Cycling cadence to match heart rate?

Crazy cycling thought of the day:

There’s been a lot of research on how your cadence affects your heart rate–for a given power output, there is usually a cadence that creates the lowest heart rate for an individual.

But could there be a correlation the other way? What if your blood flow worked best when pumping at a similar frequency to your pedaling? It seems to make sense that oxygen would best be replenished at the same frequency it was depleted.

Given a bicycle with infinitely-variable transmission, might you find good results by matching your cadence to something like 1/2 your heart rate, e.g. 90 rpm for a heart rate of 180?
