Chest pain in cardiac syndrome X--caused by neuromuscular disorders?
We wanted to find out if chest pain in cardiac syndrome X can be a manifestation of neuromuscular disorders. Five patients with cardiac syndrome X (3 women, 2 men), aged 34 to 70 years, consented with a clinical neurological examination, muscle enzyme testing, electroneurography of the right median and peroneal nerves and electromyography of the right brachial biceps and anterior tibial muscles. A neuromuscular disorder was found in 1 of the 5 investigated patients. The 60-year-old man presented with a monoparesis of the left leg and sensory dysfunction of the left upper and lower limb. He was diagnosed as having either posttraumatic myelopathy or radiculopathy. Since chest pain in cardiac syndrome X can be caused by neuromuscular disorders, a comprehensive neurological examination is recommended in patients with this disorder.
