The elusiveness of population-wide high blood pressure control.

High blood pressure (hypertension) is a leading risk factor for cardiovascular disease. It is highly prevalent in the US general population, especially in those who are old, African American, or socially disadvantaged. Prevalence is also high and increasing worldwide. Awareness, treatment, and control of hypertension have improved over time, but there is still considerable room for improvement. The optimal solution to this health challenge varies by country. Several nonpharmacologic and pharmacologic interventions are well proven as effective means to prevent hypertension and improve control rates in those with established hypertension. Better prevention and control of hypertension will yield substantial general population health benefits and remain high priorities in public health.
