Conventional medicine
Chest tightness is cardiac until proven otherwise. Rule out ACS, then work down: pulmonary, GI, MSK, anxiety. Imaging and stress testing close the loop.
Breath-first / nervous system
Once cardiac is cleared, most chronic chest tightness traces to over-breathing, shallow apical patterns, anxious sympathetic tone, or thoracic mobility. The fix is mechanical and neural, not pharmacological.
Crushing pain, radiation to arm/jaw, sweating, dyspnea, syncope, or known CAD → call 911. Otherwise: ECG, vitals, history, exam.
Holistic work starts AFTER ECG and cardiac risk assessment. New, exertional, or radiating pain → ER. This track only applies to cleared, recurrent, non-cardiac tightness.
12-lead ECG, troponin x 1–3 if recent symptoms, lipid panel, TSH, CBC. Rule out ischemia, arrhythmia, electrolyte.
BOLT score (breath-hold tolerance). Nasal-only breathing 24/7. Mouth tape at night. Cap exhale length 2x inhale. Identify hyperventilation or paradoxical breathing.
Treadmill ECG (if can exercise), or stress echo / nuclear if not. Coronary CT angiography (CCTA) for moderate-risk; calcium score for low-risk.
90-90 breathing, crocodile breathing, ribcage mobility. Slouch / forward-head correction. Train diaphragm vs accessory muscle dominance.
Review tests, optimize statins / BP / antiplatelets. Holter or event monitor if arrhythmia suspected. Address risk factors.
Physiological sigh (2 inhales + long exhale) for acute episodes. Daily cold exposure, humming, gargling. CO2 tolerance work (Buteyko-style).
Diagnostic cath if non-invasive testing positive or high-risk. PCI with stent for obstructive lesions; CABG for multi-vessel disease.
Nasal breathing always. 5 min slow breath daily (5.5 br/min). Mouth tape at night. Weekly BOLT check. Cold exposure 2–3x / wk. Walk 8k+.
Every step has a price.

Who built
track B.
Consolidated from breath researchers and practitioners. Use only AFTER cardiac and pulmonary causes are ruled out.
"Mouth-breathing is a slow-motion disease." Nose-only, slow exhales, mouth tape at night.
BOLT score + CO2 tolerance training reduces breathlessness, anxiety, exercise-induced tightness.
Physiological sigh is the fastest known way to down-regulate stress in real time. Two inhales, long exhale.
CO2 tolerance is trainable. Most chronic chest tightness is over-breathing in disguise.
