Cardiac CT Scan


Who May Benefit From A Cardiac CT Scan?

  • A person who has a critical need to know if has a cardiac problem or not, for example, an airline pilot.
  • A person who has had bypass surgery or devices called stents put in to keep a coronary artery open and has subsequently developed symptoms but is getting inconclusive results from other tests.
  • A person with a low-risk profile but whose stress test result shows problems.
  • A person with unexplained chest pain.
  • A person why may have heart defects from birth.

Who Shouldn't Have The Scan?

  • Patients with very high heart rates who cannot take beta blockers - a type of medication that slows the rate at which the heart beats.
  • Persons with very irregular heartbeat as this disrupts image continuity.
  • Patients with kidney problems as they may be vulnerable to adverse effects from the contrast dye.
  • Patients who are unable to hold their breath for five to 10 seconds - the time needed for an image.
  • Pregnant women because of the radiation risk for the unborn child.

Heart Disease

The heart is a hollow, four-chambered, muscular organ that performs the major function of the cardiovascular system: pumping blood to all of the tissues of the body. Every tissue in the body depends on the proper functioning of the heart. Disease or injury to this major organ can greatly affect the function of the body system. Cardiovascular, or heart disease takes many forms.

Some forms cause a few nuisance problems, but many cause lifestyle changes. Some people are born with heart disease, but many develop it later in life. Eighty percent of all heart attacks stem from cardiovascular diseases, primarily coronary arteries that are diseased. Other common causes of heart failure include cardiomyopathy, hypertension, and valvular heart disease.

During the twentieth century great advances have been made in developing effective treatments for heart disease. Medications, devices, and surgical procedures have been developed which are capable of prolonging life, reducing symptoms, and eliminating the causes of many disease processes. There is still much progress to be made and development continues.
