Abstract

<abstract abstract-type="main" id="jth12989-abs-0001"> <title>Summary</title> <sec id="jth12989-sec-0001" sec-type="section"> <title>Background</title> <p>Exercise training after myocardial infarction is the standard of care within a cardiac rehabilitation setting. However, there is scant evidence regarding the safety and efficacy of early exercise training following a venous thromboembolism (VTE).</p> </sec> <sec id="jth12989-sec-0002" sec-type="section"> <title>Methods</title> <p>Eligible consenting participants were randomly allocated, on an individual basis, to either a 3‐month exercise and behavioral weight loss intervention group or a control group. The primary clinical outcomes were change in health behavior (body weight and physical activity) and objectively measured fitness (<italic>V</italic><sc>o</sc><sub>2peak</sub>).</p> </sec> <sec id="jth12989-sec-0003" sec-type="section"> <title>Results</title> <p>From 2013 to 2014, 239 patients presented to a community‐based specialty clinic after an acute VTE; 43 (18%) of these met the eligibility criteria for inclusion in the study. Of these, 19 (44%) consented to participate (nine in the intervention group; 10 in the control group). There were no adverse events in either group over a 3‐month period. The mean difference in body weight between the intervention and control groups was − 4.6 kg (95% confidence interval [CI] − 11.4 to 2.2) in favor of the intervention. The mean difference in duration of physical activity from baseline to 3 months between the intervention and control groups was 133 min (95% CI 7–248) in favor of the intervention. There was a significant change in fitness over a 3‐month period for the intervention group (baseline <italic>V</italic><sc>o</sc><sub>2peak</sub>, 26.1 ± 5.4 mL O<sub>2</sub> kg<sup>–1</sup> min<sup>–1</sup>; postintervention <italic>V</italic><sc>o</sc><sub>2peak</sub>, 29.8 ± 5.4 mL O<sub>2</sub> kg<sup>–1</sup> min<sup>–1</sup>).</p> </sec> <sec id="jth12989-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Early initiation of exercise training resulted in improvements in physical activity and fitness, and did not result in adverse events while individuals were receiving therapeutic anticoagulation. These are the first data on initiation of an exercise training and behavioral weight loss program in the early post‐VTE setting.</p> </sec> </abstract>
