Title: Perioperative Ischemic Evaluation Study (POISE) Trial
Brief Summary: This trial will evaluate the ability of metoprolol (a beta-blocker drug) to prevent heart attacks and deaths around the time of surgery.


Options:
A: Inclusion Criteria:

* Patients with STEMI after primary PCI
* Patients with left ventricular ejection fraction more than or equal to 40%

Exclusion Criteria:

* Patients with left ventricular ejection fraction less than 40%
* Patients with contraindication for beta-blocker
* Patients with implantable cardioverter defibrillators
* Patients with end-stage malignancy
B: Inclusion Criteria:

* Left ventricular ejection fraction \> 40%
* Myocardial infarction (MI) within previous two weeks

The diagnosis of acute MI must meet the Universal European Society of Cardiology (ESC) definition of MI

Exclusion Criteria:

* Clinical evidence of heart failure at the time of discharge
* Pregnancy or of child bearing age not using safe anticonception throughout the study period
* Lack of signed informed consent and expected cooperation during follow-up
* Any medical condition where beta blocker treatment is indicated according to the treating physician
C: Inclusion Criteria:

* Patients undergoing noncardiac surgery
* ≥ 45 years of age; either sex.
* Have an expected length of stay ≥ 24 hours
* Fulfill any one of the following 6 criteria:

  * coronary artery disease;
  * peripheral vascular disease;
  * history of stroke due to atherothrombotic disease;
  * hospitalization for congestive heart failure within 3 years of randomization;
  * undergoing major vascular surgery; OR
  * any 3 of the following 7 criteria: scheduled for high risk surgery (i.e. intraperitoneal or intrathoracic); emergency/urgent surgery; any history of congestive heart failure; history of a transient ischemic attack (TIA); diabetes and currently on an oral hypoglycemic agent or insulin therapy; preoperative serum creatinine \> 175 µmol/L (\> 2.0 mg/dl); or age \> 70 years.

Exclusion Criteria:

* Contraindication to metoprolol including any of the following: significant bradycardia (heart rate \< 50 beats per minute); second or third degree heart block without a pacemaker; asthma that has been active within the last decade; and history of chronic obstructive pulmonary disease (COPD) with bronchospasm on pulmonary function tests.
* Clinical plan to use a beta-blocker preoperatively or during the first 30 postoperative days
* Prior adverse reaction to a beta-blocker
* Coronary artery bypass graft (CABG) surgery with complete revascularization in the preceding 5 years and no evidence of cardiac ischemia since the CABG surgery
* Patients undergoing low risk surgical procedures (potential examples include transurethral procedures \[transurethral prostatectomies (TURPs), stone baskets, etc.\], ophthalmologic procedures under topical or regional anesthesia \[cornea transplants, cataract surgery, etc.\], and surgeries with limited physiological stresses \[digital re-implantation, nerve repairs, etc.\] )
* Concurrent use of verapamil
* Prior enrollment in this trial
D: Inclusion Criteria:

* Patients presenting with ST elevation, left bundle branch block or ST depression within 24 hours of the onset of the symptoms of suspected acute MI

Exclusion Criteria:

* clear indications for, or contraindications to, any of the study treatments
