Baseline characteristics. ACEi =  angiotensin-converting-enzyme inhibitor; ARB =  angiotensin II receptor blocker; ASA =  acetylsalicylic acid; CAD =  coronary artery disease; NSTEMI =  non-ST-elevation myocardial infarction; PCI =  percutaneous coronary intervention; STEMI =  ST-elevation myocardial infarction. Here, ACE is linked to ST Elevation Myocardial Infarction.
