ACE and myocardial infarction: The mean values of left ventricular ejection fraction (LVEF), peak creatine kinase myocardial band (CK-MB), and peak troponin-I, and the number of current smokers, and the prescription rates of ticagrelor, angiotensin converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) as discharge medications, multivessel disease and patients with pre-PCI thrombolysis in myocardial infarction (TIMI) flow grade 0/1 were higher in the EI group than in DI.
