  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study

The purpose of this study is to determine whether changes in the following parameters of cardiac function with low intensity exercise occur following anthracycline therapy:

  • 2D and 3D left ventricular (LV) longitudinal strain and strain rate
  • Right ventricular (RV) longitudinal strain and strain rate
  • LV circumferential and radial strain and strain rate
  • 2D and 3D wall motion
  • 2D and 3D volumetric LVEF
  • Mitral valve inflow velocities (E, A) and mitral annular tissue Doppler (e’, a’)
  • Tricuspid tissue velocities and TAPSE

The study will also determine whether changes after chemotherapy in any of the aforementioned parameters of cardiac function with low intensity exercise:

  • Occur before changes in resting strain or resting LVEF
  • Predict future reductions in LVEF (cardiotoxicity)
  • Predict the development of clinical heart failure


Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
