Prognostic value of pericardial effusion in patients with STEMI treated with a pharmacoinvasive or a primary percutaneous intervention: From an experience of a tertiary center

Abstract Background: The long-term prognostic relevance of pericardial effusion (PE) in ST-segment elevation myocardial infarction (STEMI) patients treated with a pharmacoinvasive or a primary percutaneous intervention (PCI ) strategy are not well established. The aim of this study was to investigate the prognostic impact of pericardial effusion in these patients.Methods: A total of 860 STEMI patients underwent a pharmacoinvasive or a primary PCI strategy were enrolled in this study. Echocardiographic, demographic, and laboratory data were collected. All-cause mortality was the primary end-point.Results: PE was present in 51 patients (5.9%). The patients with PE was higher long-term mortality rate compared with those did not (41% vs 27%, p = 0.0025). However, both multivarite analysis (HR:1.243, 95%CI: 0.765-2.022, p = 0.380) and propencity matching scores (40% vs 28%, p = 0.205) showed that there was no relationship between PE and long-term mortality.Conclusion: The presence of PE was not independent predictor of long-term mortality in STEMI patients treated with a pharmacoinvasive or a PCI.
