Risk for all‐cause mortality and MI. Adjusted for age, history of DM, prior MI, prior CHF, ST‐segment deviation (>1 mm), CrCl, NT‐pro‐BNP (>80 pg/mL), current smoking, and Killip class (I vs II–IV). ∗︁ = The interval increased HR for all‐cause mortality in the fourth quartile of catalytic iron was statistically significant (P = 0.036). Abbreviations: CHF, congestive heart failure; CrCl, creatinine clearance; CV, cardiovascular; DM, diabetes mellitus; HR, hazard ratio; NT‐pro‐B‐type natriuretic peptide, N terminal pro‐B‐type natriuretic peptide; MI, myocardial infarction.
