不同剂量阿托伐他汀治疗急性冠状动脉综合征对可溶性CD105、高敏C反应蛋白及心率震荡的影响

目的 通过观察血清可溶性CD105.(sCD105)、高敏C反应蛋白(hs-CRP)及心率震荡参数的变化,探讨阿托伐他汀强化治疗急性冠状动脉综合征(ACS)的效果及意义.方法 将106例ACS患者按随机数字表法分为治疗1组(38例,常规治疗+阿托伐他汀20 mg)、治疗2组(38例,常规治疗+阿托伐他汀40mg)和对照组(30例,仅给予常规治疗),测定三组治疗前及治疗4周后的心率震荡参数及sCD105、hs-CRP水平,并进行比较.结果 治疗前三组震荡初始(TO)、震荡斜率(TS)、sCD105、hs-CRP比较差异无统计学意义(P＞0.05).治疗后三组TO、sCD105、hs-CRP均明显下降,TS明显升高(P＜0.05或＜0.01),而治疗2组改变最显著,治疗后治疗2组上述指标与治疗1组比较差异均有统计学意义[TO比较:(0.22±0.18)%比(0.66±0.23)%;TS比较:(6.22±0.83)ms/RR间期(RRI)比(3.90±0.73)ms/RRI;sCD105比较:(1.65±0.43)mg/L比(2.92±0.50)mg/L;hs-CRP比较:(1.68±0.55)mg/L比(2.08±0.61)mg/L](P＜0.01).相关分析表明,sCD105、hs-CRP水平与TO呈显著正相关(P＜0.01),而与TS呈显著负相关(P＜0.01).结论 ACS患者给予阿托伐他汀治疗,可稳定冠状动脉血管内皮及粥样斑块,改善自主神经功能,大剂量应用更能获益.

Abstract：

Objective To investigate the clinical effects and significance of different-dose atorvastatin on soluble CD105(sCD105),high sensitive-C reactive protein(hs-CRP)and the parameters of heart rate turbulence in patients with acute coronary syndrome(ACS). Methods One hundred and six ACS patients were divided into three groups by random digits table: control group(30 patients, routine treatment),treatment group Ⅰ(38 patients, routine treatment + atorvastatin 20 mg), and treatment group Ⅱ(38patients, routine treatment + atorvastatin 40 mg). All patients were treated for 4 weeks. The levels of serum sCD105,hs-CRP,and the parameters of heart rate turbulence before and after treatment. Results Before treatment, the levels of turbulence onset(TO), turbulence slope(TS),sCD105 and hs-CRP in three groups had no significant difference(P ＞ 0.05). After treatment, TO,sCD105 and hs-CRP decreased significantly,and TS increased significantly(P＜ 0.05 or ＜ 0.01). The change amplitude of treatment group Ⅱ was the most obvious, and the levels of above mentioned index showed significantly difference compared with that of treatment group Ⅰ[TO:(0.22 ±0.18)% vs.(0.66 ± 0.23)%;TS:(6.22 ±0.83)ms/RR interval(RRI)vs.(3.90 ±0.73)ms/RRI;sCD105:(1.65 ±0.43)mg/L vs.(2.92 ±0.50)mg/L;hs-CRP:(1.68 ±0.55)mg/L vs.(2.08±0.61)mg/L](P ＜0.01). Correlation analysis showed the levels of sCD105 and hs-CRP had significantly positive correlation with TO(P ＜ 0.01)and had negative correlation with TS(P ＜ 0.01).Conclusions The atorvastatin treatment in patients with ACS may stabilize coronary vascular endothelial cells and atherosclerotic plaque, and improve autonomic nerve function. Larger doses of atorvastatin may get more benefit.
