Understanding the Causes of Chest Pain
Chest pain is a common symptom that can arise from a variety of conditions, ranging from benign to life-threatening. Understanding the potential causes and the importance of timely diagnosis is crucial for effective management.
Common Causes of Chest Pain
Gastroesophageal Reflux Disease (GERD) and Indigestion
One of the most frequent non-cardiac causes of chest pain is gastroesophageal reflux disease (GERD), where stomach acid flows back into the esophagus, causing a burning sensation in the chest. This pain can be exacerbated by factors such as smoking, alcohol, coffee, fatty foods, and certain medications. Simple remedies like antacids or milk can often provide quick relief1 3.
Musculoskeletal Issues
Muscle strains and inflammation, particularly in the spaces between the ribs (costochondritis), can also lead to chest pain. This type of pain is often reproducible by palpation and is more likely to be musculoskeletal rather than ischemic1 2.
Respiratory Conditions
Respiratory issues such as pleurisy (inflammation of the tissue lining the lungs), bronchitis, and other chest infections can cause significant chest pain. Shingles (herpes zoster) can also present with chest pain before the appearance of a skin rash1 4.
Cardiac Causes
Angina and Myocardial Infarction
Chest pain of cardiac origin is often due to ischemic heart disease. Angina pectoris, a type of chest pain caused by reduced blood flow to the heart, typically occurs during physical exertion or emotional stress and subsides with rest. If untreated, angina can lead to a heart attack (myocardial infarction), which is a more severe and life-threatening condition1 3 6.
Other Cardiac Conditions
Other serious cardiac conditions that can cause chest pain include aortic dissection and perimyocarditis. These conditions require immediate medical attention and thorough diagnostic evaluation, including ECG and imaging tests6 9.
Psychological Factors
Psychological and psychiatric conditions, such as anxiety and panic disorders, can also manifest as chest pain. Hyperventilation syndrome (HVS) is a notable example where chest pain is a prominent symptom. Differentiating between HVS and cardiac-related chest pain is essential to avoid unnecessary invasive procedures5 3.
Diagnostic Approaches
Initial Assessment
A thorough history and physical examination are critical in the initial assessment of chest pain. Key diagnostic tools include chest radiographs and electrocardiograms (ECGs). For patients with exertional chest pain or those with cardiac risk factors, further evaluation with troponin levels and cardiac stress testing is recommended2 8.
Advanced Diagnostic Tests
For suspected pulmonary embolism, a D-dimer assay followed by helical computed tomography or venous ultrasound may be necessary. In cases of suspected pneumonia, clinical signs such as fever and dullness to percussion, confirmed by chest radiograph, are indicative2 9.
Clinical Prediction Rules
Clinical prediction rules and diagnostic pathways, such as the Marburg Heart Score, help in stratifying the risk and guiding the diagnostic process in primary care settings. These tools are designed to balance the need for thorough evaluation with the avoidance of overtesting8 10.
Conclusion
Chest pain can stem from a wide range of causes, from benign conditions like GERD and musculoskeletal issues to serious cardiac and respiratory diseases. Accurate diagnosis through a combination of clinical assessment and targeted diagnostic tests is essential for effective management. Understanding the potential causes and the appropriate diagnostic approaches can significantly improve patient outcomes and prevent life-threatening complications.

Diagnosing the cause of chest pain.
Chest pain can be accurately diagnosed through a thorough history, physical examination, and various diagnostic tests, including troponin levels, cardiac stress testing, and D-dimer assays.
Highly CitedChest pain of cardiac and noncardiac origin.
Chest pain can be accurately diagnosed and treated based on its cause, with gastroesophageal disorders being the most prevalent noncardiac cause.
Highly CitedEvaluation of chest pain in primary care patients.
This paper highlights the importance of accurately identifying life-threatening and serious causes of chest pain in primary care patients, while avoiding overtesting and overtreating less serious causes.
Hyperventilation syndrome: a frequent cause of chest pain.
Hyperventilation syndrome (HVS) often causes chest pain, and careful history and physical examination can differentiate it from coronary atherosclerotic heart disease (CAHD), avoiding unnecessary coronary angiography.
Case ReportAcute Chest Pain
Acute chest pain should be evaluated urgently and comprehensively to determine the cause and manage it effectively.
Do patients with chronic heart failure have chest pain?
Chronic heart failure patients often report pain, but it is unlikely to be due to angina, even in those with underlying coronary heart disease.
