2018原发性高血压患者血脂综合指数与左心房大小的相关性研究
[摘要]目的 探讨原发性高血压患者血脂综合指数与左心房大小的相关性。方法 选择2014年5月~2016年4月在我院接受治疗的原发性高血压患者200例,根据经胸超声心动图检查结果分为左心房增大组70例及左心房正常组130例。测量患者肾功能、血脂、血压、空腹血糖、血脂综合指数等指标并进行统计分析,采用Spearman进行相关性分析,多变量线性回归分析左心房增大的相关因素。结果 两组血脂综合指数差异有统计学意义(P http://[关键字]原发性高血压;高血压;血脂综合指数;左心房;相关性

Objective To investigate the correlation between lipid comprehensive index and left atrial size in patients with essential hypertension.Methods From May 2014 to April 2016,200 patients with essential hypertention whose data were complete in our hospital were selected.According to the results of transthoracic echocardiography,the patients were divided into case atrial enlargement group(70 cases)and left atrial normal group(130 cases),The renal function, blood lipid,blood pressure, fasting blood glucose,blood lipid comprehensive index and other indicators were measured and statistically analyzed.Spearman was used for correlation analysis,and multivariate linear regression was used for the analysis of relevant factors of left atrial enlargement.Results In blood lipid comprehensive index between the two groups,the difference was statistically significant(P0.05),具有可比性。所有患者均签订知情同意书并经相关医学伦理委员会批准。 1.2 方法
1.2.1血液检测 入选患者空腹12 h后,抽取静脉血2~3 ml,由日式7170A全自动生化分析仪进行血脂、血糖、生化等化验分析,并计算血脂综合指数=总胆固醇×三酰甘油×低密度脂蛋白胆固醇/高密度脂蛋白胆固醇。
1.2.2血压测量 高血压的测量和诊断标准按2010年中国高血压防治指南:血压值持续或非同日3次以上超过标准血压诊断标准,即收缩压≥140mmHg(18.6 kPa)和(或)舒张压≥90 mmHg(12 kPa)者,或正在服用降压药物。
1.2.3 颈动脉的测量 采用美国产的GEVivid7彩色多普勒超声诊断仪, 探头频率2.5~3.5 MHz,由B超室专职医师操作,受检者在平静状态下取仰卧位及左侧卧位,取胸骨旁长轴、短轴切面以及心尖四腔切面记录患者的超声心动图图像,分别测量左心房内径,左心室舒张和收缩末期内径,室间隔厚度,左心室壁厚度,射血分数。其中定义左心房≥4 mm为左心房增大。
1.3统计学方法
采用统计学软件SPSS 22.0分析数据,计量资料以均数±标准差(x±s)表示,采用t检验,计数资料以率表示,采用χ2检验,以P0.05),而血脂综合指数两组间差异有统计学意义(P [参考文献]
