本研究旨在评估50例正常工作的高血压患者（平均年龄60.5±8.9岁，92.0%为男性，96%为高血压患者）用一种新型腕带式可穿戴血压监测装置测量的血压（BP）与心脏磁共振成像（cmi - lvmi）测量的左心室质量指数之间的关系。参与者被要求根据指南推荐的标准化家庭血压测量方法，在早上和晚上两次自我测量可穿戴式血压，并在五个预定时间和任何额外的时间点在不活动的情况下，每次测量一次，最长7天。总共收集了2105个可穿戴血压测量值（家庭血压：747[早上：409，晚上：338]，流动状态：1358[工作场所：942]），超过5.5 +/- 1.2天。所有可穿戴收缩压（SBP）读数平均值（129.8 +/- 11.0 mmHg）与cmi - lvmi呈弱相关（r = 0.265, p = 0.063）。晨间家庭可穿戴收缩压平均值（128.5 +/- 13.8 mmHg）与cmi - lvmi显著相关（r = 0.378, p = 0.013），而动态可穿戴收缩压平均值（132.5 +/- 12.7 mmHg）与cmi - lvmi无显著相关（r = 0.215, p = 0.135）。所有可穿戴式sbp （153.3 +/- 13.9 mmHg）和日间可穿戴式sbp （152.9 +/- 13.9 mmHg）的最高3个值的平均值比早晨家庭可穿戴式sbp （137.0 +/- 15.9 mmHg）高16 mmHg。这些峰值与cmi - lvmi显著相关（r = 0.320, p = 0.023; r = 0.310, p = 0.029; r = 0.451, p = 0.002）。总之，增加可穿戴血压测量的数量，可以检测个人血压峰值，可能会增加这些测量的临床价值，作为指南推荐的家庭血压测量的补充，但需要进一步的研究来证实这些发现。
This study sought to evaluate the relationship between blood pressure (BP) taken by a new wrist-cuff oscillometric wearable BP monitoring device and left ventricular mass index measured by cardiac magnetic resonance imaging (cMRI-LVMI) in 50 hypertensive patients (mean age 60.5 +/- 8.9 years, 92.0% men, 96% treated for hypertension) with regular employment. Participants were asked to self-measure their wearable BPs twice in the morning and evening under a guideline-recommended standardized home BP measurement, and once each at five predetermined times and any additional time points under an ambulatory condition for a maximum of 7 days. In total, 2105 wearable BP measurements (home BP: 747 [morning: 409, evening: 338], ambulatory condition: 1358 [worksite: 942]) were collected over 5.5 +/- 1.2 days. The average of all wearable systolic BP (SBP) readings (129.8 +/- 11.0 mmHg) was weakly correlated with cMRI-LVMI (r = 0.265, p = 0.063). Morning home wearable SBP average (128.5 +/- 13.8 mmHg) was significantly correlated with cMRI-LVMI (r = 0.378, p = 0.013), but ambulatory wearable SBP average (132.5 +/- 12.7 mmHg) was not (r = 0.215, p = 0.135). The averages of the highest three values of all wearable SBPs (153.3 +/- 13.9 mmHg) and ambulatory wearable SBPs (152.9 +/- 13.9 mmHg) were 16 mmHg higher than that of the morning home wearable SBPs (137.0 +/- 15.9 mmHg). Those peak values were significantly correlated with cMRI-LVMI (r = 0.320, p = 0.023; r = 0.310, p = 0.029; r = 0.451, p = 0.002, respectively). In conclusion, an increased number of wearable BP measurements, which could detect individual peak BP, might add to the clinical value of these measurements as a complement to the guideline-recommended home BP measurements, but further studies are needed to confirm these findings.
