Primary hypertension
Alerts and Notices
Synopsis
Hypertension can be classified by stage (stage 1 and stage 2) and, when combined with atherosclerotic cardiovascular disease (ASCVD) risk, the stage can help determine treatment. Lifestyle changes are the cornerstone of therapy with pharmacologic intervention required in some patients to meet target blood pressure measurements.
Systolic and diastolic hypertension are independent risk factors for cardiovascular disease.
Blood pressure greater than 180/110-120 mm Hg can be a sign of acute severe hypertension and may require emergency therapy.
