Heart function test for CRT response prediction
Part of Heart & circulation clinical trials.
This trial uses a special heart ultrasound technique to see how well the heart muscle is working. It aims to predict which patients will benefit from a pacemaker-like device (CRT) for heart failure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be of Han Chinese ethnicity.
- You must be between 18 and 79 years old.
- You must have normal blood pressure, blood sugar, and cholesterol levels.
- You must have normal heart structure and function on ultrasound, with no major valve problems.
- You cannot have serious lung, kidney, liver, or blood diseases, cancer, or autoimmune conditions.
- If you have heart failure, you must have a specific heart rhythm (LBBB) and low pumping ability, or be in one of the other study groups.

This study tests a new heart scan method to help doctors improve pacemaker treatment for people with heart failure. If you already qualify for a special pacemaker called CRT, this scan may make the treatment work better for you.
This trial is testing a new way to use MRI scans to help people with heart failure who need a special pacemaker called a CRT device. It may help doctors better understand how to treat your heart condition.
This trial evaluates a noninvasive way to assess who should get Cardiac Resynchronization Therapy (CRT), and to check results after implantation. If you fit the heart rhythm and heart pump criteria, the approach may help confirm whether CRT is appropriate for you.
This trial tests whether a different pacing approach called left bundle branch pacing can improve outcomes and heart structure changes in people who did not improve with standard biventricular CRT. It may help some patients with ongoing heart failure symptoms and weak heart pumping.
This trial tests a new way to use an ECG (electrical heart recording) to predict who will benefit from a special pacemaker called cardiac resynchronization therapy (CRT). It is for people with heart failure and a specific heart rhythm problem.
This study looks at whether a device called CRT (Cardiac Resynchronization Therapy) can help people with heart failure who have a weak heart pumping strength and a “wide” electrical signal pattern on an ECG. It may help some people feel better and improve heart function, especially if they are not already on the best standard medicines.
