Summary

Percutaneous transluminal coronary angioplasty (PTCA) is effective for stable angina, with high success rates and significant long-term symptom relief for most patients. This procedure demonstrates its importance in managing coronary artery disease.

Area of Science:

  • Cardiology
  • Interventional Cardiology

Background:

  • Stable angina remains a significant clinical challenge, impacting patient quality of life and prognosis.
  • Percutaneous transluminal coronary angioplasty (PTCA) is a common revascularization strategy for stable coronary artery disease.

Purpose of the Study:

  • To evaluate the long-term efficacy and safety of percutaneous transluminal coronary angioplasty (PTCA) in patients with stable angina.
  • To assess the rates of procedural success, late mortality, myocardial infarction, and angina recurrence following PTCA.

Main Methods:

  • Retrospective analysis of 345 patients undergoing PTCA for stable angina over a 5-year period.
  • Average follow-up duration of 34 months (range 12-72 months).
  • Assessment of primary success rate, late mortality, myocardial infarction, angina recurrence, and need for repeat procedures (PTCA or coronary artery bypass grafting).

Main Results:

  • High primary success rate of 94.5% for PTCA.
  • Low rates of late mortality (1.5%) and myocardial infarction (2.1%).
  • Angina recurrence observed in 34.5% of patients, with 28.5% requiring repeat PTCA and 7% undergoing coronary artery bypass grafting. At follow-up, 79.5% were angina-free, and 10% showed improvement.

Conclusions:

  • PTCA is a safe and effective treatment for stable angina, offering significant long-term symptom relief and improved quality of life for the majority of patients.
  • The data underscore the continued importance of PTCA as a cornerstone therapy in the management of stable coronary artery disease.
  • While recurrence rates necessitate monitoring, the overall outcomes support PTCA's role in revascularization strategies.
