During a mean period of 27 months of follow-up, the major adverse cardiovascular and cerebrovascular events (MACCE) were recorded.Results: The incidence of LVT (n = 47) was 3.60%. The independent risk factors of LVT included anterior STEMI, left ventricular (LV) aneurysm, reduced LV ejection fraction (LVEF), dilated LV end-diastolic dimension (LVEDD), and delayed door-to-balloon time (DTBT). During follow-up, LVT was an independent risk factor for MACCE [hazard ratio (HR)=3.46; 95% confidence interval (CI) = 2.23– 3.38; P 0.05).Conclusion: In the era of PPCI, the presence of early LVT following STEMI was associated with adverse events. Furthermore, the prognosis of patients with LVT did not improve even if the LVT regressed. LVT was likely a generalized indicator of impaired cardiac performance, rather than the cause. This indicated that prophylactic therapy and identifying individuals with a high risk of developing LVT were of substantial importance.Keywords: left ventricular thrombus, ST-segment elevation myocardial infarction, prognosis, risk factors
