Simple Heart Test For Babies Could Save Lives, Experts Say

A simple screening test could pinpointbabies who are at risk for heart defectsand potentially save their lives, according to a new study.

The test -- called a pulse oximetry test -- consists of sensors placed on a baby's hand and foot to check the baby's blood oxygen level. If it's too low, a heart ultrasound is conducted to detect any congenital (present at birth) heart defects.

Fifty percent of babies with congenital heart defects are identified during pregnancy, but that percentage could go up to 92 percent if this blood oxygen test was utilized,BBC News reported.

The "test is simple, painless and quite cheap -- picks up warning signs even in babies that seem healthy," study researcher Dr. Andrew Ewer, M.D., told BBC News. it can also pick up other health problems, like infections and breathing problems.

Congenital heart defectsare extremely common, affecting 1 in 100 babies in the United States. Most cases are treated with good results, with surgery, catheterization and/or medication, according to KidsHealth.org.

In the new study, conducted by British researchers at Birmingham University and Birmingham Women's Hospital and published in the journalThe Lancet, more than 20,000 babies who seemed healthy at birth took thepulse oximetry testbetween February 2008 and January 2009.
