Usefulness of myocardial strain imaging in Duchenne muscular dystrophy.
Duchenne muscular dystrophy is an X-linked recessive disorder caused by the absence of dystrophin. Heart involvement is a classical complication in this disease and leads progressively to heart failure. Detecting latent myocardial involvement is essential in this disease because early use of drugs like angiotensin-converting enzyme inhibitors may delay the progression of heart disease. Myocardial strain imaging is an application of the tissue Doppler imaging. By assessing regional myocardial function, this tool might help clinicians to detect latent myocardial involvement in DMD patients.
