Which test is crucial to assess for complications in Duchenne muscular dystrophy?

In the context of Duchenne muscular dystrophy (DMD), cardiac echocardiography is crucial for assessing potential complications, particularly those related to cardiac function. DMD is a progressive muscle degeneration disorder that affects not only skeletal muscles but also the cardiac muscles over time. Children with DMD are at significant risk for developing cardiomyopathy, which can manifest as heart failure or arrhythmias.

By using echocardiography, clinicians can evaluate the structural and functional aspects of the heart, including left ventricular function and any dilatation or other abnormalities that may indicate cardiomyopathy. Early detection of cardiac complications is essential for timely management, including potential interventions such as medications or monitoring strategies to improve outcomes.

While other tests such as pulmonary function tests are also important for assessing respiratory function in DMD, they do not specifically focus on cardiac complications, which exacerbates morbidity in these patients. Genetic testing is crucial for diagnosis but does not provide information on ongoing complications. Therefore, cardiac echocardiography is indispensable in monitoring and managing the cardiac risks associated with Duchenne muscular dystrophy.
