The value of N-terminal fragment of brain natriuretic peptide and tissue inhibitor of metalloproteinase-1 levels as predictors of cardiovascular outcome in the LIPID study

Aims We sought to determine the association between two major biomarkers, the inactive N-terminal fragment of brain natriuretic peptide (NT-proBNP) and tissue inhibitor of metalloproteinase-1 (TIMP-1) and long-term cardiovascular outcomes in a cohort of subjects who had a myocardial infarction or unstable angina 3–36 months previously. Methods and results Plasma NT-proBNP and TIMP-1 were measured in a nested case control study of 250 randomly matched subject pairs enrolled in the long-term intervention with pravastatin in ischaemic disease (LIPID) and LIPID extended follow-up studies. Cases ( n = 250) were defined as those who had a cardiovascular death, non-fatal myocardial infarction or s…
