Percutaneous coronary intervention (PCI) can effectively restore myocardial perfusion in patients with ST-segment elevation myocardial infarction (STEMI). Nevertheless, STEMI patients may still experience a "no-reflow" phenomenon after PCI. Accordingly, this study focused on the clinical value of low-dose dobutamine stress myocardial contrast echocardiography (MCE) for evaluating myocardial microcirculation perfusion and long-term prognosis in STEMI patients after PCI.
