AI Article Synopsis
- The study explores the link between specific genetic variations (NFKB1 and NFKBIA polymorphisms) and the risk of developing coronary artery disease (CAD) in a Chinese Uygur population.
- Researchers analyzed genetic data from nearly 1,000 CAD patients and over 1,000 controls, finding that one particular genetic variant (rs28362491) is significantly associated with an increased risk of CAD.
- Additionally, patients with stable angina pectoris showed higher levels of the inflammatory marker IL-6, suggesting that this genetic variant is linked to inflammation and CAD susceptibility.
Article Abstract
Objectives: Coronary artery disease (CAD) is the most common chronic inflammatory disease worldwide. NF-κB, a central regulator of inflammation, is involved in various inflammatory diseases. The aim of this study was to investigate the association between NFKB1 and NFKBIA polymorphisms and the susceptibility to CAD and their impact on plasma levels of IL-6 in a Chinese Uygur population.
Methods: We genotyped NFKB1-94ins/del ATTG (rs28362491) and NFKBIA3' UTR A/G (rs696) using TaqMan SNP genotyping assays in 960 Uygur CAD cases and Uygur 1060 CAD-negative controls. IL-6 plasma levels were measured in 360 stable angina pectoris (SAP) cases and 360 controls using ELISA method.
Results: There was no significant difference in the distribution of the genotypes and alleles of rs696 polymorphism in CAD cases and controls. Significant difference in the frequency of genotypes (P = 0.001) and alleles (P = 0.001) of rs28362491 polymorphism was observed in CAD cases compared to controls. In multivariate logistic regression analysis, SNP rs28362491 was consistently associated with CAD risk in a recessive model after adjustment for cardiovascular risk factors (OR = 1.581, 95% CI 1.222 to 2.046, P<0.001). SAP cases had significantly higher plasma levels of IL-6 compared to controls (P<0.001). General linear model analysis showed rs28362491 was independently associated with increased IL-6 levels by analyses of a recessive model (P<0.001) after adjustment for covariates.
Conclusions: Our study indicates that NFKB1-94 ins/del ATTG polymorphism may play a role in CAD susceptibility in Chinese Uygur population and is functionally associated with IL-6 expression, suggesting a mechanistic link between NFKB1-94 ins/del ATTG polymorphism and CAD susceptibility.

Background/aims: Alzheimer's Disease (AD) is a progressive neurodegenerative disorder that severely affects cognitive functions and memory. Early detection is crucial for timely intervention and improved patient outcomes. However, traditional diagnostic tools, such as MRI and PET scans, are costly and less accessible.

Background: Psychological disorders, such as anxiety and depression, are considered to be one of the causes of noncardiac chest pain (NCCP). And these patients can be challenging to differentiate from coronary artery disease (CAD), leading to a considerable number of patients still undergoing angiography. We aim to develop a practical prediction model and nomogram using cardiopulmonary exercise testing (CPET), to help identify these patients.

Background Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a key enzyme selectively expressed in unstable, rupture-prone atherosclerotic plaques. Previous research has established a strong link between the gene and the development of coronary artery disease (CAD). While traditional risk factors like cholesterol levels and blood pressure are valuable, there remains a need for more specific biomarkers to identify individuals at heightened risk of atherosclerosis before the onset of clinical symptoms.

Background: Coronary computed tomography angiography (CCTA) is a noninvasive cardiovascular imaging procedure that visualizes coronary artery calcifications (CAC), a marker of subclinical atherosclerosis. Due to different calcification patterns in patients with chronic kidney disease (CKD) compared to the general population, this study aims to present diagnostic cut-off values for CAC to detect early coronary artery disease (CAD) in CKD patients.
Methods: This cross-sectional study included 807 patients: 407 with CKD and 400 controls with normal kidney function who underwent CCTA during 2019-2021.
