Q: Postprandial angina is usually associated with severe coronary vessel disease?
Postprandial chest pain is in general of gastrointestinal origin. If associated with coronary origin, it can be an alarming situation. It signifies possible left main or multi-vessel coronary disease. For reason not entirely clear, it usually occurs after dinner.
Also, it may occur postprandially at rest making diagnosis even harder.
