Abstract:
Quantitative serial coronary angiograms performed annually over a 3-year period after transplantation in 26 orthotopic heart transplant recipients showed persistently normal nitroglycerin-induced vasodilation. The vasodilator response to nitroglycerin did not predict development of graft arteriopathy; the presence of graft arteriopathy did not prevent a substantial vasodilator response to nitroglycerin.
