Enhanced contribution of NO to exercise-induced coronary responses after α-adrenergic receptor blockade

We hypothesized that nitric oxide (NO), in addition to beta-adrenergic effects, may contribute to exercise-induced coronary responses after alpha-adrenergic receptor blockade. Data were analyzed as relationships between coronary sinus (CS) O2 saturation (CS O2sat) or coronary blood flow (CBF) and my...

Description
Summary:We hypothesized that nitric oxide (NO), in addition to beta-adrenergic effects, may contribute to exercise-induced coronary responses after alpha-adrenergic receptor blockade. Data were analyzed as relationships between coronary sinus (CS) O2 saturation (CS O2sat) or coronary blood flow (CBF) and myocardial O2 consumption (MVo2).
