摘要
目的探讨血清载脂蛋白A5(ApoA5)水平与急性冠状动脉综合征(ACS)患者血脂谱及高敏性C反应蛋白(hs—CRP)的关系。方法入选587例受试对象,分为对照组(n=232)、稳定性心绞痛(SA)组(n=127)、不稳定性心绞痛(UA)组(n=116)和急性心肌梗死(AMI)组(n=112)。抽血分离血清,分别采用ELISA法和免疫比浊法测定血清ApoA5以及hs—CRP,并测定血清甘油三酯(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)和低密度脂蛋白胆固醇(LDL—C)。比较各组ApoA5、hs—CRP和血脂的血清浓度差异,分析三者之间的相互关系。结果UA组[(340.6±63.5)μg/L]和AMI组[(373.2±73.8)μg/L]的ApoA5浓度明显高于对照组[(108.7±23.2)μg/L]和sA组[(78.3±20.2)μg/L](均P〈0.05)。UA组和AMI组的ApoA5与TG(r=0.63和0.67,P〈0.05)和hs—CRP(r=0.57和0.55,P〈0.05)呈正相关,而ApoA5与TC、HDL-C和LDL—C无明显相关(P〉0.05)。结论ACS患者中血清ApoA5浓度显著升高,与血清TG或hs—CRP浓度显著正相关,提示ApoA5的代谢和生理功能在ACS期间均发生了变化,这可能与炎症反应增强有关。
Objective To explore the relationship between serum apolipoprotein A5 (ApoA5) and lipid profile or high sensitive C-reactive protein (hs-CRP) in patients with acute coronary syndrome (ACS). Methods Serum apoA5 and hs-CRP levels were measured by ELISA and immunoturbidimetry in control subjects (n = 232), patients with stable angina (SA, n = 127), unstable angina (UA, n = 116) and acute myocardial infarction (AMI, n = 112). Tfiglyeefide (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were also measured. Results Compared with controls [ (108.7 ±23.2) μg/L] and SA patients [ (78.3 ±20. 2) μg/L], serum ApoA5 level was significantly increased in UA [ (340. 6 ±63.5 ) μ/L] and AMI patients [ ( 373.2 ±73.8 ) μg/L] ( all P 〈 0. 05 ). ApoA5 was positively correlated with TG ( r = 0. 63 and 0. 67, respectively, all P 〈 0. 05 ) and hs-CRP ( r = 0. 57 and 0. 55, respectively, all P 〈 0. 05 ) in UA and AMI patients but there were no significant correlations between ApoA5 and TC, HDL-C and LDL-C in ACS patients ( all P 〉 0. 05 ). Conclusion Increased serum apoA5 level and the positive correlation between ApoA5 and serum TG and hs-CRP in ACS patients might reflect increased inflammation responses in ACS patients.
