Which blood pressure reading is classified as stage 1 hypertension?

The correct classification of stage 1 hypertension is based on the guidelines provided by organizations such as the American College of Cardiology and the American Heart Association. According to these guidelines, stage 1 hypertension is defined as having a systolic blood pressure (top number) between 130 to 139 mmHg or a diastolic blood pressure (bottom number) between 80 to 89 mmHg.

In this context, the reading of 140/90 mmHg falls directly into the category of stage 1 hypertension, as it shows a systolic value of 140 mmHg, which exceeds the threshold for stage 1. This classification is essential for determining appropriate management and treatment strategies for individuals with elevated blood pressure.

The other readings provided do not align with the definition of stage 1 hypertension. For example, a reading of 130/80 mmHg is classified as elevated blood pressure rather than stage 1 hypertension. Similarly, higher readings like 150/100 mmHg and 160/110 mmHg fall into the category of stage 2 hypertension, indicating a more severe categorization of the condition and often requiring more aggressive management.
