Postoperative atrial fibrillation (POAF) is associated with increased mortality and morbidity in patients undergoing isolated coronary artery bypass grafting (CABG). It has been estimated that 5-40% of CABG patients experience POAF. Advanced age, P wave abnormalities, left atrial dilation, emergency surgery, low left ventricle ejection fraction, low glomerular filtration rate and chronic obstructive pulmonary disease have been reported in the etiology. Predicting which patients would experience POAF following CABG is important since it would allow physicians to apply more focused prophylactic measures. Lactate is the final product of anaerobic glycolysis. Serum lactate level are increased in case of inadequate oxygen delivery to tissues. The investigators aim to assess whether serum lactate levels measured early in the postoperative period could be used as a predictive marker of POAF in adults undergoing isolated CABG.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
