Hypertension can be classified as either primary (essential) or secondary.
The 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines define hypertension in adults as a blood pressure of ≥ 130/80 mm Hg and the Eighth Joint National Committee ( JNC 8) criteria specify ≥ 140/90 mm Hg.
Hypertension is a common condition that affects one in every three adults in the United States and is becoming increasingly prevalent among children.
