Simple tube change could cut Post-Surgery heart flutter by 30%

This study tests whether keeping a special chest tube in place for up to 3 days after heart surgery can lower the chance of developing a fast, irregular heartbeat called atrial fibrillation. About 624 adults having routine heart surgery will be randomly assigned to get the tube plus standard care, or standard care alone. The goal is to see if this simple method safely reduces heart rhythm problems and helps people recover faster.
