Non-Cardiac Chest Pain
Chest discomfort not related to heart problems.
TL;DR
Non-cardiac chest pain is only diagnosed after the heart has been properly ruled out — never assume chest pain is benign without evaluation. Once cardiac causes are excluded, reflux is the most common culprit, followed by chest-wall pain and anxiety. Acid suppression, stress management, and targeted treatment of the actual cause all have evidence; supplements are peripheral.
Overview
Chest pain that persists after a cardiac cause has been ruled out — most often originating from the oesophagus (acid reflux, spasm, hypersensitivity), the chest wall (costochondritis, muscle strain), or anxiety. The critical first step is always excluding the heart; only then does the label non-cardiac apply.
Root Causes
Evidence synthesis: Once cardiac disease is excluded, studies attribute 20-60% of non-cardiac chest pain to gastro-oesophageal reflux, and PPI trial therapy is both a diagnostic and therapeutic evidence-based step. Oesophageal hypersensitivity and spasm account for a further share, with some trial support for low-dose antidepressants (imipramine) in refractory cases. Chest-wall pain (costochondritis) is supported by physical exam findings and responds to anti-inflammatories and physiotherapy principles. Panic disorder is a major under-recognised cause — hyperventilation and muscle tension produce genuine chest pain — and responds to CBT. Ginger has trial evidence for functional dyspepsia and gastric emptying, relevant when upper-GI symptoms accompany the pain, but no direct chest-pain trials exist.
How It's Diagnosed
When to See a Doctor
Never self-diagnose chest pain. Call emergency services for pain with breathlessness, sweating, nausea, or pain spreading to the jaw or arm. Even with a prior non-cardiac diagnosis, new or different chest pain deserves fresh assessment.
