Figure 1: The figure illustrates the distribution (%) of blood pressure (BP) categories according to the 2007 ESH-ESC guidelines in men and women, respectively. The 2007 ESH-ESC blood pressure categories; normal optimal BP <120/80 mm Hg, normal BP <130/85 mm Hg, normal high BP <140/90 mm Hg. Hypertension was defined as known documented diagnosis for high blood pressure, or by three consecutive BP reading 140/90 mm Hg (systolic and/or diastolic). When the BP exceeded these limits only once or twice, the BP was categorised as unstable.
