Which blood pressure reading is classified as hypertension?

A blood pressure reading classified as hypertension is generally defined as having a systolic value of 130 mmHg or greater, or a diastolic value of 80 mmHg or greater, based on the guidelines set by organizations such as the American College of Cardiology and the American Heart Association.

The reading of 140/90 falls clearly within the range designated as hypertension. Specifically, the systolic value of 140 mmHg exceeds the threshold for high blood pressure, and the diastolic value of 90 mmHg meets the criteria as well. Therefore, this reading indicates a state of hypertension which may require lifestyle changes or medical intervention to manage and prevent associated health risks, such as cardiovascular disease.

The other readings fall below the hypertension classification. For instance, a reading of 120/80 is considered ideal or normal. The reading of 130/85 indicates elevated blood pressure but does not yet meet the criteria for hypertension, which begins at 130/80. Lastly, a reading of 110/70 is well within the normal range. Thus, the classification of hypertension clearly aligns with the reading of 140/90.
