Evidence-based Management of Left Main Coronary Artery Disease

Area of Science:

• Cardiovascular Medicine
• Interventional Cardiology

Background:

• Left main coronary artery disease (LMCAD) poses significant risks.
• Revascularisation is crucial for improving survival in most LMCAD patients.

Purpose of the Study:

• To review key studies comparing coronary artery bypass grafting surgery (CABG) and percutaneous coronary intervention (PCI) for LMCAD.
• To analyze the evolving treatment strategies for LMCAD.

Main Methods:

• Systematic review of randomized clinical trials and meta-analyses.
• Analysis of studies comparing CABG versus PCI in LMCAD patients.

Main Results:

• Controversial results exist between CABG and PCI in LMCAD treatment.
• PCI is becoming a viable alternative, especially for patients with comorbidities or contraindications to CABG.

Conclusions:

• The optimal revascularisation strategy for LMCAD requires careful consideration of coronary anatomy, clinical factors, and patient preferences.
• Guidelines support CABG as standard, but advancements in PCI offer a feasible alternative in specific patient groups.
