Early life stress may take early toll on heart function
Date:2/21/2013

AUGUSTA, Ga. Early life stress like that experienced by ill newborns appears to take an early toll of the heart, affecting its ability to relax and refill with oxygen-rich blood, researchers report.

Rat pups separated from their mothers a few hours each day, experienced a significant decrease in this basic heart function when as life tends to do an extra stressor was added to raise blood pressure, said Dr. Catalina Bazacliu, neonatologist at the Medical College of Georgia and Children's Hospital of Georgia at Georgia Regents University. Bazacliu worked under the mentorship of Dr. Jennifer Pollock, biochemist in the Section of Experimental Medicine in the MCG Department of Medicine.

The relaxation and filling rate remained low in the separation model, although decreases stabilized by ages two and six months, as the rats neared middle age. Both the model and controls experienced decreases in those functions that come naturally with age.

Interestingly, the force with which the heart ejected blood remained unchanged with the additional stressor, angiotensin II, a powerful constrictor of blood vessels. Echocardiography was used to evaluate heart function.

"We expected the heart's ability to relax and refill to lag behind in our model," said Bazacliu, whose research earned her a Young Investigator Award from the Southern Society for Pediatric Research. She is reporting her findings Feb. 22 during the Southern Regional Meetings in New Orleans, sponsored by the society as well as several other groups including the Southern Section of the American Federation for Medical Research.

"We believe these babies may be at increased risk for cardiovascular disease and we are working to understand exactly what puts them at risk," Bazacliu said. She believes hers is the first animal study of this aspect of heart function.
