TUESDAY, May 27 (HealthDay News) -- Improved prediction of a person's heart attack risk can be achieved using calcium coverage scoring, which takes into account not only the amount, but also the distribution, of calcified plaque build-up in the coronary arteries, new research shows.

"Now we know that the location of the calcium in the arteries is particularly important in estimating a patient's potential risk," lead author Elizabeth Brown, a research assistant professor in the department of biostatistics at the University of Washington in Seattle, said in a prepared statement.
