assessed by Gensini score. Results Serum levels of CTRP1 were significantly higher in CAD patients than in controls (17.24 ± 1.07 versus 9.31 ± 0.56 ng/mL), and CTRP1 levels increased with increasing severity of CAD. CTRP1 levels were positively correlated with concentrations of tumor necrosis factor-α and interleukin-6. Multiple logistic regression analysis showed that CTRP1 was significantly associated with CAD. Conclusions Our data showed close associations of serum CTRP1 levels with the prevalence and severity of CAD, indicating that CTRP1 can be regarded as a novel and valuable biomarker for CAD.

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.
