摘要:

目的 探讨阿托伐他汀钙片对心肌梗死患者小而密低密度脂蛋白胆固醇(sd-LDL-C)的影响。方法 检测96例心肌梗死患者治疗前、采用阿托伐他汀钙片治疗4周后及50名体检健康者(正常对照组)血清总胆固醇(TC)、三酰甘油(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)及sd-LDL-C水平。根据冠状动脉电子计算机断层扫描(CT)结果将心肌梗死患者按冠状动脉狭窄程度分为狭窄<50%组、狭窄50%~70%组、狭窄>70%组。结果 与正常对照组比较,心肌梗死组血压、TG、LDL-C、sd-LDL-C、sd-LDL-C/LDL-C比值明显升高(P<0.05),HDL-C明显降低(P<0.05)。2个组之间TC差异无统计学意义(P>0.05)。狭窄<50%组、狭窄50%~70%组、狭窄>70%组TC、sd-LDL-C、sd-LDL-C/LDL-C比值依次升高(P<0.05、P<0.01),其他指标各组间差异均无统计学意义(P>0.05)。Logistic回归分析显示,TC、sd-LDL-C、sd-LDL-C/LDL-C比值是冠状动脉狭窄>70%的心肌梗死患者的危险因素[比值比(OR)值分别为2.680、2.000、7.819,95%可信区间(CI)分别为1.780~7.030、1.103~3.681、1.430~40.263]。狭窄>70%组心肌梗死患者治疗后血清sd-LDL-C、sd-LDL-C/LDL-C比值明显低于治疗前(P<0.05),而狭窄<50%组和狭窄50%~70%组患者治疗前、后差异无统计学意义(P>0.05)。结论 sd-LDL-C及sd-LDL-C/LDL-C比值可作为心肌梗死患者冠状动脉狭窄严重程度的危险因素。阿托伐他汀钙片可有效降低sd-LDL-C水平和sd-LDL-C/LDL-C比值。

Abstract:

Objective To investigate the change of small and dense low-density lipoprotein cholesterol (sd-LDL-C) in myocardial infarction patients and the level change of sd-LDL-C after taking atorvastatin calcium tablets. Methods The levels of total cholesterol (TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C) and sd-LDL-C in 96 patients with myocardial infarction before treatment and after treatment with atorvastatin calcium tablets orally for 4 weeks and 50 healthy subjects (healthy control group) were determined. Coronary computed tomography (CT) was used to determine the degree of coronary stenosis. The patients with myocardial infarction were classified into 3 groups according to the coronary CT results (<50%,50%-70% and >70%). Results Compared to healthy control group,blood pressure,TG,LDL-C,sd-LDL-C and sd-LDL-C/LDL-C ratio in myocardial infarction group were increased (P<0.05),and HDL-C was decreased (P<0.05). There was no statistical significance for TC between the 2 groups (P>0.05). TC,sd-LDL-C and sd-LDL-C/LDL-C ratios were increased in turn in coronary stenosis <50%,50%-70% and >70% groups (P<0.05,P<0.01),and other indicators had no statistical significance (P>0.05). Logistic regression analysis showed that TC,sd-LDL-C and sd-LDL-C/LDL-C ratio were risk factors for coronary stenosis>70% [odds ratios (OR) were 2.680,2.000 and 7.819,95% confidence intervals (CI) were 1.780-7.030,1.103-3.681 and 1.430-40.263]. In coronary stenosis>70% group,sd-LDL-C and sd-LDL-C/LDL-C ratio after treatment were lower than those before treatment (P<0.05),and there was no statistical significance for coronary stenosis <50% and 50%-70% groups (P>0.05). Conclusions Sd-LDL-C and sd-LDL-C/LDL-C ratio can be used as risk factors for myocardial infarction. The atorvastatin calcium tablets can decrease sd-LDL-C and sd-LDL-C-c/LDL-C ratio effectively.
