Comparing two ways to measure heart function in heart failure patients

This research study is testing whether a newer three-dimensional ultrasound technique can better measure heart function than the standard two-dimensional ultrasound that doctors currently use. Researchers want to understand how these two imaging methods compare in patients with heart failure, and which one might be more helpful for predicting how patients will do over time.

Currently, doctors use a standard two-dimensional ultrasound to measure how well the heart is working in heart failure patients. However, a newer three-dimensional ultrasound technique may provide a more complete picture of heart function, but doctors need to understand how the two methods compare and whether the new technique gives better information for patient care.
