Sd. Correa et S. Schaefer, BLOCKADE OF K-ATP CHANNELS WITH GLIBENCLAMIDE DOES NOT ABOLISH PRECONDITIONING DURING DEMAND ISCHEMIA, The American journal of cardiology, 79(1), 1997, pp. 75
The role of adenosine triphosphate-sensitive potassium channels in the
adaptive response to demand ischemia was tested in 22 patients treate
d with placebo or glibenclamide before sequential exercise testing or
atrial pacing, Glibenclamide did not affect the improvement in signs o
f ischemia in both protocols, indicating that opening of these channel
s is not a mechanism of this adaptive response in humans.
