To describe patient hypertension knowledge and associations with blood pressure measurements.
Patients with chronic kidney disease (CKD) were asked about the impact of high blood pressure on kidneys and their target blood pressure goal. Systolic blood pressure was measured using automated sphygmomanometers.
In 338 adults with hypertension and pre-dialysis CKD, the median [IQR] age was 59 [47,68] years, 45% [n = 152] were women, and 18% [n = 62] were non-white. Lower systolic blood pressure (SBP) was associated with female sex (SBP mmHg median [IQR] 132 [117,149] women vs. 137 [124,152] men; p = 0.04), less advanced CKD (SBP 134 [122,147] stages 1-2 vs. 132 [118,148] stage 3 vs. 140 [125,156] stages 4-5; p = 0.01), and patient ability to correctly identify SBP goal (SBP 134 [119,150] correct vs. 141 [125,154] incorrect; p = 0.05). In adjusted analysis, knowledge of blood pressure goal remained independently associated with lower SBP (-9.96 mmHg [-19.97, -1.95] in correct respondents vs. incorrect; p<0.001).
Patient knowledge of goal blood pressure is independently associated with improved blood pressure control.
Interventions to improve patient knowledge of specific blood pressure targets may have an important role in optimizing blood pressure management.
描述患者的高血压知识及其与血压测量值的关系。
询问患有慢性肾脏病（CKD）的患者高血压对肾脏的影响及其目标血压目标值。使用自动血压计测量收缩压。
在 338 名患有高血压和透析前 CKD 的成年人中，中位数[IQR]年龄为 59 [47,68]岁，45%[n = 152]为女性，18%[n = 62]为非白人。较低的收缩压（SBP）与女性性别相关（SBP mmHg 中位数[IQR] 132 [117,149] 女性 vs. 137 [124,152] 男性；p = 0.04），CKD 进展程度较低（SBP 134 [122,147] 1-2 期 vs. 132 [118,148] 3 期 vs. 140 [125,156] 4-5 期；p = 0.01），以及患者正确识别 SBP 目标的能力（SBP 134 [119,150] 正确 vs. 141 [125,154] 错误；p = 0.05）。在调整分析中，血压目标知识仍然与较低的 SBP 独立相关（正确应答者比错误应答者低 9.96 mmHg [-19.97，-1.95]；p<0.001）。
患者对目标血压的知识与血压控制的改善独立相关。
改善患者对特定血压目标的知识的干预措施可能在优化血压管理方面发挥重要作用。
