From the Guidelines
The probability of major clinical outcomes, including mortality, being similar between PCI and CABG for patients with left main CAD at 1- to 2-year follow-up is higher, but repeat revascularization rates are higher after PCI than after CABG. When considering the treatment options for left main coronary artery disease (CAD), the choice between percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) is critical. The evidence from studies such as the SYNTAX trial 1 and other randomized controlled trials (RCTs) suggests that while major clinical outcomes, including mortality, are similar between PCI and CABG at short-term follow-up, there are differences in the rates of repeat revascularization.
Key Considerations
- The SYNTAX trial found that at 1 year, rates of all-cause death and major adverse cardiac or cerebrovascular events (MACCE) were similar among patients who had undergone drug-eluting stent (DES) placement and those who had undergone CABG 1.
- However, repeat revascularization was performed more often in the DES group than in the CABG group, indicating a potential long-term advantage of CABG in terms of reducing the need for further interventions 1.
- The LE MANS and PRECOMBAT trials also support the notion that while short-term outcomes may be similar, the choice between PCI and CABG should consider the individual patient's risk profile and the complexity of their coronary disease 1.
Evidence Summary
The current evidence base, including RCTs and observational studies, does not definitively prove that one method is superior to the other in all cases but suggests that the decision should be tailored to the individual patient's condition, including the severity and complexity of their coronary artery disease.
Clinical Implications
In clinical practice, the decision between PCI and CABG for left main CAD should be made based on a comprehensive assessment of the patient's overall health, the specific characteristics of their coronary disease, and their personal preferences, with the goal of minimizing morbidity, mortality, and the need for repeat interventions. The choice between PCI and CABG should prioritize the patient's quality of life and long-term outcomes, considering the potential for repeat revascularization and other complications.

From the Research
Probability Assessment
To determine what is more probable, we need to analyze the given studies and identify relevant information. However, the provided studies do not directly address the concept of probability or compare the likelihood of specific events.
Study Analysis
- The study 2 focuses on patient perspectives and understanding regarding multidisciplinary team (MDT) meetings in cancer care, highlighting the need for patient-centered approaches.
- The study 3 discusses guideline adaptation frameworks, emphasizing the importance of considering local context in implementing evidence-based guidelines.
- The study 4 explores the relationship between context and clinical reasoning, identifying three epistemological dimensions: representational, interactional, and interpretative.
- The study 5 investigates the role of procedural justice in compliance with medical advice, finding that fair treatment of patients can increase acceptance and compliance.
- The study 6 presents a session recommendation model based on context-aware and gated graph neural networks, demonstrating improved performance in session-based recommendation tasks.
Relevance to Probability Assessment
Unfortunately, none of the provided studies directly address the concept of probability or provide comparative likelihoods of specific events. Therefore, it is challenging to determine what is more probable based on the given evidence.
