Differential effects of PDE5 inhibitors on cardiac dysfunction in the MDX ouse model of Duchenne muscular dystrophy

In its later stages DMD leads to dilated cardiomyopathy and heart failure with high level of mortality. At present there are no effective treatments for most of the cardiac pathology in DMD patients.
