CORONARY CALCIUM SCAN

Coronary artery disease occurs when plaque builds up and narrows the arteries that supply blood to your heart (atherosclerosis) and is the leading cause of heart attacks.

A Coronary Calcium Scan measures the amount of plaque or calcium in the walls of your coronary arteries. It provides a calcium score, which your cardiologist will use alongside other health information to determine your future risk of coronary artery disease or heart attack before you develop any symptoms.

You should consider having a coronary calcium scan if:

  • you are a man over 45 years of age
  • you are a woman over 55 years of age
  • you have at least one of the following risk factors
    • family history of heart disease
    • high cholesterol
    • high blood pressure
    • diabetes
    • smoker

The procedure takes about 5 minutes, involves no injections and does not require you to fast beforehand.

CORONARY COMPUTED TOMOGRAPHY (CTA)

A Coronary Calcium Scan measures the amount of plaque or calcium in the walls of your coronary arteries. It provides a calcium score, which your cardiologist will use alongside other health information to determine your future risk of coronary artery disease or heart attack before you develop any symptoms.

Coronary CTA provides pictures of the coronary arteries, which supply blood to the heart muscle, in a non-invasive manner. It enables your cardiologist to look for narrowings, some of which cannot be detected by the more traditional exercise testing, but which cause around three quarters of all heart attacks. Detecting these narrowings early is important as medications can be prescribed to prevent an impending heart attack. Based on the results from the CTA, your surgeon will order further tests to decide on any course of treatment.

We use the latest generation, state-of-the-art Toshiba 64-Slice Coronary CTA scanner, which can simultaneously acquire 64 image slices of the heart in one minute, resulting in highly detailed images of the coronary arteries and the heart. Learn more.
