Superiority of total white blood cell count over other leukocyte differentials for predicting long-term outcomes in patients with non-ST elevation acute coronary syndrome

Abstract

Context: Leukocytes have been found to be the predictor of outcome following acute coronary syndrome (ACS).Objective: We sought to determine the relationship between leukocyte differentials and developing major adverse cardiac events (MACE) in patients with non-ST elevation ACS (NSTE-ACS).Materials and methods: A total of 490 consecutive patients were enrolled, and MACE incidence was evaluated at long-term follow-up period.Results: Total white blood cell (WBC) was higher in subjects occurring MACE. Moreover, elevated total WBC, ≥7.5 × 103/µL, independently predicted MACE.Discussion and conclusion: Elevated admission total WBC can predict long-term MACE in NSTE-ACS patients better than other differentials.
