CABG for patients with heart dysfunction: when and why to refuse surgery.

Area of Science:

• Cardiology
• Cardiac Surgery
• Interventional Cardiology

Background:

• Surgical myocardial revascularization for reduced left ventricular function remains debated.
• The STICH trial's 10-year follow-up provides crucial long-term data.
• Optimal patient selection for revascularization is challenging.

Purpose of the Study:

• To review evidence on revascularization in patients with reduced left ventricular function.
• To clarify patient selection criteria for surgical intervention.
• To compare coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in this population.

Main Methods:

• Review of observational and investigational studies.
• Analysis of STICH trial 10-year extension follow-up data.
• Evaluation of preoperative patient characteristics as risk factors.

Main Results:

• Conclusive evidence supports surgical myocardial revascularization benefits.
• New data identifies patient characteristics influencing surgical risk and benefit.
• Understanding relative indications for CABG versus PCI is improving.

Conclusions:

• Surgical revascularization is beneficial for selected patients with CAD and low ejection fraction.
• Improved patient selection strategies are emerging.
• Further clarification on CABG vs. PCI indications is needed for this cohort.
