The inflammatory process in the atherosclerotic artery may lead to increased blood levels of inflammatory cytokines. The aim of this study is to understand the role of inflammatory markers in the development of coronary artery disease. Therefore, a case-control study was conducted amongst coronary artery disease patients who attended the Sudan Heart Institute and healthy controls. Questionnaires were designed to determine the lifestyle and environmental factors for 200 participants (100 cases, 100 controls). Blood samples were collected to measure lipids profiles using enzymatic colorimetric and DNA extraction using the G-spin Kits. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used for IL-6 and IL-16 genotyping. A total of 64% patients were males, 41% were at 51-61 years, and physical activity was common in 60% of the patients. The risk factors for coronary artery disease were hypertension 62%, angina 62%, cigarette smoking 38%, diabetes 33%, tobacco user 31%, drinking alcohol 24% and stroke 2%. Most patients had a family history of stroke 93%, hypertension 36%, diabetes 34%, angina 9%, and heart attack 4%. Total cholesterol and low-density lipoprotein were significantly different (P>0.05) between cases and controls, and they were significantly associated with IL-16 genotype. All risk factors for coronary artery diseases were strongly associated with IL-6 genotype (P-value < 0.05, OR >1). Whereas, IL-16 homozygous TT genotype was significantly associated with gender and physical activity. Lifestyle, family history, and IL-16 (TT) genotype are risk factors for coronary artery disease in Sudanese patients.

Background: Individuals with no history of coronary artery disease can develop acute coronary syndrome (ACS), often in the absence of major risk factors including low-density lipoprotein cholesterol (LDL-C). We identified risk factors and biomarkers that can help identify those at discordantly high risk of ACS who have normal LDL-C using a novel coronary artery disease predictive algorithm (CADPA) incorporating biomarkers of endothelial injury validated in the Multi-Ethnic Study of Atherosclerosis cohort. Methods: Five-year predicted ACS risk was calculated using the CADPA for 8589 patients. Common risk factors and serum levels of 9 biomarkers utilized by the CADPA were tracked. We identified a “discordant high ACS” risk group with serum LDL-C < 130 mg/dL but 5-year CADPA predicted risk ≥ 7.5% and a “discordant low ACS” risk group defined as LDL-C ≥ 130 mg/dL but 5-year CADPA risk of < 7.5%. Multiple logistic regression identified risk factors and biomarkers that predicted discordance in two separate models. Results: The average age and percent male of the high ACS discordant group was higher compared to non-discordant (68±10 vs 54±13 years and 61% vs 43%, respectively). Diabetes (OR 2.84 [2.21-3.66]), male sex (OR 2.83 [2.40-3.35]), family history (OR 2.23 [1.88-2.64]) and active smoking (OR 1.99 [1.50-2.62]) exhibited greatest odds of high ACS discordance compared to other risk factors (all p < 0.01). Increased serum soluble FAS (OR 2.12 [1.97-2.29]), Hemoglobin A1c (OR 1.60 [1.48-1.72]) and interleukin-16 (OR 1.40 [1.32-1.48]) were the biomarkers most associated with discordant risk, independent of global risk factors. Conclusion: Men with diabetes and family history of myocardial infarction who are actively smoking may be at highest risk of developing ACS despite controlled LDL-C. Future studies should examine whether using the CADPA can help identify such individuals that could benefit from earlier targeting of risk factor modification for prevention of ACS.

AbstractPCSK9 plays a crucial role in lipid metabolism. This case–control study explored the associations of novel single nucleotide polymorphisms (SNPs) of the PCSK9 gene with coronary artery disease (CAD) (≥ 1 coronary artery stenosis ≥ 50%) and its risk factors in the Han population in Xinjiang, China. Four tag SNPs (rs11583680, rs2483205, rs2495477 and rs562556) of the PCSK9 gene were genotyped in 950 CAD patients and 1082 healthy controls. The distributions of genotypes in rs2483205 and rs562556 were significantly different between the groups (all p < 0.05). The TT genotype of rs2483205, GG genotype of rs562556, and their H4 (T-G) haplotype were associated with CAD [odds ratio (OR) 0.65, confidence interval (CI) 0.45–0.95, p = 0.024; 0.63, 0.45–0.90, p = 0.011; 0.50, 0.35–0.70, p < 0.001, respectively]. Additionally, the model (TT + CT vs. CC) of rs2483205 was associated with increased risk of obesity, and the G allele of rs562556 was associated with lower low-density lipoprotein cholesterol (LDL-C), blood glucose, body mass index (BMI), and mean platelet volume (MPV) (all p < 0.05). rs2483205, rs562556, and their H4 haplotype of the PCSK9 gene were associated with CAD. Additionally, rs2483205 is associated with obesity, and rs562556 is associated with LDL-C, blood glucose, BMI, and MPV.

It has been suggested that antioxidized low-density lipoprotein (anti-oxLDL) antibodies play a role in the pathogenesis of atherosclerosis. The aim of this study was to measure serum ox-LDL IgG levels in 31 patients with angiographically defined coronary artery disease (CAD) (≥50% stenosis in at least one major coronary artery; CAD+group) and compare these levels with those of 32 subjects with <50% coronary stenosis (CAD−group) and 24 healthy age- and sex-matched controls using ELISA. We did not find any significant difference between CAD+, CAD−, and control groups in regard to oxLDL IgG levels (P=0.83). Serum oxLDL IgG levels did not differ between 1VD (one vessel disease), 2VD (2 vessels disease), and 3VD (3 vessels disease) subgroups of CAD+patients (P=0.20). Serum anti-oxLDL titers were only significantly correlated with LDL-C in the CAD+group (P<0.05) and waist and hip circumference (P<0.05andP<0.01, resp.) in the CAD−group. In stepwise regression analysis, none of the conventional cardiovascular risk factors was associated with serum ox-LDL IgG levels. The present results suggest that serum levels of ox-LDL IgG are neither associated with the presence and severity of CAD nor with the conventional cardiovascular risk factors.

Background and Objective: Coronary artery disease (CAD) and cancer are the leading causes of death worldwide and share some risk factors, such as aging and smoking. Concurrence of CAD and cancers makes diagnosis and treatment more clinical challenging. In patients who need stent implantation followed by dual antiplatelet therapy, fatal perioperative complications such as bleeding and stent thrombosis may occur. There is no data regarding the prevalence and risk factors of cancer in patients with CAD. This study investigated the cancer prevalence and risk factors in patients with newly diagnosed CAD. Methods and Results: Three thousand and one hundred and eighty six consecutive patients with newly angiographically documented CAD were prospectively enrolled between January 2009 and March 2015. Serum levels of tumor markers, including carcinoembryonic antigen, alpha fetoprotein, carbohydrate antigen125, carbohydrate antigen 153, carbohydrate antigen199, squamous cell cancer antigen, and prostate-specific antigen, were measured. Diagnosis of cancer was confirmed by pathology or imaging with ultrasound, computed tomography or magnetic resonance. The prevalence of cancer in CAD patients was 1.1% (35 out of 3186), involving the in gastroenterogical, respiratory, endocrine and exocrine, urinary and hematopoietic systems. Among these cancer patients, 17 patients had stent implantation, with 7 AMI patients undergoing emergency PCI. Multivariate analysis revealed that, in addition to male gender and advanced age, lower plasma low-density lipoprotein (LDL) cholesterol levels were independently associated with the occurrence of cancer in CAD patients (P<0.01). Conclusion: Cancers occur in 1.1% of patients with CAD. Low LDL levels may increase the risk for cancers in the CAD patients. Further large scale studies are needed to validate this association.
