Brief Summary
The Investigators will test the hypothesis that nonselective beta-blockers would have a more pronounced effect on platelet aggregation than selective beta-blockers in patients with acute coronary syndrome treated with dual anti platelet therapy.

Study Arms (2)
Carvedilol
ACTIVE COMPARATORPatients who have documented ACS, who are on dual antiplatelet therapy and are randomized to assume carvedilol.
Metoprolol
ACTIVE COMPARATORPatients who have documented ACS, who are on dual antiplatelet therapy and are randomized to assume metoprolol.
Interventions
Patients randomized to this group will receive carvedilol at the highest dose tolerated
Patients randomized to this group will receive metoprolol at the highest dose tolerated
