【 摘 要 】

Angina pectoris is characterized by an oppressive pain in the chest due to inadequate blood flow to theheart muscle. If patients with chronic angina are refractory to conservative therapies and cannot undergocoronary revascularization surgery, spinal cord stimulation can be proposed as a possible treatmentoption. We present a case of a 70 years old female patient, who presented with angina pectoris at rest,which could not be relieved although surgical revascularization and cardiac stenting were performedpreviously. Angiography was performed but no lesions were found to require the repetition of surgery orcardiac stenting. She could only walk up to 20 meters despite maximum medical therapies. During sleep,chest pain woke her up. An eight-contact paddle electrode was placed with its cephalad tip at the T1–T4level on the left of the midline followed by test stimulations. The test stimulations should extend overthe areas that are painful during angina attacks. The symptoms of the patient improved remarkably in 24hours. His nitrate consumption could be reduced by 80% by the end of 3 months. If all available medicaland invasive treatment options fail, SCS can be used as a viable alternative for treatment.
