摘要
目的 研究急性冠脉综合征 (包括不稳定性心绞痛、急性心肌梗死和心源性猝死 )患者血清C 反应蛋白(CRP)浓度水平并与对照组 (即非急性冠脉综合征 ,包括稳定性心绞痛、陈旧性心肌梗死和正常体检人群 )比较 ,探讨CRP是否为急性冠脉综合征的一种危险因子。方法 用速率散射比浊法测定急性冠脉综合征患者和对照组血清CRP浓度 ,同时检测冠心病的常见危险因子并与CRP一起作Lo gistic回归分析。结果 ①急性冠脉综合征患者血清CRP浓度 [18 5 0mg/L± 2 3 98mg/L (SE 2 5 1,n =91) ]显著高于对照组 [3 89mg/L± 7 14mg/L (SE 0 5 1,n =194 ) ](P <0 0 1)。②急性心肌梗死急性期患者CRP浓度 (18 6 5mg/L± 2 4 12mg/L)和不稳定性心绞痛CRP浓度 (17 95mg/L±2 4 10mg/L)显著高于正常对照组 (P <0 0 1)、稳定性心绞痛CRP浓度 (3 94± 7 5 0mg/L) (P <0 0 1)、急性心肌梗死患者恢复期 (5 93mg/L± 13 0 7mg/L) (P <0 0 1)和陈旧性心肌梗死患者 (4 5 7mg/L± 8 2 7mg/L) (P <0 0 1) ;稳定性心绞痛患者、急性心肌梗死患者恢复期和陈旧性心肌梗死患者之间CRP浓度无差别 (P >0 0 5 )并与正常人群比较无显著性差别 (P >0 0 5 )。③每增加CRP 5mg/L ,急性冠脉综合征发生危险增加到近 2倍 (用Logistic回归 。
Objectives To assess the levels of CRP in patients with acute coronary syndrome (ACS) [including unstable angina pectoris (UAP), acute myocardial infarction (AMI) and sudden cardiac death (SCD)] compared with non ACS [including stable angina pectoris (SAP), old myocardial infarction (OMI) and healthy volunteers] and to test whether CRP are associated with clinical acute coronary syndrome. Methods Ultrasensitive immunoassay (rate nephelometry with the Beckman Immunochemistry Systems) was used to measure CRP levels in 91 patients with ACS (20 UAP, 69 AMI and 2 SCD) and 194 non ACS (34 SAP, 25 patients with healing phase of AMI, 41 OMI and 94 control healthy subjects). Results CRP levels were higher in ACS group [18 50 mg/L±23 98 mg/L (SE 2 51, n =91)] compared with non ACS group [3 89 mg/L±7 14 mg/L (SE 0 51, n =194)] ( P <0 01). Using Logistic Regression, CRP was a potent determinant of ACS (OR=1 65). Conclusions These results suggest that CRP has a strong association with ACS, and CRP is a risk factor of ACS.
