[PMID: 38831091 DOI: 10.1038/s41440-024-01739-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Revised: 04/29/2024] [Accepted: 05/13/2024] [Indexed: 06/05/2024]
Abstract
The efficacy of renal denervation (RDN) has been controversial, but recent randomized sham-controlled trials demonstrated significant blood pressure reductions after RDN in patients with hypertension. We conducted a systematic review and updated meta-analysis to evaluate the effects of RDN on ambulatory and office blood pressures in patients with hypertension. Databases were searched up to 15 November 2023 to identify randomized, sham-controlled trials of RDN. The primary endpoint was change in 24 h ambulatory systolic blood pressure (SBP) with RDN versus sham control. The secondary endpoints were changes in 24 h ambulatory diastolic blood pressure, daytime and nighttime blood pressure (BP), office BP, and home BP. A sub-analysis determined outcomes by medication, procedure, and device. From twelve trials, 2222 patients with hypertension were randomized to undergo RDN (n = 1295) or a sham procedure (n = 927). At 2-6 months after treatment, RDN significantly reduced 24 h ambulatory SBP by 2.81 mmHg (95% confidence interval: -4.09, -1.53; p < 0.001) compared with the sham procedure. RDN also reduced daytime SBP by 3.17 mmHg (- 4.75, - 1.58; p < 0.001), nighttime SBP by 3.41 mmHg (- 4.69, - 2.13; p < 0.001), office SBP by 4.95 mmHg (- 6.37, - 3.54; p < 0.001), and home SBP by 4.64 mmHg (- 7.44, - 1.84; p = 0.001) versus the sham control group. There were no significant differences in the magnitude of BP reduction between first- and second-generation trials, between devices, or between with or without medication. These data from randomized sham-controlled trials showed that RDN significantly reduced all blood pressure metrics in medicated or unmedicated patients with hypertension, including resistant/uncontrolled hypertension.

Exploratory study on the relationship between urinary sodium/potassium ratio, salt intake, and the antihypertensive effect of esaxerenone: the ENaK Study. Hypertens Res 2024; 47:835-848. [PMID: 38212366 PMCID: PMC10994843 DOI: 10.1038/s41440-023-01519-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 10/30/2023] [Accepted: 11/05/2023] [Indexed: 01/13/2024]
Abstract
Excessive salt intake is one of the causes of hypertension, and reducing salt intake is important for managing the risk of hypertension and subsequent cardiovascular events. Esaxerenone, a mineralocorticoid receptor blocker, has the potential to exert an antihypertensive effect in hypertensive patients with excessive salt intake, but evidence is still lacking, especially in clinical settings. We aimed to determine if baseline sodium/potassium ratio and baseline estimated 24-h urinary sodium excretion can predict the antihypertensive effect of esaxerenone in patients with essential hypertension inadequately controlled with an angiotensin receptor blocker (ARB) or a calcium channel blocker (CCB). This was an exploratory, open-label, interventional study with a 4-week observation period and a 12-week treatment period. Esaxerenone was orally administered once daily in accordance with the Japanese package insert. In total, 126 patients met the eligibility criteria and were enrolled (ARB subcohort, 67; CCB subcohort, 59); all were included in the full analysis set (FAS) and safety analysis. In the FAS, morning home systolic blood pressure (SBP)/diastolic blood pressure (DBP) significantly decreased from baseline to end of treatment (primary efficacy endpoint) (-11.9 ± 10.9/ - 6.4 ± 6.8 mmHg, both p < 0.001); a similar trend was observed in both subcohorts. Significant reductions were also shown in bedtime home and office SBP/DBP (all p < 0.001). Each BP change was consistent regardless of the urinary sodium/potassium ratio or estimated 24-h urinary sodium excretion at baseline. The urinary albumin-creatinine ratio (UACR) and N-terminal pro-brain natriuretic peptide (NT-proBNP) significantly decreased from baseline to Week 12 in the total population and both subcohorts. No new safety concerns were raised. Esaxerenone significantly decreased morning home, bedtime home, and office BP; UACR; and NT-proBNP in this patient population, regardless of concomitant ARB or CCB use. The antihypertensive effect of esaxerenone was independent of the urinary sodium/potassium ratio and estimated 24-h urinary sodium excretion at baseline.

Abstract
Hypertension is a risk factor for cardiovascular disease (CVD). However, the association between blood pressure (BP) and CVD events has been based on mean BP alone. BP variability (BPV) is associated with increased organ damage and CVD events independently or beyond average home BP. To explain this association, we propose the systemic hemodynamic atherothrombotic syndrome (SHATS) hypothesis. The SHATS hypothesis indicates that hemodynamic stress increases vascular disease and vice versa, leading to a vicious cycle of the association between hemodynamic stress and a vascular disease; this association provides not only the risk but also the trigger for CVD events. The evidences of SHATS were gradually accumulating. We showed arterial stiffness synergistically amplified the association between hemodynamic stress and cardiac overload / CVD events in patients with at least one CVD risk factor.

Abstract
INTRODUCTION The EAGLE-DH study assessed the efficacy and safety of esaxerenone in hypertensive patients with diabetes mellitus receiving sodium-glucose cotransporter 2 (SGLT2) inhibitors. METHODS In this multicenter, open-label, prospective, interventional study, esaxerenone was started at 1.25 or 2.5 mg/day and could be gradually increased to 5 mg/day on the basis of blood pressure (BP) and serum potassium levels. Oral hypoglycemic or antihypertensive medications prior to obtaining consent was continued. Data were evaluated in the total population and creatinine-based estimated glomerular filtration rate (eGFR) subcohorts (eGFR ≥ 60 mL/min/1.73 m2 [G1-G2 subcohort] and 30 to < 60 mL/min/1.73 m2 [G3 subcohort]). RESULTS In total, 93 patients were evaluated (G1-G2, n = 49; G3, n = 44). Morning home systolic/diastolic BP values (SBP/DBP) were significantly reduced from baseline to week 12 (- 11.8 ± 10.8/- 5.1 ± 6.3 mmHg, both P < 0.001) and week 24 (- 12.9 ± 10.5/- 5.7 ± 6.3 mmHg, both P < 0.001). Similar results were observed in both eGFR subcohorts. The urinary albumin-to-creatinine ratio significantly decreased from baseline to week 24 in the total population (geometric percentage change, - 49.1%, P < 0.001) and in both eGFR subcohorts. The incidences of treatment-emergent adverse events (TEAEs) and drug-related TEAEs were 45.2% and 12.9%, respectively; most were mild or moderate. Serum potassium levels increased over the first 2 weeks of esaxerenone treatment, gradually decreased by week 12, and remained constant to week 24. One patient in the G1-G2 subcohort had serum potassium levels ≥ 5.5 mEq/L. No patients had serum potassium ≥ 6.0 mEq/L. CONCLUSION Esaxerenone effectively lowered BP, was safe, and showed renoprotective effects in hypertensive patients with diabetes mellitus receiving treatment with SGLT2 inhibitors. Esaxerenone and SGLT2 inhibitors did not interfere with either drug's efficacy and may reduce the frequency of serum potassium elevations, suggesting they are a compatible combination.

Hypertens Res 2023; 46:1684-1693.

Abstract
Few studies have investigated whether the prognostic power of home blood pressure (BP) for cardiovascular disease (CVD) events differs across subjects with different diabetic status. We used the dataset of the J-HOP (Japan Morning Surge-Home Blood Pressure) study, which enrolled patients having cardiovascular risks to investigate relationships between home BP and CVD events. We classified the patients as having diabetes mellitus (DM), prediabetes or normal glucose metabolism (NGM) as follows: for DM, a self-reported history of physician-diagnosed DM and/or use of DM medication, a fasting plasma glucose ≥126 mg/dL, a casual plasma glucose level ≥200 mg/dL or hemoglobin A1c (HbA1c) ≥6.5% (n = 1034); for prediabetes, HbA1c of 5.7-6.4% (n = 1167), and for NGM, those who remained (n = 2024). CVD outcome was defined as coronary artery disease, stroke or heart failure. During a median 6.2 ± 3.8 years of follow-up, 259 CVD events occurred. Analysis found both prediabetes (Unadjusted Hazard ratio [uHR], 1.43; 95% confidence interval [CI], 1.05-1.95), and DM (uHR, 2.13; 95% CI, 1.59-2.85) as risks of CVD compared to NGM. In DM, patients with a 10-mmHg elevation of office systolic BP (SBP) and morning home SBP had 16% and 14% higher risks for CVD events. In the prediabetes group, only an elevated morning home SBP conferred a risk of CVD events (uHR, 1.15; 95% CI, 1.00-1.31), but this association did not hold for the adjusted model. Like DM, prediabetes should be recognized as a risk for CVD events, albeit weakly. Elevated home BP contributes to increased CVD risk in diabetes. Our study demonstrated the impact of prediabetes and diabetes on CVD and the impact of office and home BP on CVD events in each group.

Abstract
We have previously shown that masked hypertension (MH) and sustained hypertension (SH) contribute to the progression of diabetic nephropathy. Although the risk of target organ damage and cardiovascular events in MH and SH is significantly higher than that in normotension and white coat hypertension, the role of MH or SH in cardiovascular events has never been reported in studies specific to diabetic patients. Therefore, in this study, we aimed to determine whether blood pressure control status contributes to the development of new cardiovascular events. A longitudinal study of 1082 patients with type 2 diabetes mellitus and no history of cardiovascular events was conducted. Patients were instructed to have their blood pressure measured three times, every morning and evening, for 14 consecutive days. Hypertension status was classified into four groups based on the systolic blood pressure measurements in the clinic and at home. The primary endpoint was the first cardiovascular event. After a median follow-up of 7.0 (interquartile range, 4.0-9.0) years, 119 patients developed cardiovascular events. The hazard ratio (95% confidence interval) for the risk of developing cardiovascular events was significantly higher in the SH group than in the controlled blood pressure group (1.63 [1.02-2.59]). SH is a useful predictor of cardiovascular events. Both at home and in the clinic, blood pressure monitoring should be assessed in routine clinical practice to predict future cardiovascular events in patients with type 2 diabetes.

Abstract
Home blood pressure measurement (HBPM) has the advantage of measuring blood pressure (BP) multiple times over a long period. HBPM effectively diagnoses stress-induced transient BP elevations (i.e., white coat hypertension), insufficient BP control throughout the day (i.e., masked hypertension), and even BP variability. In most cases, HBPM may increase self-awareness of BP, increasing the compliance of treatment. Cumulative evidence has reported better improved predictive values of HBPM in cardiovascular morbidity and mortality than office BP monitoring. In this position paper, the Korean Society of Hypertension Home Blood Pressure Forum provides comprehensive information and clinical importance on HBPM.

Imai Y. A personal history of research on hypertension From an encounter with hypertension to the development of hypertension practice based on out-of-clinic blood pressure measurements. Hypertens Res 2022; 45:1726-1742.

Abstract
In the 1970s, many people had severe hypertension and related cardiovascular and cerebrovascular diseases; however, antihypertensive treatments were not available at the time. The author encountered such conditions during the initial exposure to medicine. The author subsequently entered the field of hypertension medicine to prevent such conditions and engaged in hypertension research for more than 50 years. The author's central interest was the physiological and clinical aspects of blood pressure (BP) variability. Out-of-clinic BP measurements were the focus of clinical research. It was anticipated that self-measurement of BP at home (HBP) would improve medical practice surrounding hypertension. To establish evidence-based hypertension medicine, the Ohasama study (an epidemiology based on HBP) was conducted. The study provided firm evidence of the clinical significance of HBP and diagnostic criteria for hypertension and normotension. To establish target HBP levels for antihypertensive therapy, the Hypertension Objective treatment based on Measurement by Electrical Devices of Blood Pressure (HOMED-BP) study (a prospective intervention study) was also conducted. Application of HBP measurements expanded to obstetric, clinical pharmacology, pathophysiology, and genetic studies. During these studies, crucial information on the clinical significance of BP variability (such as circadian and day-by-day variation of BP, nocturnal BP, white-coat hypertension, and masked hypertension) was established. Finally, the author described the priority of HBP over clinic-measured BP for the diagnosis of hypertension in the 2014 Japanese Society of Hypertension Guidelines. In this article, the author's history of hypertension research, from the first encounter with hypertension to the construction of guidelines on hypertension, is reviewed.

Abstract
The method typically used to diagnose and monitor hypertensive patients has been to measure blood pressure in the physician's surgery; however, it is a well-known fact that this approach poses certain drawbacks, such as observer bias, failure to detect an alert reaction in the clinic, etc., difficulties that affect its accuracy as a diagnostic method. In recent years, the varying international scientific societies have persistently recommended the use of blood pressure measurements outside the clinic (at home or in the outpatient setting), using validated automatic devices. Data from some studies suggest that if we rely solely on in-office measurements, approximately 15-20% of the time we may be wrong when making decisions, both in terms of diagnosis and patient follow-up. Home blood pressure measurements are a simple and very affordable method that has a similar reproducibility and prognostic value as ambulatory blood pressure monitoring, the availability of which is currently very limited. Moreover, ambulatory self-measurements have the significant benefit of being able to improve control of hypertensive individuals. Healthcare professionals and patients should be aware of the methodology of home blood pressure measurement, its usefulness and limitations.

Abstract
OBJECTIVE No studies have demonstrated the association between urinary sodium-to-potassium (Na/K) ratio and all out-of-office blood pressure (BP) [home morning and evening BP (self-measured at home), and 24-h, daytime, and night-time ambulatory BP] in the same cohort. We aimed to assess, which type of out-of-office BP is more strongly associated with urinary Na/K ratio in the general population. METHODS This cross-sectional study was conducted in the general population of Ohasama, Japan. Home and ambulatory BP levels were measured, and 24-h urine samples were obtained from 875 participants (men, 25.5%; mean age, 60.1 years). The urinary Na/K ratio in the 24-h urine samples was calculated. RESULTS The median (interquartile range) urinary Na/K ratio was 4.19 (3.36-5.26). Significant positive trends of home morning, home evening, 24-h, and daytime SBP were observed across quartiles of urinary Na/K ratio (trend P ≤ 0.041; adjusted mean values between Q1 and Q4 of urinary Na/K ratio: 121.0-125.5 mmHg for home morning, 120.1-123.8 mmHg for home evening, 121.6-123.4 mmHg for 24-h, 127.5-129.5 mmHg for daytime). Urinary Na/K ratio was not significantly associated with office or night-time SBP and nocturnal BP fall (trend P ≥ 0.13). In the model with both home morning or evening SBP and daytime SBP, only home SBP was significantly associated with urinary Na/K ratio (P ≤ 0.048 for home SBP). CONCLUSION These findings suggest that urinary Na/K ratio might be more strongly associated with home BP than with 24-h and daytime BP but was not associated with night-time BP.

J Clin Hypertens (Greenwich) 2021; 23:1529-1537. [PMID: 34288371 PMCID: PMC8678810 DOI: 10.1111/jch.14327] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Revised: 06/07/2021] [Accepted: 07/07/2021] [Indexed: 11/28/2022]
Abstract
This study sought to investigate whether the relation between increased blood pressure (BP) variability and increased arterial stiffness confers a risk for cardiovascular disease (CVD) events. We analyzed 2648 patients from a practitioner‐based population (mean ± SD age 64.9 ± 11.4 years: 75.8% taking antihypertensive medication) with at least one cardiovascular risk factor who underwent home BP monitoring in the Japan Morning Surge‐Home Blood Pressure Study. The standard deviation (SDSBP), coefficient of variation (CVSBP), and average real variability (ARVSBP) were assessed as indexes of day‐by‐day home systolic BP (SBP) variability. The authors assessed arterial stiffness by brachial‐ankle pulse wave velocity (baPWV) and divided patients into lower (< 1800 cm/s, n = 1837) and higher (≥1800 cm/s, n = 811) baPWV groups. During a mean follow‐up of 4.4 years, 95 cardiovascular events occurred (8.1 per 1000 person‐years). In Cox proportional hazard models adjusted for traditional cardiovascular risk factors including average home SBP, the highest quartiles of SDSBP (hazard ratio [HR], 2.30; 95% confidence interval [CI], 1.23‐4.32), CVSBP (HR, 2.89; 95%CI, 1.59‐5.26) and ARVSBP (HR, 2.55; 95%CI, 1.37‐4.75) were predictive of CVD events compared to the other quartiles in the higher baPWV group. Moreover, 1SD increases in SDSBP (HR, 1.44; 95%CI, 1.13‐1.82), CVSBP (HR, 1.49; 95%CI, 1.16‐1.90) and ARVSBP (HR, 1.37; 95%CI, 1.09‐1.73) were also predictive of CVD events. These associations remained even after N‐terminal pro‐brain natriuretic peptide was added to the models. However, these associations were not observed in the lower baPWV group. We conclude that arterial stiffness contributes to the association between home BP variability and CVD incidence.

Response to exercise-induced blood pressure elevation is blunted in wrist-cuff automated oscillometric measurement in healthy young college students. Physiol Rep 2021; 8:e14570.

Abstract
Background A wrist‐cuff automated oscillometric device is portable and useful for self‐monitoring of blood pressure (BP) at home and outdoors when an upper arm device is not available. Although the height of the forearm in wrist BP measurement is acknowledged to be the major cause of measurement error, it remains unclear whether exercise affects subsequent wrist BP measurement. Methods and Results Ninety‐seven healthy college students (median age of 20 years with an age range of 19 to 36 years, 70.1% males) participated in this study. Care was taken to keep the position of the wrist at a level near the upper arm level in BP measurement. At rest, BP measured by a wrist‐cuff oscillometric device (Omron HEM‐6183) was generally acceptable when it was compared with BP measured by an upper arm oscillometric device (Omron HEM‐7130‐HP) and with BP measured by the auscultatory method using a mercury sphygmomanometer. However, the ratio of systolic BP measured by oscillometric devices just after a two‐step exercise test to that before exercise on the wrist (1.22 ± 0.14) was significantly lower than the ratio on the upper arm (1.27 ± 0.14), and the difference was significantly correlated with exercise‐induced increase in pulse rate (Spearman's ρ = 0.23), suggesting a possible role of autonomic nerve activity in the blunted response to exercise‐induced BP elevation in wrist BP measurement. Conclusions The results indicate that the blunted response to exercise‐induced BP elevation should be considered in wrist BP measurement when using a wrist‐cuff oscillometric device.

Abstract
Blood pressure (BP) is influenced by various factors, and it is known that temperature and BP have a negative relationship. However, few reports have examined the relationship between BP and temperature throughout the day in the same participant over time. Therefore, this study aimed to investigate the relationship between BP and temperature in the morning and evening in the same participants during a time period of ~1 year. In total, 401 participants, who participated in a community-based health checkup survey in Tarumizu, Japan, were enrolled. Five participants were excluded due to missing data. All participants measured their BP and the room temperature at home using a blood pressure monitor (HEM-9700T, OMRON Healthcare, Kyoto, Japan). The mean systolic BP (SBP) and diastolic BP (DBP) in the morning were significantly higher than the mean of the measurements taken in the evening (SBP: morning vs. evening 128 ± 15 mmHg vs. 122 ± 14 mmHg, P < 0.0001; DBP: morning vs. evening 77 ± 10 mmHg vs. 72 ± 8 mmHg, P < 0.0001). Using a linear mixed model with participants as a random effect, SBP and DBP were significantly associated with temperature in both the morning and evening. In the morning, in almost every month except July, a significant association between SBP and temperature was observed. However, there was a significant relationship between evening BP and temperature in all months. In conclusion, BP was significantly related to temperature in both the morning and evening during the year-long study. Furthermore, BP and temperature were significantly associated in all months except morning measurements in July.

Abstract
Increased blood pressure (BP) variability, an index of hemodynamic stress, leads to cardiac overload and worse cardiovascular prognosis. The association between day-by-day home BP variability and NT-proBNP (N-terminal pro-B-type natriuretic peptide) as an index of cardiac overload may be amplified by increased arterial stiffness as assessed by brachial-ankle pulse wave velocity (baPWV). J-HOP (Japan Morning Surge-Home Blood Pressure) Study participants who were selected from a practitioner-based population with at least one cardiovascular risk factor underwent home BP monitoring, and their BP levels and SD, coefficient of variation, and average real variability as indexes of systolic BP variability were assessed. We analyzed 2115 individuals without prevalent heart failure and divided them into lower (<1800 cm/s, n=1464) and higher (≥1800 cm/s, n=651) baPWV groups. The higher baPWV group had significantly higher SD

Abstract
The new 2019 Japanese Society of Hypertension (JSH) guidelines for the management of hypertension are now available; these update the previous guidelines published in 2014. The primary objective of the guideline is to provide all healthcare professionals with a standard management strategy and appropriate antihypertensive treatments to prevent hypertension-related target organ damage and cardiovascular events. The major changes in the new guideline relate to the definition of normal blood pressure (BP) and target BP. The terms 'normal BP' and 'high normal BP' used in the JSH 2014 guidelines are replaced with terms 'high normal BP' and 'elevated BP,' respectively. There was no change to the office BP diagnostic threshold for hypertension (140/90 mmHg). Recommended target office and home BP values for patients with hypertension aged <75 years and/or high-risk patients are <130/80 mmHg and <125/75 mmHg, respectively. Corresponding targets for elderly patients with hypertension (age≥75 years) are 140/90 and 135/85 mmHg, respectively. The goal is that these changes will contribute to reducing cardiovascular events, especially stroke and heart failure, in Japan. The dissemination of the JSH 2019 guidelines and implementation of a home BP-based approach by all general practitioners in Japan might be facilitated by digital hypertension management using health information technology.

Abstract
The aim of the present study was to examine whether dietary salt restriction guidance is beneficial for dietary salt restriction and lowering of home blood pressure in patients with diabetes with excessive salt intake. We performed an intervention trial of 37 people with type 2 diabetes and excessive salt intake. National registered dietitians provided dietary salt restriction guidance to each patient at the start of the study. All participants were instructed to perform triplicate morning and evening home blood pressure measurements using home blood pressure telemonitoring system. Daily salt intake at 2 months and 6 months was significantly lower than that at baseline; the difference was 0.8 [95% confidence interval (CI): 0.2–1.4, p = 0.009] g and 0.7 (95% CI: 0.1–1.3, p = 0.009) g, respectively. Morning systolic blood pressure at 2 months and 6 months was significantly lower than that at baseline; the difference was 2.7 (95% CI: 0.2–5.1, p = 0.034) mmHg and 5.8 (95% CI: 0.5–11.1, p = 0.034) mmHg, respectively. This intervention study revealed, for the first time, that dietary salt restriction guidance provided by a national registered dietitian is beneficial for reducing daily salt intake and home blood pressure in people with diabetes with excessive salt intake.

Abstract
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). Cardiovascular disease event risk was 6.32 events per 1000 person-years in the SPRINT population, which was higher than in the non-SPRINT low-risk (3.39; P<0.001) and lower than the SPRINT-excluded high-risk (12.41; P<0.001) populations. In the SPRINT and the SPRINT-excluded high-risk populations, a lower home SBP achieved was associated with lower cardiovascular disease risk, with the lowest risk in patients with a home SBP <125 mm Hg. The non-SPRINT low-risk population showed a J-curve association between on-treatment home SBP and cardiovascular disease risk with the lowest risk at a home SBP of 135 to <145 mm Hg. Intensive therapy targeting home SBP of <125 mm Hg would be beneficial for high-risk hypertensive patients. Clinical Trial Registration- URL: http://www.umin.ac.jp/ctr/index.htm .

Is antihypertensive treatment based on home blood pressure recommended rather than that based on office blood pressure in adults with essential hypertension? (meta-analysis).

Abstract
PURPOSE OF REVIEW To review data supporting the use of home blood pressure monitoring (HBPM) and provide practical guidance to clinicians wishing to incorporate HBPM into their practice. RECENT FINDINGS HBPM more accurately reflects the risk of cardiovascular events than office blood pressure measurement. In addition, there is high-quality evidence that HBPM combined with clinical support improves blood pressure control. Therefore, HBPM is increasingly recommended by guidelines to confirm the diagnosis of hypertension and evaluate the efficacy of blood pressure-lowering medications. Nevertheless, HBPM use remains low due to barriers from the patient, clinician, and healthcare system level. Understanding these barriers is crucial for developing strategies to effectively implement HBPM into routine clinical practice. HBPM is a valuable adjunct to office blood pressure measurement for diagnosing hypertension and guiding antihypertensive therapy. Following recommended best practices can facilitate the successful implementation of HBPM and impact how hypertension is managed in the primary care setting.

Predictive power of home blood pressure indices at baseline and during follow-up in hypertensive patients: HOMED-BP study. Hypertens Res 2018; 41:622-628.

Abstract
We compared the predictive power for a major adverse cardiovascular event (MACE) of four home blood pressure (BP) indices (systolic BP, diastolic BP, mean BP, and pulse pressure (PP)) obtained at baseline before treatment and during the on-treatment follow-up period in 3147 patients with essential hypertension (women: 50.1%, mean age: 59.5 years). Associations between MACE and each index were determined using Cox proportional hazard models and the likelihood ratio (LR) test. During a median follow-up of 5.4 years, 46 patients experienced MACE, which was a composite of cardiovascular death, non-fatal stroke, and non-fatal myocardial infarction. The LR test showed that systolic, diastolic, and mean BP during follow-up was more closely associated with cardiovascular risk than the corresponding indices at baseline (LR χ2 for baseline versus follow-up: systolic BP, (6.0, P = 0.014) versus (11.3, P = 0.0008); diastolic BP, (0.4, P = 0.53) versus (12.4, P = 0.0004); mean BP, (3.2, P = 0.074) versus (15.0, P = 0.0001)), whereas neither PP at baseline nor that during follow-up was significantly associated with MACE risk. Among home BP indices during follow-up, mean BP further improved prediction models in which systolic or diastolic BP was already included (P ≤ 0.042), but neither systolic nor diastolic BP improved models with mean BP (P = 0.80). In addition to home systolic and diastolic BP, mean BP during follow-up period provides essential information in predicting future cardiovascular diseases, whereas its utilization should be further assessed by an intervention trial targeting mean BP levels.

Abstract
Background The clinical significance of long‐term seasonal variations in self‐measured home blood pressure (BP) has not been elucidated for the cardiovascular disease prevention. Methods and Results Eligible 2787 patients were classified into 4 groups according to the magnitude of their seasonal variation in home BP, defined as an average of all increases in home BP from summer (July–August) to winter (January–February) combined with all decreases from winter to summer throughout the follow‐up period, namely inverse‐ (systolic/diastolic, <0/<0 mm Hg), small‐ (0–4.8/0–2.4 mm Hg), middle‐ (4.8–9.1/2.4–4.5 mm Hg), or large‐ (≥9.1/≥4.5 mm Hg) variation groups. The overall cardiovascular risks illustrated U‐shaped relationships across the groups, and hazard ratios for all cardiovascular outcomes compared with the small‐variation group were 3.07 (P=0.004) and 2.02 (P=0.041) in the inverse‐variation group and large‐variation group, respectively, based on systolic BP, and results were confirmatory for major adverse cardiovascular events. Furthermore, when the summer‐winter home BP difference was evaluated among patients who experienced titration and tapering of antihypertensive drugs depending on the season, the difference was significantly smaller in the early (September–November) than in the late (December–February) titration group (3.9/1.2 mm Hg versus 7.3/3.1 mm Hg, P<0.001) as well as in the early (March–May) than in the late (June–August) tapering group (4.4/2.1 mm Hg versus 7.1/3.4 mm Hg, P<0.001). Conclusions The small‐to‐middle seasonal variation in home BP (0–9.1/0–4.5 mm Hg), which may be partially attributed to earlier adjustment of antihypertensive medication, were associated with better cardiovascular outcomes.

Abstract
Over 50% of patients with diabetes mellitus, either type 1 or 2, ultimately develop hypertension as a complication. In diabetics, this further increases the incidence of cardiovascular disease (CVD) by 2- to 3-fold and accelerates the progression of diabetic nephropathy. Arteriosclerosis, a clinical feature of hypertension in diabetics, develops and advances from a young age. Therefore, in providing treatment, it is necessary to evaluate the degree of arteriosclerosis. Diabetic patients are encouraged to strictly control their blood glucose levels. Recently developed drugs, such as GLP-1 receptor agonists, DPP-4 inhibitors and SGLT2 inhibitors, also have hypotensive actions, making them ideal for use in diabetics with hypertension. SGLT2 inhibitors and GLP-1 receptor agonists reportedly suppress the onset and progression of CVD, as well as diabetic nephropathy. The possibility of hypoglycemia triggering blood pressure elevation and arrhythmia has been noted, so a key point here is not to cause hypoglycemia. In selecting hypotensive agents, we must choose types that do not aggravate insulin resistance and engage in hypotensive treatment that also considers both nocturnal and morning hypertension. In addition, facing the onset of an aging society, there is a growing need for treatments that do not cause excessive blood pressure reduction or hypoglycemia. Favorable lifelong blood pressure and glucose control are increasingly important for the treatment of diabetes accompanied by hypertension.

Abstract
The prevalence of both hypertension and diabetes mellitus is increasing worldwide. Both diseases lead to severe complications such as cardiovascular and chronic kidney diseases, which increase the risk of death over a long period of time. Therefore, the prevention and aggravation of hypertension and diabetes mellitus are major challenges. Because few review articles have focused on the epidemiological perspective of hypertension and diabetes mellitus, we reviewed major observational studies mainly from Japan and from Western countries that have reported on the prevalence of hypertension and diabetes mellitus, the binominal risk of hypertension and diabetes mellitus, and the risk of their coexistence. Our investigation found that approximately 50% of diabetic patients had hypertension, and approximately 20% of hypertensive patients had diabetes mellitus. Those with either hypertension or diabetes mellitus had a 1.5- to 2.0-fold higher risk of having both conditions. These results were similar for both Japan and Western countries. Although comparing the results between Japan and Western countries was difficult because the risks were estimated using widely varying statistical analyses, it was revealed that the coexistence of hypertension and diabetes mellitus certainly increased the risk of complications regardless of the country. The definition, prevalence and medical treatment of hypertension and diabetes mellitus will change in the future. For early intervention based on the latest evidence to prevent severe complications, it is important to accumulate epidemiological knowledge of hypertension and diabetes mellitus and to update the evidence for both Japan and other countries.

Abstract
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. Compared with well-controlled non-DM patients (MHSBP <135 mm Hg; CSBP <140 mm Hg), DM patients with WCH (MHSBP <135 mm Hg; CSBP ⩾140 mm Hg), MH (MHSBP ⩾135 mm Hg; CSBP <140 mm Hg) or poorly controlled hypertension (PCH) (MHSBP ⩾135 mm Hg; CSBP ⩾140 mm Hg) had significantly higher CV risk (hazard ratio (HR), 2.73, 2.77 and 2.81, respectively). CV risk was also significantly increased in CKD patients with WCH, MH and PCH (HR, 2.14, 1.70 and 2.20, respectively) compared with well-controlled non-CKD patients. Furthermore, DM patients had significantly higher incidence rate than non-DM patients of MHSBP ⩾125 to <135 mm Hg (HR, 1.98) and ⩾135 to <145 mm Hg (HR, 2.41). In conclusion, both WCH and MH are associated with increased CV risk, and thus control of both MHSBP and CSBP is important to reduce CV risk in DM or CKD patients. The results also suggest that even lower MHSBP (<125 mm Hg) may be beneficial for DM patients, although this conclusion is limited by the small number of patients.

Abstract
With increasing survival of patients infected with human immunodeficiency virus type 1 (HIV-1), the manifestation of heterogeneous neurological complications is also increasing alarmingly in these patients. Currently, more than 30% of about 40 million HIV-1 infected people worldwide develop central nervous system (CNS)-associated dysfunction, including dementia, sensory, and motor neuropathy. Furthermore, the highly effective antiretroviral therapy has been shown to increase the prevalence of mild cognitive functions while reducing other HIV-1-associated neurological complications. On the contrary, the presence of neurological disorder frequently affects the outcome of conventional HIV-1 therapy. Although, both the children and adults suffer from the post-HIV treatment-associated cognitive impairment, adults, especially depending on the age of disease onset, are more prone to CNS dysfunction. Thus, addressing neurological complications in an HIV-1-infected patient is a delicate balance of several factors and requires characterization of the molecular signature of associated CNS disorders involving intricate cross-talk with HIV-1-derived neurotoxins and other cellular factors. In this review, we summarize some of the current data supporting both the direct and indirect mechanisms, including neuro-inflammation and genome instability in association with aging, leading to CNS dysfunction after HIV-1 infection, and discuss the potential strategies addressing the treatment or prevention of HIV-1-mediated neurotoxicity.

Abstract
This study attempted to clarify the differences in blood pressure (BP) between the office (clinic) and home settings in patients with controlled, sustained, masked or white-coat hypertension. The following formula was used: office mean systolic BP (omSBP)-mean morning home SBP (mmhSBP)/office mean diastolic BP (omDBP)-mean morning home DBP (mmhDBP). The paired t-test was used for statistical analysis. The omSBP-mmhSBP/omDBP-mmhDBP calculation yielded the following results: among normotensive subjects, -1.1±11.2/-1.7±8.5 mm Hg (mean SBP and mean DBP were higher at home than in the office; n=451, P=0.038 in SBP, P=0.000 in DBP); in controlled hypertensive patients, -0.42±10.9/-2.2±8.2 mm Hg (n=1362, P=0.160 in SBP, P=0.000 in DBP); among sustained hypertensive patients, 5.6±14.7/0.048±9.9 mm Hg (n=1370, P=0.000 in SBP, P=0.857 in DBP); in masked hypertensive patients, -15.3±12.9/-9.3±9.5 mm Hg (n=1308, both P=0.000); and among white-coat hypertensive patients, 23.7±13.2/8.2±9.1 mm Hg (n=580, both P=0.000). Our results showed a difference of 5 mm Hg in SBP among sustained hypertensive patients, as recommended by the Japanese Society of Hypertension Guidelines for the Management of Hypertension; however, in other hypertensive patient types, the differences in SBP and DBP between office and home measurements differed by >5 mm Hg. Office and home BP measurements should be interpreted cautiously, keeping in mind the clinical setting.

Abstract
OBJECTIVES Home blood pressure control can reduce the risk of increased urinary albumin excretion in patients with diabetes mellitus. However, the optimal home blood pressure targets to prevent the onset or progression of diabetic nephropathy are not well defined. METHODS We performed a retrospective cohort study of 851 patients with type 2 diabetes mellitus. Logistic regression models were used to evaluate the correlations of home SBP levels with progression of diabetic nephropathy. RESULTS During the follow-up of 2 years, 86 patients had progression of diabetic nephropathy. Adjusted odds ratios (95% confidence interval) for progression of diabetic nephropathy in patients with morning SBP of 120-129 mmHg [2.725 (1.074-6.917), P = 0.035], 130-139 mmHg [3.703 (1.519-9.031), P = 0.004] and in those with morning SBP equal or more than 140 mmHg [2.994 (1.182-7.581), P = 0.021] were significantly higher than that in those with morning SBP less than 120 mmHg in multiple logistic analyses. CONCLUSION The preferable morning SBP targets might be less than 120 mmHg for preventing the onset or progression of diabetic nephropathy in patients with type 2 diabetes mellitus.

Abstract
Measurement of blood pressure (BP) by a doctor in the clinic has limitations that may result in an unrepresentative measure of underlying BP which can impact on the appropriate assessment and management of high BP. Home BP monitoring is the self-measurement of BP in the home setting (usually in the morning and evening) over a defined period (e.g. 7 days) under the direction of a healthcare provider. When it may not be feasible to measure 24-h ambulatory BP, home BP may be offered as a method to diagnose and manage patients with high BP. Home BP has good reproducibility, is well tolerated, is relatively inexpensive and is superior to clinic BP for prognosis of cardiovascular morbidity and mortality. Home BP can be used in combination with clinic BP to identify 'white coat' and 'masked' hypertension. An average home BP of at least 135/85 mmHg is an appropriate threshold for the diagnosis of hypertension. Home BP may also offer the advantage of empowering patients with their BP management, with benefits including increased adherence to therapy and lower achieved BP levels. It is recommended that, when feasible, home BP should be considered for routine use in the clinical management of hypertension.

Abstract
Background Recent literature suggests that blood pressure variability (BPV) predicts outcome beyond blood pressure level (BPL) and that antihypertensive drug classes differentially influence BPV. We compared calcium channel blockers, angiotensin‐converting enzyme inhibitors, and angiotensin receptor blockade for effects on changes in self‐measured home BPL and BPV and for their prognostic significance in newly treated hypertensive patients. Methods and Results We enrolled 2484 patients randomly allocated to first‐line treatment with a calcium channel blocker (n=833), an angiotensin‐converting enzyme inhibitor (n=821), or angiotensin receptor blockade (n=830). Home blood pressures in the morning and evening were measured for 5 days off treatment before randomization and for 5 days after 2 to 4 weeks of randomized drug treatment. We assessed BPL and BPV changes as estimated by variability independent of the mean and compared cardiovascular outcomes. Home BPL response in each group was significant (P≤0.0001) but small in the angiotensin‐converting enzyme inhibitor group (systolic/diastolic: 4.6/2.8 mm Hg) compared with the groups treated with a calcium channel blocker (systolic/diastolic: 8.3/3.9 mm Hg) and angiotensin receptor blockade (systolic/diastolic: 8.2/4.5 mm Hg). In multivariable adjusted analyses, changes in home variability independent of the mean did not differ among the 3 drug classes (P≥0.054). Evening variability independent of the mean before treatment significantly predicted hard cardiovascular events independent of the corresponding home BPL (P≤0.022), whereas BPV did not predict any cardiovascular outcome based on the morning measurement (P≥0.056). Home BPV captured after monotherapy had no predictive power for cardiovascular outcome (P≥0.22). Conclusions Self‐measured home evening BPV estimated by variability independent of the mean had prognostic significance, whereas antihypertensive drug classes had no significant impact on BPV changes. Home BPL should remain the primary focus for risk stratification and treatment. Clinical Trial Registration URL: http://www.umin.ac.jp/ctr/index.htm. Unique identifier: C000000137.

Abstract
OBJECTIVE The target levels of home-monitored blood pressure (BP) in patients with type 2 diabetes mellitus (T2DM) have not yet been established. We sought to examine the appropriate target home BP level in T2DM. METHODS This is a subanalysis of the Japan Morning Surge-Home Blood Pressure (J-HOP) study. We enrolled 4,310 patients who had at least 1 cardiovascular risk factor, and clinic and home BP monitoring was performed. The urinary albumin-to-creatinine ratio (UACR) was measured as a marker of microvascular disease. Quadratic equations of the relationship between clinic/home systolic BP (SBP) and log-transformed UACR were used to determine the home BP value. Home BP levels corresponding to clinic SBP/diastolic BP (DBP) level using the UACR values were calculated separately by the presence/absence of diabetes. RESULTS The mean age of the patients was 64.9±10.9 years; 47.0% were males. Of the 4,310 subjects enrolled, 1,057 (24.5%) had T2DM (the DM group) and 3,253 (75.5%) did not (non-DM group). The home BP levels equivalent to clinic BP 140/90 mm Hg were 135/84 and 135/83 mm Hg in the DM and non-DM groups, respectively. The home SBP levels equivalent to clinic SBP 130/80 mm Hg were 122/79 mm Hg in the non-DM group and 129/78 mm Hg in the DM group. CONCLUSIONS Regardless of diabetic status, the home BP level that corresponds to the clinic SBP 140/90 mm Hg was 135/85 mm Hg. In patients with T2DM, the home SBP level equivalent to clinic SBP 130/80 mm Hg was 129/78 mm Hg with regard to the extent of microvascular disease.

Abstract
The Japanese Society of Hypertension (JSH) published the new JSH guidelines for the management of hypertension in 2014, which is the revision of the JSH guidelines of 2009. The primary objective of the guideline is to provide physicians the standard treatment strategy of hypertension to prevent the hypertension-related target organ damage and cardiovascular events. The management of hypertension should be performed in hypertensive patients with a blood pressure of ≥140/90 mm Hg. As Asians have a higher prevalence of stroke than of coronary artery disease and stroke is more steeply associated with the level of blood pressure, the target blood pressure should be lower than 130/80 mm Hg for high-risk patients such as those with diabetes or chronic kidney disease. Because of the increasing prevalence of obesity and the related metabolic syndrome, more salt intake and higher salt sensitivity in the population, lifestyle modifications are necessary in hypertensive patients and subjects with high normal blood pressure. This guideline provides evidence-based recommendations for the management of patients with hypertension with the characteristics of our society.

Abstract
In patients with type 2 diabetes (T2DM), the coexistence of hypertension enhances the cardiovascular risk, and the prevention of future cardiovascular disease is an important component of T2DM management. Antihypertensive therapy has been shown to be an effective method of reducing the micro- and macrovascular complications of T2DM, however, the optimal target blood pressure (BP) levels are still under debate. Most of the international guidelines have raised the target clinic BP from 130/80 to 140/90 mmHg, however, the Japanese Society of Hypertension 2014 guidelines kept the target BP level at 130/80 mmHg. However, individualized BP-lowering treatments should be considered in patients with T2DM, especially in high-risk individuals such as those with a history of stroke or retinopathy, and aggressive antihypertensive therapy below 130 mmHg should be initiated even when the initial systolic BP level is <140 mmHg. The authors performed two studies concerning the BP target levels of home BP. In the first study, the authors found that a home BP target <125/75 mmHg was effective in improving the measures of vascular stiffness and kidney damage. In the second study, when the clinic BP target was set at 130/80 mmHg, the home BP could be approximately 130/80 mmHg. More data are needed to individualize the target BP levels of T2DM patients.

Abstract
Previous cross-sectional studies and 6-year longitudinal study have demonstrated that home blood pressure (HBP) measurements upon awakening have a stronger predictive power for death, micro- and macrovascular complications than clinic blood pressure (CBP) measurements in patients with type 2 diabetes (T2DM). This study investigated which of these measurements offers stronger predictive power for outcomes over 10 years. At baseline, 400 Japanese patients with T2DM were classified as having hypertension (HT) or normotension (NT) based on HBP and CBP. The mean survey duration was 95 months. Primary and secondary end-points were death and new or worsened micro- and macrovascular complications, respectively. Differences in outcomes for each end-point between HT and NT patients were analyzed using Kaplan-Meier survival curves and log-rank testing. Associated risk factors were assessed using Cox proportional hazards analysis. Based on HBP, death and micro- and macrovascular complications were significantly higher in patients with HT than with NT at baseline and end-point. Based on CBP, there were no significant differences in incidence of death, micro- or macrovascular complications between patients with HT and NT at baseline and end-point, although a significant difference in incidence of death was observed between the HT and NT groups at end-point. However, the significance was significantly lower in CBP than in HBP. One risk factor associated with micro- and macrovascular complications in patients with HBP was therapy for HT. This 10-year longitudinal study of patients with T2DM demonstrated that elevated HBP upon awakening is predictive of death, and micro- and macrovascular complications.
