Abstract:
Duchenne muscular dystrophy (DMD) is a neuromuscular disease characterized by a progressive skeletal muscular weakness. As the respiratory care of such patients has been dramatically improved during the past few years, the DMD associated cardiomyopathy is becoming a new concern. We report a clinical case of a Troponin I level increase with normal coronarography occurring after an acute episode of respiratory failure. This report suggests the sensitivity of cardiomyocytes to hypoxemia in DMD patients.

Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
