Pacemaker upgrade study for heart failure
Part of Heart & circulation clinical trials.
This trial is for people with a standard pacemaker that stimulates the right ventricle most of the time. It tests whether a newer type of pacemaker (CRT) can improve heart function and symptoms. If you have a weakened heart (LVEF between 35-50%) and your heart failure has gotten worse, this study may be a good fit.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a pacemaker that paces the right ventricle more than 40% of the time
- Your heart's pumping strength (LVEF) is between 35% and 50%
- Your doctor has recommended upgrading to a special type of pacemaker (CRT) that helps the heart beat more in sync
- You have had at least one sign that your heart failure has worsened since getting the pacemaker, such as a drop in your heart function, an increase in the heart size, higher fluid levels, less activity, or more symptoms

This trial studies a heart pacing approach in people with heart failure symptoms despite preserved heart pumping. It aims to see whether changing heart timing can improve how you feel and how your heart works during exercise.
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 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 if a new pacemaker method (CSP) works better than the standard method (BiVP) for people with heart failure who already have a right ventricular pacemaker and need an upgrade.
This study tests a new way to pace the heart to see if it can improve how well the heart pumps. It uses a special Abbott pacemaker to pace a part of the heart called the left bundle branch and adjust the timing to match your natural heart rhythm.
This trial tests if a newer pacing method called left bundle branch area pacing works as well as standard cardiac resynchronization therapy (CRT) for people with heart failure and a specific heart blockage (left bundle branch block). It aims to offer an effective treatment option with potentially easier setup.
