Transient increase in plasma brain (b‐type) natriuretic peptide after percutaneous transluminal coronary angioplasty

Abstract: SummaryBackground: Brain (B-type) natriuretic peptide (BNP) is known to be secreted predominantly from the myocardium. Brain natriuretic peptide plasma concentrations have been shown to be markedly increased in patients with acute myocardial infarction; however, plasma BNP response during episodes of myocardial ischemia has not been established.Hypothesis: This study was designed to examine plasma BNP in patients with transient myocardial ischemia induced by inflation of a percutaneous transluminal coronary an… Show more

“…11 Moreover, the magnitude of the increase may reflect the extent of the ischemic injury, elevations being detected soon after the onset of myocardial ischemia. 15,16 We measured NT-proBNP at a median time of 3 hours after the onset of ischemic symptoms. Such early increases may reflect the amount of the ischemic insult to the myocardium rather than the actual extent of myocardial necrosis.…”

“…A fim de confirmar esse suposto mecanismo, Tateishi e cols. 34 estudaram um grupo de pacientes submetidos a cinecoronariografia diagnóstica e compararam com outro grupo submetido a intervenções coronarianas. Embora nenhuma alteração hemodinâmica tenha sido observada, antes e depois do procedimento, o peptídeo natriurético tipo-B plasmático esteve aumentado apenas no grupo dos pacientes submetidos à intervenção coronariana.…”

“…This is in accordance with the recent report that BNP levels increase as a result of temporary occlusion of a coronary artery in conjunction with a coronary intervention, 20 even when intracardiac filling pressures remain unchanged. 21 …”
