Background This study aimed to explore predictive biomarkers of coronary collateralization in patients with chronic total occlusion. Methods and Results By using a microarray expression profiling program downloaded from the Gene Expression Omnibus database, weighted gene coexpression network analysis was constructed to analyze the relationship between potential modules and coronary collateralization and screen out the hub genes. Then, the hub gene was identified and validated in an independent cohort of patients (including 299 patients with good arteriogenic responders and 223 patients with poor arteriogenic responders).

Article Synopsis
  • Higher levels of N-epsilon-carboxymethyllysine (CML), a type of advanced glycation end-product, are linked to reduced collateral vessel formation in patients with type 2 diabetes and chronic total occlusion of coronary arteries.
  • The study analyzed 242 patients, categorizing them into groups based on their collateral vessel development, revealing significantly higher CML levels in those with poor collateralization.
  • The results highlight that CML levels serve as independent indicators of poor coronary collateral vessel formation, suggesting potential implications for cardiovascular risk management in diabetes.

Background: Our previous study suggested that heart-type fatty acid-binding protein (HFABP) levels were greatly elevated in the conditioned medium of explant culture of in-stent restenosis (ISR) tissue from diabetic minipigs compared with those of non-ISR tissue. We here verified this result in animal tissues and investigated the impact of HFABP overexpression in human aortic smooth muscle cells (hASMCs).

Methods And Results: In Western blot and real-time RT-PCR, HFABP protein and mRNA levels were significantly higher in ISR than in non-ISR tissues from minipigs, and higher in the ISR tissue from diabetic minipigs than that from nondiabetic minipigs.

Background And Aims: Macrophage is a major contributor to the development of atherosclerosis by taking up deposited lipoprotein and eliciting local inflammation. Previously, we and others have shown C1q/TNF-related proteins (CTRPs) play diverse roles in vascular functions. In this study, we sought to investigate the changes in CTRP expression levels during vital biological processes in macrophages and their relation to inflammatory responses.

Aims: We investigated the association of the adipokine C1q/TNF-related protein (CTRP) 1 with coronary artery disease (CAD), and the biological vascular effects of CTRP1.

Methods And Results: We analysed CTRP1 levels in sera of CAD patients (n = 451) and non-CAD controls (n = 686), and in coronary endarterectomy specimens (n = 32), non-atherosclerotic internal mammary arteries (n = 26), aortic atherosclerotic plaques (n = 15), and non-atherosclerotic aortic samples (n = 10). C1q/TNF-related protein-levels were higher in sera, endarterectomy specimens, aortic atherosclerotic plaques, and peripheral blood mononuclear cells (PBMCs) from CAD patients compared with controls, and were related to CAD severity.

Background And Aim: Glycated albumin (GA) and the endogenous secretory receptor for advanced glycation endproducts (esRAGE) may modulate risk related to atherosclerosis. We tested the hypothesis that elevated GA and reduced esRAGE in serum are associated with adverse clinical outcomes in patients with type 2 diabetes and stable coronary artery disease (CAD).

Methods: We determined GA and esRAGE serum levels in 576 consecutive patients with type 2 diabetes and stable CAD undergoing sirolimus-eluting stent (SES)-PCI.

Objective: To investigate whether apolipoprotein A (apoA)-I glycation and paraoxonase (PON) activities are associated with the severity of coronary artery disease (CAD) in patients with type 2 diabetes mellitus (T2DM).

Methods: Relative intensity of apoA-I glycation and activities of high-density lipoprotein (HDL)-associated PON1 and PON3 were determined in 205 consecutive T2DM patients with stable angina with (n = 144) or without (n = 61) significant CAD (luminal diameter stenosis ≥ 70 %). The severity of CAD was expressed by number of diseased coronary arteries, extent index, and cumulative coronary stenosis score (CCSS).

Aims: We here investigated the endothelial effects of the chromogranin A-derived peptide vasostatin-2 and its relation to coronary artery disease (CAD).

Methods And Results: We assessed the impact of recombinant vasostatin-1 and vasostatin-2 on tumour necrosis factor-alpha (TNFα)-, angiotensin II-, and oxidized low-density lipoprotein (oxLDL)-induced expression of adhesion molecules in human arterial endothelial cells. Vasostatin-1 and vasostatin-2 levels were examined in coronary endarterectomy specimens (n= 23), atherosclerotic aortas (n= 16), non-significant-atherosclerotic internal mammary arteries (n= 30), and non-atherosclerotic aortas (n= 10), as well as in peripheral blood mononuclear cells (PBMCs) from severe CAD patients (n= 50) and healthy volunteers (n= 21).

Background: Glycated albumin (GA) has been shown to be a better indicator than glycosylated hemoglobin A1c (HbA1c) in terms of severity of renal impairment in patients with type 2 diabetes mellitus (T2DM). This study aimed to determine whether elevated serum GA levels are associated with an increased risk for contrast-induced acute kidney injury (CI-AKI) and worse clinical outcome in patients with T2DM and at least moderate renal insufficiency (RI) undergoing coronary angiography.

Methods: Serum levels of fasting blood glucose (FBG), HbA1c and GA were measured in 1030 patients with T2DM and moderate to severe RI (eGFR 15-59 mL/min/1.
