ShanghaiMay 14, 2026 /PRNewswire/ — Before a coronary heart disease attack, there is rarely a clear warning. The risk may have been quietly accumulating in the blood vessels for a long time, but the actual attack often happens in an instant.
For some patients, the condition is far more complex than simply “blocked blood vessels.” When narrowing becomes triple-vessel disease, when a heart attack is complicated by a ventricular aneurysm, or when there is a tumor beyond the heart… what they face is complex coronary artery disease.
At Shanghai DeltaHealth Hospital, cardiologists and cardiac surgeons sit together for daily shift handovers. They are not comparing who has stronger skills, but answering the same question: For this specific patient before us, which path is the right one?
1. What is Complex Coronary Artery Disease?
The heart is the body’s “pump,” and the coronary arteries are the “pipes” specifically responsible for delivering blood to the heart muscle. When these pipes narrow or even become blocked, the heart muscle becomes ischemic—this is coronary artery disease.
The surgical team at DeltaHealth often uses a metaphor to explain: The heart is like a house—it has electrical wiring (heart rhythm), plumbing (coronary arteries), walls (heart muscle), and doors (heart valves). Coronary artery disease means there’s a problem with the plumbing. Blocked or broken pipes can lead to wall damage or doors that don’t close properly. If a person has damage to blood vessels, heart muscle, and valves simultaneously, it constitutes complex coronary artery disease.
Complex coronary artery disease can be defined on two levels:
Complexity of the lesion—triple-vessel stenosis, combined with diabetes, extensive calcification;
Complexity of treatment—poor vascular conditions, difficult interventional procedures, or the patient’s overall poor condition: low cardiac function, unstable circulation, or even combined with other severe diseases.
Simply put, complex coronary artery disease cannot be resolved by merely “unblocking the vessels.” It is often accompanied by acute myocardial infarction, severely reduced cardiac function, and near-circulatory collapse—the condition is critical, and treatment decisions require repeated deliberation.
In cases where surgical intervention is not feasible, DeltaHealth’s close collaboration between internal medicine and surgery opens up a third path for patients.
2. Why Does Complex Coronary Artery Disease Require MDT?
From emergency intervention to surgical bypass, to the synergy of internal medicine and surgery—DeltaHealth offers different treatment pathways for complex coronary artery disease. But the key is: these pathways are not pre-set; they are dynamically selected based on the patient’s specific condition.
DeltaHealth adopts a “major specialty, minor general” model, where cardiology and cardiac surgery are deeply integrated in daily work, with no departmental barriers. The two teams jointly review the patient’s hemodynamic indicators, imaging assessments, and laboratory test trends, and dynamically adjust treatment strategies accordingly—this is fundamentally different from the traditional “referral-consultation” model.
In the traditional model, problems that one department cannot handle are referred to another; at DeltaHealth, the starting point for team decisions is not “Can I do this?” but “What does this patient truly need?”
DeltaHealth’s MDT emphasizes that both bypass and interventional technical capabilities are indispensable. For complex coronary artery disease, the choice of treatment strategy is far more important than the individual operator’s technical proficiency—once the strategy deviates from the correct direction, the more exquisite the technique, the further it may lead down the wrong path.
3. DeltaHealth’s Core Competitiveness in Complex Coronary Artery Disease
- Breaking Down Disciplinary Barriers
Cardiology and cardiac surgery are deeply integrated, not simply “referral” but “co-diagnosis.” The two departments conduct daily joint shift handovers, sharing patient data in real-time to ensure decisions are based on the complete clinical picture. - Patient-Centered Treatment Decisions
Age, metabolic control, family history, cancer history, financial status, family support—these are all important components of decision-making. The responsibility of DeltaHealth doctors is not limited to treating the immediate disease but also considering the patient’s overall condition and long-term prognosis. - Strategy Over Technique
Technical feasibility does not mean it should be implemented. The essence of MDT is to choose the optimal solution based on the condition, not from the technical preference of a single discipline. - Willingness to Tackle High-Difficulty Cases
For patients whom a single discipline might declare “hopeless,” DeltaHealth’s internal medicine and surgery teams join forces, using innovative strategies such as ECMO-assisted interventional therapy, to carve out new possibilities.
Final Thoughts
Complex coronary artery disease has no single standard answer. The key is not which treatment method is more “advanced” or “minimally invasive,” but whether there is a team willing to find the most suitable path for each patient.
At DeltaHealth, from “who will do it” to “how exactly to do it,” from perioperative risk control to long-term prognosis management—every decision is based on the patient’s anatomical and pathophysiological characteristics, not the technical preference of any single discipline.
Facing complex coronary artery disease, it is difficult for one person to make the right choice. But a group of people can.
