SCIENTIFIC LETTER Positive correlation between coronary arterial remodelling and prodromal angina in acute myocardial infarction

R ecently, the relation between coronary arterial remodelling and ischaemic coronary disease has become a focus of investigation. Positive coronary arterial remodelling has been shown to be more frequent in acute coronary syndromes, including acute myocardial infarction (AMI), whereas negative remodelling has been shown to be more frequent in stable angina. However, in the case of AMI, preceding clinical presentations of the onset vary among patients and it is well known that patients often undergo episodes of unstable or stable angina. Furthermore, no studies have correlated remodelling and the presence of prodromal symptoms. In this study intravascular ultrasound (IVUS) was performed before coronary intervention to evaluate the possible correlation between the arterial remodelling at the culprit lesion site of AMI and the prodromal symptoms.
