PHOENIX Genetics may hold the key to treating heart disease, according to a University of Arizona professor.

Scientists have identified genetic markers that can predict if a person is likely to be diagnosed with heart disease, which is the No. 1 killer for both men and women nationwide.

University of Arizona professorDr. Robert Roberts said since genetic markers do not change throughout a persons life, this new discovery is so far the most accurate method ofpredicting heart disease.

Whileheart disease has been proven to be preventable by decreasing conventional risk factors, such as quitting smoking,about 50 percent of heart disease risk is in a persons genes.

Scientists are developing a genetic test that can find these markers using either blood or saliva, Roberts said, adding in the next few years, they will be able to treat people without symptoms who have genetic risks.

Genetic testing will tell us if you are at risk, he said. If you are at risk [then] we can start treatment immediately.
