BACKGROUND Prediabetes (PreDM) in asymptomatic adults is associated with abnormal circadian blood pressure variability (abnormal CBPV). HYPOTHESIS Systemic inflammation and glycemia influence circadian blood pressure variability. METHODS Dahl salt-sensitive (S) rats (n = 19) after weaning were fed either an American (AD) or a standard (SD) diet. The AD (high-glycemic-index, high-fat) simula...

Affecting 1 billion people worldwide, hypertension remains the most common, readily identifiable, and reversible risk factor for myocardial infarction, stroke, heart failure, atrial fibrillation, aortic dissection, and peripheral arterial disease. Because of escalating obesity and population aging, the global burden of hypertension is rising and projected to affect 1.5 billion persons—one third...

See Articles pages 364 and 374 Although great advances have been made in stroke medicine in the past two decades, some questions about treatment in the acute phase of stroke remain. One such question is how to manage blood pressure? Blood pressure is often increased in acute ischaemic and haemorrhagic stroke, and fi ndings from epidemiological studies suggest that high blood pressure in the acu...

It has been shown previously that endogenous nitric oxide can buffer arterial blood pressure variability in dogs and rats. In these former studies, all isoforms of the nitric oxide synthase were blocked pharmacologically and an increased blood pressure variability was observed. Thus the question as to which isoform of the nitric oxide synthase is responsible for the blood pressure buffering eff...

Systolic blood pressure variability is an independent risk factor for mortality and cardiovascular events. Standard measures of blood pressure predict outcome poorly in haemodialysis patients. We investigated whether systolic blood pressure variability was associated with mortality in incident haemodialysis patients. We performed a longitudinal observational study of patients commencing haemodi...

Recent data suggest that visit-to-visit variability of blood pressure is associated with stroke incidence. Correlates of increased visit-to-visit variability in blood pressure and the relationship between variability and all-cause mortality were examined using data on US adults ≥ 20 years of age from the Third National Health and Nutrition Examination Survey (n = 956). Three consecutive blood p...

The objective of this study was to determine the effect of aging on beat-to-beat blood pressure and pulse interval variability in resting conditions and to determine the effect of aging on the sympathetic and vagal influence on the cardiovascular system by power spectral analysis of blood pressure and pulse interval. We studied three groups of healthy, normotensive subjects: young (10 to 15 yea...

OBJECTIVE The objective of the present study was to observe the relation between blood pressure variability (BPV) and early renal damage in hypertensive patients. PATIENTS AND METHODS A total of 118 hypertensive patients were consecutively selected. General parameters including sex, age, duration, and grade of hypertension, antihypertensive drugs taken, smoking status, blood sugar, blood lipi...

BACKGROUND Cardiac amyloidosis due to familial amyloid polyneuropathy (FAP) includes restrictive cardiomyopathy, thickened cardiac walls, conduction disorders and cardiac denervation. Impaired blood pressure variability has been documented in FAP related to the Val30Met mutation. AIMS To document blood pressure variability in FAP patients with various mutation types and its relationship to th...

Day-by-day blood pressure and heart rate variability defined as within-subject SDs of home measurements can be calculated from long-term self-measurement. We investigated the prognostic value of day-by-day variability in 2455 Ohasama, Japan, residents (baseline age: 35 to 96 years; 60.4% women). Home blood pressure and heart rate were measured once every morning for 26 days (median). A total of...
