文摘
- •
Dobutamine dose > 20 μg/kg/min induced maximal hyperemia much like adenosine.
- •
Dobutamine-induced hyperemia is equivalent to adenosine-induced one only in patients with myocardial ischemia.
- •
CFVR during inotropic stimulation provides more reliable functional evaluation of MB.
- •
MB decompression is slow and incomplete, and reaches its maximum at mid-diastole.
- •
MB compression at mid-to-end-diastole is higher in patients with myocardial ischemia.
