Demographic characteristics, cardiac risk factors, history, cardiac biomarkers and coronary artery disease characteristics of all patients (n=22) included in the analysis are given.
MI = myocardial infarction; CAD = coronary artery disease; CK = creatine kinase; CK MB = creatine kinase isonenzyme MB; LAD = left anterior descending coronary artery; RCX = right circumflex coronary artery; RCA = right coronary artery; STEMI = ST-segment elevation myocardial infarction; NSTEMI = non ST-segment elevation myocardial infarction. A significant coronary stenosis was defined as ≥50% stenosis (percent luminar diameter narrowing). All data collected during the first examination. †Based on core laboratory analysis of the X-ray coronary angiograms. Medications of all patients with acute myocardial infarction (n=22) are listed for time of admission and at the time of follow-up. ACE = angiotensin-converting enzyme.
