Approximately 16.7 million individuals worldwide,1 including 850 000 in the United States,2 annually die of cardiovascular diseases. Almost 8 million of these deaths are attributed to hypertension (systolic blood pressure [SBP] ≥140 mm Hg and/or diastolic blood pressure [DBP] ≥90 mm Hg or taking antihypertensive medication).3 Many additional deaths are attributable to prehypertension (SBP ≥120-139 mm Hg and/or DBP ≥80-89 mm Hg). In the United States, more than 27% of adults have hypertension and another 31% have prehypertension.4 The lifetime probability of developing hypertension in the United States approaches 90%.5 Worldwide, more than 26% of adults have hypertension.6
