We aimed to determine the characteristics of home blood pressure (BP) in very elderly hypertensives. A total of 485 treated hypertensive patients ≥18 years (median age, 70.8 [interquartile range, 18]; 67.2% women) underwent home BP measurements. Characteristics of patients ≥80 and <80 years of age and prevalence of office and home uncontrolled hypertension, isolated morning (IMH), isolated evening, isolated office, and masked hypertension were compared. Very elderly subjects had higher levels of systolic and lower levels of diastolic BP at home, a higher prevalence of home uncontrolled hypertension (68.5% vs. 37.7%; P < .001), masked hypertension (30.6% vs. 14.9%; P = .02), and IMH (19.4% vs. 10.9%; P = .02), and a lower prevalence of isolated office hypertension (8.3% vs. 18.8%; P = .01). When using differential home BP thresholds in the very elderly, determined through the percentile method, statistical differences disappeared, except for IMH. The very elderly depict a particular home BP profile. Benefit from using differential home BP thresholds should be determined in prospective studies.
