Angiographic evidence of left main trunk spasm as a possible cause of syndrome X.
The present case is a 49-year-old female who began to feel a chest pain during exercise 2 years ago. Recently, the chest pain occurred during light exercise as well as at rest. The electrocardiogram during the attack showed remarkable ischemic ST segment depression. No abnormality was found in the coronary cineangiography. She was diagnosed as Syndrome X. However, coronary cineangiography during an attack on another day showed a severe spasm in the left main trunk. Thus, a spasm must be considered as one of the causes of "Syndrome X".
