Clinical Presentation, Heart Function, Incidence of Mechanical Supports, and 30-Day Clinical Outcome among 309 Patients.

Data are expressed as % (n) or mean ± SD. *Group 1 = angina pectoris, Group 2 = unstable angina, Group 3 = non ST-segment elevation myocardial infarction, Group 4 = post-ST-segment elevation myocardial infarction angina. †defined as congestive heart failure (CHF) ≥ New York Heart Association Functional Classification (Fc) III. ‡measured upon presentation. §intra-aortic balloon pump (IABP) was used for hypotension/shock. ¶indication for poor left ventricular function [i.e., left ventricular function (LVEF) <35%], pulmonary edema, or hypotension/cardiogenic shock. ξextra-corporeal membrane oxygenator (ECMO) was used for profound cardiogenic shock. δindicated measurement of LVEF by transthoracic echocardiography. Letters (a,b) indicate significant difference (at 0.05 level) by Bonferroni multiple-comparison post hoc test.
