Purpose
The aim of this study is to investigate usefulness of the respirophasic variation in carotid artery peak flow velocity measured by Doppler ultrasound, which is noninvasive and easily accessible, as a predictor of fluid responsiveness in patients with coronary artery disease.

Primary Outcome Measures:
- Predictive power of the respirophasic carotid flow peak velocity variation for the fluid responsiveness [ Time Frame: Measurement of respirophasic carotid flow peak velocity variation before the volume expansion ]After induction of anesthesia, peak velocity of carotid artery blood flow is measured by the pulsed wave Doppler signal obtained from the left common carotid artery. Respirophasic variation of the peak velocity is defined as the difference between the maximum and the minimum values of peak velocity divided by the mean of the two values during one respiratory cycle. Fluid responder is defined as a patient whose stroke volume index is increased ≥15% after volume expansion. The receiver operating characteristic curve analysis to descriminiate fluid responder is performed.
