Heart Health Can Help Predict Brain Health: Study

Poorer cardiac output correlates to lower brain volume, study finds

(HealthDay News on BusinessWeek) — What’s good for the heart is probably also good for the brain, suggests new research.

People with the highest cardiac output for their body size (cardiac index), meaning those with the greatest blood flow from their heart, tended to have more brain volume, which generally indicates a healthier brain.

In fact, the researchers said that people with the lowest cardiac output showed nearly two more years of brain aging than did those with the highest cardiac output.

What’s more, this connection held true even in people who had no known heart disease.

“Those with the lowest cardiac index and the middle group both had smaller brain volumes than those with the highest cardiac index,” said the study’s lead author, Angela Jefferson, an associate professor of neurology at the Alzheimer’s Disease Center at Boston University School of Medicine.

“Our results definitely suggest that cardiac health is related to brain health,” she noted.
