Does low-density lipoprotein cholesterol determine oxidative stress and endothelial dysfunction in saphenous veins from patients with coronary artery disease?
Endothelial dysfunction is associated with raised levels of superoxide and biomarkers of oxidative stress in saphenous veins from CAD patients. LDL cholesterol is a major determinant of endothelial dysfunction and oxidative stress in these patients. These results support intensive LDL cholesterol-lowering therapy as suggested by recent clinical trials.
The double poling ergometer is similar to a field test for evaluating peak VO(2) in elite cross country sit skiers; however, the ergometer test elicits a higher heart rate and anaerobic response.
