Left ventricular outflow and mean aortal pressure?

Question

Obviously I wasn't specific enough in my question so will re-phrase it.
Is there any evidence from direct measurements of total flow and mean pressure at the aortic valve, that the quotient of pressure over flow increases with the aging process?

Answer 2

Yes. Go to pubMed or any scientific/medical journal and do a search with this question....Being in the medical field I can answer this in very lamens terms....As one ages, their arterial vessels as well as ventricles and atria become atherosclerotic or "hardened" by plaque residues....This decreases flow which leads to cardiovascular disease (because of an increased blockage creating pressure against systemic flow).....Think about plumbing in your house...When it is first installed the piping works great....Inflow into the pipes = outflow....Over time, things get lodged down the drain and flow eventually becomes backedup....The flow through the drain decreases as the pressure/amount of water built up outside it increases.....When answering any medical question think of a similar situation in your day-to-day life....We model many products after our own body...

Answer 3

I understand the question but I don't undertsand why you are asking it.

In your answer to a previous question you stated that you are a cardiovascular physicist. Why are you asking this question when you should either know the answer or know where to get the answer?
