Increased visit-to-visit variability (VVV) of blood pressure, which is calculated based on several readings, has been suggested to be a significant predictor of cardiovascular events and mortality, independent of mean blood pressure. This study examined associations between the VVV of systolic blood pressure (SBP) measured annually and cardiovascular disease (CVD) events among 72,617 Japanese subjects. Data were obtained from the Japan Epidemiology Collaboration on Occupational Health Study, which is an ongoing epidemiological survey of workers in Japan. VVV was calculated as the coefficient of variation of SBP readings from 2008 to 2011; information on fatal and nonfatal CVD events was collected from registries of specific outcomes between April 2012 and March 2019. A Cox proportional hazards model was applied to investigate associations after adjusting for mean SBP between 2008 and 2011 and covariates. During the 7-year follow-up period, there were 63 CVD fatalities and 314 CVD events (combining fatal and nonfatal events). The results showed that a one-standard deviation increase in VVV was associated with a significant increase in the risk of CVD mortality (hazard ratio [HR] = 1.42; 95% confidence interval [CI] = 1.32–1.54); those in the highest tertile had a 3.20 times (95% CI = 1.26–8.17) higher risk of CVD mortality than those in the lowest tertile. We found less pronounced associations regarding CVD events (HR = 1.08, 95% CI = 1.02–1.15). In conclusion, VVV was significantly associated with CVD mortality in our Japanese working population.

日本劳动年龄人口血压和心血管事件的访问间变异性:日本流行病学合作职业健康研究的结果

血压的增加的就诊间变异性 (VVV) 是基于几个读数计算的,已被认为是心血管事件和死亡率的重要预测指标,与平均血压无关。本研究调查了 72,617 名日本受试者每年测量的收缩压 (SBP) 的 VVV 与心血管疾病 (CVD) 事件之间的关联。数据来自日本职业健康流行病学合作研究,这是一项对日本工人进行的流行病学调查。VVV 计算为 2008 年至 2011 年 SBP 读数的变异系数;从 2012 年 4 月至 2019 年 3 月期间的特定结果登记处收集了有关致命和非致命 CVD 事件的信息。在调整 2008 年至 2011 年的平均 SBP 和协变量后,应用 Cox 比例风险模型来调查关联。在 7 年的随访期间,有 63 例 CVD 死亡和 314 例 CVD 事件(包括致命和非致命事件)。结果表明,VVV 增加一个标准差与 CVD 死亡风险显着增加相关(风险比 [HR] = 1.42;95% 置信区间 [CI] = 1.32–1.54);最高三分位数人群的心血管疾病死亡风险是最低三分位数人群的 3.20 倍(95% CI = 1.26-8.17)。我们发现关于 CVD 事件的关联不太明显(HR = 1.08, 95% CI = 1.02–1.15)。总之,VVV 与我们日本工作人群的 CVD 死亡率显着相关。在 7 年的随访期间,有 63 例 CVD 死亡和 314 例 CVD 事件(包括致命和非致命事件)。结果表明,VVV 增加一个标准差与 CVD 死亡风险显着增加相关(风险比 [HR] = 1.42;95% 置信区间 [CI] = 1.32–1.54);最高三分位数人群的心血管疾病死亡风险是最低三分位数人群的 3.20 倍(95% CI = 1.26-8.17)。我们发现关于 CVD 事件的关联不太明显(HR = 1.08, 95% CI = 1.02–1.15)。总之,VVV 与我们日本工作人群的 CVD 死亡率显着相关。在 7 年的随访期间,有 63 例 CVD 死亡和 314 例 CVD 事件(包括致命和非致命事件)。结果表明,VVV 增加一个标准差与 CVD 死亡风险显着增加相关(风险比 [HR] = 1.42;95% 置信区间 [CI] = 1.32–1.54);最高三分位数人群的心血管疾病死亡风险是最低三分位数人群的 3.20 倍(95% CI = 1.26-8.17)。我们发现关于 CVD 事件的关联不太明显(HR = 1.08, 95% CI = 1.02–1.15)。总之,VVV 与我们日本工作人群的 CVD 死亡率显着相关。结果表明,VVV 增加一个标准差与 CVD 死亡风险显着增加相关(风险比 [HR] = 1.42;95% 置信区间 [CI] = 1.32–1.54);最高三分位数人群的心血管疾病死亡风险是最低三分位数人群的 3.20 倍(95% CI = 1.26-8.17)。我们发现关于 CVD 事件的关联不太明显(HR = 1.08, 95% CI = 1.02–1.15)。总之,VVV 与我们日本工作人群的 CVD 死亡率显着相关。结果表明,VVV 增加一个标准差与 CVD 死亡风险显着增加相关(风险比 [HR] = 1.42;95% 置信区间 [CI] = 1.32–1.54);最高三分位数人群的心血管疾病死亡风险是最低三分位数人群的 3.20 倍(95% CI = 1.26-8.17)。我们发现关于 CVD 事件的关联不太明显(HR = 1.08, 95% CI = 1.02–1.15)。总之,VVV 与我们日本工作人群的 CVD 死亡率显着相关。95% CI = 1.02–1.15)。总之,VVV 与我们日本工作人群的 CVD 死亡率显着相关。95% CI = 1.02–1.15)。总之,VVV 与我们日本工作人群的 CVD 死亡率显着相关。
