目的探讨高血压病患者的动态血压与左心室肥厚的关系。方法对100例原发性高血压患者进行24小时动态血压监测(ABPM)检查,计算24小时全天、白天、夜间平均血压及血压负荷值和血压昼夜节律变化情况,同时行超声心动图检查将患者分为左心室肥厚(LVH)和无左心室肥厚两组。结果两组患者在血压昼夜节律、血压均值、血压负荷值均有显著差异(P<0.05)。结论高血压病患者血压昼夜节律的消失及血压负荷值的增高与左心室肥厚密切相关。
Objective To investigate the relationship between ambulatory blood pressure and left ventricular hypertrophy in patients with essential hypertension. Methods A total of 100 patients with essential hypertension underwent 24-hour ambulatory blood pressure monitoring (ABPM). The changes of mean blood pressure, blood pressure load, and circadian rhythm of blood pressure during 24 hours, daytime and nighttime were calculated. Echocardiography Patients were divided into two groups: left ventricular hypertrophy (LVH) and left ventricular hypertrophy. Results The two groups of patients had significant differences in blood pressure circadian rhythm, mean blood pressure and blood pressure load (P <0.05). Conclusion The disappearance of circadian rhythm of blood pressure and the increase of blood pressure load in hypertensive patients are closely related to left ventricular hypertrophy.
