Subclinical involvement of the heart and its associated factors in patients with sarcoidosis with normal systolic function using 2D speckle tracking.

The marked changes in the 2D speckle-tracking parameters in patients with extra-cardiac sarcoidosis can be of great value in the prediction of cardiac involvement. The occurrence of the abovementioned cardiac changes can be completely independent of the involvement of left ventricular function and is therefore predictable in patients with normal ventricular function.
