Spinal cord stimulation (SCS) effectively manages refractory angina by reducing myocardial ischemia and improving blood flow. This safe treatment offers pain relief and enhances patients' quality of life.

Area of Science:

  • Cardiology
  • Neurology
  • Medical Devices

Background:

  • Refractory angina pectoris poses challenges for patients unsuitable for revascularization.
  • Spinal cord stimulation (SCS) is an established therapy for managing chronic pain conditions.

Purpose of the Study:

  • To evaluate the efficacy and safety of SCS in patients with refractory angina.
  • To investigate the impact of SCS on myocardial ischemia and related symptoms.

Main Methods:

  • Utilized exercise testing, ambulatory electrocardiogram (ECG), and coronary sinus blood lactate measurements.
  • Assessed patient-reported outcomes including angina attack frequency and medication use.

Main Results:

  • SCS demonstrated a significant decrease in myocardial ischemia without masking symptoms.

  • Patients reported fewer angina attacks, reduced glyceryl trinitrate consumption, and improved quality of life.
  • Neurostimulation improved microcirculatory blood flow and increased the threshold for ischemia.

    • Conclusions:

    • Spinal cord stimulation is a safe and effective treatment for refractory angina.
    • SCS offers benefits beyond pain relief, including improved cardiac function and patient well-being.
    • Potential mechanisms include anti-nociceptive, anti-sympathetic, and hemodynamic effects.
