Isolated thigh pain in myocardial infarction

Abstract

The referred pain of angina to upper half of the body is well known. However, isolated pain in the thigh as a presenting symptom in myocardial infarction is neither considered nor discussed at all. Here, we report a middle-aged man without demonstrable risk factors who presented to the emergency department for isolated bilateral anteromedial thigh pain. He was diagnosed with acute inferior wall myocardial infarction. After thrombolysis, the thigh pain improved. The probable mechanism for this is attributable to radiation of pain via sensory cardiac fibers that is present in the lumbar sympathetic ganglia, which resulted in pain.
