The effect of sex on the correlation between oscillometric and central aortic blood pressures (BP) is largely unknown. BP was simultaneously measured in the brachial artery using an oscillometric device and in the aorta using a fluid-filled catheter in 98 patients undergoing coronary angiography. Mean age (± standard deviation) was 58 ± 12 years, with 55% of the patients being male. Mean BP (MBP) measured by the oscillometric device and in the aorta were similar when the group was examined as a whole, but the oscillometric device overestimated MBP in men and underestimated MBP in women. Oscillometric pressures accurately estimated diastolic BP in women but overestimated diastolic BP in men and underestimated systolic BP in both sexes. The oscillometric device underestimated aortic pulse pressure in both sexes but less in men than in women. The accuracy of oscillometric MBP and diastolic BP varied as a function of aortic MBP, but sex-related differences in the accuracy of oscillometric pressures remained significant after adjusting for MBP, body mass index, height, age, race, heart rate, diabetes, smoking status, and BP-lowering therapies using a multivariate logistic regression model. Sex is an important determinant of the accuracy of oscillometric BP.
性别对示波法与中心主动脉血压（BP）之间相关性的影响在很大程度上尚不清楚。在 98 例行冠状动脉造影的患者中，同时使用示波法设备在肱动脉和充满液体的导管在主动脉测量血压。平均年龄（±标准差）为 58 ± 12 岁，其中 55%的患者为男性。当整个组进行检查时，示波法设备测量的平均血压（MBP）和主动脉中的 MBP 相似，但示波法设备高估了男性的 MBP，低估了女性的 MBP。示波法压力在女性中准确估计舒张压，但高估男性的舒张压，并低估男女的收缩压。示波法设备低估了男女的主动脉脉搏压，但男性比女性小。示波法 MBP 和舒张压的准确性随主动脉 MBP 而变化，但在校正 MBP、体重指数、身高、年龄、种族、心率、糖尿病、吸烟状况和使用多元逻辑回归模型的降压治疗后，示波法压力的性别相关差异仍然显著。性别是示波法 BP 准确性的重要决定因素。
