Abstract
The aim of the present paper is to explore the option of chronotherapy of hypertension and its effectiveness in blood pressure (BP) lowering compared with its standard daily treatment. The treatment of BP has gone through many different schemes over the years. From no treatment in the early 1930s, to step care, to multiple drug combinations, or to single daily drug combinations with 2-3 drugs, still BP is not well controlled in a significant number of patients. Recently, the role of the circadian rhythm in the treatment of hypertension has been tested by several studies comparing the evening versus the morning drug administration with no clear evidence of superiority of either mode of drug administration. However, in cases of morning surge of BP, nocturnal hypertension, and renal disease, the evening drug administration has been more effective than the morning drug administration, and thus, more preferable. In order to get a better perspective on this approach of hypertension treatment, a Medline search of the English literature was contacted between 2010 and 2023 using the terms BP control, circadian rhythm, morning drug administration, evening drug administration, and 38 pertinent papers were selected for analysis. Careful review of the selected papers showed that chronotherapy of hypertension is effective. However, the overall effectiveness of evening drug administration compared with the morning administration is not significantly more effective compared to the morning administration and more work is needed in this field.

High dose cholecalciferol supplementation causing morning blood pressure reduction in patients with type 1 diabetes mellitus and cardiovascular autonomic neuropathy. Sci Rep 2024; 14:6374. [PMID: 38493259 PMCID: PMC10944468 DOI: 10.1038/s41598-024-56934-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Accepted: 03/12/2024] [Indexed: 03/18/2024] Open
Abstract
We evaluated the association of cardiovascular autonomic neuropathy (CAN), blood pressure (BP) and Vitamin D (VD) levels before and after high-dose cholecalciferol supplementation (4000/10,000) UI/day) for 12 weeks in patients (N = 67) with type 1 diabetes mellitus (T1DM). Based on this prospective controlled pilot study, patients were divided into group 1 (N = 23 with CAN) and group 2 (N = 44 without CAN). At baseline, group 1 had higher systolic BP (SBP) during sleep (115 ± 14 vs. 107 ± 12 mmHg, p = 0.04) and lower nocturnal dipping (3 ± 5 vs. 8 ± 6%, p = 0.009). Among those with loss of nocturnal dipping, 45.4% (20/44) had CAN, while in normal nocturnal dipping group it occurred only in 13% (3/23) (p = 0.007). Non-dipper group had worse CAN parameters when compared to dipper group [Very low frequency (VLF) (2.5 ± 0.5vs.2.8 ± 0.4 s, p = 0.01), total power (TP) (2.9 ± 0.6 vs. 3.3 ± 0.4 s, p = 0.01), Valsalva coefficient (1.5 ± 0.4 vs. 1.8 ± 0.6, p = 0.06)]. After VD, only group 1 improved CAN parameters [TP (2.5 ± 0.4 vs. 2.8 ± 0.6, p = 0.01) and VLF (2.2 ± 0.4 vs. 2.4 ± 0.5, p = 0.03). Group 1 presented a reduction in morning SBP (120 ± 20 vs. 114 ± 17 mmHg, p = 0.038) and in morning SBP surge (13 ± 13 vs. 5 ± 14, p = 0.04). High-dose VD was associated with improved CAN parameters and reduced awake SBP and morning SBP surge. These findings suggest that VD may benefit patients with cardiovascular autonomic neuropathy.

Abstract
The patient was a 63-year-old man with a 24-year history of hypertension. During long-term follow-up, when outpatient clinic blood pressure and morning blood pressure are well-regulated, exceptionally elevated early-morning blood pressure does not play a significant role in the development of hypertensive target organ disease or cardiovascular disease.

Hypertension 2023; 80:1417-1426. [PMID: 37315119 DOI: 10.1161/hypertensionaha.122.20589] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Accepted: 04/11/2023] [Indexed: 06/16/2023]
Abstract
BACKGROUND Sex differences in blood pressure control are recognized. We systematically investigated sex differences in specific components of ambulatory blood pressure (ABP), including variability, day-night changes, morning surge, and hypertension types. METHODS We analyzed ABPs of 52 911 participants (45.6% male, 54.4% female, 37.0% treated for hypertension) visiting 860 Italian community pharmacies. Sex differences in ABP levels and patterns were evaluated in the whole group and 4 risk groups (antihypertensive-treated patients, patients with diabetes, dyslipidemia, or cardiovascular disease). RESULTS Average 24-hour, day-time, and night-time blood pressure values were consistently higher in males than females (P<0.001). Variability in ABP was higher in females, except during the night. Nondippers and an abnormal morning surge were more common among males (odds ratio and 95% CI, 1.282 [1.230-1.335] and 1.244 [1.159-1.335]; P<0.001). The prevalence of 24-hour and masked hypertension was higher in males (odds ratio and 95% CI, 2.093 [2.019-2.170] and 1.347 [1.283-1.415]; P<0.001) and that of white-coat hypertension in females (0.719 [0.684-0.755]; P<0.001). Ambulatory heart rate mean values were higher (P<0.001) in females. Day-time HR variability was higher and night-time heart rate variability lower in females (P<0.001). Sex differences in ABP levels and patterns detected in the whole population were replicated in all risk groups, except for the prevalence of abnormal morning surge (between sexes difference in antihypertensive-treated participants only). CONCLUSIONS Females show better ABP control than males, but with an increased blood pressure variability and a greater prevalence of white-coat hypertension. These findings support tailored management of hypertension. REGISTRATION URL: https://www. CLINICALTRIALS gov; Unique identifier: NCT03781401.

Appropriate Circadian-Circasemidian Coupling Protects Blood Pressure from Morning Surge and Promotes Human Resilience and Wellbeing. Clin Interv Aging 2023; 18:755-769. [PMID: 37193339 PMCID: PMC10183193 DOI: 10.2147/cia.s398957] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Accepted: 05/02/2023] [Indexed: 05/18/2023] Open
Abstract
Background Blood pressure (BP) variability is involved in the appraisal of threat and safety, and can serve as a potential marker of psychological resilience against stress. The relationship between biological rhythms of BP and resilience was cross-sectionally assessed by 7-day/24-hour chronobiologic screening in a rural Japanese community (Tosa), with focus on the 12-hour component and the "circadian-circasemidian coupling" of systolic (S) BP. Subjects and Methods Tosa residents (N = 239, 147 women, 23-74 years), free of anti-hypertensive medication, completed 7-day/24-hour ambulatory BP monitoring. The circadian-circasemidian coupling was determined individually by computing the difference between the circadian phase and the circasemidian morning-phase of SBP. Participants were classified into three groups: those with a short coupling interval of about 4.5 hours (Group A), those with an intermediate coupling interval of about 6.0 hours (Group B), and those with a long coupling interval of about 8.0 hours (Group C). Results Residents of Group B who showed optimal circadian-circasemidian coordination had less pronounced morning and evening SBP surges, as compared to residents of Group A (10.82 vs 14.29 mmHg, P < 0.0001) and Group C (11.86 vs 15.21 mmHg, P < 0.0001), respectively. The incidence of morning or evening SBP surge was less in Group B than in Group A (P < 0.0001) or Group C (P < 0.0001). Group B residents showed highest measures of wellbeing and psychological resilience, assessed by good relation with friends (P < 0.05), life satisfaction (P < 0.05), and subjective happiness (P < 0.05). A disturbed circadian-circasemidian coupling was associated with elevated BP, dyslipidemia, arteriosclerosis and a depressive mood. Conclusion The circadian-circasemidian coupling of SBP could serve as a new biomarker in clinical practice to guide precision medicine interventions aimed at achieving properly timed rhythms, and thereby resilience and wellbeing.

Abstract
STUDY OBJECTIVES Previous observational studies have found conflicting evidence on the relationship between daytime napping and incident cardiovascular diseases (CVDs), but it remains unclear whether these associations present causality. This study aims to verify whether and why there is a causal relationship between these parameters, and whether there is an etiological basis. METHODS A two-sample Mendelian randomization analysis was performed using 79 single nucleotide polymorphisms associated with daytime napping. Summary-level data for coronary atherosclerosis, peripheral atherosclerosis, total CVD, and five CVD outcomes were obtained from the FinnGen study. Meta-analyses were aimed at investigating the relationships of excessive daytime napping with total CVD, coronary heart disease, myocardial infarction (MI), and stroke incidence. Subgroup, network meta-analysis (NMA) and trial sequential analysis (TSA) were also performed in this study. RESULTS The inverse-variance weighted method demonstrated that a genetic predisposition to more frequent daytime napping was significantly associated with higher odds of coronary atherosclerosis (odds ratio [OR] = 1.55, 95% confidence interval [CI]: 1.11 to 2.17), MI (OR = 1.63, 95% CI: 1.06 to 2.50), and heart failure (OR = 1.80, 95%CI: 1.28 to 2.52). In NMA, an increased risk of developing CVD in people who napped for more than 60 min a day than those who did not nap was demonstrated and then supported by TSA results (summary relative risk = 1.98, 95% CI: 1.39 to 2.82). CONCLUSION Habitual daytime napping is causally associated with an increased risk of incident CVD primarily via the development of coronary atherosclerosis. An average napping duration of more than 60 min is associated with an elevated risk of CVD in all participants.

Diagnostic agreement of masked uncontrolled hypertension detected by ambulatory blood pressure and home blood pressure measured by an all-in-one BP monitoring device: The HI-JAMP study. Hypertens Res 2023; 46:157-164. [PMID: 36229535 DOI: 10.1038/s41440-022-01073-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2022] [Revised: 09/27/2022] [Accepted: 09/29/2022] [Indexed: 02/03/2023]
Abstract
Masked hypertension is defined by office blood pressure (BP) in the controlled-BP range while out-of-office BP measured by ambulatory BP monitoring (ABPM) and home BP monitoring (HBPM) is in the uncontrolled range. However, diagnosis of masked hypertension may differ if assessed by different out-of-office BP indices. This study aims to investigate the diagnostic agreement of masked uncontrolled hypertension (MUHT) detected by ABPM indices (ABPM-MUHT) and HBPM indices (HBPM-MUHT) using the same all-in-one device (TM2441; A&D Company). The present study enrolled a total of 2322 treated hypertensive patients (males 53.2%, average age 69.2 ± 11.5 years) from the Home-Activity ICT-based Japan Ambulatory Blood Pressure Monitoring Prospective (HI-JAMP) Study, who consecutively underwent office BP monitoring, 24-h ABPM (at 30-min intervals), and 5-day HBPM (twice each morning and evening) using the same device. When out-of-office BP control status was assessed only by 24-h average SBP or by the average of morning and evening SBP, the diagnostic agreement of MUHT detected by ABPM and HBPM was 29.7% among the 445 patients with any type of MUHT. When out-of-office BP indices in each time-window were simultaneously assessed, the diagnostic agreement increased to 40-45.7%. Our results indicated the importance of assessing BPs at various times of day, especially morning hours, for perfect hypertension management. Diagnosis of masked hypertension only by an averaged BP index, without considering specific time-windows, might underestimate cardiovascular risk.

Abstract
There are limited comparison data throughout the dosing interval for generic versus brand metoprolol extended-release (ER) tablets. We compared the pharmacokinetics (PKs) and pharmacodynamics of brand name versus two generic formulations (drugs 1 and 2) of metoprolol ER tablets with different time to maximum concentration (Tmax ) in adults with hypertension. Participants were randomized to equal drug doses (50-150 mg/day) administered in one of two sequences (brand-drug1-brand-drug2 or brand-drug2-brand-drug1) and completed 24-h PK, digital heart rate (HR), ambulatory blood pressure (BP), and HR studies after taking each formulation for greater than or equal to 7 days. Metoprolol concentrations were determined by liquid chromatography tandem mass spectrometry, with noncompartmental analysis performed to obtain PK parameters in Phoenix WinNonlin. Heart rate variability (HRV) low-to-high frequency ratio was determined per quartile over the 24-h period. Thirty-six participants completed studies with the brand name and at least one generic product. Among 30 participants on the 50 mg dose, the primary PK end points of area under the concentration-time curve and Cmax were similar between products; Tmax was 6.1 ± 3.6 for the brand versus 3.5 ± 4.9 for drug 1 (p = 0.019) and 9.6 ± 3.2 for drug 2 (p < 0.001). Among all 36 participants, 24-h BPs and HRs were similar between products. Mean 24-h HRV low-to-high ratio was also similar for drug 1 (2.04 ± 1.35), drug 2 (1.86 ± 1.35), and brand (2.04 ± 1.77), but was more sustained over time for the brand versus drug 1 (drug × quartile interaction p = 0.017). Differences in Tmax between metoprolol ER products following repeated doses may have implications for drug effects on autonomic balance over the dosing interval.

Study on the Mechanism of Bu-Shen-He-Mai Granules in Improving Renal Damage of Ageing Spontaneously Hypertensive Rats by Regulating Th17 Cell/Tregs Balance. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:8315503. [PMID: 35502169 PMCID: PMC9056229 DOI: 10.1155/2022/8315503] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Revised: 04/01/2022] [Accepted: 04/02/2022] [Indexed: 01/11/2023]
Abstract
Methods Blood pressure and urine biochemical indices were recorded. Renal blood flow was evaluated by renal ultrasonography. Transmission electron microscopy (TEM) and HE staining were used to assess kidney and spleen morphology. Renal fibrosis was assessed using Masson staining. Serum levels of IL-6, IL-10, and IL-17A were measured using ELISAs. The density of RORγ and Foxp3 in the spleen was observed by immunofluorescence staining. The levels of Th17 cells and Tregs in blood were detected via flow cytometry. Transcriptome sequencing was performed to screen the targets of BSHM granules in hypertensive kidneys. Results BSHM granules decreased SBP by 21.2 mm·Hg and DBP by 8.8 mm·Hg in ageing SHRs (P < 0.05), decreased the levels of urine mALB, β2-Mg, and NAG (P < 0.01), and improved renal blood flow and arteriosclerosis. BSHM granules increased IL-10 expression (P < 0.05) while decreasing IL-6 (P < 0.01) and IL-17A (P < 0.05) levels. BSHM granules improved Foxp3 density and the number of Tregs (P < 0.01) and reduced RORγt density and the number of Th17 cells (P < 0.01). Transcriptome sequencing identified 747 differentially expressed (DE) mRNAs in kidneys after BSHM treatment. GO analysis suggested that BSHM granules act through immunoregulation. Conclusions BSHM granules attenuated hypertensive renal damage in ageing SHRs, by significantly increasing Tregs and decreasing Th17 cells.

Effects of isometric leg training on ambulatory blood pressure and morning blood pressure surge in young normotensive men and women. Sci Rep 2022; 12:356. [PMID: 35013400 PMCID: PMC8748906 DOI: 10.1038/s41598-021-04092-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2021] [Accepted: 11/30/2021] [Indexed: 11/18/2022] Open
Abstract
Despite the reported association between diurnal variations in ambulatory blood pressure (BP) and elevated cardiovascular disease risk, little is known regarding the effects of isometric resistance training (IRT), a practical BP-lowering intervention, on ambulatory BP and morning BP surge (MBPS). Thus, we investigated whether (i) IRT causes reductions in ambulatory BP and MBPS, in young normotensives, and (ii) if there are any sex differences in these changes. Twenty normotensive individuals (mean 24-h SBP = 121 ± 7, DBP = 67 ± 6 mmHg) undertook 10-weeks of bilateral-leg IRT (4 × 2-min/2-min rest, at 20% maximum voluntary contraction (MVC) 3 days/week). Ambulatory BP and MBPS (mean systolic BP (SBP) 2 h after waking minus the lowest sleeping 1 h mean SBP) was measures pre- and post-training. There were significant reductions in 24-h ambulatory SBP in men (− 4 ± 2 mmHg, P = 0.0001) and women (− 4 ± 2 mmHg, P = 0.0001) following IRT. Significant reductions were also observed in MBPS (− 6 ± 8 mmHg, p = 0.044; − 6 ± 7 mmHg, P = 0.019), yet there were no significant differences between men and women in these changes, and 24-h ambulatory diastolic BP remained unchanged. Furthermore, a significant correlation was identified between the magnitude of the change in MBPS and the magnitude of changes in the mean 2-h SBP after waking for both men and women (men, r = 0.89, P = 0.001; women, r = 0.74, P = 0.014). These findings add further support to the idea that IRT, as practical lifestyle intervention, is effective in significantly lowering ambulatory SBP and MBPS and might reduce the incidence of adverse cardiovascular events that often occur in the morning.

Abstract
Blood pressure (BP) usually rise from being asleep to awake, which is named the morning blood pressure surge (MBPS). Researches have reported that elevated MBPS was related with CV events, incident CKD in hypertensive patients. However, there have been no studies that have investigated the association between MBPS and renal or heart outcomes in patients with CKD and hypertension, in these patients, the MBPS is much lower because of high prevalence of night hypertension and reduced BP dipping. In this prospective two-center observational study, we enrolled patients with CKD and hypertension and the 24 h ambulatory blood pressure monitoring (ABPM) was conducted in all patients. Time to total mortality, CKD progression and CV events was recorded; Finally, a total of 304 patients were enrolled and 94 (30.9%) of them had elevated MBPS. After a follow-up for median 30 months, 23 (7.6%), 34 (11.2%), and 95 (31.3%) patients occurred death, CKD progression and new-onset CV events, respectively. The Cox regression analysis suggested the elevated MBPS was a strong predictor of CKD progression (HR 2.35, 95%CI 1.2 -4.63, p = .013), independent of morning BP, while no associations were found between elevated MBPS and CV events (HR 1.02, 95%CI 0.66 -1.57), as well as death (HR 1.08, 95%CI 0.46 -2.55). In conclusion, we provided the first evidence that elevated MBPS was an important risk factor of CKD progression in patients with CKD and hypertension. Appropriate evaluation and management of MBPS may be helpful to postpone CKD progression.

Abstract
BACKGROUND The morning blood pressure surge (MBPS) is related to an exaggerated risk of cardiovascular diseases and mortality. With increasing attention on circadian change in blood pressure and extensive use of ambulatory blood pressure monitoring (ABPM), chronotherapy that administration of medication according to biological rhythm, is reported to improve cardiovascular outcomes. The aim of this study is to evaluate the influence of chronotherapy of antihypertensive drugs upon MBPS in hypertensive patients. METHODS A search strategy was applied in Ovid MEDLINE, EMBASE, Cochrane (Wiley) CENTRAL Register of Controlled Trials, Cochrane Database of Systematic Reviews, and the Chinese Biomedical literature database. No language and date restrictions. Randomized controlled trials (RCT) assessing the efficacy of evening and morning administration of the same medications in adult patients with primary hypertension were included. RESULTS A total of ten trials, comprising 1724 participants with a mean age of 61 and 51% female, were included in this study. Combined analysis observed significant reduction of MBPS (- 5.30 mmHg, 95% CI - 8.80 to - 1.80), night-time SBP (- 2.29 mmHg, 95% CI - 4.43 to - 0.15), night-time DBP (- 1.63 mmHg, 95 %CI - 3.23 to - 0.04) and increase in night blood pressure dipping (3.23%, 95% CI 5.37 to 1.10) in evening dosage compared with traditional morning dosage of blood pressure-lowering drugs. No significant difference was found in the incidence of overall adverse effects (RR 0.65, 95% CI 0.30 to 1.41) and withdrawal due to adverse effects (RR 0.95, 95% CI 0.53 to 1.71). CONCLUSIONS Our study suggested that evening administration of antihypertensive medications exerted better blood pressure-lowering effect on MBPS compared with conventional morning dosage. Safety assessment also indicated that the evening regimen did not increase the risk of adverse events. However, endpoint studies need to be carried out to confirm the significance and feasibility of this treatment regimen in clinical practice.

Abstract
Endogenous circadian rhythms prepare the cardiovascular (CV) system for optimal function to match the daily anticipated behavioral and environmental cycles, including variable activities when awake during the day and recuperation when sleeping at night. The overall day-night patterns in most CV variables result from the summation of predictable circadian effects with variable behavioral and environmental effects on the CV system. The circadian system has also been implicated in the morning peak in the incidence of adverse CV events, including myocardial infarction, stroke, and sudden cardiac death. We discuss the resting and stress-reactive circadian control of CV physiology in humans and suggest future research opportunities, including improving CV therapy by optimally timing therapy relative to a person's internal body clock time.

Associations of the nocturnal blood pressure fall and morning surge with cardiovascular events and mortality in individuals with resistant hypertension. J Hypertens 2021; 39:1177-1187.

Abstract
OBJECTIVE The prognostic importance of the nocturnal blood pressure (BP) fall and early-morning surge were scarcely investigated in patients with resistant hypertension (RHT). We investigated them in a prospective cohort of 1726 RHT individuals. METHODS The nocturnal fall and morning surge were calculated from the baseline ambulatory BP monitoring (ABPM) and also as mean cumulative values using all ABPMs performed during follow-up. Dipping patterns (normal, extreme, reduced, and reverse) were defined by classic cut-off values of the night-to-day ratio, while MS (difference between early-morning and night-time BP) was categorized into quartiles and at the extremes of its distribution (5th, 10th, 90th, and 95th percentiles). The primary outcomes were total cardiovascular events (CVEs), major adverse cardiovascular events (MACEs), all-cause and cardiovascular mortalities. Multivariate Cox analyses examined the associations between nocturnal BP fall and morning surge and outcomes. RESULTS Over a median follow-up of 8.3 years, 417 CVEs occurred (358 MACEs), and 391 individuals died (233 cardiovascular deaths). Reduced and reverse dipping patterns were significant predictors of CVEs and MACEs, with hazard ratios between 1.6 and 2.5, whereas extreme dipping was a protective factor in younger individuals (hazard ratios 0.3--0.4) but a hazardous factor in elderly (hazard ratios 3.7--5.0) and in individuals with previous cardiovascular diseases (hazard ratios 2.6--4.4). No morning surge parameter was predictive of any outcome in fully adjusted analyses. CONCLUSION Abnormal dipping patterns but not the early-morning BP surge, were important prognostic markers for future cardiovascular morbidity in RHT patients. The prognosis of extreme dippers depended on age and the presence of cardiovascular diseases.

Abstract
BACKGROUND Vitamin D (VD) deficiency has been related to several endocrine metabolic and cardiovascular diseases. The effect of VD supplementation on blood pressure (BP) in patients with diabetes is controversial. OBJECTIVE The aim of this study was to evaluate high-dose vitamin D supplementation effects on blood pressure of normotensive patients with diabetes mellitus 1 (DM1) patients by 24-hour ambulatory blood pressure monitoring (ABPM). METHODS We performed a clinical trial including 35 DM1 normotensive patients, who received doses of 4,000 or 10,000 IU/day of cholecalciferol for 12 weeks according to previous VD levels. They underwent 24-hour ABPM, along with glycated hemoglobin, creatine, lipids profile and PCRus dosage before and after VD supplementation. RESULTS We found an expressive reduction of systolic and diastolic morning blood pressures (117±14 vs 112±14, p<0,05; 74±9 vs 70±10 mmHg, p<0,05, respectively) with no changes in other pressoric markers. Besides, we noticed a relationship between levels of VD after supplementation and diastolic morning blood pressure (r= -0,4; p<0.05). CONCLUSION Our study suggests an association between supplementation of high doses of vitamin D and the reduction of morning blood pressure in normotensive DM1 patients.

Abstract
BACKGROUND We performed this meta-analysis evaluating the efficacy of chronotherapy of hypertension with angiotensin receptor blockers (ARBs). METHODS We searched Pubmed, Web of Science, and Cochrane for all published randomized trials that compare antihypertensive effects of ARBs between bedtime dosing and awakening dosing. Blood pressure (BP) was measured by ambulatory BP monitoring in patients with mild or moderate essential hypertension. RESULTS The effects of ARBs on BP were assessed in 805 essential hypertensive patients included in 8 trials with a follow-up of 12 ± 3 weeks. The sleep-time systolic and diastolic BP (SBP, DBP) with bedtime dosing greatly decreased as compared with awakening dosing (weighted mean differences [WMD] for SBP WMD -5.23 [95% confidence intervals (CI), -7.27, -3.20] mm Hg, p < 0.001; WMD for DBP -2.94 [95% CI, -4.52, -1.36] mm Hg, p < 0.001). The reduction of daytime SBP (WMD 0.98 [95% CI, -0.20, 2.17] mm Hg, p = 0.10), DBP (WMD 0.11 [95% CI, -0.68, 0.89] mm Hg, p = 0.79), 24 hour SBP (WMD -0.75 [95% CI, -1.93, 0.42] mm Hg, p = 0.21) and DBP (WMD -0. 77 [95% CI, -1.55 0.01] mm Hg, p = 0.05) with bedtime dosing was similar with awakening dosing. CONCLUSIONS Bedtime dosing with ARBs is more effective in lowering sleep-time BP than awakening dosing in patients with essential hypertension, suggesting a utilization of chronotherapy of hypertension with ARBs to reduce sleep-time high BP. Larger multi-ethnic studies are needed to investigate the efficacy of chronotherapy of hypertension.
