Answer to Question 1
Optimal blood pressure
A reading of below 120 over 80 millimeters of mercury is considered optimal for adults 18 years and older.
Prehypertension
Measurements between 120 over 80 and 139 over 89 are classified as prehypertension. Individuals with prehypertension are at increased risk for progression to hypertension and are encouraged to make lifestyle changes to prevent hypertension.
Individuals in the 130 over 80 to 139 over 89 range are at twice the risk to develop hypertension as those with lower values.
High blood pressure
Beyond those levels (systolic over 140 or diastolic over 90), the risks of heart attacks and strokes rise in direct proportion to increasing blood pressure.
