Insights
Atrial fibrillation (AF) is common after coronary artery bypass graft (CABG) surgery. This study found AF/flutter occurred more in males aged 60-69, with no other significant predisposing factors identified.
Area of Science:
- Cardiology
- Cardiac Surgery
- Electrophysiology
Background:
- Atrial fibrillation (AF) is a frequent complication post-coronary artery bypass graft (CABG) surgery, affecting 10-60% of patients.
- AF can lead to adverse outcomes, including increased healthcare costs, morbidity, and mortality.
- Identifying predisposing factors for AF post-CABG is crucial for patient management.
Purpose of the Study:
- To investigate potential predisposing factors for atrial fibrillation (AF) and flutter following coronary artery bypass graft (CABG) surgery.
- To compare clinical and demographic data between patients who developed AF/flutter and a control group.
Main Methods:
- Retrospective review of 143 patient records with AF/flutter post-CABG and 39 control patients.
- Data collected included time of onset, weight gain, fluid status, hematocrit, and drug regimens.
- Statistical comparison of these factors between the AF/flutter and control groups.
Main Results:
- No significant differences were observed in weight gain, fluid status, or hematocrit between the groups.
- A total of 17 different drugs were prescribed, but regimens varied among patients.
Conclusions:
- Atrial fibrillation and flutter post-CABG were significantly more prevalent in males, particularly those aged 60 to 69 years.
- No other significant predisposing factors were identified in this study population.
Introduction And Objectives:
Atrial fibrillation is a common arrhythmia following coronary artery bypass graft surgery. Its incidence can range from 10 to 60% of patients undergoing coronary artery bypass graft. This rhythm can result in shorter or longer intervals between beats.
Methods:
Medical records of 143 patients from the Queen's Medical Center, Kuakini Medical Center, Saint Francis Medical Center, and Straub Hospital and Clinic, all of which are located in Honolulu, Hawaii were reviewed. An additional 39 records of patients who did not develop these complications were also reviewed as a control group. Patients were selected according to the ICD codes for atrial fibrillation/flutter and coronary artery bypass graft. Both anomalies can lead to increased health care costs, morbidity, and mortality. In this study, possible predisposing factors to these complications were investigated. The time of onset, weight gain, elapsed time, fluid status (in/out), hematocrit, and drug regimens were compared between the two groups.
Results:
The differences in weight gain, fluid status, and hematocrit between the groups were not significant. There were a total of 17 different drugs prescribed to the group as a whole but not every patient received the same regimen.
Conclusions:
Atrial fibrillation and flutter were found to be more common in males, particularly between the ages of 60 and 69 years. There were no other significant findings.
