To establish the validity and clinical value of home blood pressure measurements (HBPM) in the treatment follow-up of patients with essential hypertension to rule out or to confirm poor control of blood pressure obtained in the doctor's office with a mercury sphygmomanometer.
Observational, cross-sectional study was carried out to validate HBPM in treated hypertensive patients poorly controlled by office-based casual blood pressure measurements. Measurements were made on 2 consecutive days with six readings taken per day. To do this, 2 x 2 tables were drawn up to validate the HBPM using ABPM as the reference method. Sensitivity (S), specificity (Sp), positive probability quotient (+PQ) and negative probability quotient (-PQ) were calculated. The study population (n = 149) was selected by consecutive sampling of the hypertensive patients seen in the Vallada Health Centre. Only 124 patients could be evaluated.
Values obtained with HBPM were: S 97.3% (95% CI 90.4-99.7%), Sp 62.7% (48.1-75.9%), +PQ 2.61 (1.82-3.73) and -PQ 0.04 (0.01-0.71).
Home monitoring of blood pressure is a useful alternative to ABPM to rule out office-based poor control of hypertensive patients, but not to confirm it.
确定家庭血压测量（HBPM）在原发性高血压患者治疗随访中的有效性和临床价值，以排除或确认使用汞柱式血压计在诊室测得的血压控制不佳情况。
开展观察性横断面研究，以验证在诊室偶测血压控制不佳的高血压患者中HBPM的情况。连续两天进行测量，每天测量6次。为此，以动态血压监测（ABPM）作为参考方法，绘制2×2表格来验证HBPM。计算敏感性（S）、特异性（Sp）、阳性概率商（+PQ）和阴性概率商（-PQ）。通过对在瓦拉达健康中心就诊的高血压患者进行连续抽样，选取研究人群（n = 149）。仅124例患者可进行评估。
HBPM获得的值为：S 97.3%（95%可信区间90.4 - 99.7%），Sp 62.7%（48.1 - 75.9%），+PQ 2.61（1.82 - 3.73），-PQ 0.04（0.01 - 0.71）。
家庭血压监测是ABPM的一种有用替代方法，可用于排除高血压患者诊室血压控制不佳的情况，但不能用于确认。
