The case of a 25-year-old woman presenting with chest pain,
ECG changes, and laboratory findings suggestive of myocardial
infarction is reported. Cardiac catheterization showed impaired
left ventricular performance but otherwise normal coronary
arteries. Laboratory analyses revealed primary
hypoparathyroidism, and supplementation with calcium and vitamin
D3 was initiated. There was subsequent improvement in
laboratory findings as well as echocardiographically determined left
ventricular performance. Thereafter, the patient remained asymptomatic.
Apart from some persisting ECG repolarization disturbances, there
was complete normalization of the initial changes. This case
demonstrates a combination of clinical, blood biochemical, and ECG
findings mimicking acute myocardial infarction.
