Know Your Heart (FAQ's)

 
 

 
Coronary artery disease is the single largest cause of morbidity amongst all diseases so much so that it has been classified as having reached pandemic proportions by none less than the WHO (World Health Organisation). An increasingly sedentary lifestyle, changing food habits and a stressful and competitive lifestyle and work culture have multiplied the risk factors for coronary artery disease. The need of the times is a non invasive and outpatient investigation that accurately diagnoses coronary artery disease. CT coronary angiography plays this role to perfection

What is CT coronary angiogram?

A simple non invasive method to evaluate the status of the coronary vessels that supply the heart using an ultra fast 64 slice per rotation Multislice CT scanner.

How is CT coronary angiogram done?

The patient is put comfortably on a CT scanner table and a baseline calcium score is calculated in a matter of seconds. Following this contrast is injected in one of the peripheral veins with online ECG monitoring. All the images required for a CT coronary angiogram are obtained in one single breath hold within 5 seconds. Subsequently processed, reformatted, analyzed and evaluated on a workstation. The inferences deduced provide the radiologist an accurate picture of the heart and the coronary vessels that supply it. The arteries are evaluated for narrowing, blockage, presence of different varities of plaque ( stable/ unstable.. the rupture of which is a common cause of sudden death). Plaque evaluation also helps in deciding various modes of therapy. The status of the various chambers of the heart, cardiac muscle, and the main vessels carrying blood to and from the heart can also be easily seen. It is an excellent investigation to evaluate post operative grafts, stents, and to exclude non cardiac causes of chest pain.

Who should undergo a CT coronary angiography?

All patients with high risk factors are potential candidates.

What are the risk factors?

Patients having a strong family history of heart disease, diabetics, heavy smokers, high blood pressure, obesity, high cholesterol/ triglycerides, alcoholics, and those in high stress and tension jobs.

Are angiographies or studies of other organs possible on this machine?

Absolutely! A coronary angiogram is technically the most demanding study on a CT scanner. Compared to this  all other studies are literally a piece of cake. This machine performs all functions that any other CT scanner does with much more speed and accuracy.

Any other features?

  • Virtual colonoscopy ( study of the large intestine ) without inserting scopes.
  • Dentascan for accurate and correct placements of dental implants.

Advanced lung analysis for evaluation of lung nodules and parenchyma.
Very useful in follow up of cancer patients.
