When it is done?

CT coronary angiography is done to provide useful information for the following patients :

• Anyone who have symptoms of atypical chest pain with an equivocal stress echocardiogram.
• Anyone who is at high risk for coronary artery disease based on known risk factors like –high blood pressure, diabetes, high cholesterol, family history of heart disease, smoker, sedentary life style, overweight by 20% or more, high stress lifestyle, men over age 40 or greater and women overage 50 years.
• Patients who are on cholesterol reducing medications, or who are on exercise and nutrition therapies. For these patients it is useful to follow the progression or regression of coronary artery disease & modify treatment accordingly.
• Patients who had coronary artery bypass surgery in the past – to evaluate patency of the graft for further follow ups.
• Can also be done to evaluate patency of coronary artery stents ( in selective types of stents)
