Angina pectoris (adjunct)
Last updated: 2026-09-20 · Prepared by licensed TCM physicians · Updated 2026-09
Key Points
Angina is episodic chest pain or tightness from temporary insufficient coronary blood flow, usually triggered by exertion, emotion or cold, and relieved by rest or nitroglycerin. In TCM it is "chest obstruction" (xiong bi); this page positions care as adjunct to standard cardiology treatment.
- Typical episodes are crushing substernal tightness lasting minutes, eased by rest or nitroglycerin
- It is an important warning sign of coronary artery disease and must first be diagnosed and treated by a cardiologist
- Acupuncture and herbs are adjunctive — not a substitute for antiplatelets, statins or revascularization
- A change in pattern, more frequent or prolonged pain may mean unstable angina — an emergency
First, what cannot wait
- Crushing chest pain lasting ≥15 minutes, not relieved by nitroglycerin, with sweating, nausea or radiation to the left arm — call emergency (possible heart attack)
- Pain at rest or with minimal effort, newly worsening, or waking you at night — unstable angina, emergency now
- Chest pain with loss of consciousness, greyish face or weak pulse — call emergency
- Sudden breathlessness with chest pain and coughing blood — rule out pulmonary embolism, emergency now
- A recent change in the pattern of stable angina
- Marked drop in exercise tolerance, triggered by trivial daily tasks
- With diabetes, kidney disease or prior heart attack — needs close specialist follow-up
Understanding the Condition
The heart needs its own "fuel pipes" — the coronary arteries. When plaques narrow them and flow runs short, the muscle "cries hunger" as crushing tightness, like a stone on the chest.
Unlike a heart attack, angina is usually transient: once flow returns (rest or medication) the pain eases. But it is a clear warning — the vessel is already signalling.
Why It Keeps Coming Back
Because it bears directly on heart-attack and sudden-death risk. Treating angina as "an old ache to endure" can miss the window to stabilize plaques and disease.
Standard drugs (antiplatelet, statin, rate/BP control) are the foundation; acupuncture and herbs are adjuncts that help reduce frequency, improve exercise tolerance and quality of life — not a replacement.
Our Pattern-Based Approach
A clinically common adjunctive approach "opens yang, disperses obstruction, moves blood and qi": qi stagnation with blood stasis (stabbing pain, emotion-triggered); phlegm obstruction (overweight, breathless, greasy coat); heart yang deficiency (chill, worse on effort); qi-yin deficiency (palpitations, fatigue, dry mouth).
Acupuncture often uses Neiguan (PC6), Danzhong (CV17), Xinshu (BL15) and Jueyinshu (BL14) to widen the chest, move qi and unblock vessels, with a light diet and emotional management. Crucially, this sits on top of cardiology care; in an acute attack, nitroglycerin and emergency steps come first.
Common patterns and treatment directions
| Pattern | Typical presentation | Approach |
|---|---|---|
| Qi stagnation with blood stasis | Stabbing chest tightness, fixed location, emotion-triggered, dark tongue | Move qi and blood: Neiguan (PC6), Danzhong (CV17), Geshu (BL17), focus on easing emotion |
| Phlegm obstruction | Oppressive chest, overweight, breathless, greasy coat | Open yang and drain turbidity: Fenglong (ST40), Zhongwan (CV12), Danzhong (CV17), low-fat diet |
| Heart yang deficiency | Chill, cold limbs, chest pain worse on effort, pale face | Warm and unblock heart yang: Xinshu (BL15), Jueyinshu (BL14), Guanyuan (CV4), keep warm |
| Qi-yin deficiency | Palpitations, short breath, fatigue, dry mouth, effort-triggered | Tonify qi and nourish yin: Zusanli (ST36), Sanyinjiao (SP6), Neiguan (PC6) |
| Cold congealing the heart vessel | Cold-triggered, sudden chest pain, cold limbs | Acrid-warm to unblock vessels: Neiguan (PC6), Zhiyang (GV9), Mingmen (GV4), prevent cold |

What to expect: first visit to follow-up
- First visit · about 40 minutesBring your cardiology notes, medications and tests (angiography/CTA, ECG). We take history, pulse, tongue and pattern, while checking red flags and referring to cardiology first if needed.
- Plan discussion · same dayWe explain the pattern and adjunctive role, clarify when to work with cardiology, and the emergency principles for acute attacks.
- Weeks 1-4One to two sessions per week, focused on fewer episodes and better exercise tolerance; you keep an episode diary.
- Week 4-8 · first reviewCompare diary and symptoms before and after; decide to continue, adjust points or move to maintenance. Drug regimen stays under cardiology.
Course of care and follow-up
- Assessment usually runs in 4-8 week cycles alongside cardiology reviews
- Once stable, care may shift to maintenance every 2-4 weeks
- Pattern is re-assessed yearly or when angina pattern changes
- We work with your cardiologist throughout: never stop or reduce antiplatelet/statin; follow emergency steps in acute attacks
When to Seek Care
Before your visit:
- Carry and keep nitroglycerin as prescribed; log each episode’s trigger, duration and relief
- Avoid sudden strenuous exercise, cold exposure and emotional stress; stop smoking and limit alcohol
- Take prescribed drugs (antiplatelet, statin) consistently; never stop or reduce on your own
Consider an in-person consultation if:
- Episodes more frequent, severe or longer, or triggered by less activity
- Not relieved within 15 minutes by rest or nitroglycerin
- With sweating, nausea or breathlessness — see a doctor promptly
Supportive Care
- Medication: strictly follow antiplatelet and statin therapy; carry nitroglycerin
- Diet: low salt and fat, more vegetables and fruit, control weight and calories
- Exercise: cardiologist-approved cardiac-rehab aerobic, gradual, avoid breath-holding
- Emotions: chest obstruction is tightly linked to mood; the aim is to "smooth qi", not bottle it up
FAQ
Can acupuncture replace coronary artery disease treatment?
No. The cornerstone is cardiology care (antiplatelet, lipid control, risk-factor management, revascularization when needed). Acupuncture and herbs are only adjuncts that ease symptoms and improve quality of life — never stop or delay proper treatment because of them.
Besides nitroglycerin, what do I do in an attack?
Stop activity and sit down to rest, take nitroglycerin as prescribed; if not relieved in 15 minutes, or if pain is severe with sweating or nausea, call emergency at once. Acupuncture addresses daily prevention and recovery, not on-the-spot acute treatment.
