Stenotic Lesions of the Intracranial Arteries in Relation to the Average Level and Variability of the Home Blood Pressure: A Cross-Sectional Study.

ABSTRACT:

Background

This study assessed the presence of intracranial arterial stenosis (ICAS) in relation to home systolic blood pressure (SBP) and its variability (BPV).

Methods

In 1510 untreated patients, ICAS was assessed by transcranial Doppler ultrasonography. SBP and BPV were determined from individual home BP recordings over seven days with triplicate readings in the morning and evening. BP variability was expressed as standard deviation (SD), coefficient of variation (CV), variability independent of the mean (VIM), and average real variability (ARV). CV was SD divided by the mean, VIM was SD divided by the mean to the power x  and multiplied by the population mean to the power x, and ARV reflected the average absolute difference between consecutive BP readings.
