Hypertension is defined as values >140 mmHg SBP and/or >90 mmHg DBP, based on the evidence from RCTs that in patients with these BP values treatment-induced BP reductions are beneficial (Table 1) . The same classification is used in young, middle-aged, and elderly subjects, whereas different criteria, based on percentiles, are adopted in children and teenagers for whom data from interventional trials are not available . JNC 7 introduced in 2003 the category of prehypertension, which is defined as SBP of 120 to 139 mmHg and DBP of 80 to 89 mmHg (Table 2) . Patients with prehypertension are at increased risk of developing hypertension, those with blood pressure values 130–139/80–89 mmHg have a two times greater risk of developing hypertension than those with lower values . Hypertension is a highly prevalent cardiovascular disease, which affects over 1 billion people worldwide . Although more than 70% of hypertensive patients are aware of the disease, only 23–49% are treated, and fewer (20%) achieving control [2, 4, 5]. Hypertension prevalence varies by age, race, education, and so forth.
