Children and Adolescents With Marfan Syndrome: 10,000 Healthy Steps and Beyond

Marfan Syndrome Clinical Trial

Official title: Children and Adolescents With Marfan Syndrome: 10,000 Healthy Steps and Beyond

Status Completed

Clinical Trial Summary

Marfan patients are at risk of sudden death due to weakening of the wall of the large blood vessel leading from the heart (aorta). The wall of the aorta weakens and dilates which can rupture, leading to death, and sometimes during intense exercise.

There is some evidence in Marfan patients that a stiffer aorta increases risk for rupture.

For some time, clinical care has focused on what type of exercise these patients should avoid due to risk for aortic dissection. Little clinical emphasis has been placed on encouraging patients to engage in routine and safe exercise such as walking. Informed by this evidence, the investigators propose to collaboratively investigate whether regular exercise improves aortic health in adolescent Marfan patients.

Clinical Trial Description

Marfan syndrome is an inherited disorder of the connective tissue, which provides material and support for the skeleton, muscles, and blood vessels. Marfan patients are at risk of sudden death due to weakening of the wall of the large blood vessel leading from the heart (aorta). The wall of the aorta weakens and dilates which can rupture, leading to death, and sometimes during intense exercise.

Typically, the weakening process starts when elastin fibers in the aorta become fragmented. There is some evidence in Marfan patients that a stiffer aorta increases risk for rupture.

For some time, clinical care has focused on what type of exercise these patients should avoid due to risk for aortic dissection. Little clinical emphasis has been placed on encouraging patients to engage in routine and safe exercise such as walking. These young patients also frequently choose sedentary lifestyles, most likely due to limitations imposed by parents as well as adolescents' own perceptions of what is safe for them and their physical capabilities. Another complicating factor is that these patients often experience difficulty coping with their diagnosis. Informed by this evidence, the investigators propose to collaboratively investigate whether regular exercise improves aortic health and coping skills in adolescent Marfan patients. ;
