    Abstract:
    BACKGROUND: Previous studies have demonstrated that cardiac medical therapy is associated with improved clinical outcomes in noncardiac surgery. However, the use of these agents among patients undergoing coronary artery bypass graft (CABG) remains poorly understood. METHODS: We described the in-hospital medication use among 2,389 consecutive patients who underwent CABG at three North American hospitals. Demographic, clinical, and medication use information was extracted from resource and cost accounting systems at each hospital. We examined use of aspirin, angiotensin-converting-enzyme (ACE) inhibitors, beta blockers, and statins during the following seven in-hospital periods: admission, presurgery, the day before surgery, the day of surgery, the day after surgery, postsurgery, and discharge. RESULTS: Medication use throughout hospitalization was low among patients undergoing CABG. Use of ACE inhibitors and statins on the day of surgery was <10%, while aspirin and beta blocker use on the day of surgery was 43.0% and 42.9%, respectively. The use of cardiac medical therapy at hospital discharge was also low (ACE inhibitors: 23.0%; aspirin: 74.9%; beta blockers: 58.9%; and statins: 28.2%). The use of cardiac medical therapy at discharge appeared to increase over time. CONCLUSION: In-hospital cardiac medical therapies are underused among patients undergoing CABG. This is particularly true at discharge, where the benefits of these agents for secondary prevention are well established.
