Even, though actuarial science is my specialized area, medical research is one of my interest areas which I think would have profound blessing in the life of others and is essential for all actuaries. The hypothesis (Billian Conditional Flow Equation) is a description of how perfusion pressure (p), radius(r), length (L), and viscosity (ή) that happened in heart valve right before a heart attack.

In fact, the hypothesis clearly shows the effective influence of vessel radius on resistance and flow and can be served as an important concept to know how vascular stenosis and vascular tone change in vessel radius affect pressure, flow and how increase(or decrease) in heart valve orifice size affect flow and change in pressure across heart valves.

F=Pr⁴/2ήL

P=2P₀

Therefore, the final perfusion is twice the initial perfusion pressure and each has the same radius. Even though the above discussion is directed toward blood vessels, the factor that determined resistance across a heart valve are the same as described above, is only when length becomes insignificant because, path of blood flow across a valve is short compared to blood vessel.

PRACTICAL

1) The value P, determines the perfusion pressure that happens right before a heart attack.

2) The total equation above helps medical doctors to asses the flow in patient heart valves. If the radius is small and the flow states and perfusion pressure is high: then patient is likely to get heart attack. If the flow states and the perfusion pressure is low and the radius is large: then the patient is less likely to get heart attack
