An increased 24-h blood pressure variability, expressed as SD of 24-h average ambulatory blood pressure values, is associated with target organ damage and cardiovascular risk in hypertension, while a physiological nocturnal blood pressure fall has been associated with reduced cardiovascular risk. Nocturnal blood pressure fall, however, may contribute markedly to the overall blood pressure variability. The aim of our study was to quantitatively assess the contribution of nocturnal blood pressure fall to 24-h blood pressure variability, and to propose a new method for computing 24-h blood pressure variability correcting for nocturnal blood pressure fall. From a large database of ambulatory blood pressure recordings obtained in two hypertension centres (Milan, Italy and Krakow, Poland), we selected 1995 recordings of a sufficiently high quality (
