A new exercise plan aims to get pulmonary embolism survivors back on their feet

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: Acute intermediate-risk PE, defined as: * Intraluminal filling defect in segmental or larger vessels on computed tomography pulmonary angiography or high-probability ventilation/perfusion scan AND * Evidence of right ventricular enlargement by computed tomography (RV to LV ratio \>1) or echocardiography; and/or right ventricular dysfunction by transthoracic echocardiography. These imaging characteristics must be in the setting of acute PE rather than explained by a prior chronic condition. Acute high-risk PE, defined as: * Intraluminal filling defect in segmental or larger vessels on computed tomography pulmonary angiography or high-probability ventilation/perfusion scan AND * Evidence of right ventricular enlargement by computed tomography (RV to LV ratio \>1) or echocardiography; and/or right ventricular dysfunction by transthoracic echocardiography. These imaging characteristics must be in the setting of acute PE rather than explained by a prior chronic condition; AND * Hypotension (systolic blood pressure \< 90 mm Hg sustained for more than 15 minutes; or requiring vasopressors) or cardiogenic shock due to acute pulmonary embolism. Exclusion Criteria: * Inability to ambulate independently, which is necessary to perform 6MWD (may be self-reported or as deemed by physical therapy during inpatient evaluation). * If patient requires supplemental oxygen during ambulation, this does not exclude patient from participation and will be noted during eCRF. * Prior history of pulmonary embolism * History of CTEPH or pulmonary arterial hypertension * Unable to read a questionnaire in English * Unable to return for baseline, 3- or 6-month follow-up visit * Pregnancy-associated pulmonary embolism * Life expectancy \<1 year based on comorbidities * Unable/unwilling to provide informed written consent
