What's Your Coronary Calcium Score?
A screening modality for detecting heart disease.
Source: American Heart Association

The primary cause of heart disease is the build-up of plaque (atherosclerosis) in the arteries of the heart. This build-up, which consists of a combination of fatty material, fibrous material and calcified plaque, can cause the arteries to narrow. Plaque can also break away from the artery walls and cause a blockage. In both instances the heart muscle does not receive enough blood flow and oxygen - thus a heart attack can occur.

Using CT imaging with sub-second scanning capability, the equipment takes 70-90 images of your heart and coronary arteries without any injections, needles or removal of your clothing. The amount of calcified plaque detected in your coronary arteries is used to establish your coronary calcium score.
The scan itself takes about 10 minutes but you should plan on being there for 45-60 minutes, accounting for registration time, patient evaluation and instructions. First, you complete a brief risk factor questionnaire. Next, you lie down on the imaging table while a CT technologist places a few EKG leads on you. You are then asked to hold your breath while the images are taken. That's it. You can return to your regular routine. A board certified radiologist, using high tech software, calculates your cardiac score based on the images taken. He or she provides an evaluation of the results within 48 hours.

The radiation exposure during cardiac scoring is very minimal (comparable to the radiation received during a chest x-ray). No intravenous injections or needles are required. Not only is it safe, it is also simple. In most cases (unless there are certain types of buttons or bra metal involved), patients may keep their shirt or blouse on during the procedure.
Subtle early warning signs of heart disease can be detected. Cardiac scoring is the latest diagnostic tool to detect calcified plaque in the coronary arteries. The score, based on age, gender and other risk factors, is a strong indicator of your risk for coronary artery disease. With this information, your doctor can recommend the appropriate treatment, including diet and lifestyle changes, medication and/or further testing.
Yes, the plaque build-up process can be slowed, stabilized and reversed, in some cases, through aggressive lifestyle modification and/or through medication therapies under the guidance of your physician.

Loma Linda University Medical Center provides a comprehensive report, which includes the findings from your CT and the normal amounts of calcium found in men and women of differing ages. Also included in the report is the risk level that your score places you at and the current recommendations for treatment.
A formal report will be mailed to you and your designated physician in two to three days. If you do not have a physician, we can arrange for a referral to a Loma Linda University physician.
Payment is due in full at the time of your appointment. Most insurance carriers do not cover this test. If you wish to submit a claim to your insurance carrier, we will provide you with the necessary documentation.
No. You can choose to have the study on your own. If your physician has requested this test, please bring the written order with you at the time of your appointment.
Our scheduling desk is open from 8:00 a.m. to 5:00 p.m. Monday through Friday. If you would like to schedule an appointment for an outpatient scan, please call (909) 558-4407 or (909) 558-6113.
The examination will take place at Loma Linda University Medical Center Professional Plaza, Room 103B, 25455 Barton Road, Loma Linda, California.
Loma Linda University Medical Center was recently named a TOP 50 cardiac hospital in the nation, and is the first hospital in the area to offer cardiac MRI and 64 slice CT imaging services. As a hospital-based program you can be assured of receiving the quality of care that has been a tradition for more than 100 years.
For the most current, comprehensive discussion of this screening test and its implications, there are several web sites related to cardiac imaging that discuss this topic. Listed below are a few medical journal articles that have recently evaluated this test:

The National Heart, Lung, and Blood Institute (NHLBI) launched the National Cholesterol Education Program (NCEP) in November 1985. The goal of the NCEP is to contribute to reducing illness and death from coronary heart disease (CHD) in the United States by reducing the percent of Americans with high blood cholesterol.
