Recurrent ST Elevation Myocardial Infarction: What is the Aetiology?

Coronary artery disease is a leading cause of morbidity and mortality in the western world. Plaque rupture in an atherosclerotic lesion is the most commonly encountered underlying pathophysiology. Spontaneous coronary dissection can have similar presentation, but we as a community of cardiologists may not be aware of uncommon aetiologies, such as vasculitis presenting as ST elevation myocardial infarction (STEMI). Here we present a case report of a lady, who presented with STEMI on three occasions within five days, due to underlying granulomotosis with polyangiitis (GPA).
