To investigate loss of systemic endothelial function post-PCI and evaluate the putative therapeutic effect of BNP. Loss of endothelial function (LEF) post-PCI may contribute to both acute and long-term complications. A protective effect of BNP on endothelium was suggested previously. Flow-mediated vasodilation (FMD) of the brachial artery, as well as plasma levels of endothelin, BNP, Pro BNP and corin were measured before and following routine PCI. 49 patients with normal baseline endothelial function were recruited. 30 patients developed LEF and were randomized to i.v. nesiritide (the commercially available recombinant form of human BNP) or saline infusion for 3 h. Patients who developed LEF post-PCI had reduced baseline plasma corin levels and their BNP/ProBNP ratio was reduced after the procedure. Nesiritide infusion significantly improved FMD both immediately (Nesiritide versus saline: 2.87±0.78% versus 0.51±0.25%, P=0.007) and 24 h after the treatment (2.52±0.69% versus 0.72±0.32%, P=0.025). The elevated plasma ET-1 was reduced by Nesiritide (0.38±0.11 fmol/ml 24 h post-PCI versus 0.16±0.02 fmol/ml 24 h post BNP, P=0.047), but remained unchanged in saline group (0.39±0.21 fmol/ml versus 0.42±0.23 fmol/ml, P=0.749). Systemic LEF post-PCI is a frequent event. It may be related to impaired cleavage of ProBNP to BNP. Short-term i.v. nesiritide improves systemic LEF post-PCI.
