    Beta blockers if non-selective ...meaning blocking b1 ( decreasing HR) and blocking B2 ( VD and decrease TPR) ...but if you think about all other antihypertensive meds can do the same ...then the question is why B blockers then Aortic Dissection ?
    the answer is ..it is the only antihypertensive that has to do with decrease the shearing force of the blood in thoracic aorta or downstream in the abdominal aorta

    they asked something like this in my exam

    good luck guys if you have a qs regards CVS let me ...i love this....
