Home blood pressure measurement and ambulatory blood pressure measurement versus office blood pressure measurement

Abstract

Purpose - To compare both home blood pressure measurement (HBPM) and ambulatory blood pressure monitoring (ABPM) with office blood pressure measurement (OBP); and also to compare the correlation between HBPM and OBP with LVMI (left ventricular mass index). Methods - Protocol 1 - 68 hypertensive patients (58±12 years, 37 females): a) self recorded blood pressure at home in the 7 days; b) recorded the ABPM during 24 hours; and c) the physician recorded blood pressure in the office. Protocol 2-41 hypertensive patients underwent the HBPM, OBP, and BI-dimensional echocardiogram. Results - Protocol I - OBP (153±24/96±13mmHg) was higher (p<0.05) than HBPM (133±18/84±12mmHg) and ABPM (137±17/87±12mmHg); Protocol 2 - LVMI correlated better with HBPM (r = 0.39 / 0.49. p<0.05, systolic and diastolic, respectively) than OBP (r = 0.02/ 0.22, p>0.05, systolic and diastolic, respectively). Conclusion - This study showed that HBPM has a better correlation with LVMI than OBP.
