RESUMEN
BACKGROUND: Serial blood pressure and heart rate measurements, particularly obtained by the patients at home, are currently recommended for the management of patients. METHODS: Home blood pressure and heart rate measurements were obtained by an 81-year old husband and his 74-year old wife in the morning and evening, over the course of an entire month. RESULTS: Morning and evening systolic blood pressure (129.9 ± 5.5, 125.9 ± 10.2, respectively), and diastolic blood pressure (69.2 ± 4.0, 70.1 ± 5.3) were not different (P > .05), heart rate (61.2 ± 2.9, 69.0 ± 5.5) was higher in the evening (P = .00001) in the husband, while systolic blood pressure (134.7 ± 9.6, 119.0 ± 12.0) and diastolic blood pressure (78.6 ± 5.6, 72.1 ± 7.3) were higher in the morning (P = .00001, P = .00031), and heart rate (62.7 ± 4.7, 68.2 ± 4.6) was higher in the evening (P = .00017) in the wife. CONCLUSIONS: Patient-generated serial home blood pressure and heart rate logs provide essential data for the patients' management and could potentially be useful in research; circadian variation of blood pressure and heart rate calls for implementation of chronotherapeutic principles for the time of drug administration.

BACKGROUND: Undiagnosed hypertension and uncontrolled blood pressure (BP) are common and contribute to excess cardiovascular morbidity and mortality. We examined whether BP control, changes in BP, and patient behaviors and attitudes were associated with a new hypertension diagnosis. METHODS: We performed a post hoc analysis of 323 participants from BP-CHECK (Blood Pressure Checks for Diagnosing Hypertension), a randomized diagnostic study of BP measuring methods in adults without diagnosed hypertension with elevated BP recruited from 12 primary care clinics of an integrated health care system in Washington State during 2017 to 2019. All 323 participants returned a positive diagnostic test for hypertension based on 24-hour ambulatory BP monitoring and were followed for 6 months. We used linear regression to examine the relationships between a new hypertension diagnosis (primary independent variable) and differences in the change in study outcomes from baseline to 6-month. RESULTS: Mean age of study participants was 58.3 years (SD, 13.1), 147 (45%) were women, and 253 (80%) were of non-Hispanic White race. At 6 months, 154 of 323 (48%) participants had a new hypertension diagnosis of whom 88 achieved target BP control. Participants with a new hypertension diagnosis experienced significantly larger declines from baseline in BP (adjusted mean difference: systolic BP, -7.6 mm Hg [95% CI, -10.3 to -4.8]; diastolic BP, -3.8 mm Hg [95% CI, -5.6 to -2.0]) compared with undiagnosed peers. They were also significantly more likely to achieve BP control by 6 months compared with undiagnosed participants (adjusted relative risk, 1.5 [95% CI, 1.1 to 2.0]). At 6 months, 101 of 323 participants (31%) with a positive ambulatory BP monitoring diagnostic test remained with undiagnosed hypertension, uncontrolled BP, and no antihypertensive medications. CONCLUSIONS: Approximately one-third of participants with high BP on screening and ambulatory BP monitoring diagnostic testing remained with undiagnosed hypertension, uncontrolled BP, and no antihypertensive medications after 6 months. New strategies are needed to enhance integration of BP diagnostic testing into clinical practice. REGISTRATION: URL: https://www.clinicaltrials.gov; Unique identifier: NCT03130257.

OBJECTIVE: The aim: The current study was designed for evaluation the effect of oral magnesium l-lactate supplementation on blood pressure and corrected QT interval in a sample of Iraqi women. PATIENTS AND METHODS: Materials and methods: In this interventional prospective randomized trial, 58 female patients diagnosed with MetS according to the International Diabetic Federation (IDF) criteria and were randomly allocated to receive either placebo or magnesium l-lactate 84 mg, twice daily. RESULTS: Results: O#ce blood pressure showed a signi$cant drop in systolic blood pressure (SBP) (P<0.05), non-significant decline in diastolic blood pressure (DBP), heart rate (HR), and pulse pressure (PP) (P>0.05), while ambulatory blood pressure monitoring (ABPM) recorded a signi$cant reduction in HR in patients on magnesium supplement. Also, there was a signi$cant decline in the SBP (P<0.05) and non-signi$cant decline in DBP and PP (P>0.05) in patients with masked hypertension on Mg supplement. The changes in corrected QT- interval had no signi$cant e"ect within Mg group (P>0.05). CONCLUSION: Conclusions: From above results, one can conclude that oral Mg l-lactate supplement can improve, to a certain extent, blood pressure of women with MetS. Further studies in this aspect may be required.

BACKGROUND: Accurate blood pressure (BP) measurement is essential to identify and manage hypertension. Prior studies have reported a difference between BP measured in routine patient care and in research studies. We aimed to investigate the agreement between BP measured in routine care and research-grade BP in Kaiser Permanente Southern California, a large, integrated healthcare system with initiatives to standardize BP measurements during routine patient care visits. METHODS: We included adultsâ ≥65 years old with hypertension, taking antihypertensive medication, and participating in the Ambulatory Blood Pressure in Older Adults (AMBROSIA) study in 2019-2021. Clinic BP from routine care visits was extracted from the electronic health record. Research-grade BP was obtained by trained AMBROSIA study staff via an automatic oscillometric device. The mean difference between routine care and research-grade BP, limits of agreement, and correlation were assessed. RESULTS: We included 309 participants (mean age 75 years; 54% female; 49% non-Hispanic white). Compared with measurements from routine care, mean research-grade systolic BP (SBP) was 0.1 mm Hg higher (95% CI: -1.5 to 1.8) and diastolic BP (DBP) was 0.4 mm Hg lower (95% CI: -1.6 to 0.7). Limits of agreement were -29 to 30 mm Hg for SBP and -21 to 20 mm Hg for DBP. The intraclass correlation coefficient was 0.42 (95% CI: 0.33 to 0.51) for SBP and 0.43 (95% CI: 0.34 to 0.52) for DBP. CONCLUSIONS: High within-person variation and moderate correlation were present between BP measured in routine care and following a research protocol suggesting the importance of standardized measurements.

Several prospective studies consistently report elevated asleep blood pressure (BP) and blunted sleep-time relative systolic BP (SBP) decline (non-dipping) are jointly the most significant prognostic markers of cardiovascular disease (CVD) risk, including heart failure (HF); therefore, they, rather than office BP measurements (OBPM) and ambulatory awake and 24 h BP means, seemingly are the most worthy therapeutic targets for prevention. Published studies of the 24 h BP pattern in HF are sparse in number and of limited sample size. They report high prevalence of the abnormal non-dipper/riser 24 h SBP patterning. Despite the established clinical relevance of the asleep BP, past as do present hypertension guidelines recommend the diagnosis of hypertension rely on OBPM and, when around-the-clock ambulatory BP monitoring (ABPM) is conducted to confirm the elevated OBPM, either on the derived 24 h or "daytime" BP means. Additionally, hypertension guidelines do not advise the time-of-day when BP-lowering medications should be ingested, in spite of known ingestion-time differences in their pharmacokinetics and pharmacodynamics. Between 1976 and 2020, 155 unique trials of ingestion-time differences in the effects of 37 different single and 14 dual-combination hypertension medications, collectively involving 23,972 patients, were published. The vast majority (83.9%) of them found the at-bedtime/evening in comparison to upon-waking/morning treatment schedule resulted in more greatly enhanced: (i) reduction of asleep BP mean without induced sleep-time hypotension; (ii) reduction of the prevalence of the higher CVD risk non-dipper/riser 24 h BP phenotypes; (iii) improvement of kidney function, reduction of cardiac pathology, and with lower incidence of adverse effects. Most notably, no single published randomized trial found significantly better BP-lowering, particularly during sleep, or medical benefits of the most popular upon-waking/morning hypertension treatment-time scheme. Additionally, prospective outcome trials have substantiated that the bedtime relative to the upon-waking, ingestion of BP-lowering medications not only significantly reduces risk of HF but also improves overall CVD event-free survival time.

The most important factor in treating hypertension is assessing an individual patient's true blood pressure load, the cornerstone being research-grade office determination. Office blood pressure should be supplemented with out-of-office measurement, including home and ambulatory monitoring (if available), which we consider complementary and not interchangeable. Controversy remains for initiation of treatment of white coat hypertension, where cardiovascular risk lies between normotension and sustained hypertension; antihypertensive therapy should be considered unless low cardiovascular risk, wherein pressures should be followed for progression to sustained hypertension. Available data do not support intensification of therapy for the white coat effect due to the similar cardiovascular risk to controlled hypertension. Given the higher cardiovascular risk of the masked effect, initiation of therapy for masked hypertension and intensification for masked uncontrolled hypertension are indicated, acknowledging the dearth of supporting data. Optimally, randomized controlled trials are needed to determine the benefit of treating the 4 incongruous phenotypes between office and out-of-office measurements, that is, those with white coat or masked effects. We make no recommendations regarding chronotherapy pending results of ongoing trials.

In the last 4 years, several evidence-based, national, and international guidelines on the management of arterial hypertension have been published, mostly with concordant recommendations, but in some aspects with discordant opinions. This in-depth review takes these guidelines into account but also addresses several new data of interest. Although being somewhat obvious and simple, accurate blood pressure (BP) measurement with validated devices is the cornerstone of the diagnosis of hypertension, but out-of-office BP measurements are of crucial importance as well. Simplified antihypertensive drug treatment such as single-pill combinations enhances the adherence to medication and speeds up the process of getting into the BP target range, a goal not so far adequately respected. Recommended (single-pill) combination therapy includes diuretics as part of the first step of antihypertensive therapy, and updated analysis does not provide evidence to exclude diuretics from this first step because of the recently discussed potential risk of increasing cancer incidence. Target BP goals need to be individualized, according to comorbidities, hypertension-mediated organ damage, coexistence of cardiovascular risk factors (including age), frailty in older patients, and individual tolerability. There are also concordant recommendations in the guidelines that an office BP between 120 and 140 mm Hg systolic and between 70 and 80 mm Hg diastolic should be achieved. The BP target of Kidney Disease: Improving Global Outcomes for hypertensive patients with chronic kidney disease are not applicable for clinical practice because they heavily rely on 1 study that used a study-specific, nontransferable BP measurement technique and excluded the most common cause of chronic kidney disease, namely, diabetic nephropathy. Actual data even from a prospective trial on chronotherapy have to be disregarded, and antihypertensive medication should not be routinely dosed at bedtime. Rigorously conducted trials justify the revival of renal denervation for treatment of (at least, but not only) uncontrolled and treatment-resistant hypertension.

BACKGROUND: It is well known that morning blood pressure surge increases the risk of myocardial events in the first several hours post-awakening. This meta-analysis was performed to compare the antihypertensive efficacy of morning and bedtime dosing on decreasing morning blood pressure surge. METHODS: Articles in 4 databases about clinical trials of ingestion time of antihypertensive drugs were searched and performed a meta-analysis to evaluate the different effects on morning blood pressure and absolute blood pressure (BP) reduction from baseline of between bedtime administration (experimental group) and morning awaking administration (control group). RESULTS: The aim of this study is to compare the antihypertensive efficacy of morning and bedtime dosing on decreasing morning blood pressure surge. CONCLUSIONS: The bedtime will provide evidence support for clinicians and patients for reducing morning blood pressure surge. ETHICS AND DISSEMINATION: This study does not require ethical approval.

Physical exercise and isoflavone supplementation are potential strategies to prevent and treat cardiovascular diseases in postmenopausal women. The aim of this study was to investigate whether there are additive effects of isoflavone supplementation when associated with combined aerobic and resistance exercise on resting and ambulatory blood pressure monitoring (ABPM) and in blood pressure variability (BPV). Thirty-one non-obese postmenopausal women were randomly allocated into two groups: placebo and exercise (Placebo n = 19); and isoflavone supplementation (100 mg/day) and exercise (isoflavone n = 19). ABPM and BPV were evaluated before and after 10 weeks of moderate combined (aerobic and resistance) exercise training. Generalized Estimating Equation (GEE) with Bonferroni correction and intention-to-treat analysis was used to compare the effects of interventions on resting BP, ABPM and BPV. Combined exercise training decreased resting systolic (SBP) and diastolic blood pressure (DBP) and reduced 24 h and awake ambulatory SBP, DBP and mean blood pressure over time, with no additional effects of isoflavone supplementation. No changes were observed in sleep period, or in BPV indexes (Standard Deviation of 24 h (SD), daytime and nighttime interval (SDdn) and average real variability (ARV) in both groups. We conclude that isoflavone supplementation does not potentiate the effects of combined training on resting and ambulatorial systolic and diastolic blood pressure in non-obese postmenopausal women.

A case of a 59-year-old man with resistant hypertension, despite 8 months of non-pharmacological and pharmacological management up to maximal doses of triple antihypertensive therapy. Review of the literature found a study that reported improved blood pressure control with bedtime dosing of antihypertensive treatment. Changing to bedtime dosage of antihypertensives resulted in significant improvement in blood pressure control to below target levels. This highlights the importance of the clinicians' awareness and implementation of research findings and hence delivery of best evidence-based care.

OBJECTIVES: To investigate whether the manipulation parameter of the twirling frequency in acupuncture affects the blood pressure when acupuncture is applied on the acupoints ST9 and LR3 in a human body. DESIGN: A randomized, controlled trial. INTERVENTIONS: A hundred and twenty patients with hypertension were randomized into four treatment groups. A twirling frequency of 120 twirls per minute or 60 twirls per minute were respectively applied on the acupoints ST9 or LR3. Each patient received five acupuncture sessions a week over a period of 12 weeks, with a follow-up period of a further12 weeks. The outcome was assessed by using an ambulatory blood pressure monitor. RESULTS: A hundred and twenty twirls per minute on ST9 could overall improve the BP (24hDBP, mSBP, mDBP, dDBP, nSBP and nDBP). Sixty twirls per minute on ST9 improved the 24hDBP, dSBP, dDBP and mDBP; 120 twirls per minute on LR3 did not show any anti-hypertensive effect, while 60 twirls per minute on LR3 improved the dSBP and dDBP. The results indicated that the acupuncture effect on BP, the onset of anti-hypertensive effect, the occurrence of the effect, and the duration of the effect depended on the frequency of needle manipulation on the same acupuncture point. CONCLUSIONS: As one of the important factors of the effects of acupuncture, the manipulation parameter's impact has its specificity for different acupoints. Thus, in the future, close attention needs to be paid to this clinically. TRIAL REGISTRATION: Chinese Clinical Trial Registry: Chi CTR-TRC-12002582.

In a multicenter, randomized trial, we investigated whether the long half-time dihydropyridine calcium channel blocker amlodipine was more efficacious than the gastrointestinal therapeutic system (GITS) formulation of nifedipine in lowering ambulatory blood pressure (BP) in sustained hypertension (clinic systolic/diastolic BP 140-179/90-109 mm Hg and 24-hour systolic/diastolic BP ≥ 130/80 mm Hg). Eligible patients were randomly assigned to amlodipine 5-10 mg/day or nifedipine-GITS 30-60 mg/day. Ambulatory BP monitoring was performed for 24 hours at baseline and 4-week treatment and for 48 hours at 8-week treatment with a dose of medication missed on the second day. After 8-week treatment, BP was similarly reduced in the amlodipine (n = 257) and nifedipine-GITS groups (n = 248) for both clinic and ambulatory (24-hour systolic/diastolic BP 10.3/6.5 vs 10.9/6.3 mm Hg, P ≥ 0.24) measurements. However, after missing a dose of medication, ambulatory BP reductions were greater in the amlodipine than nifedipine-GITS group, with a significant (P ≤ 0.04) between-group difference in 24-hour (-1.2 mm Hg) and daytime diastolic BP (-1.5 mm Hg). In conclusion, amlodipine and nifedipine-GITS were efficacious in reducing 24-hour BP. When a dose of medication was missed, amlodipine became more efficacious than nifedipine-GITS.

OBJECTIVES: This preliminary study tested whether a high-dose, sustained-release form of melatonin reduced 24-hour blood pressure in African-Americans. DESIGN: Randomized, placebo-controlled, crossover pilot study of 40 self-defined African-American patients with essential hypertension. SETTINGS/LOCATION: Urban, academic medical center and associated outpatient clinics. INTERVENTIONS: Patients ingested either melatonin (high dose [24 mg], sustained-release formulation] or placebo in randomized order over a 4-week period. OUTCOME MEASURES: Mean nighttime and daytime systolic and diastolic blood pressures, as measured with 24-hour ambulatory blood pressure monitors. The primary outcome was mean nighttime systolic blood pressure. RESULTS: There were no statistically differences between melatonin and placebo conditions in mean nighttime or daytime systolic or diastolic blood pressures. CONCLUSIONS: In contrast with studies in other populations, this preliminary study showed that nighttime dosing of continuous-release melatonin had no significant effect on nocturnal blood pressure in African Americans with essential hypertension when compared to placebo.

Acupuncture may be beneficial for patients with mild hypertension, but the evidence is not convincing. We aimed to examine the effect of acupuncture on blood pressure (BP) reduction in patients with mild hypertension. We conducted a multicenter, single-blind, sham-controlled, randomized trial in eleven hospitals in China. The trial included 428 patients with systolic blood pressure (SBP) from 140 to 159 mm Hg and/or with diastolic blood pressure (DBP) from 90 to 99 mm Hg. The patients were randomly assigned to receive 18 sessions of affected meridian acupuncture (n = 107) or non-affected meridian acupuncture (n = 107) or sham acupuncture (n = 107) during 6 weeks, or to stay in a waiting-list control (n = 107). All patients received 24-hour ambulatory blood pressure monitoring at weeks 6, 9, and 12. We included 415 participants in the intention-to-treat analysis. The two acupuncture groups were pooled in the analysis, since they had no difference in all outcomes. SBP decreased at week 6 in acupuncture group vs sham acupuncture vs waiting-list group (7.2 ± 11.0 mm Hg vs 4.1 ± 11.5 mm Hg vs 4.1 ± 13.2 mm Hg); acupuncture was not superior to sham acupuncture (mean difference 2.7 mm Hg, 95% CI 0.4 to 5.9, adjusted P = 0.103) or waiting-list control (2.9 mm Hg, 95% CI -0.2 to 6.0, adjusted P = 0.078). However, acupuncture was superior to sham acupuncture (3.3 mm Hg, 95% CI 0.2 to 6.3, adjusted P = 0.035) and waiting-list control (4.8 mm Hg, 95% CI 1.8 to 7.8, P < 0.001) at week 9. Acupuncture had a small effect size on the reduction of BP in patients with mild hypertension.

Baroreflex activation therapy (BAT) is approved for the treatment of resistant hypertension. In addition to blood pressure (BP) reduction, pilot studies suggested several organoprotective effects of BAT. Thirty-two patients with resistant hypertension were prospectively treated with BAT. Besides office BP and 24-hour ambulatory BP (ABP) measurements, detection of a urinary proteome-based classifier (CKD273), which has been shown to predict chronic kidney disease (CKD) progression, was carried out at baseline and after 6 months of BAT. Office BP significantly decreased from 170 ± 25/90 ± 18 to 149 ± 29/82 ± 18 mm Hg. Analysis of CKD273 score and eGFR with CKD-EPI equation at baseline revealed strong correlation (r = 0.568, P < 0.001). After 6 months of BAT, there was no significant change in CKD273 score (-0.061 [95% CI: -0.262 to 0.140], P = 0.601). However, by stratification of the data regarding ABP response, there was a statistically significant (P = 0.0113) reduction in the CKD273 score from a mean of 0.161 [95% CI: -0.093 to 0.414] to -0.346 [95% CI: -0.632 to -0.060] after BAT in patients with systolic ABP decrease of ≥5 mm Hg. These data emphasized potential nephroprotective effects of BAT in patients with sufficient BP response.

OBJECTIVE: Essential hypertension (EH) is the most common chronic disease in the United States and a major cause of morbidity and mortality. Lifestyle interventions (e.g., diet, exercise, stress management) to reduce blood pressure (BP) are often complex with varying effectiveness. Breathing awareness meditation (BAM) is a stress management strategy with encouraging effects on BP, though widespread dissemination is hampered by the lack of an easy-to-use methodology to train and monitor BAM practices. A smartphone application (Tension Tamer [TT]) that implements BAM and tracks adherence has shown promise in addressing these gaps. This 6-month dose-response feasibility trial evaluated effects of the app on BP to further optimize BAM user guidelines. METHODS: Sixty-four adults with prehypertension were randomized to complete TT-guided BAM sessions for 5-, 10-, or 15-min intervals twice daily over 6 months. Continuous heart rate readings derived from the phone's video camera via reflective photoplethysmography were used as feedback and as an index of time-stamped adherence. Outcomes (resting BP, HR) were collected at baseline, 1-, 3-, and 6-months. RESULTS: Mixed modeling results showed a significant time effect for systolic BP (SBP) with a dose-response effect at Months 3 and 6. Adherence declined over time and was lowest in the 15-min dose condition, though SBP reductions were maintained. Generally, adherence was negatively associated with dose as the study progressed. CONCLUSIONS: Smartphone-implemented BAM appears to reduce SBP and can be a low-cost method to reach large populations. (PsycINFO Database Record

Diagnosis of hypertension-elevated blood pressure (BP) associated with increased cardiovascular disease (CVD) risk-and its management for decades have been based primarily on single time-of-day office BP measurements (OBPM) assumed representative of systolic (SBP) and diastolic BP (DBP) during the entire 24-hours span. Around-the-clock ambulatory blood pressure monitoring (ABPM), however, reveals BP undergoes 24-hours patterning characterized in normotensives and uncomplicated hypertensives by striking morning-time rise, 2 daytime peaks-one ~2-3 hours after awakening and the other early evening, small midafternoon nadir and 10-20% decline (BP dipping) in the asleep BP mean relative to the wake-time BP mean. A growing number of outcome trials substantiate correlation between BP and target organ damage, vascular and other risks is greater for the ABPM-derived asleep BP mean, independent and stronger predictor of CVD risk, than daytime OBPM or ABPM-derived awake BP. Additionally, bedtime hypertension chronotherapy, that is, ingestion of ≥1 conventional hypertension medications at bedtime to achieve efficient attenuation of asleep BP, better reduces total CVD events by 61% and major events (CVD death, myocardial infarction, ischaemic and haemorrhagic stroke) by 67%-even in more vulnerable chronic kidney disease, diabetes and resistant hypertension patients-than customary on-awaking therapy that targets wake-time BP. Such findings of around-the-clock ABPM and bedtime hypertension outcome trials, consistently indicating greater importance of asleep BP than daytime OBPM or ambulatory awake BP, call for a new definition of true arterial hypertension plus modern approaches for its diagnosis and management.

BACKGROUND: Yoga seems to exert its effect against arterial hypertension mainly through the associated breathing and meditation techniques, and less so through yoga postures. The goal of this trial was to compare the blood pressure-lowering effect of yoga interventions with and without yoga postures in patients with arterial hypertension. METHODS: 75 patients taking medications for arterial hypertension (72% women, mean age 58.7 ± 9.5 years) were randomized into three groups: a yoga intervention group with yoga postures (25 patients, of whom 5 dropped out of the trial before its end), a yoga intervention group without yoga postures (25 patients, 3 dropouts), and a wait list control group (25 patients, one dropout). The interventions consisted of 90 minutes of yoga practice per week for twelve weeks. The data collectors, who were blinded to the intervention received, assessed the primary outcome measures "systolic 24-hour blood pressure" and "diastolic 24-hour blood pressure" before and after the intervention. In this report, we also present the findings on secondary outcome measures, including follow-up data. RESULTS: After the intervention, the systolic 24-hour blood pressure in the yoga intervention group without yoga postures was significantly lower than in the control group (group difference [Δ]= -3.8 mmHg; [95% confidence interval (CI): (-0.3; -7.4) p = 0.035]); it was also significantly lower than in the yoga intervention group with yoga postures (Δ = -3.2 mmHg; 95% CI: [-6.3; -0.8]; p = 0.045). Diastolic blood pressures did not differ significantly across groups. No serious adverse events were encountered in the course of the trial. CONCLUSION: In accordance with the findings of earlier studies, we found that only yoga without yoga postures induced a short-term lowering of ambulatory systolic blood pressure. Yoga is safe and effective in patients taking medications for arterial hypertension and thus can be recommended as an additional treatment option for persons in this category.

The aim of this study was to compare the effect of morning and bedtime administration of valsartan/amlodipine combination therapy (80/5 mg) on nocturnal brachial and central blood pressure (BP) measured by ambulatory BP monitoring in patients with hypertension. This was a 16-week prospective, multicenter, randomized, open-label, crossover, noninferiority clinical trial. Patients underwent 24-hour ambulatory BP monitoring at randomization, at switching, and at the end of the study. Twenty-three patients (mean age, 68.0 years) were studied. The difference in nocturnal brachial systolic BP between the morning and bedtime administrations of combination valsartan/amlodipine was -3.2 mm Hg, and the two-sided 95% confidence interval ranged from -6.8 to 0.4 mm Hg. The difference in nocturnal central systolic BP was -4.0 mm Hg (95% confidence interval, -7.6 to -0.4 mm Hg). The upper limit of the 95% confidence interval was below the margin of 3.0 mm Hg in both nocturnal brachial and central systolic BP, confirming the noninferiority of morning administration to the bedtime administration of valsartan/amlodipine combination therapy.
