What measurement is classified as stage 1 high blood pressure?

The classification of blood pressure measurements is based on guidelines that categorize different ranges into stages of hypertension. Stage 1 high blood pressure is defined as having systolic blood pressure (the top number) ranging from 130 mmHg to 139 mmHg, or diastolic blood pressure (the bottom number) between 80 mmHg and 89 mmHg.

The measurement 140/90 mmHg represents stage 1 high blood pressure because it falls into the category where the systolic value is at the threshold of 140 mmHg, indicating hypertension, and the diastolic value is also at the threshold of 90 mmHg. This classification is crucial because it helps healthcare professionals identify individuals who may be at increased risk for cardiovascular events and other health complications.

In contrast, the other measurements do not meet the criteria for stage 1 hypertension. For instance, a reading of 130/80 mmHg is on the cusp and can be considered elevated but does not qualify as high blood pressure yet. Measurements like 150/100 mmHg would typically fall into stage 2 hypertension, indicating a more severe condition, while 120/70 mmHg is within the normal range and does not indicate high blood pressure at all.
