Table 1. Distribution of baseline characteristics, laboratory and echocardiographic findings, and clinical outcomes classified by sex (n = 103).

χ²-test or Fisher's exact test for male vs. female; p-value was calculated by Student's t-test for continuous variables (^*p-value < 0.05). MI: myocardial infarction, APACHE II: Acute Physiology and Chronic Health Evaluation II, CK-MB: creatine kinase MB, TnI: troponin I, NT-pro BNP: N-terminal prohormone of brain natriuretic peptide, WBC: white blood cell, ESR: erythrocyte sedimentation rate, CRP: C-reactive protein, LVEF: left ventricular ejection fraction, F/U: follow up, CXR: chest X-ray, SCMP: stress-induced cardiomyopathy, ACEi/ARB: angiotensin-converting-enzyme inhibitor/angiotensin receptor blocker
