Heart Scan & Calcium Scoring

The heart scan or calcium scoring examination can be performed in approximately 15 seconds. When receiving a heart scan, the radiation dose is as low as possible-comparable to only one third of the natural radiation received from our atmosphere.

A positive coronary calcium score result from your heart scan serves as a good indicator of the risk factors for certain types of heart attack. A negative calcium score from your heart scan is a good indicator that coronary vessels are intact.

Who should have a heart scan?

You belong to a high-risk group if any of the following factors apply to you:

  • You have a high cholesterol level
  • You have high triglyceride values
  • You smoke
  • You have high blood pressure
  • You have family history of heart disease
  • You have diabetes
  • Any of the following factors in combination with a sedentary lifestyle

If one or more of the above points apply to you, contact The Cardiac Center of Texas to find out more about heart scans and calcium scores and CT angiography for early diagnosis of heart disease.

What Does My Calcium Score Mean?

Doctors use calcium scores, along with conventional risk factors, to estimate your risk of heart disease. Here is an example based on a statistical model developed by Dr. Mark Pletcher at the University of California, San Francisco:

Consider a 60 year-old woman who doesn’t smoke and doesn’t have diabetes:

The factor that she has high blood pressure and high cholesterol puts her risk of suffering a heart attack or other cardiac event over the next 10 years at  If her calcium score is zero, her risk falls to If her calcium score is 1-100  If her calcium score is 101-400 her risk jumps to If her calcium score is over 400 her risk jumps to
15% 6-9% 13- 15%  25-31% 34-51%
