ClinConnect Summary

This clinical trial is investigating new treatment options for patients who have heart failure with preserved function (HFpEF) and also experience atrial fibrillation (AF), a common heart rhythm problem. The study will explore how effective rhythm control therapies, like catheter ablation and antiarrhythmic medications, can be in managing both conditions together. The researchers aim to see if combining these treatments with optimized heart failure therapies can improve patient outcomes. This trial is important because many existing treatments for AF have not been tested specifically in patients with HFpEF, which affects about 43% of these patients.

To be eligible for the trial, participants should be at least 50 years old and have symptoms of heart failure along with paroxysmal (intermittent) or persistent atrial fibrillation. They also need to be on heart failure medications for at least 30 days before joining the study. Participants will receive careful monitoring and treatment during the trial, and they will need to provide written consent to take part. This study is currently recruiting, and if you or a loved one meet the criteria, it could be a chance to access new treatment options while contributing to important medical research.
