Our previous study showed that post-clinic blood pressure (BP) taken 15 min after a physician-patient encounter was the lowest reading in a routine clinic. We aimed to validate this reading with 24 h Ambulatory Blood Pressure Monitoring (ABPM) readings. A cross-sectional study was conducted in the cardiology clinics at the Aga Khan University, Pakistan. Hypertensive patients aged ≥ 18 years, or those referred for the diagnosis of hypertension were included.
Of 150 participants, 49% were males. 76% of all participants were hypertensive. Pre-clinic BP reading was measured by a nurse, in-clinic by a physician and 15 min post-clinic by a research assistant using a validated, automated BP device (Omron-HEM7221-E). All patients were referred for 24 h ABPM. Among the three readings taken during a clinic visit, mean (± SD) systolic BP (SBP) pre-clinic, in-clinic, and 15 min post-clinic were 153.2 ± 23, 152.3 ± 21, and 140.0 ± 18 mmHg, respectively. Mean (± SD) diastolic BP (DBP) taken pre-clinic, in-clinic and 15 min post-clinic were 83.5 ± 12, 90.9 ± 12, and 86.4 ± 11 mmHg respectively. Mean (± SD) daytime ambulatory SBP, DBP and pulse readings were 134.7 ± 15, 78.7 ± 15 mmHg, and 72.6 ± 12/min, respectively. Pearson correlation coefficients of pre-clinic, in-clinic and post-clinic SBP with daytime ambulatory-SBP were 0.4 (p value: < 0.001), 0.5 (p value: < 0.001) and 0.6 (p value: < 0.001), respectively. Post-clinic BP has a good correlation with ambulatory BP and may be considered a more reliable reading in the clinic setting.
我们之前的研究表明，医患会面后15分钟测量的诊后血压是常规诊所中最低的读数。我们旨在通过24小时动态血压监测（ABPM）读数来验证这一读数。在巴基斯坦阿迦汗大学的心脏病诊所进行了一项横断面研究。纳入年龄≥18岁的高血压患者或被转诊以诊断高血压的患者。
150名参与者中，49%为男性。所有参与者中有76%患有高血压。诊前血压读数由护士测量，诊中由医生测量，诊后15分钟由研究助理使用经过验证的自动血压设备（欧姆龙HEM7221-E）测量。所有患者均被转诊进行24小时ABPM。在一次诊所就诊期间测量的三次读数中，诊前、诊中及诊后15分钟的平均（±标准差）收缩压（SBP）分别为153.2±23、152.3±21和140.0±18mmHg。诊前、诊中及诊后15分钟测量的平均（±标准差）舒张压（DBP）分别为83.5±12、90.9±12和86.4±11mmHg。白天动态SBP、DBP和脉搏读数的平均（±标准差）分别为134.7±15、78.7±15mmHg和72.6±12次/分钟。诊前、诊中及诊后SBP与白天动态SBP的Pearson相关系数分别为0.4（p值：<0.001）、0.5（p值：<0.001）和0.6（p值：<0.001）。诊后血压与动态血压具有良好的相关性，在临床环境中可被视为更可靠的读数。
