Insights
Routine postoperative amiodarone significantly reduced atrial fibrillation after coronary artery bypass grafting (CABG), lowering care costs by €175 per patient. This prevention strategy offers both clinical and economic benefits.
Area of Science:
- Cardiology
- Pharmacoeconomics
- Clinical Trials
Background:
- Atrial fibrillation is a common complication after coronary artery bypass grafting (CABG).
- Preventive strategies for postoperative atrial fibrillation are crucial for improving patient outcomes and reducing healthcare costs.
Purpose of the Study:
- To estimate the costs and health benefits of routine postoperative amiodarone for preventing atrial fibrillation in CABG patients.
- To evaluate the cost-effectiveness of amiodarone prophylaxis in the context of stable angina surgery.
Main Methods:
- A randomized, controlled, double-blind trial (RASCABG study) was conducted.
- 250 CABG patients received either intravenous/oral amiodarone or placebo for 5 days post-surgery.
- Benefit was measured by the avoidance of atrial fibrillation.
Main Results:
- Amiodarone significantly reduced atrial fibrillation incidence (14 vs. 32 cases, p < 0.01).
- No significant difference in length of hospital stay was observed between groups.
- Mean total cost per patient was €7,639 for amiodarone vs. €7,814 for placebo (p < 0.01).
Conclusions:
- Routine postoperative amiodarone effectively reduces the risk of atrial fibrillation post-CABG.
- Amiodarone therapy resulted in a cost saving of €175 per patient.
- The findings support the routine use of amiodarone for atrial fibrillation prevention in CABG patients.
Background:
The purpose of this study was to estimate the costs and health benefits of routinely administered postoperative amiodarone as prevention of atrial fibrillation for patients undergoing coronary artery bypass grafting (CABG) for stable angina.
Methods:
This cost-effectiveness study was based on a randomized, controlled, double-blind trial (the RASCABG study) using avoidance of atrial fibrillation as the measure of benefit at the Department of Cardiothoracic and Vascular Surgery, Aarhus University Hospital, Skejby, Denmark. Two hundred and fifty eligible consecutively enrolled CABG patients were included to receive either 300 mg amiodarone or placebo (5% aqueous dextrose solution) administered intravenously over 20 minutes followed by 600 mg amiodarone/placebo orally twice a day (8 am and 8 pm) for the first 5 postoperative days.
Results:
In the amiodarone group, there were 14 cases of atrial fibrillation compared with 32 in the control group (p < 0.01) whereas there were no differences in the length of stay. The mean total cost per patient was 7,639 euros in the amiodarone group and 7,814 euros in the placebo group (p < 0.01).
Conclusions:
Routine use of postoperative prophylactic intravenous bolus and subsequent 5 days of oral amiodarone therapy after coronary artery bypass grafting reduces the risk of atrial fibrillation and decreases the total costs of care by 175 euros per patient.
