The recommended classification is unchanged from the 2003 and 2007 ESH/ESC guidelines. Hypertension is defined as values >/=140 mmHg systolic blood pressure (SBP) and/or >/=90 mmHg diastolic blood pressure (DBP), based on the evidence from randomized controlled trials (RCTs) that in patients with these blood pressure (BP) values treatment-induced BP reductions are beneficial.
In addition to the prediction of cardiovascular risk, ambulatory blood-pressure monitoring, when used in conjunction with clinic blood-pressure assessments, is of potential value in a variety of other clinical conditions. Some of these conditions are:
A. At least 10 episodes occurring on <1 day/month on average (<12 days/year) and fulfilling criteria B-D
B. Headache lasting from 30 minutes to 7 days
C. Headache has at least 2 of the following characteristics:
