these studies demonstrate that the effects of dilatation of the normal artery are partially reversible , suggest that restenosis after angioplasty is more likely to be due to intimal proliferation than increased arterial stiffness , and suggest that vasospasm of arteries after long-term recovery from the dilation is more likely to be mediated by serotonin than by norepinephrine .
