Comparison of office, home and 24-hour ambulatory blood pressures in borderline and mild hypertension.
Clinic/office (casual), home (self), and twenty-four-hour ambulatory (ABP) blood pressure determinations were compared in 32 subjects defined by conventional office criteria as mild or borderline hypertensives. Office diastolic blood pressures (mean 93.1 +/- 5.3 mmHg) were significantly higher than either home (mean 88.9 +/- 7.1 mm Hg) or awake ABP (mean 88.4 +/- 8.4 mm Hg) readings for the total group, as well as for the mild hypertension subgroup (office mean 96.0 +/- 3.5 mm Hg, home mean 91.0 +/- 8.0, awake ABP mean 90.4 +/- 8.8) but not for the borderline subgroup. In the total study group, office diastolic blood pressure (DBP) correlated better with home DBP (r = 0.58, p = 0.0005), than with the awake ABP (r = 0.40, p = 0.02). Home DBP correlated well with awake DBP (r = 0.48, p = 0.006). In subgroup analysis, office DBPs correlated well with home (self) readings for both the mild (r = 0.53, p = 0.03) and the borderline (r = 0.62, p = 0.01) subgroups. When office DBPs were compared with awake ABP DBPs, the correlation coefficient for the mild subgroup was significant (r = 0.49, p = 0.04); this was not the case for the borderline subgroup (r = 0.10, p = NS). Comparison of home (self) DBPs with awake ABP determinations revealed a good correlation for the borderline subgroup (r = 0.63, p = 0.01) but not for the mild subgroup (r = 0.35, p = NS).(ABSTRACT TRUNCATED AT 250 WORDS)
