目的探讨单纯无明显心脏器质性病变的高血压患者ST-T改变与血脂的关系。方法以单纯无明显心脏器质性病变的高血压病患者为研究对象,按心电图表现分为ST-T改变组(57例)和无ST-T改变组(41例),检测两组患者的血糖,血脂水平。结果与无ST-T改变组相比,ST-T改变组血清总胆固醇水平明显增高,而高密度脂蛋白水平则明显降低(P<0.05),其他检测指标在两组无显著性差异。结论在血脂正常且无明显心脏器质性病变的高血压患者中,相对较高的总胆固醇水平促使或加重心肌缺血,而高密度脂蛋白对心肌损害起着保护作用。
Objective To investigate the relationship between ST-T changes and serum lipids in hypertensive patients with simple heart disease. Methods Patients with essential hypertension without obvious cardiac organic disease were divided into two groups: ST-T group (57 cases) and ST-T group (41 cases) Blood sugar, blood lipid levels. Results Compared with no ST-T change group, serum total cholesterol level was significantly increased and HDL level was significantly decreased in ST-T change group (P <0.05). Other test indexes had no significant difference between the two groups. Conclusions In hypertensive patients with normal blood lipids and no obvious organic disease, relatively high total cholesterol levels promote or aggravate myocardial ischemia, whereas HDL plays a protective role in myocardial damage.
