直立倾斜试验与卧立位试验对老年高血压患者体位性低血压的检出效果比较

Comparison of the detection results of head-up tilt test and recumbent-upright test on orthostatic hypotension in elderly hypertensive patients

目的比较直立倾斜试验与卧立位试验对老年高血压患者体位性低血压的检出效果。方法选取2017年2月至2018年6月于扬州大学附属医院就诊的80例老年高血压合并体位性低血压患者,采用随机数表法分为倾斜组和卧立组,每组40例。比较两种方法对体位性低血压的检测率及试验后不良事件发生率。结果倾斜组和卧立组体位性低血压检出率分别为45.0%(18/40)、20.0%(8/40).倾斜组体位性低血压检出率较卧立组高,差异有统计学意义(P<0.05)。倾斜组和卧立组试验后不良事件总发生率分别为0、15.0%(6/40)。倾斜组患者试验后不良事件总发生率较卧立组低,差异有统计学意义(P<0.05)。结论直立倾斜试验对老年高血压患者体位性低血压检出率较高,且可减少检查相关不良事件的发生。

Objective To compare the detection results of head-up tilt test and recumbent-upright test on orthostatic hypotension in elderly hypertensive patients. Methods Eighty elderly patients with hypertension and orthostatic hypotension who were admitted to the Affiliated Hospital of Yangzhou University from February 2017 to June 2018 were enrolled. The patients were divided into tilt group and recumbent-upright group by random number table, 40 cases in each group. The detection rate of orthostatic hypotension and the incidence of adverse events after the test were compared between the two methods. Results The detection rates of orthostatic hypotension in tilt group and recumbent-upright group were 45.0%(18/40) and 20.0%(8/40), respectively. The detection rate of orthostatic hypotension in tilt group was higher than that in recumbent-upright group, and the difference was statistically significant(P<0.05). The total incidence of adverse events after the test in tilt group and recumbent-upright group was 0, 15.0%(6/40), respectively. The total incidence of adverse events in tilt group was lower than that in recumbent-upright group, and the difference was statistically significant(P<0.05).Conclusion The head-up tilt test has a higher detection rate of orthostatic hypotension in elderly hypertensive patients and could reduce the occurrence of examination-related adverse events.
