Abstract
BACKGROUND Coronary artery disease (CAD) is a complex disease that is influenced by environmental and genetic factors. In this study, we aimed to investigate the relationship between coding variants in lipid metabolism-related genes and CAD in a Chinese Han population. METHODS A total of 252 individuals were recruited for this study, including 120 CAD patients and 132 healthy control individuals. Rare and common coding variants in 12 lipid metabolism-related genes (ANGPTL3, ANGPTL4, APOA1, APOA5, APOC1, APOC3, CETP, LDLR, LIPC, LPL, PCSK9 and SCARB1) were detected via next-generation sequencing (NGS)-based targeted sequencing. Associations between common variants and CAD were evaluated by Fisher's exact test. A gene-based association test of rare variants was performed by the sequence kernel association test-optimal (SKAT-O test). RESULTS We found 51 rare variants and 17 common variants in this study. One common missense variant, LIPC rs6083, was significantly associated with CAD after Bonferroni correction (OR = 0.47, 95% CI = 0.29-0.76, p = 1.9 × 10- 3). Thirty-three nonsynonymous rare variants were identified, including two novel variants located in the ANGPTL4 (p.Gly47Glu) and SCARB1 (p.Leu233Phe) genes. We did not find a significant association between rare variants and CAD via gene-based analysis via the SKAT-O test. CONCLUSIONS Targeted sequencing is a powerful tool for identifying rare and common variants in CAD. The common missense variant LIPC rs6083 confers protection against CAD. The clinical relevance of rare variants in CAD aetiology needs to be investigated in larger sample sizes in the future.

Abstract
OBJECTIVE Coronary artery disease (CAD) is a complex disorder influenced by genetic and environmental factors. This case-control study investigated the association between Sirtuin SIRT3 gene polymorphisms, serum malondialdehyde (MDA) levels, and CAD susceptibility. METHODS Blood samples were collected from 70 CAD cases and 30 controls at the Cardiac Center, Azadi Teaching Hospital, Duhok, Iraq. Genomic DNA was extracted, and PCR-based allele genotyping determined SIRT3 rs11246029 T/C polymorphisms. Serum MDA levels were measured using ELISA. Statistical analysis included t-tests, Mann-Whitney tests, and Spearman correlations. Odds ratios (OR) with 95% confidence intervals (CI) assessed genotypes/alleles and CAD associations. The accuracy of serum MDA in predicting the severity of CAD was evaluated using receiver operating characteristic (ROC) curve analysis. RESULTS There were no significant variations in serum MDA levels between controls and CAD patients in the study. The diagnostic accuracy of serum MDA for CAD severity prediction was modest (Area Under Curve (AUC) = 0.56). Correlations revealed associations between MDA and total bilirubin (negative) and Troponin (positive). CRP correlated positively with LDH, glucose, cholesterol, LDL, CKmB, and Troponin. CKmB and Troponin are positively associated with clinical characteristics. Genotype analysis identified a significantly higher CAD risk with the CC genotype compared to controls. CONCLUSION These findings shed light on the potential role of SIRT3 gene polymorphisms and serum MDA levels in CAD susceptibility. Further research is needed to understand underlying mechanisms and therapeutic implications based on these markers. TRIAL REGISTRATION 15092021-9-12. Registered 15 September 2021.

Feedback regulation of coronary artery disease susceptibility gene ADTRP and LDL receptors LDLR/CD36/LOX-1 in endothelia cell functions involved in atherosclerosis.

Abstract
A high level of low-density lipoprotein cholesterol (LDL) is one of the most important risk factors for coronary artery disease (CAD), the leading cause of death worldwide. However, a low concentration of LDL may be protective. Genome-wide association studies revealed that variation in ADTRP gene increased the risk of CAD. In this study, we found that a low concentration of oxidized-LDL induced the expression of ADTRP. Further analyses showed that knockdown of the expression of LDL receptor genes LDLR, CD36, or LOX-1 significantly downregulated ADTRP expression, whereas overexpression of LDLR/CD36/LOX-1 markedly increased ADTRP expression through the NF-κB pathway. Like ADTRP, LDLR, CD36 and LOX-1 were all involved in endothelial cell (EC) functions relevant to the initiation of atherosclerosis. Downregulation of LDLR/CD36/LOX-1 promoted monocyte adhesion to ECs and transendothelial migration of monocytes by increasing expression of ICAM-1, VCAM-1, E-selectin and P-selectin, decreased EC proliferation and migration, and increased EC apoptosis, thereby promoting the initiation of atherosclerosis. Opposite effects were observed with the overexpression of ADTRP and LDLR/CD36/LOX-1 in ECs. Interestingly, through the NF-κB and AKT pathways, overexpression of ADTRP significantly upregulated the expression of LDLR, CD36, and LOX-1, and knockdown of ADTRP expression significantly downregulated the expression of LDLR, CD36, and LOX-1. These data suggest that ADTRP and LDL receptors LDLR/CD36/LOX-1 positively regulate each other, and form a positive regulatory loop that regulates endothelial cell functions, thereby providing a potential protective mechanism against atherosclerosis. Our findings provide a new molecular mechanism by which deregulation of ADTRP and LDLR/CD36/LOX-1 promote the development of atherosclerosis and CAD.

Abstract
Cardiac risk stratification before surgery informs consent, may advise optimization interventions, and guides intraoperative and postoperative management and monitoring. Published guidelines provide an outline for risk stratification but are only updated every 5 to 10 years; hence, cardiology expert opinion is often needed. Preoperative cardiovascular evaluation starts with an excellent history and physical examination. Accurate assessment of exercise tolerance is paramount in defining risk and determining the need for further testing. Risk/benefit ratio needs to be assessed and reviewed with all stakeholders, which pertains to deciding on cardiac intervention before surgery and bleeding versus thrombosis risk when managing medications.
