Summary
Severe hypercalcemia can mimic a heart attack by causing ST elevation. Prompt correction of high calcium levels resolved the ST elevation, highlighting a rare but critical diagnosis.
Area of Science:
- Cardiology
- Endocrinology
- Internal Medicine
Background:
- Acute myocardial infarction (AMI) is a common emergency diagnosis characterized by ST elevation on electrocardiogram (ECG).
- Differential diagnoses for ST elevation include pericarditis, early repolarization, and hypercalcemia.
Observation:
- A patient presented with chest pain and ST elevation, initially suspected as AMI.
- Coronary angiography showed normal arteries and serum troponin levels were not elevated.
Findings:
- The patient was diagnosed with severe hypercalcemia.
- ST segment elevation resolved completely following correction of hypercalcemia.
Implications:
- This case highlights hypercalcemia as a rare cause of ST elevation mimicking acute myocardial infarction.
- Recognition of this association is crucial for accurate diagnosis and timely management, avoiding unnecessary invasive procedures.
