为探讨C反应蛋白与急性冠状动脉综合征的关系及阿司匹林对其的影响 ,观察 46例急性心肌梗死患者、40例不稳定性心绞痛患者及 42例稳定性心绞痛患者的C反应蛋白浓度以及不同剂量的阿司匹林对心肌梗死患者C反应蛋白浓度的影响。结果发现心肌梗死及不稳定性心绞痛患者的C反应蛋白浓度较稳定性心绞痛患者显著增高 (P <0 .0 0 1)。小剂量 (每天 30 0mg)阿司匹林可降低心肌梗死患者的C反应蛋白浓度 (P <0 .0 5 )。提示C反应蛋白浓度可作为评价急性冠状动脉综合征患者预后的一个参考指标。 In order to investigate the relationship between C-reactive protein and acute coronary syndrome and the effect of aspirin on C reactive protein in 46 patients with acute myocardial infarction, 40 patients with unstable angina and 42 patients with stable angina, Effect of Aspirin on C-reactive Protein in Patients with Myocardial Infarction. The results showed that patients with myocardial infarction and unstable angina C-reactive protein concentrations were significantly higher than those of patients with stable angina (P <0.01). Small doses of aspirin (30 0 mg daily) decreased C-reactive protein levels in patients with myocardial infarction (P <0.05). Tip C-reactive protein concentration can be used as a prognostic indicator in patients with acute coronary syndrome.
