What defines hypertension based on blood pressure readings?

Hypertension is defined as a condition where blood pressure readings are consistently elevated. According to the most current guidelines from the American College of Cardiology (ACC) and the American Heart Association (AHA), hypertension is diagnosed when blood pressure readings are consistently at or above 130/80 mm Hg. However, the specific thresholds relevant to the definition of hypertension may vary slightly depending on the source and the population being considered.

The choice stating blood pressure above 140/90 mm Hg reflects a target that was previously recognized and is still used in some contexts, particularly among certain populations and clinical practices. This level can often signify a stage of hypertension that necessitates treatment to reduce cardiovascular risk. However, current guidelines emphasize the threshold of 130/80 mm Hg, categorizing blood pressure levels into stages to guide management and treatment.

In light of this, while the answer provided may correlate with outdated perspectives, it is important to recognize that the contemporary understanding classifies hypertension at a lower threshold. The increased recognition of risks associated with lower blood pressure levels has shaped updated definitions and treatment approaches.
