text: <unk><unk>  can be induced by percutaneous<unk>  intervention (PCI) secondary to endothelial denudation and nitric oxide loss.

The initial treatment is intracoronary vasodilatation with calcium channel blockers and/or nitrates, which should be given slowly when using guiding catheters.  Therapies for<unk>  will usually take effect within seconds to one minute.
