Flu and Chest Pain: Understanding the Connection
Common Symptoms of Influenza
Influenza, commonly known as the flu, is a viral infection that affects the respiratory system. Typical symptoms include fever, muscle pain, sore throat, coughing, and headaches. Some patients may also experience a burning sensation in the chest and eye pain or sensitivity to light . These symptoms usually resolve within five days, but a lack of energy can persist for several weeks .
Chest Pain and Influenza
Pneumonia as a Complication
One of the most common complications of influenza is pneumonia, which involves inflammation of the terminal airways, alveoli, and lung interstitium. This condition can lead to symptoms such as fever, cough, expectoration, sputum with blood, and chest pain or dyspnea . The presence of chest pain in flu patients is often associated with this secondary bacterial infection or viral pneumonia .
Acute Myocarditis
In rare cases, influenza can lead to acute myocarditis, an inflammation of the heart muscle. This condition can present with severe chest pain and dyspnea, as seen in a case where a patient developed myocarditis following a severe flu episode . The patient exhibited symptoms such as breathlessness, fever, and bilateral wet rales in the lower lung fields, indicating a serious cardiac complication .
Diagnostic and Treatment Guidelines
Identifying Pneumonia
For outpatient adults presenting with acute cough and suspected pneumonia, clinical symptoms such as cough, dyspnea, pleural pain, sweating, fevers, shivers, aches, and a temperature of 38°C or higher are indicative of pneumonia. Chest radiography is recommended to improve diagnostic accuracy 57. The measurement of C-reactive protein levels can further strengthen the diagnosis, although procalcitonin levels do not add significant diagnostic value 57.
Treatment Recommendations
When pneumonia is suspected, empiric antibiotics should be used according to local and national guidelines, especially in settings where imaging cannot be performed 57. For suspected influenza, initiating antiviral treatment within 48 hours of symptom onset can reduce antibiotic use, hospitalization rates, and improve patient outcomes 57.
Conclusion
Chest pain in flu patients can be a sign of serious complications such as pneumonia or acute myocarditis. Recognizing these symptoms early and following appropriate diagnostic and treatment guidelines can significantly improve patient outcomes. Understanding the connection between flu and chest pain is crucial for timely and effective medical intervention.
