Chest Pain Radiating to Back: Key Causes and Clinical Features
Aortic Dissection and Intramural Hematoma
Sudden, severe chest pain radiating to the back is a classic symptom of aortic dissection, a life-threatening condition that requires urgent attention. This pain is often described as tearing or sharp and may be accompanied by neurological symptoms, pulse deficits, or syncope. Aortic dissection is more common in men, especially those aged 55-65, and is associated with risk factors such as hypertension and smoking. Diagnostic imaging, such as CT scans, is crucial for confirmation, as initial blood tests and ECGs may be normal. Intramural hematoma, a related aortic emergency, can present similarly and also requires prompt surgical intervention 1234610.
Acute Coronary Syndrome and Myocardial Infarction
Chest pain radiating to the back can also be a sign of acute coronary syndrome (ACS), particularly when the pain is severe, occurs at rest, and is associated with sweating or a sensation of tightness. While ACS more commonly presents with pain radiating to the left arm or jaw, back radiation is not uncommon and should raise suspicion, especially in patients with risk factors like smoking or a history of heart disease. Women may be more likely to experience back pain as a manifestation of coronary artery disease compared to men 89.
Myocarditis
Myocarditis, including cases associated with COVID-19 vaccination, can present with sudden chest pain radiating to the back. Diagnosis is supported by elevated cardiac enzymes, imaging findings on cardiac MRI, and exclusion of other causes such as aortic dissection or coronary artery disease .
Other Causes: Diaphragmatic Hernia
Less commonly, chest pain radiating to the back may be due to non-cardiac causes such as a diaphragmatic (Bochdalek) hernia. In these cases, imaging reveals herniation of abdominal contents into the thoracic cavity, and pain may resolve after appropriate surgical intervention .
Clinical Assessment and Diagnostic Approach
When evaluating chest pain radiating to the back, clinicians should consider aortic dissection, ACS, myocarditis, and other less common causes. Key features that increase suspicion for aortic dissection include sudden onset, severe intensity, tearing quality, neurological symptoms, and pulse deficits. For ACS, pain that escalates, occurs at rest, and is not relieved by nitroglycerin is concerning. Imaging studies such as CT angiography, echocardiography, and cardiac MRI are essential for accurate diagnosis 123467810.
Conclusion
Chest pain radiating to the back is a symptom that warrants immediate and thorough evaluation due to its association with life-threatening conditions like aortic dissection and acute coronary syndrome. Prompt recognition, risk factor assessment, and appropriate imaging are critical for timely diagnosis and management 12346789+1 MORE.
