Little is known about patient awareness of nationally recommended blood pressure targets, especially among patients with cardiac disease. To examine this issue, we interviewed 738 patients hospitalized with coronary artery disease to assess their knowledge of their systolic and diastolic blood pressure levels as well as corresponding national targets. We used bivariate and multivariate analyses to determine if any patient demographic or clinical characteristics were associated with blood pressure knowledge. Only 66.1% of patients could recall their own systolic and diastolic blood pressure levels. Only 48.9% of all patients could correctly name targets for these values. Knowledge of target blood pressure levels was particularly poor among patients who were female (odds ratio (OR) 0.69; 95% confidence interval (CI) 0.49-0.98), aged > or =60 years (OR 0.70, CI 0.51-0.97), without any college education (OR 0.48, CI 0.35-0.65), without a documented history of hypertension (OR 0.57, CI 0.39-0.84), and with known diabetes (OR 0.46, CI 0.33-0.66). Patients in the highest risk group, according to Joint National Committee guidelines stratification, were no more knowledgeable about their blood pressure levels and targets than lower risk patients. A significant proportion of patients hospitalized with coronary artery disease do not know their own blood pressure levels or targets. Current blood pressure education efforts appear inadequate, particularly for certain patient subgroups in which hypertension is an important modifiable risk factor.
关于患者对国家推荐的血压目标的知晓情况，人们了解甚少，尤其是在患有心脏病的患者中。为了研究这个问题，我们采访了738名因冠状动脉疾病住院的患者，以评估他们对自己收缩压和舒张压水平以及相应国家目标的了解情况。我们使用双变量和多变量分析来确定是否有任何患者人口统计学或临床特征与血压知识相关。只有66.1%的患者能够回忆起自己的收缩压和舒张压水平。在所有患者中，只有48.9%能够正确说出这些数值的目标。在女性患者（优势比（OR）0.69；95%置信区间（CI）0.49 - 0.98）、年龄≥60岁的患者（OR 0.70，CI 0.51 - 0.97）、没有接受过任何大学教育的患者（OR 0.48，CI 0.35 - 0.65）、没有高血压病史记录的患者（OR 0.57，CI 0.39 - 0.84）以及患有糖尿病的患者（OR 0.46，CI 0.33 - 0.66）中，对目标血压水平的知晓情况尤其差。根据美国国家联合委员会指南分层，处于最高风险组的患者对自己的血压水平和目标的了解并不比低风险患者更多。相当一部分因冠状动脉疾病住院的患者不知道自己的血压水平或目标。目前的血压教育工作似乎并不充分，特别是对于某些高血压是重要可改变风险因素的患者亚组。
