Tests coronary blood flow in heart failure patients with CRT
Part of Genetic & congenital, Heart & circulation clinical trials.
This study measures how well blood flows in the heart (coronary flow) in people with heart failure with reduced pumping strength and a specific heart rhythm problem called left bundle branch block. It focuses on people who already have a cardiac resynchronization therapy (CRT) device and have stable treatment, to see how coronary flow relates to their heart condition.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are older than 18 years
- You have heart failure from dilated cardiomyopathy (not from blocked heart arteries)
- You have left bundle branch block (LBBB) and a CRT device
- Your heart recording shows a wide QRS (at least 150 ms) before your CRT was implanted
- You are in normal rhythm (sinus rhythm) and your medicines are stable
- Your kidney function is not too low (eGFR is 30 or higher)

This trial compares two types of pacemaker placement to improve heart function in people with heart failure. One method paces the heart's natural conduction system, while the other paces the lower chambers of the heart. The goal is to find which approach works better for heart resynchronization therapy.
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 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 a pacing approach designed to improve how the heart beats in some people with heart failure and a specific heart rhythm pattern on ECG. If you already need a device (CRT-D) based on your results, the study may help see whether this pacing correction improves outcomes.
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 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.
