[Stable angina: long-term results]
Insights
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.
Abstract:
We report on 345 patients who underwent percutaneous transluminal coronary angioplasty (PTCA) for stable angina in a 5-year period, with an average follow-up of 34 months (range 12-72). The primary success rate was 94.5%. The late mortality and incidence of myocardial infarction were 1.5% and 2.1% respectively. The rate of recurrence of angina was 34.5% and required PTCA (28.5%) and/or coronary artery bypass grafting (7%). At the end of follow-up 79.5% of patients were free from angina and a further 10% had improved. Our data confirm the importance of PTCA in stable angina.
