Summary
Percutaneous transluminal coronary angioplasty (PTCA) is effective for patients with reduced ejection fraction, except in complex cases. Patients with ejection fraction ≤0.40 experienced similar complication rates to those with normal ejection fraction, indicating PTCA
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
Context:
- 1132 percutaneous transluminal coronary angioplasties (PTCA) performed between 1987-1989.
- Patients divided into Group A (ejection fraction ≤0.40) and Group B (ejection fraction >0.40).
Purpose:
- To evaluate the efficacy and safety of PTCA in patients with reduced ejection fraction.
- To compare outcomes between patients with reduced and normal ejection fraction undergoing PTCA.
Summary:
- Overall PTCA success rate was 95% for stenosed and 56% for totally obstructed vessels.
- 36 major complications occurred (7 deaths, 10 myocardial infarctions, 19 bypasses).
- Subgroup A1 (reduced ejection fraction, sole patent vessel) had low success (44%) and high complication rates.
Impact:
- PTCA in patients with ejection fraction ≤0.40 is generally safe and effective.
- Patients with reduced ejection fraction and complex coronary artery disease require careful consideration.
- Outcomes for most patients with reduced ejection fraction were comparable to those with normal ejection fraction.
