Elevations in Systolic Vs. Diastolic Blood Pressure
Blood pressure is measured as two numbers. The top number is referred to as systolic pressure, while the bottom number is referred to as diastolic pressure. Elevations in either number can indicate high blood pressure.

Systolic Pressure
-
Systolic pressure measures the pressure in the arteries when the heart beats. Ideally, this number should be less than 120. Stage 1 hypertension is diagnosed if this number is 140 or greater, and stage 2 hypertension is diagnosed if it is 160 or more. If systolic pressure is higher than 180, it is a medical emergency.
Diastolic Pressure
-
Diastolic pressure measures the pressure in the arteries between heartbeats. Normal diastolic pressure is less than 80. Stage 1 hypertension is diagnosed if this number is 90 to 99, and stage 2 is diagnosed if it is 100 or more. Emergency care is needed if diastolic pressure is higher than 110.

Which is More Important?
-
Elevated systolic pressure is considered a major risk factor for cardiovascular disease for people older than 50. Before the age of 50, diastolic hypertension is more prominent.
Your Blood Pressure Reading
-
A single high blood pressure reading does not necessarily mean you have high blood pressure. But if your systolic reading stays at more than 140 or your diastolic reading regularly reads more than 90, your doctor will most likely recommend lifestyle changes and/or prescription medication.
Prevention/Solution
-
Lifestyle changes include becoming more active, maintaining a normal weight, managing stress and eating a heart-healthy diet. If your blood pressure is 140/90, your doctor will probably prescribe medication.
