A 54-year-old man walked into the clinic complaining of “gas.” For three days he had a burning discomfort in the upper abdomen after meals. He had taken an over-the-counter antacid twice and felt temporary relief.
He denied severe chest pain. No vomiting. No fever. He looked comfortable enough to continue working.
The obvious diagnosis
Dyspepsia seemed reasonable. But during the history, one sentence changed the direction of the consultation:
That was difficult to explain by gastritis alone. He also had diabetes and hypertension.
The clue that mattered
The discomfort was exertional, reproducible and relieved by rest. An ECG was obtained. It showed ischemic changes, and further evaluation supported acute coronary syndrome rather than simple acidity.
The diagnostic twist
Cardiac ischemia does not always present as dramatic central chest pain. Some patients—especially those with diabetes, older adults and women—may describe pressure, indigestion, breathlessness, unusual fatigue or epigastric discomfort.
Clinical pearls
- Ask what triggers the symptom, not only where it is felt.
- Exertional discomfort relieved by rest should raise concern for myocardial ischemia.
- Risk factors change the pre-test probability.
- Do not let temporary response to an antacid “prove” a gastrointestinal diagnosis.
Take-home message
When “gastritis” behaves like angina, treat the pattern—not the label.
