Insights
Long-term follow-up of percutaneous transluminal coronary angioplasty (PTCA) shows a 79% success rate. At three years, most patients remained asymptomatic and returned to work, indicating sustained benefits of PTCA.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Medicine
Context:
- Percutaneous transluminal coronary angioplasty (PTCA) is a common procedure for treating coronary artery disease.
- Assessing the long-term outcomes and patient well-being after PTCA is crucial for clinical practice.
Purpose:
- To evaluate the long-term efficacy and patient outcomes following percutaneous transluminal coronary angioplasty (PTCA).
- To assess success rates, recurrence of symptoms, and return to work post-angioplasty.
Summary:
- A 3-year follow-up of 130 patients (79% of 165) who underwent PTCA between 1980-1984 revealed a primary success rate of 79%.
- In-hospital mortality was 0%, with 7% requiring emergency bypass surgery. Angina recurrence occurred in 18 patients within 6 months and 3 after 1 year, with 10% experiencing restenosis.
- At 3 years, 76% of patients were asymptomatic, 8% improved, and 83% had returned to full-time employment.
Impact:
- The study demonstrates the sustained clinical benefit and positive impact of PTCA on patient quality of life, including symptom relief and return to work.
- Findings support PTCA as an effective revascularization strategy with favorable long-term results in selected patients.
Abstract:
The authors report on the longterm follow-up after PTCA in 130/165 (79%) patients seen approximately 3 years after angioplasty. Primary success rate in the years 1980-84 was 79%. Emergency bypass surgery was necessary in 7%. In-hospital mortality was 0%. Recurrences of angina were seen in the first 6 months in 18 and after 1 year in 3 patients. 13 of 18 had a recurrence of the dilated lesion (10%). At 3 years there had been 4 cardiac deaths, 76% were asymptomatic, 8% were improved and 83% were working full time.
