The vascular endothelium is a monolayer of cells between the vessel lumen and the vascular smooth muscle cells. Nitric oxide (NO) is a soluble gas continuously synthesized from the amino acid L-arginine in endothelial cells by the constitutive calcium-calmodulin-dependent enzyme nitric oxide synthase (NOS). This substance has a wide range of biological(More)
Insulin resistance and the vascular complications of diabetes include activation of the inflammation cascade, endothelial dysfunction, and oxidative stress. The comorbidities of diabetes, namely obesity, insulin resistance, hyperglycemia, hypertension and dyslipidemia collectively aggravate these processes while antihyperglycemic interventions tend to(More)
Patients with diabetes mellitus (DM) have a high prevalence of coronary artery disease (CAD), as diabetes is implicated in the formation of atherosclerotic plaque. Endothelial dysfunction is one of the precursor key steps in the development of atherosclerosis in diabetic subjects. Decreased nitric oxide (NO) production, increased oxidative stress and(More)
Patients with diabetes mellitus (DM) type 2 have a high prevalence of coronary artery disease (CAD), as diabetes is implicated in the formation of atherosclerotic plaque. Hyperglycemia, elevated free fatty acid, increased amount of circulating end-glucosylated serum products and insulin resistance are the main mechanisms involved in the accelerated(More)
Atherosclerosis is a disease of arteries and is characterized by endothelial dysfunction, vascular inflammation, and the build-up of lipids, cholesterol, calcium, and cellular debris within the intima of the vessel wall. A number of factors commonly characterized as "risk factors" for atherosclerosis have been identified to facilitate the development of(More)
Atherosclerosis is a very complex procedure responsible for the development of coronary artery disease which is the leading cause of death in the civilized world. The obvious pandemic character of atherosclerosis augments the need to discover an ideal biomarker, which will be able to facilitate the clinical diagnosis of the atherosclerosis from the(More)
Experimental studies suggest that bone marrow-derived endothelial progenitor cells (EPCs) play an important role in the maintenance of endothelial integrity and hemostasis. The number of circulating EPC has been shown to be inversely correlated with cardiovascular risk factors and vascular function and to predict cardiovascular events independent of both(More)
Heart failure (HF) represents a complex multifactorial syndrome, characterized by crucial structural and functional abnormalities of the myocardium. Matrix metalloproteinases are associated with left ventricular dysfunction, adverse left ventricular remodelling and prognosis after acute myocardial infarction. There is a strong association between oxidative(More)
C-reactive protein (CRP) is an acute phase protein and a biochemical marker with important prognostic value for cardiovascular events. Interleukins IL-1 and IL-6 are implicated in the pathogenesis of atherosclerosis and are associated with CRP. Apolipoproteins ApoA-I and ApoB are the main lipid metabolic markers implicated in the development and progression(More)
Endothelial dysfunction reflected by reduced nitric oxide availability is nowadays considered as a causative factor of atherosclerosis. A variety of biomarkers has been used as indicators of endothelial dysfunction in cardiovascular disease. Discovered just over a decade ago, microRNAs have evoked a great deal of interest, due to their importance for many(More)
