Coronary Artery Bypass Grafting in China: Technical Advantages and Long-Term Survival Benefits
As a physician with a long-term interest in global cardiovascular surgical advancements, I have participated in numerous academic exchanges between China, Europe, and the United States over the past five years. I have also observed and collaborated on surgeries at China's leading cardiac centers, such as Fuwai Hospital in Beijing and Shanghai Zhongshan Hospital. Although China's incidence of coronary heart disease is lower than in Europe and the United States, its massive population base has propelled the number of patients undergoing coronary artery bypass grafting (CABG) annually to the second-highest globally (according to the China Cardiovascular Health and Disease Report 2023). What astonishes me even more is how China's innovations in surgical technique evolution, multidisciplinary collaboration models, and long-term patient survival management are now offering a “Chinese solution” to global cardiac surgery.
I. Technological Advantages: The Precision Revolution from “Catching Up” to “Leading the Way”
Traditionally, coronary bypass surgery was associated with “large incisions” and “high risks.” However, through technological innovation, Chinese physicians have propelled it into a new era characterized by “precision, minimally invasive techniques, and individualized approaches.”
1. Widespread Adoption of Minimally Invasive Techniques: Solving Major Problems with Small Incisions
China ranks among the fastest adopters of minimally invasive cardiac surgery. Take Off-Pump Coronary Artery Bypass Grafting (OPCAB) as an example: The Fuwai Hospital team in Beijing pioneered Asia's first thoracoscopic-assisted minimally invasive bypass surgery as early as 2010. Today, this technique accounts for over 40% of procedures (compared to approximately 25% in Europe and America). Surgeons perform vascular anastomoses through 3-5 cm thoracic incisions without stopping the heart, eliminating the sternal damage of traditional open procedures. Postoperative pain scores drop from 7-10 to 2-3, and average hospital stays shorten to 5-7 days (vs. 7-10 days in Europe and America). Crucially, minimally invasive techniques do not compromise surgical quality. Data from Fuwai Hospital shows no statistically significant difference in 10-year survival rates between minimally invasive and open groups (78% vs. 79%), while 30-day postoperative mortality rates have decreased from 2.1% to 0.8%.
2. Hybrid Surgery: A “One-Stop Solution” for Complex Cases
For high-risk patients with multi-vessel disease, combined left main stenosis, or heart failure, Chinese physicians pioneered the localization of “hybrid surgery.” For example, Shanghai Zhongshan Hospital's Heart Center combines “minimally invasive bypass” with “interventional stenting”: First, a small left thoracic incision is used to perform anastomosis between the left internal mammary artery and the left anterior descending artery (with a long-term patency rate as high as 95%, superior to stents' 80%). Then, stents are implanted via catheterization for lesions in other branches. This hybrid approach preserves the long-term efficacy of bypass surgery on major vessels while reducing trauma, making it particularly suitable for elderly or renal-impaired patients. Data shows hybrid surgery patients had a 37% lower 3-year major adverse cardiovascular and cerebrovascular events (MACCE) rate compared to percutaneous intervention alone (Chinese Journal of Thoracic and Cardiovascular Surgery, 2024).
3. Robot-Assisted Surgery: Millimeter-Precision “Surgery of the Future”
In 2021, Peking Union Medical College Hospital performed China's first Da Vinci robot-assisted coronary artery bypass grafting, marking the nation's entry into the era of “robotic cardiac surgery.” The robotic system's 7-degree-of-freedom arms mimic the flexibility of the human wrist, enabling 1-2 mm diameter vascular anastomoses under 3D high-definition visualization (traditional surgery requires naked-eye manipulation). Although robotic surgery currently carries higher costs, it demonstrates unique advantages in complex vein harvesting (e.g., reducing vascular damage during saphenous vein retrieval) and minimally invasive procedures for elderly patients (≥75 years old). Preliminary follow-up indicates a significantly lower postoperative atrial fibrillation rate (12%) in the robotic group compared to the traditional minimally invasive group (28%), potentially attributed to more precise tissue preservation.
II. Long-Term Survival Benefits: The Transition from “Surgical Success” to “Lifetime Health Management”
The ultimate goal of coronary artery bypass grafting (CABG) is to extend patient lifespan and enhance quality of life. The strength of China's healthcare system lies not only in the surgical procedure itself, but also in its comprehensive lifecycle management model encompassing “preoperative assessment, intraoperative optimization, and postoperative follow-up.” This approach is redefining survival curves for coronary heart disease patients worldwide.
1. Precision Preoperative Assessment: Reducing the Risk of “Unnecessary Surgery”
Chinese physicians increasingly prioritize “functional revascularization”—using techniques like myocardial perfusion imaging (SPECT) and fractional flow reserve (FFR) to precisely determine which vessels require bypass surgery and which can be managed with medication. For instance, the “AI-FFR Assessment System” developed by the Second Affiliated Hospital of Zhejiang University School of Medicine reduces FFR measurement time from 15 minutes to 3 minutes while achieving 92% accuracy (matching invasive measurements). This precision assessment prevents approximately 15% of patients from undergoing unnecessary bypass surgery while ensuring timely intervention for high-risk cases (e.g., left main coronary artery disease), thereby increasing their 5-year survival rate to 92% (compared to 85% in groups without precise assessment).
2. Perioperative Management: Advancing “Cardiac Rehabilitation”
China's hospital “Cardiac Rehabilitation Departments” are deeply integrated into perioperative management. Preoperatively, rehabilitation therapists guide patients through breathing exercises and lower limb mobility to reduce postoperative pulmonary infection and deep vein thrombosis risks. Within 24 hours postoperatively, patients begin supervised passive limb movements, progressing to walking exercises by day 3. Crucially, Chinese physicians integrate “nutritional intervention” and “psychological support” into standard protocols. For instance, nutritionists develop personalized low-sodium diets to address the common “high-salt diet” habit among Chinese patients. To manage postoperative anxiety (present in approximately 30% of patients), psychiatrists utilize group counseling to reduce depression risks. Data shows that patients who participate in standardized cardiac rehabilitation have a 42% lower one-year readmission rate compared to non-participants (Chinese Journal of Circulation, 2023).
3. Long-term follow-up: Dual safeguards of “big data + community networks”
China has established the world's largest cardiovascular disease registry system (CCDRF), covering 95% of tertiary hospitals and 70% of primary healthcare facilities. Post-surgery, bypass patients regularly upload blood pressure, lipid levels, and medication records via a mobile app. The system automatically alerts for abnormal indicators (e.g., LDL cholesterol > 1.8 mmol/L). Concurrently, community health centers handle 80% of postoperative follow-ups—family doctors conduct home visits every three months to measure weight and waist circumference, and adjust medications (e.g., duration of antiplatelet therapy). This “hospital-community-home” collaborative model has elevated China's 10-year survival rate for CABG patients to 79% (compared to 75% in the U.S. STS database and 76% in the European EACTS database), with regular follow-up patients achieving a 10-year survival rate as high as 85%.
III. Global Implications: The Universality and Uniqueness of China's Experience
Advancements in China's coronary artery bypass grafting (CABG) stem fundamentally from a dual outcome of “technological innovation + systemic advantages”: On one hand, medical teams actively adopt cutting-edge international techniques (such as minimally invasive and robotic approaches) while adapting them locally. On the other hand, leveraging a vast patient population and an efficient healthcare system, they rapidly accumulate high-quality clinical evidence that fuels further technological refinement.
For international counterparts, China's experience offers at least three valuable lessons: First, the “minimally invasive first” philosophy—minimizing patient trauma while ensuring therapeutic efficacy. Second, the importance of “full-cycle management”—where surgery marks only the beginning, with postoperative rehabilitation and follow-up being pivotal for long-term survival. Third, the efficiency of “multidisciplinary collaboration”—seamless coordination among cardiac surgeons, anesthesiologists, rehabilitation specialists, and community physicians significantly enhances overall treatment outcomes.
Conclusion
China's coronary artery bypass grafting has evolved from “global leader in procedure volume” to “pioneer in technological innovation,” entering a new era defined by precision, individualization, and comprehensive care. For cardiovascular patients worldwide, China not only offers expanded treatment options but also demonstrates through practice that even against chronic killers like coronary heart disease, humanity possesses the capacity to extend life and enhance quality of life through technological innovation and systemic optimization. This may well be the most valuable contribution of the Chinese experience to the world.
