West et al.1 report a small, well designed post hoc nested case–control sample from the LIPID trial of pravastatin.2 This was completed in low risk subjects with documented coronary disease in the form of a previous confirmed acute coronary syndrome (ACS). This additional report examines biomarker linkage over a relatively short time frame of 2–3 years and highlights two measurements perhaps not intuitively linked to the biology of coronary disease progression. The conditional logistic regression analysis shows a significant linkage association following point analysis for N-terminal brain natriuretic peptide (NT-BNP) and tissue metalloproteinase-1 (TIMP-1). TIMP-1 has been linked to cardiovascular events in low risk patients previously, in patients with less well confirmed coronary disease.3 Its re-affirmation here as a population predictor of events in this group of patients is of value. Similarly for NT-BNP, which is frequently presumed
