  2. Oxygen = Minimizes ischemia
  3. Beta Blockers = DEC HR –> DEC Arrhythmia risk and DEC O2 demand
  4. [ASA and Heparin] = limits thrombosis
  5. Morphine = Pain
  6. ACEk2 inhibitors within 24 hrs= DEC [L Ventricle Dilation/Remodeling]

Q

Which HTN med causes isolated peripheral edema and why? How do you correct for this and why does it work?

A

[ACEk2 inhibitors preferentially dilate Veins].

So [DHP CCB] + [ACEk2 inhibitors] concurrent = ⬇︎peripheral edema
