Why the study?
Does cigarette smoking increase atrial fibrosis and the risk of postoperative atrial fibrillation in patients undergoing CABG?
Does cigarette smoking increase atrial fibrosis and the risk of postoperative atrial fibrillation in patients undergoing CABG?
Cigarette smoking contributes to the development of atrial fibrosis via nicotine, providing an arrhythmogenic substrate that may increase the likelihood of postoperative atrial fibrillation.
