Simultaneous noninvasive blood pressure measurement were recorded bilaterally in 40 young and 40 elderly subjects. Overall interarm blood pressure (BP) differences for the elderly and young groups were similar, the absolute interarm differences being for systolic blood pressure (SBP) elderly: 4.2 mmHg (95% CI 3.1-5.3 mmHg); young 3.3 mmHg(2.6-4.1 mmHg); diastolic blood pressure (DBP) elderly 3.6 mmHg(2.8-4.4 mmHg), young 2.7 mmHg(2.0-3.3 mmHg). However, the range of interarm BP differences was wide. Four (10%) of the elderly had an interarm SBP difference > 10 mmHg compared to one (3%) of the young group. Interarm DBP differences > 8 mmHg were found in three (8%) of the elderly and in none of the young group. Although age does not affect mean interarm BP differences, clinically important interarm BP differences exist in both young and elderly subjects. Blood pressure should be measured in both arms of all patients at initial assessment to avoid potential problems with misclassification of blood pressure status.
对40名年轻受试者和40名老年受试者双侧同时进行无创血压测量。老年组和年轻组的双臂血压总体差异相似，收缩压的双臂绝对差异为：老年组4.2 mmHg（95%可信区间3.1 - 5.3 mmHg）；年轻组3.3 mmHg（2.6 - 4.1 mmHg）；舒张压的双臂绝对差异为：老年组3.6 mmHg（2.8 - 4.4 mmHg），年轻组2.7 mmHg（2.0 - 3.3 mmHg）。然而，双臂血压差异范围较宽。4名（10%）老年受试者的双臂收缩压差异>10 mmHg，而年轻组为1名（3%）。3名（8%）老年受试者的双臂舒张压差异>8 mmHg，年轻组无此情况。虽然年龄不影响双臂血压的平均差异，但年轻和老年受试者中均存在具有临床意义的双臂血压差异。在初次评估时，应对所有患者的双臂进行血压测量，以避免血压状态错误分类的潜在问题。
