Relationship between white blood cell count and the prognosis in patients with non-ST elevation acute coronary syndromes (NSTACS).

Objective To evaluate the predictive value of white blood cell count (WBC) for the hospital and six months mortality in patients with non-ST elevation acute coronary syndromes (NSTACS) . Methods 348 consecutive patients with NSTACS were enrolled. Patients were stratified according to quartiles of WBC determined on admission. Results The first quartile of WBC was6.8×10 9/L, the second quartile was 6.8～8.0×10 9/L, the third quartile was 8.0～10.0×10 9/L, and the fourth quartile was 10.0×10 9/L.The death rate in the fourth quartile was higher than the other quartiles in the hospital and at 6 months (P=0.003 and P0.001 ). Conclusions: WBC is a economic and convenient independent predictor of outcomes in patients with NSTACS.
