Ambulatory blood pressure

Motohisa Osaka
There are some reports that sympathetic nerve activity (SNA) shows a characteristic pattern a few hours before the onset of lethal ventricular arrhythmias. If so, it could be possible to predict sudden cardiac death a few hours in advance of its occurrence. Recently, we reported that a previously unidentified V-trough of SNA is a potential precursor of lethal cardiac events by examining 24-hour ambulatory electrocardiograms in which such an event was recorded by chance. In contrast, the chaotic nature of heart rate variability has been noted recently from the viewpoint of nonlinear dynamics...

Cardiovascular events are a major cause of early death in the Huntington's disease (HD) population. Dysautonomia as well as deterioration of circadian rhythms can be detected early in the disease progression and can have profound effects on cardiac health. The aim of the present study was to determine if HD patients and premanifest mutation carriers present a higher risk of cardiovascular disease (CVD) than non-mutation carrying controls METHODS: Prospective, cross-sectional, multicentre study of 38 HD mutation carriers (23 premanifest and 15 early-stage patients) compared to 38 age- and gender-matched healthy controls...

BACKGROUND: Increase in blood pressure (BP) variability (BPV) is associated with cardiovascular events, target organ damage, and arterial stiffness in adults. We previously reported that 24-h BPV may be associated with arterial stiffness and underlie white-coat hypertension (WCH). In this study, we examined whether visit-to-visit variability (VVV) could predict WCH and whether VVV correlated with eGFR, eGFR slope, and albuminuria/proteinuria in children and adolescents with renal diseases...

The 2017 American College of Cardiology/American Heart Association hypertension guidelines diagnose hypertension if systolic blood pressure (SBP) is ≥ 130 mmHg or diastolic blood pressure (DBP) is ≥ 80 mmHg. Increased BP is SBP 120-129 mmHg with DBP < 80 mmHg. Lifestyle measures should be used to treat individuals with increased BP. Lifestyle measures plus BP-lowering drugs should be used for secondary prevention of recurrent cardiovascular events in individuals with clinical cardiovascular disease (coronary heart disease, congestive heart failure, or stroke) and an average SBP ≥ 130 mmHg or an average DBP ≥ 80 mmHg...

Purpose of Review: This review will examine the implications for perioperative management of new hypertension guidelines and place these in the context of findings from recent large observational studies. Recent Findings: Recent hypertension guidelines highlight the role of ambulatory blood pressure measurement with the implication that isolated preoperative blood pressure measurements are of limited value. There is emerging evidence from large observational studies that both preoperative and intraoperative hypotension are associated with increased risk...

INTRODUCTION: Non-dipper and extreme dipper blood pressure (BP) profiles are associated with a worse cardiovascular prognosis. The relationship between nocturnal BP profile and hypertensive retinopathy (HR) is not fully established. AIM: To assess the association between the prevalence and severity of HR and nocturnal BP. METHODS: We prospectively studied hypertensive patients who underwent 24-hour ambulatory BP monitoring. The population was divided into two groups according to the presence or absence of lesions and compared according to baseline characteristics, nocturnal BP profile (dippers, non-dippers, inverted dippers/risers and extreme dippers) and mean nocturnal systolic (SBP) and diastolic (DBP) BP values...

Predictors of adverse cardiovascular outcomes include elevated nighttime systolic blood pressure (SBP) and a non-dipping pattern. We investigated whether these factors correlate with systemic inflammation, cardiovascular risk, and markers of central and peripheral vascular damage in rheumatoid arthritis (RA), a disease characterized by excess cardiovascular risk. Twenty-four-hour ambulatory blood pressure monitoring was applied in patients and controls. Vascular assessments included measurement of arterial stiffness (pulse wave velocity) and carotid atherosclerosis (carotid intima-media thickness)...
