Diastolic Or Systolic Blood Pressure! Which BP Reading Is More Important?

Diastolic blood pressure and systolic pressure are both vital, but do you know which one carries more risk? I’ll explain the science behind diastolic and systolic blood pressure and help you understand diastole and systole to identify what is a good blood pressure reading for your age.


When comparing diastole vs systole, many patients ask which blood pressure reading is more important for preventing a stroke or heart attack. As an Advanced Clinical Practitioner, I’ve seen how medical thinking has shifted from focusing on the bottom number to prioritizing the top number, especially for those over 50. In this video, we dive into landmark research like the SPRINT trial and the Framingham Heart Study to settle the debate once and for all.


We break down how stiffening arteries impact your systolic numbers and why a high diastolic reading means your vessels never truly get a chance to rest.


What you'll learn:

-The biological difference between the heart contracting (systole) and resting (diastole).

-Why systolic pressure is a stronger predictor of heart disease as we age.

-Insights from The Lancet and NEJM on how both numbers independently predict risk.

-What "isolated systolic hypertension" means for adults over 60.

-How to use the A&D Heart Track app to monitor your trends at home.
