SPRINT (Systolic Blood Pressure Intervention Trial) demonstrated the benefit of achieving strict blood pressure control with a lower target blood pressure level in high-risk patients with hypertension. The aim of this post hoc analysis was to investigate the relationship between the 2-year average on-treatment home blood pressure and cardiovascular disease risk in subgroups stratified by risk status using data from the HONEST study (Home Blood Pressure Measurement With Olmesartan Naive Patients to Establish Standard Target Blood Pressure). Participants in the HONEST study (n=21 591) were stratified according to risk level as follows: SPRINT population (n=5823)-patients (≥50 years of age) without diabetes mellitus or prior stroke, with SPRINT-defined cardiovascular risk and systolic blood pressure (SBP) of ≥130 mm Hg; SPRINT-excluded high-risk population (n=5481)-patients with diabetes mellitus or prior stroke; and non-SPRINT low-risk population-all other patients in the HONEST study (n=10 287).

The appropriate target blood pressure (BP) in elderly patients with hypertension remains uncertain. We investigated the relationship between morning home systolic blood pressure (MHSBP) during follow-up and cardiovascular (CV) risk in outpatients receiving olmesartan-based treatment aged <75 years (n = 16799) and ≥75 years (n = 4792) in the HONEST study. In the follow-up period (mean 2.

In patients with insufficient blood pressure (BP) control, despite using a combination regimen containing an angiotensin receptor blocker and a calcium channel blocker (CCB), whether a greater dose of CCB or adding a diuretic is more effective at lowering BP remains unclear. We conducted a multicenter randomized clinical trial to compare the efficacy of switching from the daily administration of a single-pill fixed-dose combination of irbesartan (100 mg) and amlodipine (5 mg) to irbesartan (100 mg) with an increased dose of amlodipine (10 mg) (HD group, n=62) or irbesartan (100 mg) and amlodipine (5 mg) with 1 mg of indapamide (D group, n=63) in patients with poorly controlled hypertension. BP measured at home was monitored by a physician using a telemonitoring system.

The prognostic implications of treated white coat hypertension (WCH) and masked hypertension (MH) in patients with diabetes mellitus (DM) or chronic kidney disease (CKD) are not well documented. Using data from the HONEST study (n=21 591), we investigated the relationships between morning home systolic blood pressure (MHSBP) or clinic systolic blood pressure (CSBP) and cardiovascular (CV) risk in hypertensive patients with and without DM or CKD receiving olmesartan-based antihypertensive therapy. The study included 4426 DM patients and 4346 CKD patients at baseline who had 101 and 87 major CV events, respectively, during the follow-up.

Objective: A direct renin inhibitor, aliskiren, has a longer stable antihypertensive effect compared with other renin-angiotensin-aldosterone system (RAAS) inhibitors.

Methods: This study was a 6-month, single-center, open trial conducted between December 2010 and November 2011 to assess the antihypertensive effect of adding aliskiren (300 mg) to the treatment of essential hypertension patients whose target blood pressure (BP) had not been achieved and to assess whether it was possible to reduce the amount of antihypertensive drugs used.

Results: The results showed an overall improvement in the target BP achievement rate of 60% for clinic BP and 52% for home BP measurements (75 cases total).

Using data from the large-scale HONEST (Home blood pressure measurement with Olmesartan Naive patients to Establish Standard Target blood pressure) study, we investigated the characteristics of the effects of olmesartan-based treatment on morning hypertension in Asian hypertensive patients. Specifically, we investigated the relationship between baseline blood pressure (BP) and BP reduction after 16 weeks by linear regression analyses; determinants of BP reduction were also investigated. For both morning home BP (MHBP) and clinic BP (CBP), reduced systolic BP (SBP) after 16 weeks was associated with baseline SBP (P<0.

When interpreting home blood pressure (BP) measurements in hypertensive patients, differences between clinic and home BP should be noted. To investigate the differences between clinic and morning home BP in hypertensive patients, we analyzed clinic systolic BP (CSBP) and morning home systolic BP (MHSBP) data from the large-scale observational HONEST (Home BP measurement with Olmesartan Naive patients to Establish Standard Target blood pressure) study (n=21 340), using BP measurements obtained before starting olmesartan administration. We generated Bland-Altman plots, with the horizontal axis representing mean CSBP and MHSBP ([CSBP+MHSBP]/2) and the vertical axis representing the difference between CSBP and MHSBP (CSBP-MHSBP).

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.

To investigate the blood pressure (BP)-lowering effect of olmesartan in relation to chronic kidney disease (CKD)-associated sympathetic nerve activity, a subanalysis was performed using data from the first 16 weeks of the Home BP Measurement With Olmesartan-Naive Patients to Establish Standard Target Blood Pressure (HONEST) study, a prospective observational study of hypertensive patients. Essential hypertensive patients who took no antihypertensive agent at baseline were classified based on baseline morning home systolic BP (MHSBP) in quartiles. In each class, patients were further classified based on baseline morning home pulse rate (MHPR).

Objective: Brachial-ankle pulse wave velocity (baPWV) is a measure of arterial stiffness. However, precisely how aging, hypertension and other factors influence this in progressively stiffening large arteries, especially in older adults, remains uncertain. We examined changes in arterial stiffness in a population of active older Japanese adults using a five-year follow-up cohort study.

On the basis of the studies that investigated the relationship between baseline clinic blood pressure (CBP) or home blood pressure (HBP) values and cardiovascular (CV) events, HBP has been reported to have a stronger prognostic ability. However, few studies have compared the prognostic ability of on-treatment CBP and HBP. The relationship between on-treatment HBP, measured twice in the morning and twice at bedtime, and CV events was investigated in over 20 000 patients in the HONEST (Home blood pressure measurement with Olmesartan Naive patients to Establish Standard Target blood pressure) Study, a prospective, 2-year observational study of treatment with an angiotensin receptor blocker, olmesartan (OLM), in OLM-naive hypertensive patients.

Article Synopsis
  • Strict blood pressure control is crucial for managing hypertension, yet less than 50% of patients reach their target levels according to various studies.
  • Reasons for this poor control include non-compliance with medication, lifestyle factors like obesity and high salt intake, sleep apnea, and interactions with other medications.
  • To improve blood pressure management, it’s essential to identify these obstacles and implement comprehensive strategies led by healthcare professionals.
