Clinicians should carefully consider a patient's renal function when determining the timing and dosage of initial ACE inhibitor therapy. ACE inhibitor therapy should be administered early after CABG in patients who have had a recent MI, as well as in those who have left ventricular dysfunction, diabetes mellitus, and/or chronic kidney disease.

Unless contraindicated, beta-blockers should be administered as close as possible to the time of CABG to reduce the risk for postoperative atrial fibrillation and to facilitate blood pressure control early after surgery.

Treatment with an aldosterone antagonist that is licensed for post-MI treatment is recommended for patients who have had an acute MI and who have symptoms and/or signs of heart failure and left ventricular systolic dysfunction. Treatment should be initiated within 3 to 14 days of the MI, preferably after ACE inhibitor therapy.
