Summary

Multivessel coronary angioplasty shows comparable outcomes to single-vessel angioplasty in major complications and 5-year survival. However, multivessel procedures have a higher rate of repeat coronary angioplasty within the first year.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Clinical Outcomes Research

Background:

  • Coronary artery disease often involves multiple vessels, necessitating treatment strategies that address this complexity.
  • Multivessel coronary angioplasty aims to revascularize all significantly diseased coronary arteries in a single procedure.
  • The comparative efficacy and safety of multivessel versus single-vessel angioplasty require thorough investigation.

Purpose of the Study:

  • To compare the efficacy and safety of multivessel coronary angioplasty with single-vessel angioplasty.
  • To evaluate in-hospital complications, long-term survival, and event-free survival between the two treatment groups.
  • To identify specific outcomes that may differ between multivessel and single-vessel angioplasty.

Main Methods:

  • A retrospective comparison of 569 consecutive patients undergoing multivessel angioplasty against 569 age- and sex-matched controls undergoing single-vessel angioplasty.
  • Analysis of baseline characteristics, including left ventricular function and number of diseased vessels.
  • Assessment of major in-hospital complications (death, myocardial infarction, bypass surgery) and 5-year actuarial survival rates.

Main Results:

  • In-hospital complication rates for death, Q wave myocardial infarction, and emergency bypass surgery were similar between multivessel and single-vessel angioplasty groups.
  • Five-year actuarial survival rates were comparable: 93% for multivessel angioplasty and 92% for single-vessel angioplasty.
  • Event-free survival was similar, with the exception of an 8% higher incidence of repeat coronary angioplasty in the first year for patients who underwent multivessel angioplasty (p = 0.03).

Conclusions:

  • Multivessel coronary angioplasty is a safe and effective treatment option with outcomes comparable to single-vessel angioplasty regarding major complications and long-term survival.
  • The primary difference observed is a higher need for repeat coronary angioplasty in the first year following multivessel procedures.
  • These findings support multivessel angioplasty as a viable strategy for patients with multi-vessel coronary artery disease, while acknowledging the increased likelihood of repeat interventions.
