How belly fat affects heart rhythm after bypass surgery
Part of Heart & circulation clinical trials.
This study looks at whether the amount of belly fat (called visceral fat) around your organs affects your chances of developing an irregular heartbeat called atrial fibrillation after heart bypass surgery. If you're having a routine bypass, they'll measure your belly fat with an ultrasound before surgery and then watch your heart rhythm afterward.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 or older.
- You are scheduled for a planned (non-emergency) coronary artery bypass surgery, not an urgent or emergency procedure.
- You are having only the bypass surgery — no other heart procedures at the same time, and it will be done with a heart-lung machine (on-pump).
- You do not have a current cancer diagnosis.
- Your kidney function is not severely reduced (eGFR above 30).
- You do not have advanced COPD (chronic lung disease).
- You do not have atrial fibrillation or flutter before the surgery.
- You are able to have an ultrasound of your abdomen (belly) to measure fat around your organs.

This study looks at whether a certain fat in your blood, called lipoprotein(a), is linked to a heart rhythm problem called atrial fibrillation after heart surgery. You'll wear a special chest band to monitor your heart rhythm, which may help doctors better predict and prevent this complication.
This trial compares two ways of draining fluid after heart bypass surgery to see which one works better. It may help reduce complications like fluid buildup around the heart after your operation.
This study looks at how to predict major heart problems in people with heart failure who are scheduled for bypass surgery (CABG). It aims to improve risk assessment before the procedure.
This study uses an ultrasound test of the heart's right atrium to see if it can predict who will develop an irregular heartbeat (atrial fibrillation) after planned coronary bypass surgery. If you are scheduled for this surgery and have no history of atrial fibrillation, you may be able to join.
This study looks at how often a fast, irregular heartbeat (atrial fibrillation) happens after heart valve or bypass surgery. Knowing this could help doctors take better care of patients after these procedures.
This study watches for an irregular heartbeat called atrial fibrillation that can happen after heart surgery. The aim is to understand and manage this condition better to support recovery.
