  • Title: Plasma N-terminal atrial natriuretic peptide in acute myocardial infarction.
    Author: Kettunen RV, Leppäluoto J, Jounela A, Vuolteenaho O.
    Journal: Am Heart J; 1994 Jun; 127(6):1449-55. PubMed ID: 8197967.
    Abstract:
    Plasma atrial natriuretic peptide (ANP) and the N-terminal (NT) fragment of the 126-amino acid prohormone of ANP (proANP; NT-proANP) were correlated with clinical findings in 41 patients with acute myocardial infarction and in 19 patients with angina pectoris. On admission to the hospital, the 39 patients with nonfatal infarction who subsequently had overt heart failure (n = 8) had plasma NT-proANP (2374 +/- 1038 pmol/L) and ANP (54 +/- 43 pmol/L) concentrations that were higher (p < 0.01) than those in the patients who remained without or who presented with minor signs of failure. In contrast to the relatively stable NT-proANP levels, ANP decreased markedly during the first 24 hours in the patients who had any signs of failure. Hence the plasma levels of NT-proANP and ANP did not go hand in hand in acute myocardial infarction, and NT-proANP appeared to be a better marker of cardiac dysfunction than ANP.
