Hypercalcemia mimicking acute coronary syndrome

Abstract

We described 2 patients (28-year-old and 69-year-old females) with hypercalcemia (4.47 mmol/L and 4.8 mmol/L), chest painand electrocardiogram with ST-T segment changes mimicking acute coronary syndrome. One patient presented ST segment elevation in right precordial leads V1–V3 max. 4 mm, the second one presented negative T waves in V1–V6 leads. Troponin level was normal in both cases. Additionally, corrected QT apex was shortened in both cases, 250 ms and 206 ms respectively and T wave humps in lateral leads was observed.
