Blood pressure variability: Epidemiological and clinical issues

Blood pressure variability: epidemiological and clinical issues.

Blood pressure variability (BPV) is a classical physiological phenomenon. This paper describes major epidemiological and clinical issues of BPV which may be important to understand the background of this interesting feature. In healthy subjects, BPV is a measure of hemodynamic condition and refl ects function of autonomic nervous system. BP fl uctuations result from the complex interaction betw...

Blood pressure variability: clarity for clinical practice.

Mechanisms and clinical implications of blood pressure variability.

Several studies have unequivocally shown that the target-organ damage associated with the hypertensive condition is more closely related to 24 h average blood pressure values than to clinic blood pressure. Blood pressure, however, is highly variable over the daytime and night-time period, and of major interest is whether average 24 h blood pressure values, as well as 24 h blood pressure variabi...

Blood pressure variability. Importance in research and in clinical hypertension.

mean value, but also 24h blood pressure variability seems to be independently related to the end organ damage of hypertension. This is illustrated in figure 1, which is taken from a study where 108 hypertensive patients underwent a 24h intra-arterial blood pressure monitoring in ambulatory conditions by Oxford technique 16. A score based on clinical and laboratory examinations was used to quant...

Stroke and blood pressure variability.

Sleep apnoea is associated with increased cardiovascular risk. Sleep apnoea is common after stroke and associated with increased blood pressure variability as described by Turkington and co-workers in this issue of Clinical Science. Both sleep apnoea and blood pressure variability confer a poor prognosis after stroke and are potentially treatable. Many studies of CPAP (continuous positive airwa...
