At what blood pressure range is Stage 1 hypertension diagnosed?

Stage 1 hypertension is diagnosed when an individual's blood pressure readings fall within the range of 140-159 mmHg for systolic pressure and 90-99 mmHg for diastolic pressure. This classification is based on guidelines established by organizations such as the American College of Cardiology and the American Heart Association.

Understanding the significance of these numbers is crucial. A systolic reading of 140-159 indicates that the pressure in the arteries when the heart beats is elevated, while a diastolic reading of 90-99 reflects increased pressure in the arteries when the heart is at rest between beats. This stage indicates a greater risk for cardiovascular events and is a critical level for initiating lifestyle changes and potential medical interventions.

By contrast, the other ranges provided do not meet the criteria for Stage 1 hypertension as defined in recent clinical guidelines, making them incorrect for this specific diagnosis. The accurate identification of blood pressure levels is essential for effective management and prevention of complications associated with hypertension in older adults.
