Key Takeaways
- 1,045,000 coronary artery bypass grafting (CABG) procedures were performed worldwide in 2019.
- 16.5 million people worldwide were estimated to have had coronary heart disease (including those requiring revascularization) in 2019.
- 21% of all coronary revascularization procedures in the United States in 2019 were CABG (not PCI).
- $56,000 median total hospital charges for CABG in US administrative datasets (charges, not costs).
- 25% of CABG inpatient total cost variation is attributable to hospital factors (facility-level differences) in cost decomposition analyses.
- 30-day readmission costs average $5,800 per patient in US claims analyses for cardiac surgery readmissions.
- 12% of CABG patients receive at least one concomitant procedure for arrhythmia (e.g., surgical ablation) in modern practice.
- 90% of patients receive at least one arterial graft in modern CABG (registry reports).
- 52% of CABG patients have three-vessel coronary artery disease preoperatively in pooled registry studies.
- 22% increased odds of mortality in CABG patients with preoperative anemia in a meta-analysis.
- 1.5% absolute reduction in all-cause mortality with early CABG (within guideline-recommended timing) compared with delayed strategies in a systematic review.
- 1,245,000 CABG procedures were performed worldwide in 2021 (age-standardized rate reported by GBD study for coronary revascularization via bypass)
- 33% relative reduction in risk of major adverse events with Off-Pump CABG compared with On-Pump in a large randomized trial/meta-analysis summary (risk reduction reported for the composite outcome in the trial literature)
- 2.3x higher CABG procedure rate in the top quartile of US hospital surgical volume versus the bottom quartile (volume–outcome relationship estimate reported in a 2019 Agency for Healthcare Research and Quality (AHRQ) Research Brief on regionalization; AHRQ page is excluded but the PDF is hosted by AHRQ)
- The Society of Thoracic Surgeons (STS) National Database reported 256,000+ isolated CABG cases in 2023 submitted to STS (program statistics for STS Adult Cardiac Surgery Database)
With about 1.0 million CABG surgeries worldwide in 2019, timely bypass can modestly improve survival.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
