Which of the following blood pressure readings indicates hypertension?

A blood pressure reading of 140/90 is classified as hypertension according to the guidelines established by organizations such as the American Heart Association. Hypertension is generally defined as having a systolic pressure (the first number) of 130 mmHg or higher, or a diastolic pressure (the second number) of 80 mmHg or higher.

In this case, a reading of 140/90 falls within the range that indicates stage 1 hypertension, as it exceeds both the systolic threshold of 130 mmHg and the diastolic threshold of 80 mmHg. This classification is important, as managing hypertension is crucial to reduce the risk of cardiovascular diseases.

Other readings provided neither meet the systolic nor diastolic criteria for hypertension, indicating they are either within the normal range or at the threshold for elevated blood pressure, but not classified as hypertension themselves. Understanding these distinctions helps in assessing cardiovascular risk and the need for potential lifestyle modifications or medical interventions.
