One such tool is maximal cardiopulmonary exercise testing (CPET). This is the gold standard for measuring exercise capacity. However, maximal CPET is expensive, has extensive set-up and space requirements, needs direct medical supervision, and involves interpretive complexity; these factors have limited the widespread use of maximal ...

Endothelial dysfunction, or abnormal functioning of the lining of blood vessels, appears to be a key process in the development of cardiovascular disease. Endothelial dysfunction appears to be caused by both sleep disordered breathing and obesity. As endothelial dysfunction is among the first clinical marker that predicts future cardiovascular events, understanding molecular mechanisms leading to impairment of endothelial function is very important. Endothelial function requires the proper functioning of endothelial nitric oxide synthase (eNOS). eNOS activity is tightly regulated by caveolin-1, a protein important in the formation of cellular structures called caveolae. Low levels of caveolin-1 facilitate optimal nitric oxide ...
