Bronchial asthma: Increased sympathetic activity prevents bronchospasm in patients disposed to paroxysmal constriction of the bronchial tree (bronchial asthma, bronchitis in smokers). In this condition, ?2-receptor blockade will precipitate acute respiratory distress (B).
O2 demand falls because of the ensuing decrease in the two variables that determine systolic wall tension (afterload): ventricular filling volume and aortic blood pressure. Calcium antagonists (B) decrease O2 demand by lowering aortic pressure, one of the components contributing to afterload.
