BACKGROUND Oxidative stress in the vasculature has been implicated in the pathogenesis of coronary artery disease (CAD). NADH/NADPH oxidase is a key enzyme of superoxide production in the vasculature. p22 phox, an essential component of NADH/NADPH oxidase, has four types of polymorphism. The C242T polymorphism changes histidine-72 to tyrosine, located in the potential heme-binding sites, wherea...

BACKGROUND Loss of endothelium-derived nitric oxide (EDNO) contributes to the clinical expression of coronary artery disease (CAD). Increased oxidative stress has been linked to impaired endothelial vasomotor function in atherosclerosis, and recent studies demonstrated that short-term ascorbic acid treatment improves endothelial function. METHODS AND RESULTS In a randomized, double-blind, pla...

BACKGROUND Metabolic syndrome (MetS) is a leading risk factor for coronary artery disease (CAD) in women. Reduced paraoxonase 1 (PON1) activity may play a role in the pathogenesis of atherosclerosis through increased susceptibility to lipid peroxidation in patients with MetS. AIM To examine whether there is a relationship between serum PON1 activity and MetS in women. METHOD The study group...

Coronary artery disease (CAD) is responsible for more than 7 million deaths worldwide. In the early stages of the development of atherosclerotic plaques, cardiovascular risk factors stimulate vascular endothelial cells, initiating an inflammatory process, fundamental in the pathogenesis of CAD. The inclusion of potentially cardioprotective foods, such as olive oil, to the diet, may aid in the c...

OBJECTIVE It has been reported that epicardial adipose tissue could locally modulate the coronary artery functions through secretion of proinflammatory and anti-inflammatory cytokines. Epicardial fat tissue is further implicated in the pathogenesis of coronary artery disease (CAD) because of its proximity to the adventitia of the major epicardial coronary arteries. We investigated the relations...

BACKGROUND AND PURPOSE C-reactive protein (CRP) is associated with atherogenesis and stroke in mostly elderly subjects. We tested whether elevated CRP may also be linked to spontaneous cervical artery dissection (CAD) and cryptogenic stroke. METHODS We investigated high-sensitivity CRP levels in 62 patients <60 years of age experiencing cerebral ischemia resulting from large artery atheroscle...

OBJECTIVE Traditional risk factors for coronary artery disease (CAD) fail to adequately distinguish patients who have atherosclerotic plaques susceptible to instability from those who have more benign forms. Using plasma lipid profiling, this study aimed to provide insight into disease pathogenesis and evaluate the potential of lipid profiles to assess risk of future plaque instability. METHO...

Coronary artery disease (CAD) is the most common type of cardiovascular disease and leading cause of mortality worldwide. Microarray technology for gene expression analysis has facilitated the identification of the molecular mechanism that underlies the pathogenesis of CAD. Previous studies have primarily used variance or regression analysis, without considering array specific factors. Thus, th...

fibrosis is the pathological condition resulting in the growth of excess fibrous connective tissue in an organ or body system as a reparative or reactive process. in the field of clinical pathology, clinicians and medical scientists are endeavoring to translate experimental knowledge into effective, innovative treatments for a range of fibrotic conditions. the amelioration of whole organ functi...
