RT Journal Article SR Electronic A1 Cunningham, Muriel T1 PADIS-PE Identifies Risk Factors for Residual Perfusion Defects After Pulmonary Embolism JF MD Conference Express YR 2015 FD SAGE Publications VO 15 IS 21 SP 10 OP 11 DO 10.1177/1559897715599369 UL http://mdc.sagepub.com/content/15/21/10.abstract AB The PADIS-PE study enrolled patients who had 1 prior episode of unprovoked pulmonary embolism. Analyses of baseline data found that independent risk factors for residual perfusion defect were older age, chronic respiratory disease, and right ventricular dysfunction at diagnosis. Low-molecular-weight heparin reduced the risk for residual perfusion defect.
