According to stages of hypertension, which of the following blood pressure readings is considered elevated?

The classification of blood pressure readings is critical in understanding hypertension, and certain thresholds categorize blood pressure levels into different stages. The American Heart Association (AHA) designates normal, elevated, and hypertensive readings based on systolic and diastolic numbers.

In this context, a blood pressure reading of 128/78 mm Hg is considered elevated. Elevated blood pressure is specifically defined as a systolic reading between 120-129 mm Hg and a diastolic reading less than 80 mm Hg. Since 128 falls within the systolic range of elevated blood pressure and the diastolic number is under 80, it aligns perfectly with the criteria established for this condition.

By contrast, a reading of 120/80 mm Hg is classified as normal, while 140/90 mm Hg is categorized as stage 2 hypertension. Additionally, a blood pressure reading of 110/70 mm Hg falls within the normal range. Understanding these classifications is vital for identifying potential health risks and initiating appropriate lifestyle changes or interventions.
