| Scientific title | Prevention of post-operative atrial fibrillation: pathophysyological characterisation of a pharmacological intervention based on a novel model of non-hypoxic pre-conditioning |
| Study acronym | POAF |
| Study objectives | The trial is designed to test the hypothesis that the previous reinforcement of the antioxidant defense system reduces the occurrence of post-operative atrial fibrillation (AF) in patients subjected to cardiac surgery with extracorporeal circulation. Please note that as of 16/01/2013, the following changes were made to the record: 1. The anticipated start date for this trial was updated from 01/07/2007 to 07/01/2007 2. The anticipated end date for this trial was updated from 01/03/2010 to 31/12/2011 |
| Ethics approval(s) | Local Ethics Committees (University of Chile Clinical Hospital, Faculty of Medicine of the University of Chile and Health Ministry of the Chilean Government) approved on the 5th June 2008 (ref: 100) |
| Health condition(s) or problem(s) studied | Post-operative atrial fibrillation |
| Intervention | Oral administration of: 1. Omega-3 polyunsaturated fatty acids: 1 g every 12 hours, beginning 7 days before surgery, until hospital discharge 2. Vitamin C: 500 mg every 12 hours, beginning 2 days before surgery, until hospital discharge 3. Vitamin E: 400 IU daily, beginning 2 days before surgery, until hospital discharge Total duration of follow-up for all arms: 14 days |
| Intervention type | Other |
| Primary outcome measure(s) |
Ocurrence of post-operative atrial fibrillation. Basal electrocardiogram for patients in sinus rhythm and electrocardiographic monitoring will be performed throughout the hospitalisation period, in order to detect the occurrence of atrial fibrillation. |
| Key secondary outcome measure(s) |
1. Biochemical markers of oxidative stress, performed on blood samples withdrawn: 7 and 2 days before surgery, the day of surgery, 8 hours and 4 days after surgery |
| Completion date | 31/12/2011 |
