Predictive value of leukocyte count for cardiovascular events in patients with unstable Angina pectoris / 中国介入心脏病学杂志

ABSTRACT

Objective To investigate the predictive value of peripheral leukocyte and its subtypes count on cerebral-cardiovascular events in patients with unstable angina pectoris.Methods From December 2000 to January 2003,141 patients(aged 41-84 years) with unstable angina pectoris referred for coronary angiography were enrolled and their peripheral leukocyte and its subtypes were counted.The major adverse cerebral-cardiovascular events rate of these patients during 46.2?6.6 months of follow-up were assessed.Results A total of 55 cerebral-cardiovascular nonfatal events and 8 deaths were observed.After adjusting the risk factors of diabetes mellitus,smoking,hypertension,hyperlipidemia,prior myocardial infarction,family history,and blood fibrinogen and uric acid level,leukocyte count was positively associated with cerebral-cardiovascular events(adjusted relative risk 1.31,95% CI 1.15 to 1.49).The monocyte count in patients with cerebral-cardiovascular events was higher than that in patients without cardiovascular events(P
