The amount of blood pumped out of the heart is in co-relation with the ageing of the brain and brain health, say researchers.
This fact can be justified saying that if the heart happened to pump less blood then obviously the amount of blood reaching the brain too would be altered. If the brain failed to get the required amount of oxygen and nutrients, it would certainly affect the brain cells.
The study involving 1,500 people were not sick people, she asserted. The study, done to find out a link between younger people in their 30s with no heart disease and elderly people with disease, established that the brains tend to shrink with age.
"Whether lower cardiac index leads to reduced brain volumes and accelerates neurodegeneration on an eventual path to dementia is not yet clear", says Dr Clinton Wright.
So in other words, what's good for the heart is also good for the brain. The cardiac output, which is the flow of blood from the heart, is linked with the brain volume. That means greater the blood flow, more will be the volume of the brain, which of course means a healthy brain.
People with low cardiac index too had had smaller brain volumes. Cardiac index is the amount of cardiac output for a particular body size.
Lead researcher Dr Angela Jefferson, however, says that it isn't yet confirmed and requires an in-depth study.
