Coronary angiography revealed that the left circumflex artery （LCX） was acutely and totally occluded at the mid-portion. In addition, the proximal and mid-portion of the right coronary artery （RCA） had a 60% occlusion. We inferred that the LCX was the culprit artery and primary PCI was successfully performed. Six weeks later, the patient had an eventful course with recurrence of chest pain. Coronary angiography showed no significant ste- nosis in the previous LCX lesion, while the proximal and middle potion of the RCA had a 90% occlusion. Our case demonstrates the systemic nature of acute coronary syndromes and highlights the inherent instability of coronary artery disease.展开更多
