阿司匹林对老年冠心病患者血清C反应蛋白水平的影响

目的观察老年冠心病患者（CHD）组）血清C反应蛋白（CRP）水平及应用不同剂量阿司匹林治疗后其血清CRP水平的变化。方法将90例老年冠心病患者随机分为阿司匹林100mg／d组（CHD1组）、150mg／d组（CHD2组）、200mg／d（CHD3组），另设正常对照组（对照组），每组均为30例。测定对照组及90例冠心病患者应用阿司匹林治疗前和治疗后12周时的血清CRP水平。结果CHD组的CRP水平较对照组明显升高（P〈0．05），CH）2组、CHD3组经阿司匹林治疗后血清CRP水平较CHD1组明显降低（P〈0．05）。结论老年冠心病患者血清CRP水平升高，阿司匹林干预治疗可降低冠心病患者血清CRP水平，提示冠心病的发生发展过程与炎症有关，而阿司匹林可呈剂量相关地通过抗炎作用抑制其进展，效应以150mg以上为佳。

Serum C-reactive protein levels in elder patients with coronary heart disease and effect of aspirin intervention

Objective To investigate the serum C-reactive protein(CRP) concentrations in elder patients with coronary heart disease(CHD) and the change of serum CRP concentrations in patients with CHD treated with aspirin.Methods Ninety elder patients with CHD were administered aspirin at the dose of 100mg/d(CHD1 group),150mg/d(CHD2 group),200mg/d(CHD3 group).Normal subjects were selected as control(control group),there were thirty subjects in each group.The detected parameters included serum CRP concentrations for 0 and 12 weeks.Results CRP concentration in patients with coronary heart disease was significantly higher than that of the normal subjects(P<0.05).CRP concentration in patients with CHD could reduce with aspirin 150mg/d,200mg/d for 12 weeks(P<0.05).Conclusion The serum CRP concentration is associated with patients with CHD,the serum CRP concentration could reduced with bigger dosage of aspirin.The occurance and development of CHD is correlative to inflammation,aspirin could dose-dependantly attenuate the progression of CHD.
