ObjectiveTo investigate the possibility that spinal cord stimulation (SCS) used for pain relief can conceal acute myocardial infarction (AMI).DesignProspective evaluation of patients treated with SCS.SettingUniversity hospital.Patients50 patients with coronary artery disease and severe, otherwise intractable angina treated with SCS for 1-57 months.Main Outcome MeasuresNecropsy findings, symptoms, serum enzyme concentrations, electrocardiographic changes.ResultsTen patients were considered to have had AMI. In nine of these SCS did not conceal precordial pain and in one patient no information about precordial pain could be obtained.ConclusionThere was no evidence that SCS concealed acute myocardial infarction.
