Chest Pain Etiology: Common Causes and Epidemiology
Chest pain is a frequent reason for medical consultation in both adults and children, with causes ranging from benign to life-threatening conditions. The underlying etiology can be cardiac, pulmonary, gastrointestinal, musculoskeletal, or psychogenic in nature, and the distribution of these causes varies by age group and clinical setting 26910.
Cardiac Causes of Chest Pain
Cardiac etiologies are among the most serious causes of chest pain, though they account for a minority of cases overall. In adults, cardiac causes include ischemic heart disease (such as acute coronary syndrome and stable angina), arrhythmias, pericarditis, myocarditis, aortic dissection, and heart failure 4689. In primary care, stable ischemic heart disease is found in about 11% of patients with chest pain, while acute coronary syndrome accounts for approximately 3.6% . In children, cardiac causes are rare, representing less than 1% of cases, but can include arrhythmias, pericarditis, myocarditis, myocardial infarction, and, rarely, pulmonary embolism 25.
Non-Cardiac Causes: Musculoskeletal, Pulmonary, Gastrointestinal, and Psychogenic
Non-cardiac causes are much more common. Musculoskeletal pain is the leading etiology in both adults and children, accounting for 38.7–86.3% of pediatric cases and 46.6% of adult cases in primary care 25710. Pulmonary causes (such as asthma, wheezing, cough, and infections) and gastrointestinal causes (like reflux or esophageal spasm) are also frequent, with pulmonary causes making up 1.8–12.8% and gastrointestinal causes 0.3–9.3% of pediatric cases 257. Psychogenic chest pain, including anxiety and panic disorders, is another significant contributor, especially in children, where it can account for up to 83.6% of cases 210.
Diagnostic Approach and Challenges
Distinguishing between cardiac and non-cardiac chest pain can be challenging, as symptoms often overlap. A thorough history and physical examination are essential, but additional testing is often required. In adults, imaging and cardiac testing (such as ECG, echocardiography, and advanced imaging like CCTA or cardiac MRI) are used to clarify the diagnosis, especially when cardiac causes are suspected 368. In children, diagnostic tools like ECG and chest radiography have limited sensitivity for cardiac causes, and most cases can be managed with careful clinical evaluation to avoid unnecessary testing 25.
Epidemiology and Clinical Implications
Chest pain is more common in women and increases with age in the adult population . The majority of cases seen in primary care are non-cardiac, with musculoskeletal and psychogenic causes predominating 25710. Accurate terminology and careful assessment are crucial to avoid misdiagnosis and unnecessary healthcare utilization .
Conclusion
Chest pain has a broad differential diagnosis, with non-cardiac causes being most common in both adults and children. Cardiac causes, while less frequent, are potentially life-threatening and require prompt identification. A structured approach using history, physical examination, and targeted diagnostic testing is essential for accurate diagnosis and effective management 2456+4 MORE.
