    • Although long-term use of cyclooxygenase (COX)-2 inhibitors may be associated with increased cardiovascular risk, their effects on vascular reactivity in atherosclerosis has remained largely unexplored. The aim of the present study was to evaluate the role of COX-2 induced by an atherosclerotic process, in the local control of vascular tone. New Zealand White rabbits were fed 0.3% cholesterol and subjected to balloon injury of the abdominal aorta. After 2 wk, the aorta was removed and used for organ bath experiments and immunohistochemistry, and the prostaglandins released were measured using enzyme immunoassays. Hypercholesterolemia and vascular injury significantly increased the thickness of the intimal layer, which was associated with an induction of COX-2 immunoreactivity throughout the aortic wall. In these preparations, a significant decrease of the maximal contractions induced by norepinephrine was observed. The norepinephrine-induced contractions of atherosclerotic preparations were restored by the COX inhibitors DuP-697 (0.5 μmol/l) and indomethacin (1.7 μmol/l), to similar contractions as was observed in aortic preparations derived from healthy rabbits. Norepinephrine stimulation of the abdominal aorta was accompanied by increased levels of prostaglandin I2 but not of prostaglandin E2, prostaglandin D2, or thromboxane A2 in atherosclerotic compared with normal aorta. Selective COX-2 inhibition significantly decreased the prostaglandin I2 release from atherosclerotic aorta but had no effect on the prostaglandin release from aortic preparations derived from normal rabbits. These observations suggest that the local induction of COX-2 during atherosclerosis decreased the sensitivity to norepinephrine and that COX-2 inhibitors may increase vascular reactivity at sites of atherosclerotic lesions.
