目的:比较诊室血压及动态血压诊断高血压的符合率。方法:入选151例诊室血压≥140/90mmHg的患者,监测其24h动态血压,计算每例患者血压参数并进行统计学分析。结果:诊室收缩压、舒张压、脉压均高于动态血压全天、白天以及夜间的平均收缩压、舒张压、脉压,P<0.01;而且诊室血压高于24h动态血压中任一时点的平均血压。诊室高血压患者只有42.4%(64/151例)的患者通过动态血压诊断高血压,男性患者的诊断符合率高于女性患者,55.1%vs 24.2%,P<0.001。结论:诊室血压与动态血压高血压的诊断符合率不高,女性患者尤为明显。对OBP高值者建议监测ABP来确诊,或予以定期随访观查。
OBJECTIVE: To compare the coincidence rates of office blood pressure and ambulatory blood pressure in the diagnosis of hypertension. Methods: 151 patients with blood pressure ≥140 / 90mmHg in clinic were enrolled and their ambulatory blood pressure was monitored 24 hours later. The blood pressure parameters of each patient were calculated and statistically analyzed. Results: The systolic blood pressure, diastolic blood pressure and pulse pressure of the clinic were all higher than those of ambulatory blood pressure, daytime and nighttime mean systolic blood pressure, diastolic blood pressure and pulse pressure, P <0.01; and the office blood pressure was higher than 24h ambulatory blood pressure Average blood pressure. Hypertension was diagnosed by ambulatory blood pressure in 42.4% (64/151) of the patients with hypertension in clinic, and the diagnostic coincidence rate of male patients was higher than that of female patients (55.1% vs 24.2%, P <0.001). Conclusion: The coincidence rate of clinic blood pressure and ambulatory blood pressure and hypertension is not high, especially in female patients. For patients with high OBP, it is recommended to monitor ABP for diagnosis or to follow up regularly.
