Clinical Relevance of Day-by-Day Blood Pressure and Heart Rate Variability

Day-by-Day Variability of Blood Pressure and Heart Rate at Home as a Novel Predictor of Prognosis

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...

Day-to-day blood pressure variability and dementia

Day-by-Day Blood Pressure Variability and Functional Outcome After Acute Ischemic Stroke: Fukuoka Stroke Registry.

BACKGROUND AND PURPOSE The relationship between blood pressure (BP) variability and functional outcome in patients with acute ischemic stroke remains unclear. This study aimed to elucidate whether in-hospital day-by-day BP variability is associated with functional outcome after acute ischemic stroke. METHODS Using the Fukuoka Stroke Registry, we included 2566 patients with a first-ever ischem...

Day-by-day blood pressure variability: cause or consequence of vascular brain injury?

D ementia represents an important public health issue in developed countries because of increasing longevity of the elderly population. 1 Cerebral damage is mediated by changes in cerebral vasculature affecting both large and small vessels. 2 The microvascular disease results in chronic ischemic changes affecting the white matter, which in the long run can lead to cognitive alterations, which m...

Day-by-day variability of blood pressure and heart rate at home as a novel predictor of prognosis: the Ohasama study.
