Coronary stenting demonstrated high technical success (98%) in treating angina. However, complications like stent occlusion, infarction, and death occurred in 13% of patients, highlighting risks associated with the procedure.

Area of Science:

  • Cardiovascular Medicine
  • Interventional Cardiology
  • Medical Device Technology

Background:

  • Coronary artery disease remains a leading cause of morbidity and mortality.
  • Percutaneous transluminal coronary angioplasty (PTCA) is a common intervention, but complications like acute occlusion and restenosis necessitate further treatment.
  • Coronary stenting has emerged as a crucial tool to address these challenges.

Purpose of the Study:

  • To evaluate the technical success and in-hospital complications of coronary stenting.
  • To assess the outcomes of both self-expanding and balloon-expandable stents in patients with severe angina.
  • To analyze the indications and procedural characteristics of coronary stenting in a real-world clinical setting.

Main Methods:

  • A retrospective analysis of 75 coronary stent implantations in 62 patients between April 1988 and December 1991.

  • Patients presented with New York Heart Association class II-IV angina, including those with prior coronary artery bypass grafting (CABG).
  • Stenting was performed for acute post-PTCA occlusion (bail-out) or restenosis (elective).

    • Main Results:

    • Technical success was achieved in 98% of stent implantations.
    • The primary indications were acute post-PTCA occlusion (73%) and restenosis (24%).
    • In-hospital complications included temporary stent occlusion (3%), permanent stent occlusion (8%), Q-wave infarction (8%), need for CABG (11%), and death (5%). At least one major complication occurred in 13% of patients.

    Conclusions:

    • Coronary stenting is a technically successful procedure for managing complex coronary artery disease and post-PTCA complications.
    • While effective, the procedure carries significant risks of major adverse cardiac events, including stent occlusion, myocardial infarction, and mortality.
    • Further research and technological advancements are warranted to improve stent safety and reduce complication rates.
