Is a superficial burning sensation across the upper chest just above the sternum and near the lower clavicle likely cardiac in origin?

A superficial burning sensation across the upper chest is less likely to be cardiac in origin, but cardiac causes cannot be excluded based on symptom quality alone.

The description of "burning" and "superficial" sensation argues against cardiac ischemia, but the location (upper chest, above sternum, near clavicles) and the inability to definitively rule out cardiac disease based on symptoms alone means this requires proper cardiac evaluation.

Why This Is Probably Not Cardiac

According to the 2021 AHA/ACC/CHEST Guidelines, myocardial ischemia characteristically produces deep, difficult to localize, and diffuse visceral discomfort 1. The key distinguishing features are:

• Cardiac pain is deep, not superficial - The guideline explicitly states that ischemic discomfort is "characteristically deep" 1
• Point tenderness renders ischemia less likely - If she can localize it to a superficial area, this argues against cardiac origin 1
• Burning quality alone is not diagnostic - While burning can occur with cardiac ischemia, the superficial nature is atypical

Critical Caveat: Don't Be Falsely Reassured

However, the guidelines strongly emphasize that "what appears to be noncardiac chest pain may be ischemic in origin" 1. This is a crucial pitfall to avoid. The 2021 guidelines explicitly recommend:

• Never use the term "atypical" chest pain because it leads to misclassification as benign 1
• Instead, classify as "cardiac," "possibly cardiac," or "noncardiac" 1
• Women are at particular risk for underdiagnosis and often present with accompanying symptoms beyond classic chest pain 1

What You Must Do Next

The guideline mandates an initial assessment to triage based on likelihood of myocardial ischemia (Class 1, Level B-NR recommendation) 1. This requires evaluating:

1. Duration and onset pattern - Gradual buildup over minutes suggests angina; fleeting seconds argues against it 1
2. Precipitating factors - Exercise or emotional stress triggering symptoms increases cardiac likelihood 1
3. Relieving factors - Though nitroglycerin relief is NOT diagnostic 1
4. Associated symptoms - Dyspnea, diaphoresis, nausea, jaw/neck pain, especially in women 1
5. Cardiac risk factors - Age, hypertension, diabetes, family history 1

The Bottom Line Algorithm

Based on the superficial burning quality described:

• Classify this as "possibly cardiac" rather than definitively noncardiac 1
• Obtain ECG and cardiac biomarkers to exclude acute coronary syndrome 2
• If these are negative and risk factors are low, consider gastroesophageal reflux disease as the most common cause of noncardiac chest pain 3, 4, 5
• A high-dose PPI trial can confirm GERD-related chest pain 5

Only 5.1% of ED chest pain patients have acute coronary syndrome, but missing it has grave consequences 1. The superficial burning quality makes cardiac origin less likely, but proper cardiac evaluation is mandatory before attributing symptoms to a benign cause.
