Fasting is recommended for more than 4 hours before the coronary CTA test, but there are no special dietary requirements, so you can eat pork dumplings 4 hours before the coronary CTA test.
Coronary CTA involves injecting a contrast agent into a vein, part of which travels with the blood flow to the coronary arteries. Multi-layer scanning is performed by CT, followed by three-dimensional reconstruction using computer software, which shows the shape and structure of the coronary arteries, and determines whether the coronary arteries are stenotic as well as the location and extent of the stenosis. Since coronary angiography requires fasting for more than 4 hours, you can eat pork dumplings before that.
Vital signs and electrocardiogram need to be monitored before coronary CTA, and an iodine allergy test should be performed to avoid allergic reactions. It is also important to avoid excessive activity and to stabilize the heart rate to less than 70 beats per minute before the test.
Patients are advised to consult their doctors before the examination to avoid inconvenience.
