24小时动态血压监测对中青年高血压病诊断探讨

Study on Diagnosing Hypertension by Ambulatory Blood Pressure Monitoring of 24 Hours in the Youth and Meddle age

目的 :探讨24h动态血压监测(24hABPM)对中青年正常血压及高血压分级的诊断参数以及24h血压波动规律的应用价值。方法 :采用无创性携带式动态血压监测仪检测20例正常中青年人及172例中青年高血压患者的动态血压(ABP)。根据WHO/ISH标准进行分极 ,172例中 ,高血压Ⅰ级52例 ,Ⅱ级60例 ,Ⅲ级60例 ,将24hABPM提供的血压参数进行统计学处理 ,并对血压波动规律进行分析。结果 :正常血压组与高血压组血压波动规律相同 ,即白天血压增高 ,夜间血压下降 ,血压水平越高 ,血压的波动范围越大。高血压各组与正常血压组比较血压均值参数有显著的差异性(P<0 01)。结论

Objective: To explore the application value of the diagnosis, grading of hypertension and blood pressure's waving rules in the youth and middle age using ambulatory blood pressure (ABP) monitoring of 24 hours. Methods: 20 cases of age-matched people were studied as a control group. 172 cases of young and middle age patients with hypertension underwent ABP monitoring. According to the criteria of WHO/ISH to grade, among the 172 patients there are 52 cases in grade NO.1, 60 cases in No.2, and 60 cases in No.3. All blood pressure indexes were analyzed with statistics. Results: The rules of blood pressure change in the control and hypertension groups were similar. Blood pressures of both groups were down at nighttime and up on daytime. The higher blood pressure was, the more change was. Compared with the control, the indexes in the patients were significant different (p<0.01). Conclusions: There was an important value to use 24-hour ABP monitoring for funding early hypertension, diagnosing different grade of hypertension and understanding the changing rules and range of 24-hour ABP.
