Final answer:
The American Heart Association updated the definition of hypertension in 2017 to a blood pressure of = or >130/80 mmHg from the previous = or >140/90 mmHg.
Step-by-step explanation:
In 2017, the American Heart Association changed the definition of hypertension from a blood pressure of = or >140/90 mmHg to a blood pressure of = or >130/80 mmHg. This update reflects a shift towards recognizing the health risks associated with lower blood pressure levels than previously considered as hypertensive.
With this change, more individuals may be diagnosed with hypertension, emphasizing the need for awareness and management to prevent serious complications such as heart attack or stroke. Hypertension is a condition of chronically elevated blood pressure, and it's often a silent disorder, which can lead to severe health issues if left untreated.
