Figure 2 Cumulative probability of death in patients with (A) acute myocardial infarction (n_1–3 = 51, 57, 67) pooled log-rank p < 0.001; (B) angina or unstable angina (n_1–4 = 50, 64, 74, 44) pooled log-rank p < 0.001; (C) other cardiac causes (n_1–3 = 23, 23, 51) pooled log-rank p = 0.004; (D) other noncardiac or unknown causes (n_1–4 = 124, 76, 40, 31) pooled log-rank p < 0.001. The curves are terminated when <10 patients remain at risk. NT-proBNP = N-terminal pro brain natriuretic peptide.
