Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Body weight is a key modifiable risk factor driving risk of incident and recurrent VTE. Obese patients with prior VTE have a 2-fold higher risk of a second VTE compared to normal weight patients.(1) Importantly, VTE recurrence risk escalates if weight control is not established. Weight gain after acute DVT is common, with a mean 7% increase over 6 months.(2) To date, however, there is limited evidence regarding whether early initiation of exercise training following acute DVT is safe and feasible and mitigates weight gain associated with a VTE diagnosis. Previously, a significant decrease in body weight and fat mass loss was demonstrated utilizing high-caloric expenditure exercise in the CR setting.(3) Delineating the impact of high-caloric expenditure exercise to induce weight loss and reduce VTE complications and recurrence is a critical first step toward evaluating the role of early post-VTE rehabilitation in the clinical setting.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
VTE REHABILITATION
The exercise prescription emphasizes gradual progression to longer duration (45-60 minutes per session), lower intensity (60-70% peak heart rate (PHR) exercise. Subjects have an exercise expenditure goal of \>3000 kcal/wk, attained after 2 to 4 weeks of gradually lengthening exercise bouts. All exercise sessions will be performed onsite for the first two weeks, after which subjects will perform 2 additional sessions a week in the home environment. Exercise logs will be reviewed weekly.
The Dietary Behavioral Weight Loss Intervention(BWL) intervention consists primarily of 12 small group sessions led by a dietician emphasizing dietary records, itemization of food, and caloric content. Subjects will be given individualized daily caloric goals 500 kcal less than predicted maintenance calories based on their baseline body weight.
VTE REHABILITATION: High-Caloric Expenditure Exercise Training (HCE) and The Dietary Behavioral Weight Loss Intervention (BWL)
CONTROL
The 12-week program will consist of monthly phone contacts to check-in to capture physical activity done outside of the intervention setting.
