Beside the well-known evidences of the additional cardiovascular risk linked to a chronic increase of the pressure values, it is also likely that their variability may play a role as a risk factor. The blood pressure variability (BPV) is usually estimated using the Standard Deviation (SD) from the mean; our study allowed to elaborate a new method to assess the BPV as the average of the absolute difference between subsequent blood pressure measures; this method of calculating BPV was applied to the BP values measured routinely with standard ambulatory blood pressure monitoring (ABPM).
