Prehypertension is defined by which blood pressure range?

Prehypertension is characterized by a systolic blood pressure of 120-139 mmHg or a diastolic blood pressure of 80-89 mmHg. This classification serves as an important warning sign that an individual may develop hypertension if lifestyle changes are not made. The definition helps healthcare providers identify patients who are at risk and can benefit from preventative measures, such as changes in diet, exercise, and monitoring blood pressure more closely.

In this context, the correct choice reflects the systolic range for prehypertension, which is crucial because systolic blood pressure is a significant indicator of cardiovascular risk. The thresholds set for prehypertension are pivotal in clinical practice as they guide healthcare providers in managing and reducing the risk of progression to hypertension and its associated complications.
