Phaeochromocytoma with nocturnal elevation of blood pressure.
A 47-year-old woman with phaeochromocytoma showed blood pressure changes characterized by the regular appearance of hypertension at night. The urinary excretion of catecholamines and their metabolites showed augmentation roughly parallel with the elevation of the blood pressure. During normotensive periods, the urinary excretion of catecholamines and their metabolites was elevated. The findings...
متن کاملDaytime blood pressure elevation after nocturnal hypoxia.
The purpose of this study was to investigate whether nocturnal hypoxia causes daytime blood pressure (BP) elevation. We hypothesized that overnight exposure to hypoxia leads the next morning to elevation in BP that outlasts the hypoxia stimulus. We studied the effect on BP of two consecutive night exposures to hypobaric hypoxia in 10 healthy normotensive subjects. During the hypoxia nights, sub...
متن کاملNocturnal blood pressure monitored by ambulatory blood pressure measurement in elderly hypertensive patients.
This study was designed to characterize the nocturnal fall of blood pressure (NFBP) of elderly hypertensive patients (EH), with or without cerebrovascular disease or diabetes mellitus, as measured by automated blood pressure (BP) monitoring. Systolic and diastolic BP and heart rate was measured every 15 minutes in 133 hospitalized patients with nearly similar schedules and diets. The patients w...
متن کاملDipping comes of age: the importance of nocturnal blood pressure.
It is now just 21 years since the dipping phenomenon was described in a letter to The Lancet.1 In a cohort of 123 consecutive patients who had ambulatory blood pressure (BP) measurement (ABPM) performed, the majority (83%) were dippers on the basis of having a difference of 10/5 mm Hg between day and nighttime BPs, with 17% being nondippers. The nondippers had a significantly higher frequency o...
متن کاملNocturnal blood pressure dipping in acute ischemic stroke.
OBJECTIVES We aim to assess the impact of early nocturnal blood pressure (BP) variation in the functional outcome of patients after an acute ischemic stroke. MATERIALS AND METHODS We included consecutive stroke patients treated with intravenous thrombolysis (IVrtPA) in a tertiary stroke center. BP measurements were performed at regular intervals throughout day and night during the first 48 h ...
