Predicting heart weakness risk in pacemaker patients

The PACEVALUE study is tracking thousands of patients who receive heart devices—like pacemakers, defibrillators, or specialized pacing devices—to understand who is at risk of developing a complication called pacing-induced cardiomyopathy, where the heart's pumping ability weakens over time. By collecting information from routine medical visits, device data, and patient experiences, researchers hope to create a risk prediction tool that helps doctors choose the best pacing strategy for each individual before surgery.

While these heart devices save lives, long-term pacing can sometimes weaken the heart muscle, leading to more hospitalizations and serious complications. This study exists to predict which patients are at highest risk and test whether personalized pacing approaches—including newer techniques—can prevent this problem and improve outcomes.
