Pages: 168 - 169
Background. Organic nitrates (e.g. nitroglycerin) are highly selective dilators of muscular conduit arteries. By contrast, the endogenous inorganic nitrite anion (NO2−) is thought to be a hypoxia-dependent dilator of small resistance arterioles, via its reduction to vasodilating nitric oxide (NO) by...

Background. The anticontractile effect of perivascular adipose tissue(PVAT) is lost in obese patients due to adipocyte hypertrophy, leading to hypoxia, inflammation, and oxidative stress(Circulation 2009; 119(12):1661–1670).We recently demonstrated that the property of PVAT, partially maintained in an...
