Table 3

Outcomes in the pre- and postinitiative patient populations. MACE is major adverse cardiac events (myocardial infarction, unstable angina, cardiovascular death, revascularization, fatal/nonfatal cerebrovascular accident, peripheral arteriopathy, aortic event), EF: ejection fraction measured at discharge.
