Why the study?
Does two-dimensional speckle-tracking strain echocardiography detect subclinical systolic left ventricular dysfunction better than ejection fraction in long-term heart transplant patients?
Population
31 long-term heart transplant patients (10.6 years post-transplantation) and 42 healthy control subjects.
Comparison
Two-dimensional speckle-tracking strain… vs Healthy control subjects

Strain may detect subclinical LV dysfunction missed by LVEF in transplant recipients; leaves open whether it guides therapy or improves outcomes.
Does two-dimensional speckle-tracking strain echocardiography detect subclinical systolic left ventricular dysfunction better than ejection fraction in long-term heart transplant patients?
Strain analysis by speckle-tracking echocardiography is more sensitive than standard ejection fraction for detecting subclinical systolic dysfunction in long-term heart transplant recipients.
