Data are presented as mean±SD or median and interquartile range. CI indicates cardiac index; EW, external stroke work; HR, heart rate; LV, left ventricular; MAP, mean arterial blood pressure; MBF, myocardial blood flow; MEE, myocardial external efficiency; MVO2, myocardial oxygen consumption; SVI, stroke volume index.
