What constitutes Stage 3 hypertension?

Stage 3 hypertension is characterized by extremely high blood pressure levels, specifically defined as having a systolic pressure of 180 mm Hg or higher and/or a diastolic pressure of 120 mm Hg or higher. This stage indicates a significant risk for cardiovascular events and requires immediate medical attention. The criteria for Stage 3 hypertension reflect a severe elevation in blood pressure that necessitates urgent intervention to prevent complications such as heart attack or stroke.

The other provided measurements fall into different categories of hypertension. For instance, the ranges indicated in the other options represent lower stages or classifications of hypertension—essentially showing steps leading up to Stage 3. Measurements below 180/120 do not meet the severe threshold necessary to be classified as Stage 3, making it crucial to correctly identify these critical levels for effective management and treatment of hypertension.
