Quintuple Bypass (CABG) Survival Rates: 5-Year and 10-Year Outcomes

Coronary Artery Bypass Grafting (CABG) with 5 grafts (quintuple) indicates extensive coronary disease.

Survival Data (STS Database, Contemporary Cohorts)

• Operative mortality: 1–3% (varies by risk score: STS/EuroSCORE).
• 5-year survival: 85–90%.
• 10-year survival: 70–80%.
• 20-year survival: ~50% (limited by age, comorbidities, graft failure).

Key Determinants

• Age, LV function, diabetes, renal disease, urgency, surgeon/hospital volume.
• Graft type: Arterial (LIMA, radial) > venous (SVG) patency.
• Medical therapy adherence (statins, antiplatelets, β-blockers, ACEi/ARB).
• Lifestyle: smoking cessation, cardiac rehab, diet, weight control.

Individual prognosis discussed with cardiac surgeon/cardiologist.
