Suitable bone markers assessing bone status in patients with both coronary artery disease and diabetes.

ABSTRACT: We aimed to investigate the bone turnover markers in coronary artery disease (CAD) patients with and without type 2 diabetes (T2DM) in comparison with control subjects without CAD and T2DM.This cross-sectional study was performed on 45 subjects undergoing elective heart surgery; either for coronary artery bypass grafting or for valve surgery. According to angiographic results, participants were grouped in two groups with CAD (n = 33) and without CAD (n = 12). The serum levels of osteocalcin (OC), procollagen I aminoterminal propeptide (P1NP) and carboxy-terminal collagen crosslinks (CTX), as bone turnover markers, as well as serum levels of 25 (OH) vitamin D3, PTH, and common metabolic factors were analyzed in all participants.Serum levels of bone markers did not differ in patients with CAD compared to non-CAD subjects. Regarding metabolic factors, serum levels of FBG had invert correlation with OC in CAD patients (p = 0.004). The data of subgroup analysis showed serum levels of OC and CTX were statistically significant lower in CAD-DM than CAD-non DM (p < 0.05). There were not any significant differences in the P1NP levels between groups.Our data suggest that CTX and OC would be used as suitable bone markers in CAD patients with T2DM. However, further clinical studies need to establish the role of these markers in CAD patients with diabetes.

Genetic Markers for Coronary Artery Disease.

Project description:Coronary artery disease (CAD) and myocardial infarction (MI) are recognized as leading causes of mortality in developed countries. Although typically associated with behavioral risk factors, such as smoking, sedentary lifestyle, and poor dietary habits, such vascular phenotypes have also long been recognized as being related to genetic background. We review the currently available data concerning genetic markers for CAD in English and non-English articles with English abstracts published between 2003 and 2018. As genetic testing is increasingly available, it may be possible to identify adequate genetic markers representing the risk profile and to use them in a clinical setting.

Beyond Coronary Artery Disease: Assessing the Microcirculation.

Project description:Ischemic heart disease (IHD) affects more than 20 million adults in the United States. Although classically attributed to atherosclerosis of the epicardial coronary arteries, nearly half of patients with stable angina and IHD who undergo invasive coronary angiography do not have obstructive epicardial coronary artery disease. Ischemia with nonobstructive coronary arteries is frequently caused by microvascular angina with underlying coronary microvascular dysfunction (CMD). Greater understanding the pathophysiology, diagnosis, and treatment of CMD holds promise to improve clinical outcomes of patients with ischemic heart disease.

Expression profiling in exosomal miRNAs of diabetes, diabetes with coronary microcirculation disorder, and diabetes with coronary artery disease

Project description:Due to the insidious onset and the difficulty to diagnose and intervene, it is particularly important to find the diagnostic markers of diabetic coronary microcirculation disorder (CMD) and therapeutic targets. Circulating exosomes, as endogenous exosomes derived from multiple tissue cells, mediate communication between cells and tissues, may serve as a key point for future diagnosis, prognosis and personalized treatment of CMD in diabetes. Therefore, we isolated serum exosomes from patients with diabetes, as well as patients with CMD or coronary artery disease (CAD) respectively. We explored the differences in characteristics between three circulating exosomes.

Transcriptional profiles associated with coronary artery disease in Type 2 diabetes mellitus

Project description:Coronary artery disease (CAD) is a common complication of Type 2 diabetes mellitus (T2DM). Understanding the pathogenesis of this complication is essential in both diagnosis and management. Thus, this study aimed to characterize the presence of CAD in T2DM using molecular markers and pathway analyses. Total RNA from peripheral blood mononuclear cells (PBMCs) underwent whole transcriptomic profiling using the Illumina HumanHT-12 v4.0 expression beadchip. Differential gene expression with gene ontogeny analyses was performed, with supporting correlational analyses using weighted correlation network analysis (WGCNA)

Genetic Markers of Insulin Resistance and Atherosclerosis in Type 2 Diabetes Mellitus Patients with Coronary Artery Disease.

Project description:Type 2 diabetes mellitus (T2DM) is characterized by impaired insulin secretion on a background of insulin resistance (IR). IR and T2DM are associated with atherosclerotic coronary artery disease (CAD). The mechanisms of IR and atherosclerosis are known to share similar genetic and environmental roots. Endothelial dysfunction (ED) detected at the earliest stages of IR might be the origin of atherosclerosis progression. ED influences the secretion of pro-inflammatory cytokines and their encoding genes. The genes and their single nucleotide polymorphisms (SNPs) act as potential genetic markers of IR and atherosclerosis. This review focuses on the link between IR, T2DM, atherosclerosis, CAD, and the potential genetic markers CHI3L1, CD36, LEPR, RETN, IL-18, RBP-4, and RARRES2 genes.

"Desert" gene (Chr9p21) variants as novel markers for coronary artery disease.

Project description:OBJECTIVE:Previous reports have denoted to the possible link of Chr9p21 locus to the incidence of coronary artery disease (CAD). The entire core of chr9p21 is covered by "ANRIL" (Antisense noncoding RNA in INK4 Locus) and lies in a region that is free from any coding proteins; therefore, it is called the desert gene. The major objectives of this study were to examine the association of rs10757278 and rs2383206 SNPs on Chr9p21 with the incidence of CAD in the presence and absence of type 2 diabetes (T2D) in Egyptians and to correlate these genetic variants with several disease biomarkers (TC, CRP, and HbA1c). METHODS:The study subjects consisted of 150 subjects; 50 healthy controls and 100 patients that were divided into two groups; CAD patients and CAD T2D patients. The genotyping of SNPs was performed using qPCR. RESULTS:Genotype distribution for both SNPs were found to be significantly different (p=0.0009 for rs10757278 and p=0.001 for rs2383206) between patients and controls. The allele frequency was also different for rs10757278. CONCLUSION:The current study showed that rs10757278/rs2383206-G allele increases the risk for CAD in Egyptians. Moreover, AA variant appeared as a protective genotype. However, SNPs did not noticeably contribute in the elevation of TC, hs-CRP, and HbA1c in non-diabetic and diabetic CAD patients.

Screening for Coronary Artery Disease in Patients with Diabetes.

Project description:Purpose of reviewThe study aims to describe methods for detecting subclinical coronary artery disease (CAD) and their potential implications in asymptomatic patients with diabetes.Recent findingsImaging tools can assess non-invasively the presence and severity of CAD, based on myocardial ischemia, coronary artery calcium score, and coronary computed tomography coronary angiography. Subclinical CAD is common in the general population ageing 50 to 64 years with any coronary atherosclerosis present in 42.1% and obstructive CAD in 5.2%. In patients with diabetes, an even higher prevalence has been noted. The presence of myocardial ischemia, obstructive CAD, and the extent of coronary atherosclerosis provide powerful risk stratification regarding the risk of cardiovascular events. However, randomized trials evaluating systematic screening in the general population or patients with diabetes have demonstrated only moderate impact on management and no significant impact on patient outcomes. Despite providing improved risk stratification, systematic screening of CAD is not recommended in patients with diabetes.

Percutaneous Coronary Intervention for Left Main Coronary Artery Disease: Present Status and Future Perspectives.

Project description:For several decades, coronary artery bypass grafting has been regarded as the standard choice of revascularization for significant left main coronary artery (LMCA) disease. However, in conjunction with remarkable advancement of device technology and adjunctive pharmacology, percutaneous coronary intervention (PCI) offers a more expeditious approach with rapid recovery and is a safe and effective alternative in appropriately selected patients with LMCA disease. Several landmark randomized clinical trials showed that PCI with drug-eluting stents for LMCA disease is a safe option with similar long-term survival rates to coronary artery bypass grafting surgery, especially in those with low and intermediate anatomic risk. Although it is expected that the updated evidence from recent randomized clinical trials will determine the next guidelines for the foreseeable future, there are still unresolved and unmet issues of LMCA revascularization and PCI strategy. This paper provides a comprehensive review on the evolution and an update on the management of LMCA disease.
