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

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 1 – 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, p0.05, systolic and diastolic, respectively). CONCLUSION: This study showed that HBPM has a better correlation with LVMI than OBP.
