Barochiner J, Aparicio LS, Martínez R, Boggia J. Prognostic value of home blood pressure monitoring in patients under antihypertensive treatment. J Hum Hypertens 2023; 37:775-782. [PMID: 36163509 PMCID: PMC9510727 DOI: 10.1038/s41371-022-00758-x] [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: 05/29/2022] [Revised: 08/24/2022] [Accepted: 09/12/2022] [Indexed: 11/12/2022]
Abstract
The prognostic value of home blood pressure monitoring (HBPM) has been investigated in several studies in the general population, demonstrating its independent association with cardiovascular events. However, in the case of treated hypertensive subjects, evidence is controversial. Our purpose was to evaluate the prognostic value of HBPM in this population. Medicated hypertensive patients who performed a 4-day HBPM (Omron® HEM-705CP-II) between 2008 and 2015 were followed up for a median of 5.9 years, registering the occurrence of a composite primary outcome of fatal and non-fatal cardiovascular events. Cox regression models were used to analyze the prognostic value of HBPM, considering 4-day measurements, discarding the first day, and analyzing morning, afternoon and evening periods separately. We included 1582 patients in the analysis (33.4% men, median age 70.8 years, on an average of 2.1 antihypertensive drugs). During follow-up, 273 events occurred. HBPM was significantly associated with cardiovascular events in all five scenarios in the unadjusted models. When adjusting for office BP and other cardiovascular risk factors, the association remained marginally significant for the 4-day period, discarding first-day measurements HBPM (HR 1.04 [95% CI 1-1.1] and 1.04 [95% CI 1-1.1], respectively) and statistically significant for all separate periods of measurement: HR 1.32 (95% CI 1.01-1.72); 1.33 (95% CI 1.02-1.72); and 1.30 (95% CI 1.01-1.67), for morning, afternoon and evening, respectively. When analyzing separately fatal and non-fatal events, statistical significance was held for the former only. In conclusion, HBPM is an independent predictor of cardiovascular events in hypertensives under treatment.

Abstract
Asian countries are facing an increasing prevalence of metabolic syndrome (MetS), which may aggravate the burden of cardiovascular diseases in this region. MetS is closely associated with ambulatory blood pressure (BP). Patients with MetS, compared to those without, had a twofold higher risk of new-onset office, home, or ambulatory hypertension. Furthermore, the risk of new-onset MetS in patients with white-coat, masked and sustained hypertension was also doubled compared to normotensives. High-risk masked hypertension and blunted nighttime BP dipping are common in patients with MetS, suggesting perfect 24-hour BP control with long-acting antihypertensive drugs and early initiation of combination therapy might be especially important for patients with MetS.

Abstract
PURPOSE OF THE REVIEW Cellular circadian clocks regulate physiological functions during day and night. It has been convincingly demonstrated that hypertension in patients suffering from diabetes mellitus or metabolic syndrome is characterized in most cases by a disturbed 24-h profile resulting in a nondipper pattern. We consider possible correlation between biological clocks and symptoms of the metabolic syndrome. RECENT FINDINGS Changes in circadian clock function have been linked to metabolic disorders in genome-wide association studies. Epidemiological studies have shown that a loss of nocturnal decline in blood pressure increases the risk of cardiovascular morbidity and mortality and end-organ damage. Looking at clock genes, however, there is no obvious association between symptoms of diabetes or metabolic syndrome and clock gene expression. Emerging data suggest that circadian rhythm disruption is a risk factor for metabolic and cardiovascular disorders, while disease feedback on clock function is limited.

Abstract
: The aim of the current article is to review the current evidence on the role of morning blood pressure (BP) in the management of hypertension. Morning BP surge had been and will continue to be a hot topic of hypertension research. However, more evidence is needed to prove its clinical usefulness in the management of hypertension. Masked morning hypertension, as the other forms of masked hypertension, requires more research. The concept of morning BP monitoring could be clinically relevant in the therapeutic management of hypertension and in the prevention of cardiovascular complications by defining and treating morning hypertension. Antihypertensive medication is usually taken in the morning. The presence of uncontrolled morning BP during trough effect hours could be a hallmark of inadequate antihypertensive regimen, such as, for instance, the use of short-acting or intermediate-acting drugs, under dosing of drugs, or no or low use of combination therapy. To improve the management of hypertension in general and morning hypertension in particular, long-acting antihypertensive drugs should be used in appropriate often full dosages and in proper combinations. The clinical usefulness of antihypertensive drugs of specific mechanisms against morning BP or split or timed dosing of long-acting drugs in controlling morning BP remains under investigation. In conclusion, there is some evidence that morning BP is critical in the incidence of cardiovascular complications. However, proving its clinical usefulness in the management of hypertension requires further research.

Abstract
Morning blood pressure (BP) surge is an important aspect of hypertension research. Morning BP monitoring could be a clinically relevant concept in the therapeutic management of hypertension and in the prevention of cardiovascular complications by defining and treating morning hypertension. Because antihypertensive medication is often taken in the morning, uncontrolled morning BP during the trough effect hours could be a hallmark of inadequate choice of antihypertensive regimen, such as the use of short- or intermediate-acting drugs, underdosing of drugs, or no use or underuse of combination therapy. To improve the management of hypertension in general and morning hypertension in particular, long-acting antihypertensive drugs should be used in appropriate, often full dosages and in proper combinations. The clinical usefulness of antihypertensive drugs with specific mechanisms for morning BP or split or timed dosing of long-acting drugs in controlling morning BP remains under investigation.

Enhanced blood pressure-lowering effect of olmesartan in hypertensive patients with chronic kidney disease-associated sympathetic hyperactivity: HONEST study. J Clin Hypertens (Greenwich) 2013; 15:555-61. [PMID: 23889717 PMCID: PMC3884768 DOI: 10.1111/jch.12132] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2013] [Revised: 04/09/2013] [Accepted: 04/12/2013] [Indexed: 01/12/2023]
Abstract
To investigate the blood pressure (BP)–lowering effect of olmesartan in relation to chronic kidney disease (CKD)–associated sympathetic nerve activity, a subanalysis was performed using data from the first 16 weeks of the Home BP Measurement With Olmesartan‐Naive Patients to Establish Standard Target Blood Pressure (HONEST) study, a prospective observational study of hypertensive patients. Essential hypertensive patients who took no antihypertensive agent at baseline were classified based on baseline morning home systolic BP (MHSBP) in quartiles. In each class, patients were further classified based on baseline morning home pulse rate (MHPR). A subgroup analysis in patients with/without chronic kidney disease (CKD) was performed. A total of 5458 patients (mean age, 63.0 years; 51.6% women) were included. In the 4th quartile of baseline MHSBP (≥165 mm Hg), patients with MHPR ≥70 beats per minute had a greater BP reduction (by 3.2 mm Hg) than those with MHPR <70 beats per minute after 16 weeks of olmesartan‐based treatment (P=.0005). An even greater BP reduction (by 6.6 mm Hg) was observed in patients with CKD than in patients without CKD in this group (P=.0084). Olmesartan was more effective in hypertensive patients with high MHSBP and MHPR ≥70 beats per minute, especially in patients with CKD. Olmesartan may have enhanced BP‐lowering effects by improving renal ischemia in hypertensive CKD patients with potential increased sympathetic nerve activity.

Abstract
BACKGROUND AND OBJECTIVES Morning hypertension is closely related to target organ damage and cardiovascular events. Little data is available concerning the baseline characteristics and comprehensive blood pressure analysis of hypertensive patients on treatment with morning hypertension. SUBJECTS AND METHODS We evaluated 1,087 hypertensive patients who had taken stable anti-hypertensive medication at least 6 months. The enrolled patients measured their home blood pressure for 7 days. Baseline characteristics and the laboratory data were analyzed. Morning hypertension was defined as a morning blood pressure ≥135/85 mm Hg and systolic or diastolic blood pressure difference between morning and evening exceeding 10 mm Hg. RESULTS One hundred seventy three patients with morning hypertension showed a preponderance of males, older patients, alcohol consumers, and greater waist circumference and waist-to-hip ratio despite the same body mass index. Impaired fasting glucose and metabolic syndrome were more prevalent in the patients with morning hypertension. The morning hypertensives took more anti-hypertensive drugs and displayed higher blood pressure in the clinic and at home. CONCLUSION The worse clinical variables and relatively poorly controlled blood pressure of those with morning hypertension supports a potential relationship of morning hypertension with poor cardiovascular outcome. Morning blood pressure should be monitored at home for the optimal treatment of hypertension.

Abstract
The aim of the observational pharmaco-epidemiological study Optimax II was to seek whether the pre-existence of a metabolic syndrome (MS) defined by the NCEP-ATP III criteria impacts blood pressure (BP) control in hypertensive patients receiving a fixed perindopril/indapamide combination therapy. The primary objective of the study was to compare in patients with and without MS the rate of BP control defined as a systolic BP < or = 140 mmHg and a diastolic BP < or = 90 mmHg. Patients were prospectively included and the follow-up lasted 6 months. The study population consisted of 24,069 hypertensive patients (56% men; mean age 62 +/- 11 years; 18% diabetics; mean BP at inclusion 162 +/- 13/93 +/- 9 mmHg). MS was found in 30.4% of the patients (n = 7322): 35.2% women and 20.1% men. Three therapeutic subgroups were constituted: Group A, previously untreated, received the combination therapy as initial treatment; Group B, previously treated but with unsatisfactory results and/or treatment intolerance, had its previous treatment switched to perindopril/indapamide; and Group C, previously treated, with good treatment tolerance but uncontrolled BP, received the study treatment in adjunction to the previous one. The normalization rate was 70.3% in group A, 68.4% in Group B, and 64.1% in Group C (p < 0.0001). The pre-existence of MS did not show any significant influence on these rates since BP lowering was -22.7 +/- 13.7 (SBP) and -12.0 +/- 10.0 mmHg (DBP) in patients without MS and 22.6 +/- 13.3 (SBP) and -12.1 +/- 9.7 (DBP) in those with MS. The results of this study show a significant effect of perindopril/indapamide treatment on systolic BP lowering, whatever the treatment status: initiation, switch, or adjunctive therapy, and independently from the presence or not of MS. This effect may be related to the specific vascular effect of the perindopril/indapamide combination, which has recently demonstrated in the ADVANCE trial its ability to reduce mortality, and cardiovascular and renal complications in diabetic patients.

Abstract
OBJECTIVE We investigated the factors contributing to whether or not hypertensive patients brought their home blood pressure records to the outpatient clinic. METHOD We studied 325 hypertensive patients [169 men (66.3+/-11.4 years old) and 156 women (68.1+/-11.2 years old)] who had received medical treatment for hypertension in our outpatient clinic from June to August 2006. RESULTS Of the 325 patients studied, 206 (63.4%, 101 men, 105 women) brought their home blood pressure records to our outpatient clinic. Logistic analysis showed age [odds ratio (OR) =0.95; 95% confidence interval (CI): 0.93-0.98; p=0.0002], systolic blood pressure in outpatient clinic (OR=1.02; 95% CI: 1.00-1.04; p=0.0488) and the number of medicines prescribed (OR=1.94; 95% CI: 1.37-2.75; p=0.0002) were independent factors contributing to whether or not hypertensive patients bring along their home blood pressure records to the outpatient clinic. CONCLUSION The contributing factors determining whether the patients bring their home blood pressure records to the outpatient clinic were: younger age, higher systolic blood pressure in the outpatient clinic, and a higher number of antihypertensive drugs. In conclusion, our results suggest that physicians should further motivate older patients, with well-controlled blood pressure in the outpatient clinic, to bring their home blood pressure records to the outpatient clinic.

Abstract
It has been reported that the beta3-adrenergic receptor gene (ADRB3) is associated with abnormal metabolic risk factors. Therefore, we examined whether the Trp64Arg polymorphism of ADRB3 affects the occurrence of metabolic syndrome (MS). The participants were 2,395 subjects who underwent a medical examination in Shigaraki in Shiga, Japan. Among them, 1,416 subjects who gave informed consent for genetic analysis and were not receiving treatment for hypertension, diabetes, or hyperlipidemia were enrolled in this study. MS was diagnosed in 86 (16.0%) of 537 men, and 8 (0.9%) of 879 women. There was no significant relationship between ADRB3 polymorphism and the frequency of MS. Multiple logistic regression analysis including smoking, sex, and age as confounding factors showed no interaction between MS and ADRB3 polymorphism (odds ratio: 0.94; 95% confidence interval: 0.59-1.49; p=0.78). Subjects were also analyzed according to differences in the number of abnormal metabolic risk factors. However, there was no significant relationship between ADRB3 polymorphism and the number of such factors. In conclusion, in a general sample, the frequency of MS was 16.0% in men, and 0.9% in women. There was no relationship between ADRB3 polymorphism and MS.
