Hypertrophic cardiomyopathy mimicking inferior wall myocardial infarction
Keywords:Hypertrophic cardiomyopathy, Myocardial infarction, Cardiac biomarker
Electrocardiogram is most often the first-hand diagnostic tool with a cardiologist. Promptly identifying life threatening arrhythmias and myocardial infarction with ECG saves many lives. Quite often the electrocardiogram may have dubious findings and further testing helps arriving at the right diagnosis. Herein, we present a case of hypertrophic cardiomyopathy where the ECG mimicked inferior wall myocardial infarction along with a raised high sensitive Troponin T (hsTnT). A coronary angiogram failed to reveal any acute or chronic obstructive lesion in the coronary arteries. We discussed the varied ECG patterns in hypertrophic cardiomyopathy and causes of troponin elevation apart from myocardial infarction. We also discussed other causes of ‘pseudo-infarct’ pattern on ECG. This provides insight into a more comprehensive approach in management of each patient.
