The participants in the middle cardiac index group, who had low but still normal levels of blood pumping from the heart, also showed almost two years more brain aging than the people with the highest (or healthiest) cardiac index.
It may reveal unusually high ostia, an overriding Thebesian valve, an early bifurcation, or separate ostium of the middle cardiac vein.
