Coronary stenting effectively managed severe coronary artery spasm in select patients refractory to medication. While restenosis occurred in some, stenting offered a valuable option when medical therapy fails for focal coronary artery spasm.

Area of Science:

  • Cardiology
  • Interventional Cardiology

Background:

  • Coronary artery spasm can cause severe symptoms and is typically managed with pharmacologic therapy.
  • Refractory cases pose a clinical challenge, necessitating evaluation of alternative treatment strategies.

Purpose of the Study:

  • To assess the efficacy and safety of coronary stenting in patients with severe coronary artery spasm unresponsive to aggressive medical management.

Main Methods:

  • A cohort of nine patients with severe, angiographically confirmed coronary artery spasm refractory to pharmacologic treatment underwent coronary stenting.
  • Outcomes including recurrent spasm, ischemia, and restenosis were monitored post-procedure.

Main Results:

  • No patients experienced recurrent spasm within the stent leading to hospitalization for unstable ischemia.

  • Therapeutic failure occurred in one patient due to persistent spasm or spasm in a different artery.
  • Restenosis was observed in three patients, requiring repeat revascularization.

    • Conclusions:

    • Coronary stenting can be an effective adjunct therapy for carefully selected patients with focal coronary artery spasm that is refractory to medical treatment.
    • Medical therapy remains the primary and standard initial approach for managing coronary artery spasm.
