Wearable Technology to Evaluate Hyperglycemia and HRV in DMD
Wearable Technology to Evaluate Hyperglycemia and Heart Rate Variability in Duchenne Muscular Dystrophy

Rövid összefoglaló (regiszter, angolul)
Duchenne muscular dystrophy (DMD) is an X-linked disorder that causes muscle wasting, cardiopulmonary failure, and premature death. Heart failure is a leading cause of death in DMD, but substantial knowledge gaps exist regarding predisposing risk factors. In the general population, hyperglycemia, insulin resistance, and decreased heart rate variability (HRV; reflecting autonomic dysfunction) are associated with cardiomyopathy (CM). It is unclear whether these factors are associated with DMD-CM. Closing this knowledge gap may lead to novel screening and therapeutic strategies to delay progression of DMD-CM, now the leading cause of death in patients with DMD. Despite risk factors for hyperglycemia, including the use of glucocorticoids (GCs), sarcopenia, obesity, and reduced ambulation, little is known regarding glucose abnormalities in DMD. Some of these same risk factors, along with the distance needed to travel for specialty care, present significant barriers to research participation and clinical care for individuals with DMD. Remote wearable technology may improve research participation in this vulnerable population. Therefore, this study will leverage remote wearable technologies to overcome these barriers and define the relationship between dysglycemia and DMD-CM. The goal of this remote study is to evaluate rates of hyperglycemia in individuals with DMD compared to control participants using continuous glucose monitors, and to determine the relationship between hyperglycemia and heart rate variability. Participants will utilize continuous glucose monitors, cardiac monitors, and activity monitors to evaluate glucose levels, heart rate, activity, and sleep.
