Change of white blood cell count more prognostic important than baseline values after primary percutaneous coronary intervention for ST elevation myocardial infarction.
Elevated baseline white blood cell (WBC) counts in patients with ST segment elevation myocardial infarction (STEMI) have been associated with increased infarct size and higher in-hospital and long-term mortality [1–6]. Persistent WBC count elevation may be an even more important predictor of a poor prognosis than a single baseline WBC count. However, the relationship between serial WBC measurements and clinical outcome in patients with STEMI is unknown. Therefore, we measured serial WBC counts, before and after
