title: A case of hypothyroidism mimicking acute coronary syndrome.
abstract: Hypothyroid patients have increased concentrations of creatinine kinase that is mostly due to increased CK-MM. However, CK-MB has also been reported to increase above reference values in hypothyroid patients without apparent myocardial damage. This may create confusion during the evaluation of myocardial injury in a hypothyroid patient presenting with chest pain. Troponin I is considered as a superior marker for the diagnosis of myocardial infarction in hypothyroid patients. However, there are some reports showing an increase in the level of troponin I without any myocardial damage in hypothyroid patients as in our case. In this report, we present a 47 years old male hypothyroid patient who had chest pain, abnormal electrocardiographic findings and increased cardiac enzymes suggesting acute coronary syndrome although he had normal coronary arteriogram.
