Change in FMD
Délai: baseline and 1 month
|
The primary endpoint is the change in flow-mediated dilation (FMD) (comparison before treatment versus after treatment and stenting) in the three study groups.
The mean FMD across the three measurements (1 day, 1 week, 1 month) performed after coronary artery stenting will be compared to the FMD value before drug administration and stenting.
