Who may be able to join
AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI
Who might be able to join this trial:
- People who are able to give signed and dated consent to take part in the trial
- People who are 18 years of age or older at the time of giving consent
- People whose heart condition meets the guidelines for a treatment called cardiac resynchronisation therapy (CRT), based on specific international cardiology guidelines (confirm with trial site)
- People who have a normal, steady heart rhythm (called sinus rhythm)
- People whose heart's electrical signal takes 130 milliseconds or longer to travel through the heart (a measure called QRS duration)
- People who have a specific heart electrical problem called left bundle branch block
- People whose heart pumps out 35% or less of its blood with each beat (a measure called left ventricular ejection fraction)
- People with heart failure symptoms that are at least moderately limiting to daily life (classified as NYHA Class II or higher)
- People who have been on a stable heart medication plan for at least 6 months
- People who have not had any heart-related procedures or surgeries in the last 6 months
Who may not be able to join:
- People with a history of long-lasting or permanent irregular heart rhythm in the upper chambers of the heart (atrial fibrillation)
- People who already have a pacemaker or an implanted heart defibrillator (ICD)
- People who need a pacemaker because their heart beats too slowly
- People whose doctors are considering a specific type of pacemaker placement involving the heart's natural electrical pathway (His bundle or cardiac conduction pacing)
- People who have unstable chest pain (unstable angina)
- People who have had a heart attack within the last 40 days before joining the trial
- People who have had open-heart bypass surgery or heart valve surgery within the last 90 days before joining the trial
- People who have already had a heart transplant, are currently on a waiting list for one, or are likely to need one within the next year
- People who have a mechanical device already implanted to help the left side of their heart pump (a left ventricular assist device)
- People who are currently receiving continuous drip-based medication through a drip to help their heart pump
- People with severe narrowing of the heart's aortic valve (valve opening less than 1.0 cm², or valve surgery expected during the study period)
- People born with a structural heart defect (congenital heart disease)
- People who have an artificial mechanical valve on the right side of their heart
- People whose treating doctor believes they have less than one year to live
- Women who are pregnant, breastfeeding, or of childbearing age and not using a reliable form of contraception
- People who are already participating in another clinical study that could affect the results of this trial
- People who are unable to have a CT scan for medical reasons
- People with chronic kidney disease where a specific kidney function measure (eGFR, calculated using a standard formula) is below 40 ml/min/1.73m²
