There is no good evidence to support routine fasting before angiography – the risk of vomiting leading to aspiration during angiography in a conscious, normally sentient patient is very small. Actual this method for monitoring the condition of blood vessels after operations on the brain or heart. Ultimately, the individual clinical situation will help make the decision for or against coronary CTA; and many issues--such as the patient's heart rate, body weight, or ability to perform a breath-hold, as well as contraindications to contrast or problems with vascular access (which may make invasive angiography more prone to complication)--will play a role in the decision-making process.
