Coronary slow flow phenomenon caused by contrast-induced microvascular spasm.
Coronary slow flow phenomenon is not an infrequent finding and is often associated with chest pain, but the mechanism has not been fully elucidated. We report a case of coronary slow flow phenomenon induced after contrast injection which was resolved by nicorandil administration. Therefore, the microvascular spasm might be an important factor in coronary slow flow phenomenon and contrast medium can be a trigger.
