What Is a Healthy Calcium Score for a Heart?


Quick Answer

A normal coronary calcium score is under 100, and the closer the score is to zero, the less likely the chance that the patient has heart disease, according to WebMD. A score of 100 or more indicates that the patient likely has heart disease, and the higher the score, the greater the chance that heart disease is present. An elevated score indicates a greater likelihood of experiencing a heart attack within three-to-five years.

Coronary calcium scans make use of computed tomography technology to look for the presence of calcium in plaque buildup on the walls of the coronary arteries, explains WebMD. The test is useful in determining the presence of heart disease in its earliest stages and can also indicate the severity of the disease. The scan looks for calcium, which is not normally present in the arteries and is an indicator of coronary artery disease.

During the coronary calcium scan, a CT scanner takes images of the heart in small sections, recording them on a computer, notes WebMD. The patient lies on a table during the test, and a machine moves around the patient’s body, taking the pictures. Smoking, caffeine use and fast heart rates affect the results of the test.
