Abstract
Pulmonary embolism (PE) is a clinical phenomenon presenting with a spectrum of findings, ranging from small emboli causing mild hemodynamic dysfunction to massive emboli leading to cardiogenic shock, and it can sometimes be fatal.(70) Due to pulmonary bed obstruction, PE can result in acute right ventricular dysfunction (RVD) which is a life-threatening condition. Because most patients ultimately die within the first hours of presentation, early diagnosis is of paramount importance. The aim of this study was to assess the association of CHA2DS2-VASc Score with the PE severity, RVD and the in-hospital mortality in patients presented with acute PE. The present study was conducted on 50 patients admitted with acute PE at cardiovascular medicine department at Tanta University Hospitals within 6 months from June 2019 to December 2019. We studied the association of different variables including demographic data, common risk factors, clinical presentation, management and the in-hospital mortality with the PE clinical subgroups (massive, sub-massive and non-massive) based on the severity of clinical presentation. Then, we studied the association of these variables with the thromboembolic risk based on the CHA2DS2-VASc scores calculated for all patients. And finally, we investigated the predictors of the RVD using univariate and multivariate analyses.
