A blood pressure reading of 140/90 mmHg falls within the range that is classified as hypertension according to the American Heart Association's guidelines. 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 scenario, the systolic pressure is 140 mmHg, which clearly surpasses the upper limit of normal blood pressure. The diastolic pressure of 90 mmHg is also considered elevated. When both readings are elevated, the person is diagnosed with hypertension, which is a significant risk factor for cardiovascular diseases, including heart attack and stroke. Managing hypertension often involves lifestyle modifications and, in some cases, medication.

Understanding this classification is crucial for recognizing and managing blood pressure effectively in a healthcare setting, ensuring timely interventions and improving patient outcomes.
