Some studies suggest that patients with acute myocardial infarction (AMI) and preinfarction angina (PA) had smaller infarction size, better clinical outcome, less readmission and less mortality. However, the relationship between preinfarction angina and no-reflow has not yet been well investigated.1-3 We hypothesized that patients with PA have a reduced no-reflow and better left ventricular function recovery after revascularization. The present study was aimed to evaluate myocardial perfusion after revascularization in patients with or without PA by using intravenous myocardial contrast echocardiography (MCE).
