Hypertension and dyslipidaemia are important components of metabolic syndrome and both are known to complicate each other. Materials and Methods. A total of 149 subjects consisting of 107 hypertensive patients, grouped into 3 (of 37, 35, and 35 patients categorized based on the grade of hypertension as grade 1, grade 2, and grade 3, resp.) and 42 controls, were recruited for this study. Each subject had a recording of the bio- and anthropometric data comprising of the age, height, weight, body mass index (BMI), and abdominal circumference (AC). The blood pressure was also recorded. Fasting blood was collected and serum was used for the estimation of the lipids: total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and triglyceride (TG), while low density lipoprotein cholesterol (LDL-C) and VLDL were estimated using Friedewald formula. Findings. Patients with hypertension had higher lipid and lipoprotein levels than the controls and the values became more significant with increasing severity of hypertension. The difference was statistically significant for TC, LDL-C, and VLDL-C (P < 0.05). Conclusion. This study showed that lipid and lipoprotein cholesterol abnormalities exist and even worsen with severity of hypertension. It is important that investigations in patients with hypertension should include a lipid profile.
高血压和血脂异常是代谢综合征的重要组成部分,且二者相互影响。材料与方法。本研究共招募了149名受试者,其中包括107名高血压患者,根据高血压分级分为3组(分别为37例、35例和35例,对应1级、2级和3级高血压)以及42名对照者。记录了每位受试者的生物和人体测量数据,包括年龄、身高、体重、体重指数(BMI)和腹围(AC)。同时记录血压。采集空腹血样,血清用于检测血脂:总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)和甘油三酯(TG),而低密度脂蛋白胆固醇(LDL-C)和极低密度脂蛋白(VLDL)则使用Friedewald公式估算。结果。高血压患者的血脂和脂蛋白水平高于对照组,且随着高血压严重程度的增加,这些值变得更加显著。TC、LDL-C和VLDL-C的差异具有统计学意义(P < 0.05)。结论。本研究表明,高血压患者存在血脂和脂蛋白胆固醇异常,且随着高血压严重程度的增加而恶化。对高血压患者进行检查时应包括血脂检测,这一点很重要。
