Which condition is an indication for CABG?

Which condition is an indication for CABG?

• A. Presence of significant multi-vessel coronary artery disease
• B. Single-vessel disease
• C. No disease
• D. Asymptomatic arrhythmia

Answer: (A)

CABG is typically reserved for extensive coronary disease where bypass grafts can restore blood flow to multiple heart regions and achieve durable revascularization. When there is significant multi-vessel disease—especially with left main involvement or three-vessel disease—CABG tends to provide better long-term outcomes and symptom relief than other approaches. Single-vessel disease is often treated with PCI or medical therapy, no disease means there’s nothing to bypass, and an asymptomatic arrhythmia is managed by rhythm or device therapies rather than bypass surgery. So, the scenario with significant multi-vessel coronary artery disease is the indication for CABG.
