Traditional echocardiographic parameters, STV, and regional wall motion abnormalities (RWMA) were compared.

The NIDCM group had a significantly higher mean STV compared to the ICM group. An STV threshold of 0.768 provided a sensitivity of 86.0% and a specificity of 94.8% for distinguishing ICM from NIDCM.
