Consult Cardiology or Cardiothoracic Surgery
Supportive measures until definitive surgery
Appropriate treatment if myocardial infarction must include catheterization or thrombolysis
Pulmonary edema
Oxygen
Nitrates and diuresis may improve filling pressures and treat edema
Early intubation for impending respiratory failure
Decrease afterload
Nitroprusside can be considered in normotensive patients to increase cardiac output and decrease<unk> 
Intra aortic balloon pump may decrease afterload, increase forward cardiac output and reduce<unk> 
Inotropes
Dobutamine pressor of choice as α agonism and increased afterload minimal compared to beta agonism
Avoid beta-blockers as mild to moderate tachycardia allows less time for LV to backfill
