Relationship Between Red Cell Distribution Width and Oxidative Stress Indexes in Patients with Coronary Artery Disease.

Background: Red blood cell distribution (RDW), an index of the size variability of erythrocytes, is significantly associated with coronary stenosis and can strongly predict the mortality risk in coronary artery disease (CAD). The biological mechanisms involved are not fully understood but may include oxidative stress. We sought to investigate the relationship between RDW and markers of oxidative stress in patients with CAD.

Association of the serum apelin, but not ghrelin, with the presence and severity of coronary artery disease.

Increasing evidence suggests that apelin and ghrelin may participate in atherogenesis. We sought to investigate whether the serum levels of apelin and ghrelin are significantly different in patients with coronary artery disease (CAD) compared to patients with nonsignificant coronary stenosis and determine the correlation between these adipokines and the severity of coronary stenosis. The study population included 31 stable CAD patients, 38 unstable CAD patients, and 39 non-CAD subjects.

Decreased Na+/K+-ATPase Activity and Altered Susceptibility to Peroxidation and Lipid Composition in the Erythrocytes of Metabolic Syndrome Patients with Coronary Artery Disease.

Background: The increased generation of reactive oxygen species that occurs in the case of a metabolic syndrome (MetS) may be responsible for the increased oxidative injury to erythrocyte membranes in coronary artery disease (CAD). Therefore, we studied the effects of MetS on both indexes of oxidative damage and biochemical properties of erythrocyte membranes in CAD patients.

Methods: We analyzed the markers of oxidative stress, Na+/K+-ATPase activity, total cholesterol content of erythrocyte membranes (CEM), and fatty acid compositions of the erythrocyte membrane in 82 patients with stable CAD and 39 non-CAD subjects.

Investigation of membrane fatty acid profiles in erythrocytes of patients with stable coronary artery disease.

Background: The association between the erythrocyte membrane fatty acids and the severity of coronary stenosis has not been studied in patients with stable coronary artery disease (CAD).

Objective: We sought to investigate whether the fatty acid profile of erythrocyte membranes is significantly different in patients with stable CAD compared with patients with nonsignificant coronary stenosis and evaluate a possible relationship between fatty acid profile and the severity of coronary stenosis.

Methods: The population included 144 patients, undergoing clinically indicated coronary angiography.

Association of the total cholesterol content of erythrocyte membranes with the severity of disease in stable coronary artery disease.

Increasing evidence suggests that erythrocytes may participate in atherogenesis. We sought to investigate whether the total cholesterol content of erythrocyte membranes (CEM) is significantly different in patients with stable coronary artery disease (CAD) compared to patients with nonsignificant coronary stenosis and determine the correlation between CEM and the severity of coronary stenosis.
