What indicates hypertension for diastolic blood pressure?

Diastolic blood pressure is the measurement of the pressure in the arteries when the heart is resting between beats. According to guidelines established by organizations such as the American College of Cardiology and the American Heart Association, a diastolic blood pressure reading of 90 mmHg or above indicates hypertension. This threshold is significant because it reflects an increased risk for cardiovascular diseases and other health issues associated with elevated blood pressure levels.

Having a diastolic measurement above this threshold suggests that the heart is experiencing increased resistance in the blood vessels, which can lead to various complications. Monitoring diastolic blood pressure is crucial in diagnosing and managing hypertension and related health risks. Lower thresholds, such as 80 or 70, do not meet the criteria for hypertension, as they are considered to be within the normal to elevated ranges instead. Thus, the only correct indicator of hypertension in this context is a diastolic blood pressure reading above 90 mmHg.
