BACKGROUND
Blood pressure variability (BPV) and arterial stiffness show an association with increased cardiovascular events. Evidences demonstrated an association between higher short-term systolic BPV and stiffer arteries. There is no previous study assessed the correlation between BPV and arterial stiffness measured by a Mobil-O-Graph device. We issued to evaluate the correlation between short-term BPV parameters and Mobil-O-Graph pulse wave velocity (PWV) among suspected hypertensive individuals under treatment.
METHODS
Mobil-O-Graph device estimated arterial stiffness (oscillometric PWV [oPWV]) in 649 individuals, and they recorded 24-h ambulatory BP; 428 had suspected hypertension and 221 under treatment. We analyzed the correlation between oPWV and measures of BPV: SD of 24 h BP (24-h SD), SD of daytime BP (daytime-SD), and SD of nighttime BP (nighttime-SD), weighted SD of 24-h BP (wSD), coefficient of variation of 24-h BP (CV 24-h) and average real variability (ARV).
RESULTS
Oscillometric PWV showed a positive correlation with all systolic BPV measures, in both groups. Among suspected hypertensives: 24-h SD, r = 0.30; SD daytime-SD, r = 0.34; nighttime-SD, r = 0.16; wSD, r = 0.30; CV 24-h, r = 0.24; ARV, r = 0.22. In the treated individuals: 24-h SD, r = 0.46; daytime-SD, r = 0.47; nighttime-SD, r = 0.35; wSD, r = 0.50; CV 24-h, r = 0.43; ARV, r = 0.37, all P < 0.001. Diastolic BPV demonstrated association with some measures of BPV. In suspected hypertensive group: nighttime-SD, r = 0.13; wSD, r = 0.10, both P < 0.001. And in treated individuals: daytime-SD, r = 0.23; wSD, r = 0.22; CV 24-h, r = 0.19 (all P < 0.001), ARV, r = 0.15 (P < 0.05). Systolic daytime-SD in suspected and diastolic CV 24-h in treated group independently predicted oPWV.
CONCLUSION
We observed a positive and independent correlation between Mobil-O-Graph pulse wave velocity and BPV measures, strong to systolic BPV and weak to diastolic BP.
背景
血压变异性（BPV）与动脉僵硬度和心血管事件增加有关。有证据表明，较高的短期收缩压变异性与动脉僵硬有关。此前尚无研究评估BPV与通过Mobil-O-Graph设备测量的动脉僵硬度之间的相关性。我们旨在评估接受治疗的疑似高血压个体的短期BPV参数与Mobil-O-Graph脉搏波速度（PWV）之间的相关性。
方法
Mobil-O-Graph设备对649名个体的动脉僵硬度（示波PWV [oPWV]）进行了评估，并记录了他们的24小时动态血压；其中428人疑似患有高血压，221人正在接受治疗。我们分析了oPWV与BPV测量指标之间的相关性：24小时血压标准差（24小时SD）、日间血压标准差（日间-SD）、夜间血压标准差（夜间-SD）、24小时血压加权标准差（wSD）、24小时血压变异系数（CV 24小时）和平均实际变异性（ARV）。
结果
在两组中，示波PWV与所有收缩压BPV测量指标均呈正相关。在疑似高血压患者中：24小时SD，r = 0.30；日间-SD，r = 0.34；夜间-SD，r = 0.16；wSD，r = 0.30；CV 24小时，r = 0.24；ARV，r = 0.22。在接受治疗的个体中：24小时SD，r = 0.46；日间-SD，r = 0.47；夜间-SD，r = 0.35；wSD，r = 0.50；CV 24小时，r = 0.43；ARV，r = 0.37，所有P < 0.001。舒张压BPV与某些BPV测量指标有关。在疑似高血压组中：夜间-SD，r = 0.13；wSD，r = 0.10，两者P < 0.001。在接受治疗的个体中：日间-SD，r = 0.23；wSD，r = 0.22；CV 24小时，r = 0.19（所有P < 0.001），ARV，r = 0.15（P < 0.05）。疑似患者的收缩期日间-SD和治疗组的舒张期CV 24小时独立预测oPWV。
结论
我们观察到Mobil-O-Graph脉搏波速度与BPV测量指标之间存在正相关且独立，与收缩压BPV相关性强，与舒张压相关性弱。
