目的:探讨老年原发性高血压患者血压晨峰与心血管事件风险的相关性。方法:采用动态血压监测仪分析230例老年高血压患者的血压,分为晨峰组与非晨峰组,测定心电图和超声心动图。结果:与非晨峰组相比较,晨峰组凌晨收缩压、脉压较高,QT离散度增大,差异均有统计学意义(P<0.01);晨峰组的左室肥厚发生率为56.8%,非晨峰组为42.5%,差异有统计学意义。结论:血压晨峰使心血管事件的风险增加。
Objective: To investigate the correlation between the peak of blood pressure and the risk of cardiovascular events in elderly patients with essential hypertension. Methods: The blood pressure of 230 elderly hypertensive patients was analyzed by ambulatory blood pressure monitor. The blood pressure was divided into morning climax group and non-morning climax group, and the electrocardiogram and echocardiogram were measured. Results: Compared with the non-morning peak group, systolic blood pressure, high pulse pressure and QT dispersion increased significantly in the morning peak group (P <0.01), and the incidence of left ventricular hypertrophy in the morning peak group was 56.8%, non-morning peak group was 42.5%, the difference was statistically significant. Conclusion: Morning blood pressure increases the risk of cardiovascular events.
