Effectiveness of olmesartan-based treatment on home and clinic blood pressure in elderly patients with masked and white coat hypertension.

Abstract

Few large-scale studies have evaluated the effectiveness of angiotensin receptor blockers in patients with masked hypertension (MH) and white coat hypertension (WCH) based on age using real-world blood pressure (BP) data. We used data from the Home BP measurement with Olmesartan Naive patients to Establish Standard Target BP (HONEST) study to investigate the effectiveness of olmesartan-based treatment by patient age (<65 years of age, n = 9817; 65-74 years of age, n = 6792; ⩾ 75 years of age, n = 4732), focusing on morning home BP (strongly associated with cardiovascular disease and useful for MH and WCH diagnosis). Sixteen weeks of treatment changed morning home BP (mean systolic/diastolic) by -18.1/-9.7, -15.9/-7.4 and -14.2/-6.4 mm Hg and clinic BP by -20.1/-11.3, -17.3/-8.7 and -15.4/-7.2 mm Hg, in these age groups, respectively (P < 0.0001). Pulse pressure decreased (-7.8 to -8.8 mm Hg, P < 0.0001). Patients aged ⩾ 80 years experienced similar BP and pulse pressure changes. In patients aged ⩾ 75 years, mean morning and clinic BP after 16 weeks was 137.5/74.8 and 129.7/70.4 mm Hg, respectively, in MH patients and 132.3/72.2 and 139.7/72.7 mm Hg, respectively, in WCH patients. Regardless of age, only elevated clinic or home BP values decreased to target ranges. The incidence of adverse effects associated with excessive BP lowering was low in all of the age groups. In conclusion, our study suggests that olmesartan-based treatment was safe and useful for managing MH, WCH and sustained hypertension in elderly patients. The lack of a placebo group was a limitation of the study.
