Awake systolic blood pressure variability correlates with target-organ damage in hypertensive
subjects. Commentary … Author keyword blood pressure variability hypertension …

Growing evidence associates blood pressure (BP) variability with cardiovascular events in
hypertensive patients. Here we tested the existence of a relationship between awake BP
variability and target-organ damage in subjects referred for suspected hypertension. Systolic
and diastolic BP variability were assessed as the standard deviation of the mean out of 24-
hour, awake and asleep BP recordings in 180 untreated subjects, referred for suspected
hypertension. Measurements were done at 15-minute intervals during daytime and 30 …
