Coffee, activity, and heart rhythm in defibrillator patients
Part of Heart & circulation clinical trials.
This study looks at whether drinking coffee and being physically active affect dangerous heart rhythms in people who have heart failure and a defibrillator. If you join, you'd answer questions about your coffee intake, and the study will use your defibrillator's data to track your heart rhythms.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older.
- You have a type of heart failure where your heart's pumping strength is reduced (ejection fraction below 50%).
- You have a defibrillator (ICD) that is placed in a vein and has been in place for at least 12 months.
- You are able to answer a questionnaire about your coffee and caffeine intake.
- You must not have certain rare heart rhythm conditions (channelopathies) or a subcutaneous defibrillator.

This study looks at how to better track patients’ quality of life (how you feel and function) after catheter ablation for a dangerous heart rhythm, using questionnaires you complete. It may help the care team understand how to measure patient outcomes more accurately after treatment.
This study looks at how the heart's electrical signals can help doctors understand if treatments prevent dangerous heart rhythms in active people. It involves people with or without heart devices like ICDs or pacemakers, and may help improve care for active individuals with heart conditions.
This study collects detailed ECG data and feedback from people with heart failure to better understand the condition and improve care. It involves noninvasive monitoring and a discussion of your symptoms and daily life.
This study looks at how coffee affects heart health and blood vessel function. It compares drinking regular coffee with decaffeinated coffee to see if caffeine has a different effect. If you join, you'll get free coffee drinks and help researchers learn more about how coffee affects the body.
This trial tests whether stopping caffeine for up to two months helps control heart rate in people with permanent atrial fibrillation. If you drink at least one cup of caffeinated coffee a day, you may be able to join and help find out if giving up caffeine improves your heart rate.
This study looks at how caffeine given through an IV affects the heart's electrical signals during a procedure to treat atrial fibrillation. It may help doctors understand if caffeine can trigger irregular heartbeats.
