The prevalence of inter-arm BP difference is high in hypertension and is associated with adverse cardiovascular outcomes. We performed a retrospective chart review of prevalent patients in the Ottawa Hospital Hypertension Center to assess for prevalence, risk factors, and whether finding of inter-arm BP difference >10 mmHg leads to investigations of the aorta and aortic arch. Inter-arm BP difference among 493 patients was present in 16.2% (95% confidence interval [CI]13.3-19.9%), and it was associated with presence of peripheral arterial disease. Physicians did not investigate ascending aorta and aortic arch for causes of the clinically significant inter-arm BP difference.
双臂血压差值在高血压中很常见，与不良心血管结局相关。我们对渥太华医院高血压中心的现患患者进行了回顾性图表审查，以评估其患病率、危险因素，以及臂间血压差值>10mmHg 是否会导致对主动脉和主动脉弓的检查。493 名患者中有 16.2%（95%置信区间 [CI]13.3-19.9%）存在臂间血压差值，且与外周动脉疾病的存在相关。医生并未对导致臂间血压差值有临床意义的升主动脉和主动脉弓进行检查。
