PurposeEvaluate the association between chronic right ventricle (RV) dysfunction by transthoracic echocardiogram (TTE) and outcomes in patients with acute pulmonary embolism (PE).MethodsThis was a retrospective analysis of TTE findings in acute PEs. TTEs were used to classify the presence of chronic right ventricular pressure overload (RPVO), defined as RV hypertrophy or RV systolic pressure (RVSP) >50 mmHg, acute RVPO, defined as RV dysfunction not meeting the chronic RVPO definition, or no RV dysfunction. The primary outcome was a composite of death or need for advanced PE therapies at 7 days.ResultsOf 466 patients, 288 had evidence of RV dysfunction. Thirty percent (140) had evidence of chronic RVPO and 148 patients had evidence of acute RVPO. Chronic RVPO patients were older (P = .004), more likely to have COPD, and had lower heart rates and troponin-t values. The acute RVPO patients included more women and were less likely to have a prior PE. There was no difference in outcomes between the acute and chronic RVPO cohorts.ConclusionsChronic RVPO patients had lower heart rates and troponin-t values. Despite these differences there were no differences in need for advanced therapeutic interventions or 7 day mortality.Copyright © 2019. Published by Elsevier Inc.
