All of the following are the actions of β–blockers in CHF except:: (A) Decrease in mortality associated with CHF, (B) Antagonism of vasoconstriction due to sympathetic overactivity, (C) Prevention of pathological remodelling of ventricular myocardium, (D) Prevention of dangerous cardiac arrhythmias
Answer is B. Beta blockers may actually increase vasoconstriction by antagonizing the vasodilator action of β2 receptors.
