How do BBs work?
decrease HR, contractility and BP
they prevent and decrease angina by decreasing myocardial oxygen demand

Non-DHPs:
-act more centrally and behave similar to BBs (decrease oxygen demand by decreasing HR, contractility and BP)
How do DHP CCBs work?
primarily cause arterial dilation
