From: B-type natriuretic peptide trumps other prognostic markers in patients assessed for coronary disease
Kaplan Meier curves for death, myocardial infarction or stroke. Apart from coronary angiogram results, clinicians remained blinded to all other baseline risk markers. p values are a chi-squared log-rank test for trend performed at a landmark censoring of 1 year and at the median 5-year follow-up. Corresponding p values for all-cause mortality alone at 5-year follow-up are a BNP p = 0.001, b hs-CRP p = 0.27, c central augmentation pressure p = 0.38, d low/high-frequency HRV p = 0.30, e Framingham risk p = 0.026, f Angiographic coronary disease p = 0.09. *Post hoc exclusion of patients with atrial arrhythmias at baseline or follow-up had no impact on results. †Post hoc exclusion of patients with any revascularization resulted in ptrend = 0.029 for death, MI or CVA at 5-year follow-up, and 0.18 for mortality alone.
