Brief Summary

Reperfusion therapy for acute ST segment elevation myocardial infarction (STEMI) can significantly reduce mortality, but patients may still have heart failure and adverse cardiovascular events due to massive myocardial loss. About 20% of patients present with acute heart failure (AHF) at admission, It is the most important cause of hospital death in acute myocardial infarction. Because of the large necrotic area of acute anterior myocardial infarction, heart failure still occurs in a considerable number of patients even after revascularization (PCI). Myocardial protection of ischemic myocardium is a hot topic in clinical research.

Both ESC and Chinese heart failure guidelines recommend levosimendan for the treatment of acute decompensated heart failure. A large number of studies have proved that levosimendan can significantly reduce myocardial injury and improve cardiac function in patients with acute STEMI complicated with left ventricular dysfunction and cardiogenic shock compared with placebo. Basic research has confirmed that levosimendan can reduce the myocardial infarction area after acute coronary occlusion, improve the left ventricular function, and exert the effects of anti myocardial ischemia, myocardial injury, myocardial fibrosis, ventricular remodeling and anti apoptosis. However, there is still a lack of early preventive application of levosimendan in acute anterior myocardial infarction after PCI to improve ventricular remodeling and reduce the incidence of heart failure.

The purpose of this study was to investigate the effect of early prophylactic levosimendan on left ventricular remodeling, ischemic myocardial protection and the development of heart failure in patients with acute anterior myocardial infarction after PCI.
