Prognostic value of baseline white blood cell count in patients with acute myocardial infarction and ST segment elevation

In the setting of an acute myocardial infarction (AMI), elevated white blood cell count (WBC-C) has been associated with adverse cardiovascular events 1- 3 implying not only a purely reparative physiological role, but a pathologic one. [...]WBC-C has recently drawn the attention of researchers as a potential stratification tool because of its simplicity, cost effectiveness, and wide availability. In multivariate analysis (adjusted by age, sex, Killip class, new onset bundle branch block, clinical evidence of reperfusion, systolic blood pressure, and serum creatinine) WBC-2 was associated with a twofold increase in the incidence of death at 30 days (HR 2.21, 95% CI 1.13 to 4.31) and one year (HR 2.16, 95% CI 1.27 to 3.7) compared with WBC-1.
