How you prepare

When you schedule your appointment for a heart scan at a hospital or outpatient medical center, ask what special instructions you should follow, how early you should arrive, and what paperwork or identification you will need.

Food and medications

You may be asked to avoid caffeine and smoking for four hours before the test.

Clothing and personal items

When you arrive for the procedure, you will be asked to remove clothing above the waist and to wear a medical gown. You will also need to remove jewelry around your neck or near your chest. In order to make things easier for yourself, you can consider leaving jewelry at home and wearing clothes that are easy to change.
