Traditional Chinese Medicine Approaches to Coronary Heart Disease: Strengthening the Heart, Boosting Qi, and Promoting Blood Circulation

Coronary artery disease (CAD) remains a leading cause of morbidity and mortality worldwide. While modern cardiology emphasizes risk factor modification, pharmacotherapy, and revascularization, growing clinical interest centers on integrative approaches—including Traditional Chinese Medicine (TCM)—as adjunctive strategies for long-term cardiovascular health maintenance.

In TCM theory, CAD is often categorized under “chest bi syndrome” (Xiong Bi), characterized by impaired flow of Qi and Blood in the Heart and Pericardium channels. Core pathophysiological patterns include Heart Qi deficiency, Blood stasis, Phlegm obstruction, and Yin-Yang imbalance—frequently coexisting in varying combinations. The therapeutic principle focuses not only on symptom relief but also on strengthening the Heart’s functional capacity (“tonifying Heart Qi”), promoting microcirculatory perfusion (“activating Blood and resolving stasis”), and restoring systemic harmony.

Dietary therapy plays a pivotal role in TCM-based CAD management. Emphasis is placed on foods that support Qi generation, nourish Yin, soften hardness, and invigorate circulation—while avoiding those that exacerbate dampness, phlegm, or internal heat. Clinically recommended foods include hawthorn fruit (Shan Zha), known for its lipid-lowering and coronary vasodilatory effects; lotus seed (Lian Zi), used to calm the Shen and stabilize Heart Qi; and black fungus (Mu Er), valued for its antiplatelet and endothelial-protective properties. Moderate intake of green tea, goji berries (Gou Qi Zi), and cooked adzuki beans is also encouraged for their antioxidant, hypotensive, and Blood-invigorating actions.

Conversely, TCM practitioners routinely advise limiting or avoiding fried, greasy, and heavily processed foods; excessive salt and sugar; and cold, raw items—particularly during acute anginal episodes—as these may impair Spleen function, promote Phlegm-Damp accumulation, and further obstruct channel flow. Individualized dietary prescriptions are always guided by pattern differentiation: for example, patients with predominant Qi deficiency may benefit from slow-cooked congees with astragalus (Huang Qi) and jujube (Da Zao), whereas those with marked Blood stasis might receive formulations incorporating turmeric (Jiang Huang) and salvia root (Dan Shen).

It is essential to underscore that TCM dietary interventions are complementary—not alternative—to evidence-based cardiovascular care. Patients should continue prescribed antiplatelet agents, statins, beta-blockers, or antihypertensives unless directed otherwise by their cardiologist. Ongoing collaboration between Western-trained physicians and licensed TCM practitioners ensures safe, coordinated, and patient-centered management grounded in both biomedical science and time-tested holistic principles.
