CAC test can identify diabetes patients at high risk of fatal cardiovascular disease

People with Type 2 diabetes have two to four times the risk of cardiovascular disease compared to people without the disease. The best way for doctors to predict which diabetes patients are at the greatest risk for heart disease is to use a coronary artery calcium (CAC) test in addition to the most commonly used assessment tool, according to researchers at Wake Forest Baptist Medical Center.

Current medical guidelines recommend treating all diabetes patients as high risk, but the Wake Forest Baptist study found that CAC can identify diabetes patients who are at very high risk for developing potentially fatal cardiovascular disease, as well as those who are at low risk.

"Our observations challenge accepted medical knowledge that all people with diabetes have the same risk. CAC is key in predicting the specific risk level," said Donald Bowden, Ph.D., professor of biochemistry at Wake Forest Baptist and senior author of the study, which is published online in the December issue of the journal Diabetes Care.

"People at very high risk are 11 times more likely to die from cardiovascular diseases as compared to those at low risk. Diagnosing a more precise risk level should help doctors provide more effective treatments and hopefully improve outcomes," he said.
