Answer:
Systolic blood pressure
Explanation:
The contraction of the heart that allows blood to pump is the systole and the relaxation of heart after contraction is the diastole. These are the two phases of the cardiac cycle. The systolic blood pressure is more important than diastolic blood pressure as it provides the ideas of heart attack or stroke.
The increase in the systolic pressure and low or normal diastolic pressure is called ISH (Isolated Systolic Hypertension). This is an indication of high risk of heart attach or stoke. The diastolic pressure is sometimes important in detecting risk of heart attack in individual below the age of 40 years. The younger individuals are less prone to heart attack risks.
