NPPB and coronary artery disorder: Serial determinations of natriuretic peptides have been proposed for prognostic assessment in CV patients[15], but still there is limited information about the within-person variability in natriuretic peptide levels over time[9], and the prognostic value of NT-proBNP among patients with stable CHD[5,16], whose frequency of follow-up examinations depends mainly on the likelihood of disease progression and the occurrence of a subsequent CVE.
