Emory University researchers stated that there is a scan that can find out the presence of calcified deposits in coronary arteries and further to know the life expectancy of a person.

The test is known as the coronary calcium or coronary artery calcification scan (CAC) and considered to be quite effective. Study's lead researcher Leslee Shaw said the team took the help of data from a free scan program organized by a Nashville outpatient clinic.

In the study, at least 9,500 men and women were involved. Their risk factors and results of scan of three years starting from 1996 were considered. The researchers said the participants did not show major symptoms of coronary heart disease. But on the basis of assessment of the information, the researchers were able to know the likelihood of deaths with the next 15 years.

For now, it's not clear whether the screening test will be used normally. However, the researchers think its use can significantly help in better outcomes of coronary heart disease. As per the Centers for Disease Control and Prevention, heart disease is the number one reason of death in America.

Out of 610,000 people who die of heart disease, around 365,000 deaths take place due to coronary heart disease. The study researchers said people having high calcium scores should adopt healthier lifestyles so that they live longer and healthier life.
