白细胞计数与非ST段抬高急性冠状动脉综合征患者的预后关系

目的　研究白细胞计数 (WBC)与非 ST段抬高急性冠状动脉综合征 (NSTACS)患者预后的关系。方法　 348例非ST段抬高急性冠状动脉综合征患者入选 ,并进行冠状动脉造影以确定治疗方法。根据入院时的白细胞计数按照四分位法将患者分成四组。结果　各组的白细胞计数分别是 <6 .8× 10 9/ L,6 .8～ 8.0× 10 9/ L,8.0～ 10 .0× 10 9/ L 和 >10 .0× 10 9/ L。第四组的患者在住院期间和随访期间的死亡率明显高于其他三组 ,P=0 .0 0 3和 P<0 .0 0 1。结论　白细胞计数是一项经济和方便的预后指标 ,可用于判断非 ST段抬高急性冠状动脉综合征患者的预后。

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 was<6.8×10 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 P<0.001 ). Conclusions: WBC is a economic and convenient independent predictor of outcomes in patients with NSTACS.
