Intensive or standard blood pressure control in patients with a history of ischemic stroke: RESPECT post hoc analysis.

The Recurrent Stroke Prevention Clinical Outcome (RESPECT) Study and its pooled analysis showed that intensive blood pressure (BP) lowering reduced recurrent stroke risk by 22% in patients with a history of stroke. Here, we report the effect of intensive BP lowering on the risk of recurrent stroke subtypes in patients with a history of ischemic stroke. RESPECT was a randomized clinical trial among 1280 people with a history of cerebral infarction or intracerebral hemorrhage.

Effects of an Antihypertensive Combination in Japanese Hypertensive Outpatients Based on the Long-acting Calcium Channel Blocker Benidipine on Vascular and Renal Events: A Sub-analysis of the COPE Trial.

Background: In the trial known as COPE (Combination Therapy of Hypertension to Prevent Cardiovascular Events), three benidipine (a Calcium Channel Blocker; CCB) regimens were compared. Hypertensive Japanese outpatients aged 40-85 years (n=3,293) who did not achieve the target blood pressure of <140/90 mmHg with benidipine 4 mg/day were treated with the diuretic thiazide (n=1,094) or a β-blocker (n=1,089) or an additional Angiotensin Receptor Blocker (ARB; n=1,110). A significantly higher incidence of hard cardiovascular composite endpoints and of fatal or non-fatal strokes was observed in the benidipine-β-blocker group compared to the benidipine-thiazide group.

Effect of Standard vs Intensive Blood Pressure Control on the Risk of Recurrent Stroke: A Randomized Clinical Trial and Meta-analysis.

Importance: The Systolic Blood Pressure Intervention Trial (SPRINT) demonstrated that a systolic blood pressure (BP) target less than 120 mm Hg was superior to less than 140 mm Hg for preventing vascular events. This trial excluded patients with prior stroke; therefore, the ideal BP target for secondary stroke prevention remains unknown.

Objective: To assess whether intensive BP control would achieve fewer recurrent strokes vs standard BP control.

Features of and preventive measures against hypertension in the young.

The Japanese hypertension guidelines report that essential hypertension is detected in 1-3% of upper elementary and high school students during blood pressure (BP) screenings. Hypertension in these age groups is an emerging public health concern mainly attributed to the rising rate of pediatric obesity. Considering the existence of BP tracking phenomenon, early preventive education and instruction are necessary, especially for male students with moderately elevated BP showing a tendency toward obesity, despite the low prevalence of hypertension in high school students.

Effects of Calcium-Channel Blocker Benidipine-Based Combination Therapy on Cardiac Events - Subanalysis of the COPE Trial.

Background: The Combination Therapy of Hypertension to Prevent Cardiovascular Events (COPE) trial was conducted to compare the effects of regimens combining the dihydropyridine calcium-channel blocker benidipine with each of 3 secondary agent types (an angiotensin-receptor blocker (ARB), a β-blocker and a thiazide) in Japanese hypertensive outpatients who did not achieve target blood pressure (<140/90 mmHg) with benidipine 4 mg/day alone. The analysis included 3,293 patients (ARB, 1,110; β-blocker, 1,089; thiazide, 1,094) with a median follow-up of 3.61 years.

On-Treatment Blood Pressure and Cardiovascular Outcomes in Older Adults With Isolated Systolic Hypertension.

Unlabelled: Our aim was to assess optimal on-treatment blood pressure (BP) at which cardiovascular disease (CVD) and all-cause mortality risks are minimized in Japanese older adults with isolated systolic hypertension. We used data from the VALISH study (Valsartan in Elderly Isolated Systolic Hypertension) that recruited older adults (n=3035; mean age, 76 years) with systolic BP (SBP) of ≥160 mm Hg and diastolic BP of <90 mm Hg. Patients were treated by valsartan.

Effects of calcium channel blocker benidipine-based combination therapy on target blood pressure control and cardiovascular outcome: a sub-analysis of the COPE trial.

We compared three benidipine-based regimens-that is, benidipine plus angiotensin receptor blocker (ARB), β-blocker (BB) or thiazide-and found that the benidipine-BB combination was less beneficial in reducing the risk of stroke than the benidipine-thiazide combination. This sub-analysis sought to compare the effects of reaching a target blood pressure (BP) (<140/90 mm Hg) on the cardiovascular outcomes among the three benidipine-based treatment groups in the Combination Therapy of Hypertension to Prevent Cardiovascular Events trial. This sub-analysis included 3001 subjects to evaluate the achievement of target BP at a minimum of three points at 6-month intervals of clinical BP measurements during the study period.

Effects of calcium channel blocker-based combinations on intra-individual blood pressure variability: post hoc analysis of the COPE trial.

Visit-to-visit blood pressure (BP) variability is an important predictor of stroke. However, which antihypertensive drug combination is better at reducing visit-to-visit BP variability and therefore at reducing stroke incidence remains uncertain. We have previously reported that the dihydropyridine calcium channel blocker benidipine combined with a β-blocker appeared to be less beneficial in reducing the risk of stroke than a combination of benidipine and thiazide.

Preferable effects of olmesartan/calcium channel blocker to olmesartan/diuretic on blood pressure variability in very elderly hypertension: COLM study subanalysis.

Objective: The aims of this subanalysis of the COLM trial [NCT00454662] were to compare visit-to-visit variability (VVV) of blood pressure (BP) between age groups and between two treatment combinations, that is, the angiotensin II receptor blocker, olmesartan combined with a calcium channel blocker (CCB), or a diuretic and to investigate the effect of VVV of BP on cardiovascular events in elderly hypertensive patients.

Methods: Hypertensive patients ages 65-84 years with a history of and/or risk factors for cardiovascular disease were randomized to receive treatment with olmesartan along with either a CCB or a diuretic for at least 3 years. This subanalysis comprised 4876 patients who had their office BP measured at least three occasions (median nine occasions) during the follow-up period.

Combination therapy of hypertension in the elderly: a subgroup analysis of the Combination of OLMesartan and a calcium channel blocker or diuretic in Japanese elderly hypertensive patients trial.

Combination of OLMesartan and a calcium channel blocker or a diuretic in Japanese elderly hypertensive patients (COLM) trial demonstrated that olmesartan combinations with a CCB or diuretic have similar effects on reducing cardiovascular risk in elderly hypertensive patients. However, the safety profiles suggest that olmesartan combined with CCB may be preferable to olmesartan combined with diuretic. In this subgroup analysis, we further evaluated the effects and safety of these combinations in elderly (65-74 years old (y.

Comparison of olmesartan combined with a calcium channel blocker or a diuretic in elderly hypertensive patients (COLM Study): safety and tolerability.

The cardiovascular effects of combined therapy with the angiotensin receptor blocker (olmesartan) and a dihydropyridine calcium channel blocker (CCB) or a diuretic were compared in high-risk elderly Japanese hypertensive patients by performing a randomized, open label, blinded-endpoint study of morbidity and mortality (the COLM study). Here we report the results obtained with respect to safety and tolerability. High-risk hypertensive patients aged 65-84 years were enrolled and were randomized to receive olmesartan combined with either a CCB (amlodipine or azelnidipine) or a low-dose diuretic for at least 3 years.

A randomised controlled trial for the evaluation of risk for type 2 diabetes in hypertensive patients receiving thiazide diuretics: Diuretics In the Management of Essential hypertension (DIME) study.

Objectives: Thiazide diuretics are one of the first choice antihypertensives but not optimally utilised because of concerns regarding their adverse effects on glucose metabolism. The Diuretics In the Management of Essential hypertension (DIME) study was designed, for the first time, to assess the risk for type 2 diabetes mellitus in patients with essential hypertension during antihypertensive treatment with low-dose thiazide diuretics compared to those not treated with diuretics.

Design: Multicentre, unblinded, pragmatic, randomised, controlled trial with blinded assessment of end points and intention-to-treat analysis that was started in 2004 and finished in 2012.

Combinations of olmesartan and a calcium channel blocker or a diuretic in elderly hypertensive patients: a randomized, controlled trial.

Objective: The aim of the present study was to compare the cardiovascular effects of olmesartan, an angiotensin II receptor blocker, combined with a calcium channel blocker (CCB) or a diuretic, in a prospective, randomized, open-label, blinded endpoint trial.

Methods: Japanese hypertensive patients aged at least 65 to less than 85 years with SBP at least 140 mmHg and/or DBP at least 90 mmHg with antihypertensive treatment, or SBP at least 160 mmHg and/or DBP at least 100 mmHg without antihypertensive treatment were randomized to receive olmesartan with either a dihydropyridine CCB or a low-dose diuretic. If SBP and/or DBP remained at least 140 and/or at least 90 mmHg, the other antihypertensive drug was added.

Rho-kinase contributes to pressure-induced constriction of renal microvessels.

Renal afferent arterioles (AFF) regulate glomerular capillary pressure through two main mechanisms: the myogenic response (MYO) and tubuloglomerular feedback (TGF). Because Rho-kinase and nitric oxide synthase (NOS) are established factors that modulate vascular tone, we examined the role of these factors in pressure-induced AFF tone in Wistar-Kyoto rats and in spontaneously hypertensive rats (SHR) using an intravital CCD camera. Elevated renal perfusion pressure elicited marked AFF constriction that was partially inhibited by gadolinium, furosemide and fasudil, which inhibit MYO, TGF and Rho-kinase, respectively; however, this AFF constriction was completely blocked by combined treatment with fasudil+gadolinium or fasudil+furosemide.

Renal thrombotic microangiopathy in a patient with septic disseminated intravascular coagulation.

Background: The mechanism for the development of thrombotic microangiopathy (TMA) during sepsis has only been partially elucidated. TMA is recognized as a disease caused by various factors, and may be involved in the emergence of organ damage in severe sepsis. Here we report a case of TMA that followed disseminated intravascular coagulation (DIC) due to severe infection in a patient with a reduced ADAMTS-13 activity level.

Comparison of efficacy and safety between bisoprolol transdermal patch (TY-0201) and bisoprolol fumarate oral formulation in Japanese patients with grade I or II essential hypertension: randomized, double-blind, placebo-controlled study.

TY-0201 (TY) is a new drug absorbed by the transdermal delivery system developed for the treatment of hypertension, which contains the free base of bisoprolol fumarate that is widely used. An 8-week randomized, double-blind, placebo-controlled study was conducted in hypertensive patients to evaluate the superiority of TY 8 mg to placebo and the noninferiority of TY 8 mg to bisoprolol fumarate oral formulation (BO) 5 mg. Changes in diastolic blood pressure (BP) (primary endpoint) from baseline in the TY 8 mg group, the BO 5 mg group, and the placebo group were -12.

Effects of a benidipine-based combination therapy on the risk of stroke according to stroke subtype: the COPE trial.

The Combination Therapy of Hypertension to Prevent Cardiovascular Events (COPE) trial compared the dihydropyridine T/L-type calcium channel blocker benidipine-based therapies when combined with an angiotensin receptor blocker (ARB), a β-blocker (BB) or a thiazide diuretic (TD). The results suggested that benidipine combined with a BB appeared to be less beneficial in reducing the risk of stroke compared with the benidipine-TD combination (hazard ratio (HR): 2.31, P=0.

Combination therapy for hypertension in patients with CKD: a subanalysis of the Combination Therapy of Hypertension to Prevent Cardiovascular Events trial.

The Combination Therapy of Hypertension to Prevent Cardiovascular Events (COPE) trial was a multicenter, randomized, three-arm comparative study (N=3293) undertaken to determine the optimal combination therapy, based on the occurrence of cardiovascular events in patients treated with an angiotensin II receptor blocker (ARB), a β-blocker (BB) or a thiazide diuretic (TD) in addition to the calcium antagonist benidipine as baseline medication. This subanalysis was conducted to compare the efficacy of three combination therapies in a subset of 834 patients with chronic kidney disease (CKD) (287 patients treated with benidpine-ARB, 283 patients treated with benidipine-BB and 264 patients treated with benidipine-TD). The incidence of composite cardiovascular events as the primary end point did not differ among these three groups.

Anti-allergic effects of Vernonia amygdalina leaf extracts in hapten-induced atopic dermatitis-like disease in mice.

Background: Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by pruritic and eczematous skin lesions. In this study, AD-like disease was induced in NC/Nga mice so as to evaluate the anti-allergic effects of Vernonia amygdalina leaf extracts (VAM).

Methods: Forty NC/Nga mice were purchased for each of the two protocols (prophylactic and curative) of the study.

Combination therapy for hypertension in the elderly: a sub-analysis of the Combination Therapy of Hypertension to Prevent Cardiovascular Events (COPE) Trial.

The Combination Therapy of Hypertension to Prevent Cardiovascular Events (COPE) trial demonstrated that the calcium-channel blocker benidipine-based combination therapies with an angiotensin-receptor blocker (ARB), a β-blocker, or a thiazide diuretic (thiazide) were similarly effective in preventing cardiovascular events and achieving the target blood pressure (BP; <140/90 mm Hg). We further evaluated the efficacy and safety of these combination therapies in older (65 years) and younger (<65 years) hypertensive patients. In this sub-analysis of the COPE trial 3293 patients (153365 years old and 1760 <65 years old) were randomly assigned to receive benidipine-based therapy with an ARB, a β-blocker or a thiazide.

Importance of rostral ventrolateral medulla neurons in determining efferent sympathetic nerve activity and blood pressure.

Accentuated sympathetic nerve activity (SNA) is a risk factor for cardiovascular events. In this review, we investigate our working hypothesis that potentiated activity of neurons in the rostral ventrolateral medulla (RVLM) is the primary cause of experimental and essential hypertension. Over the past decade, we have examined how RVLM neurons regulate peripheral SNA, how the sympathetic and renin-angiotensin systems are correlated and how the sympathetic system can be suppressed to prevent cardiovascular events in patients.
