Brief Summary:
This study is aimed to evaluate the association of common carotid artery circumferential strain with the echocardiographic parameters of left ventricular function and the degree of actual hemodynamic deterioration in patients undergoing multi-vessel off-pump coronary artery bypass with preserved left ventricular ejection fraction.

Primary Outcome Measures :
  1. TTE parameters [ Time Frame: 1 day before the surgery ]
    TTE parameters: left ventricular ejection fraction, left atrial volume index, left ventricular mass, Sm, Em, E/Em

Secondary Outcome Measures :
  1. change of intraoperative hemodynamic variables [ Time Frame: from after induction of anesthesia, left circumflex artery grafting, and to sternum closure ]
    TTE parameters: left ventricular ejection fraction, left atrial volume index, left ventricular mass, Sm, Em, E/Em Carotid circumferential strain : Storage of transverse image of the right CCA at approximately 1cm proximal to the bifurcation, manual trace of luminal-intimal border and automatic tracking by frame-to-frame movement of ultrasound reflections (speckles) Hemodynamic variables: cardiac index and mixed venous oxygen saturation obtained from the pulmonary artery catheter and cardiac output monitoring devices
