Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a multi-center prospective cohort study of patients with first-episode deep venous thrombosis and pulmonary embolism.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Subjects will be identified from the clinical setting and approached to participate in this observational study where participants will be enrolled at 3 different sites and referred from several more sites and have: cardiopulmonary exercise testing and pulmonary function testing at The Institute of Exercise and Environmental Medicine (IEEM), UTSW Exercise Facility, Cardiac MRI and MRI for pulmonary perfusion at Children's Medical Center and MR Spectroscopy and MR for Muscle Perfusion at the Advanced Imaging Research Center (AIRC) performed in Dallas over a 3 day research visit at week 12 and Month 12. Blood is collected for biomarkers at these visits and multiple questionnaires are completed by participants.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Participants with Pulmonary Embolism

The target accrual is based on the primary endpoint (exercise intolerance and dyspnea on exertion). To achieve adequate power and precision in the primary analysis, the target enrollment is 80 children. Both males and females of all races and ethnic groups are eligible for this study.

Blood draw (Visit 1)

Intervention Type DIAGNOSTIC_TEST

Labs will be drawn at Visit 1, also referred to as screening (within 60 days of diagnosis) with the standard of care labs drawn.

Blood draw (Visits 2 and 3)

Intervention Type DIAGNOSTIC_TEST

Labs will be drawn at Visit 2 (12 weeks post-diagnosis with a range of 10-16 weeks) and Visit 3 (12 months ± 30 days) for research purposes only and will be collected at Children's Medical Center and processed at UT Southwestern Medical Center.

Control Group

A positive control group that has not had pulmonary embolism (PE) but is prescribed physical activity restrictions expected to produce a similar deconditioning effect as patients with PE will be enrolled from UT Southwestern only (cohort 1) or children who are no prescribed physical activity restrictions and are otherwise considered healthy (cohort 2). The target accrual of the positive control group is based on feasibility and availability of funds and will be limited to 25 controls.

Blood draw (Visits 2 and 3)

Intervention Type DIAGNOSTIC_TEST

Labs will be drawn at Visit 2 (12 weeks post-diagnosis with a range of 10-16 weeks) and Visit 3 (12 months ± 30 days) for research purposes only and will be collected at Children's Medical Center and processed at UT Southwestern Medical Center.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Ages 8 to ≤ 21 years
* Participant must be able to speak and understand English
* Be willing to participate and able to comply with the study protocol
* For participants with PE: Children with acute, radiologically confirmed pulmonary embolism (PE) with our without DVT
* For control group: Cohort 1: Children who are prescribed physical activity restrictions for 2 up to 12 weeks following any minor outpatient surgery or, minor injury (surgery or injury is referred to as "diagnosis" hereafter) Cohort 2: Children who are not prescribed physical activity restrictions and are otherwise considered to be healthy.

Exclusion Criteria

* Congenital heart disease with abnormal pulmonary circulation or with in-situ pulmonary artery thrombosis
* Chronic kidney disease
* Chronic inflammatory or an autoimmune disorder (such as systemic lupus erythematosus, juvenile rheumatoid disorder, inflammatory bowel disease, and sickle cell disease)
* A metabolic or endocrinological disorder such as diabetes mellitus or thyroid disorder
* History of or active cancer
* Pregnant
* Musculoskeletal limitations to exercise expected to be present uptil 4 months post-diagnosis
* Weight ≥ 300 lbs
* Contraindications to magnetic resonance imaging
* Frequent severe exacerbations of asthma defined by two or more bursts of systemic glucocorticoids (more than three days each) in the previous year or at least one hospitalization, intensive care unit stay or mechanical ventilation in the previous year. Patients should also be excluded if there are daily symptoms of asthma requiring daily use of short-acting bronchodilators such as albuterol or levalbuterol administration. The use of controller medications such as daily inhaled corticosteroids for mild persistent asthma is not exclusionary.
* Has any other medical condition, which in the opinion of the investigator may potentially compromise the safety or compliance of the patient or may preclude the patient's successful completion of the clinical study


* Lack of anticoagulant treatment for the acute VTE due to contraindications
