The purpose of the study was to evaluate the degree of morning blood pressure surge (MBPS) and its relationship with markers of cardiovascular alterations in untreated middle-aged hypertensives. We studied 241 patients (mean age, 36.6 ± 10.7 years). Subjects with higher sleep-through MBPS (st-MBPS) were older (P = .003), had higher carotid intima-media thickness (cIMT) (P = .05) and lower E/A ratio (P = .01) than those with lower MBPS. Subjects with higher prewakening MBPS (pw-MBPS) had significantly higher deceleration time (P = ...

The ability of the arterial baroreflex to regulate blood pressure may influence the magnitude of the morning surge in blood pressure (MSBP). The aim was to investigate the relationships between sympathetic and cardiac baroreflex sensitivity (BRS) and the morning surge. Twenty-four hour ambulatory blood pressure was recorded in 14 young individuals. The morning surge was defined via the pre-awakening method, which is calculated as the difference between mean blood pressure values 2 h before and 2 h after rising from sleep...

OBJECTIVE: Prognosis of exaggerated morning surge (MS) of blood pressure (BP) remains controversial, possibly due to the ethnic difference in the size of MS. Compared to MS, evidence on morning hypertension (MH) is more consistent. With the use of a national BP registry database, we studied the size of MS and the prevalence and determinants of exaggerated MS and MH in Chinese. DESIGN AND METHOD: In the 3547 patients (mean age, 56.8 years; women, 49.1%; hypertension, 79...

OBJECTIVE: Morning blood pressure (BP) surge has been regarded as a predictor of adverse cardiovascular events. However, its determinants remain controversial and no previous studies have evaluated whether or not there is a difference in the determinants of morning BP surge between normotensive and hypertensive subjects. DESIGN AND METHOD: We included 476 normotensive subjects (mean age 52.8 ± 15.4 years, 49.2% males) and 1028 untreated hypertensive patients (age 51...

OBJECTIVE: Dynamic changes in 24-hour ambulatory blood pressure (BP) are associated with basal autonomic function and cardiovascular risk. We examined the influence of ethnicity on these parameters by comparing ambulatory BP dynamics in Japanese, African American (AA), and white populations with treatment-resistant hypertension. DESIGN AND METHOD: Both HTN-Japan (N = 41) and SYMPLICITY HTN-3 (N = 384 white and 140 AA) enrolled patients with office systolic BP ≥ 160 mmHg and 24-hour ambulatory systolic BP ≥ 135 mmHg while on ≥3 antihypertensive medications...

OBJECTIVE: No previous study addressed the relative contributions of environmental and genetic cues to the diurnal blood pressure rhythmicity. We firstly investigated the explained variance of environmental and clock genes in relation to the night-to-day ratio (NDR) and morning surge (MS), respectively. DESIGN AND METHOD: From 24-h ambulatory recordings of systolic blood pressure (SBP) obtained in untreated Chinese patients (51% women; mean age, 51 years), we computed NDR in 897 and MS in 637...

OBJECTIVE: The SPRINT (Systolic Blood Pressure Intervention Trial) recently demonstrated that strict blood pressure (BP) control resulted in a lower cardiovascular disease (CVD) risk compared to standard BP control, however, this association was not observed regarding the incidence of stroke. Previous studies revealed that the contribution of BP as a risk factor was higher for stroke incidence than for any other CVD, especially in Asian populations. It is thus not clear whether the results of the SPRINT can be generalized to all Asian populations...

The essential benefit of the management of hypertension is derived from the blood pressure (BP) lowering per se, indicating the importance of BP throughout 24 hours. Recent guidelines stressed the importance of home BP for the diagnosis and management of hypertension. It is well-known that cardiovascular events occur more frequently in the morning BP levels have been shown to increase during the period from night to early morning. Clinical research using ambulatory BP monitoring (ABPM) or home BP monitoring has clarified that morning BP and BP surge are more closely related to the cardiovascular risk than office BP (Kario et al...

Asians have specific characteristics of hypertension and related cardiovascular disease. Stroke is more common than coronary artery disease in Eastern Asian countries, while the coronary artery disease is more common than stroke in Western countries. The association slope between higher blood pressure (BP) and the risk of cardiovascular events is steeper in Asians than in Caucasians. This may partly explained by the recent result demonstrating that the morning BP surge in Asians is more extended (Hoshide, Kario, Parati et al...

Out-of-office blood pressure (BP) measured by home BP monitoring (HBPM) or ambulatory BP monitoring (ABPM) was demonstrated to be superior to office BP for the prediction of cardiovascular events. The ABPM is superior to HBPM for detecting the all the BP-related risks throughout 24-hr, and the self-measured HBPM underestimates the risk of daytime stress hypertension and nocturnal hypertension. However, ABPM cannot always be provided in clinical practice, and home BP monitoring can be superior to ABPM as part of a home BP-guided antihypertension strategy in clinical practice...

Out-of-office blood pressure (BP) measured by home BP monitoring, or ambulatory BP monitoring, was demonstrated to be superior to office BP for the prediction of cardiovascular events. The J-HOP study of a nationwide Japanese cohort demonstrated that morning home BP is the best stroke predictor. In the prospective HONEST study of >21 000 hypertensives, on-treatment morning home BP was shown to be a strong predictor both of future coronary artery disease and stroke events. In subjects whose office BP was maintained at ⩾150 mm Hg, there was no increase in cardiovascular events when their morning systolic BP was well-controlled at <125 mm Hg...

OBJECTIVE: Morning surge (MS) of peripheral blood pressure (BP) is considered to be an independent risk factor for cardiovascular diseases. However, central MS has not been analyzed so far. Therefore, the aim of the study was to evaluate the variables independently associated with central MS. DESIGN AND METHOD: Fifty never treated hypertensives (age 40.4 ± 11.5 years, 35 men) and 50 normotensive subjects (age 38.3 ± 12.0 years, 35 men) participated in the study...

OBJECTIVE: White-coat effect (WCE) and morning blood pressure surge (MBPS) are two particular phenomena assessable with ambulatory blood pressure monitoring (ABPM), that could have common pathophysiological mechanisms represented by an hyper-activation of the sympathetic nervous system. DESIGN AND METHOD: We examined the relationship between WCE and MPBS in 252 ABPM (M/F 94/158) characterized by WCE, i.e. when the first recorded value was at least 10 mmHg greater than the mean diurnal systolic blood pressure (SBP)...

There is growing evidence that diversely defined blood pressure variability (BPV) is an independent predictor of hypertensive target organ damage (TOD) and cardiovascular events. Several mechanisms have been speculated to underlie episodes of increased BPV, including the impairment of autonomic or hormonal regulation, renal dysfunction, and increased arterial stiffness. Within-home BPV, defined as differences in BP values obtained on a single occasion at home, could have prognostic significance for hypertensive TOD...

Underlying mechanisms of the elevated risks of hypertension and cardiovascular disease (CVD) in Cushing's syndrome (CS) are unclear. We treated an adult woman with CS because of a cortisol-secreting adrenal tumor. After tumor resection, the 24-h blood pressure (BP) level improved from 156/91 to 131/84 mmHg; the morning BP surprisingly improved from 174/98 to 127/93 mmHg, although we reduced her antihypertensive medication. Her sleep quality (by the Pittsburgh Sleep Quality Index) improved from 7 to 2 points...

Asians have specific characteristics of hypertension (HTN) and its relationship with cardiovascular disease. The morning surge in blood pressure (BP) in Asians is more extended, and the association slope between higher BP and the risk for cardiovascular events is steeper in this population than in whites. Thus, 24-hour BP control including at night and in the morning is especially important for Asian patients with HTN. There are 3 components of "perfect 24-hour BP control": the 24-hour BP level, adequate dipping of nocturnal BP (dipper type), and adequate BP variability such as the morning BP surge...

The independent prognostic significance of circadian blood pressure (BP) changes is unclear. We investigated the association between circadian BP changes and cardiovascular risk among elderly-treated hypertensive patients. The occurrence of a composite end point (that is, stroke, coronary events, heart failure and peripheral revascularization) was evaluated among 1191 elderly-treated hypertensive patients (age range 60-90 years). According to the nighttime change and the morning surge (MS) of systolic BP, subjects were divided into groups of dippers with a normal or high MS (DNMS and DHMS, respectively), non-dippers (ND), reverse dippers (RD) and extreme dippers with a normal or high MS (EDNMS and EDHMS, respectively)...

UNLABELLED: Our aim is to determine the optimal time schedule for home blood pressure (BP) monitoring that best predicts stroke and coronary artery disease in general practice. The Japan Morning Surge-Home Blood Pressure (J-HOP) study is a nationwide practice-based study that included 4310 Japanese with a history of or risk factors for cardiovascular disease, or both (mean age, 65 years; 79% used antihypertensive medication). Home BP measures were taken twice daily (morning and evening) over 14 days at baseline...

Long and short sleep durations were reported as independently associated with hypertension, aortic stiffness, and cardiovascular disease. High-sensitivity C-reactive protein (hs-CRP) was shown to be associated with increased aortic stiffness. Here, we investigated the relationship between self-reported sleep duration and pulse wave velocity (PWV) in the elderly at high risk of cardiovascular disease. We also investigated whether hs-CRP moderates this relationship. Among 4310 patients with ≥1 cardiovascular risks recruited for the Japan Morning Surge-Home Blood Pressure Study, a questionnaire including items on daily sleep duration was completed...
