Condition

Intervention
Patients will be randomly assigned to either the experimental intervention of oral metoprolol or the control intervention, a placebo. Patients will receive their first dose of metoprolol CR or placebo two to four hours pre-operatively at a strength of 100 mg (1/2 of a 200 mg tablet). Patients will then receive their second dose of their assigned intervention during the first 6 hours or at 6 hours post surgery. Twelve hours after the second post-op dose, patients will start taking a daily dose of 200 mg of either metoprolol CR or placebo for a duration of 30 days post surgery.

Participant exclusion criteria
1. Contradiction to metoprolol including any of the following: significant bradycardia (heart rate less than 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
