Hibernating myocardium caused by isolated, radiation induced left main stem coronary artery stenosis

摘要

A 45 year old man presented with a five week history of worsening exertional dys- pnoea and orthopnoea. He had also noted mild, bilateral ankle swelling. The patient had been diagnosed with stage III Hodg- kin's lymphoma in 1968 at the age of 21. During the same year he underwent total Nodal irradiation followed by chemo- Therapy in 1971. He had remained entirely Asymptomatic over the course of the next 24 years with no evidence of relapse. Car- diac catheterisation undertaken soon after admission revealed a tight left main stem stenosis with a left dominant system.
