Correlation of Blood Serum Renalase and Microcirculation Obstruction in Patients with Acute Myocardial Infarction After Primary Percutaneous Coronary Intervention
Trial Parameters
Brief Summary
This research will explore the association between blood serum renalase and microcirculation obstruction in patients with acute myocardial infarction (AMI) after primary percutaneous coronary intervention (PCI). The investigators aim to identify potential risk factors for microcirculation obstruction in AMI patients after PPCI.
