increase O2 deliver and decrease O2 consumption

Nitrates (vasodialtion)
Beta blockers (heart depressant)
Calcium blocker
Calcium blocker
decrease O2 demand,afterload,contractility& HR
Beta blockers (heart depressant)
decrease H.R., contractility, BP, and afterload so reduce myocardial O2 consumption.

precatutions: bradycardia, and patients with asthma.
Nitrates (Nitroglycerin)
Venous dilation predominates with nitroglycerin which decreases cardiac preload and O2 consumption.
shock treatment MOA
inotropic and vasopresser
causes of shock 6
blood flow
Dopamine for shock

lrg amt increase CO and peripheral vasoconstriction
