Ongoing epidemiological studies

PREDIMAR

PREDIMAR is an intervention study on secondary prevention of atrial fibrillation. The aim is to reduce the percentage of relapses that occur after an ablation.

This study will include patients with paroxysmal atrial fibrillation (with at least one episode during the last year) or with persistent atrial fibrillation who are operated on with ablation.

The PREDIMAR project is an intervention study comparing two diet-based strategies. A dietitian with experience in this type of study will be responsible for carrying out these interventions. Patients will be randomly assigned to one of the two groups being compared in this study. The difference between the two groups is the level of intensity and frequency with which the dietitian will contact the patients. Both interventions will have a maximum duration of two years.

PREDIMED

The PREDIMED trial is the largest primary prevention trial showing that an intervention to promote a Mediterranean diet is beneficial against the incidence of several major chronic diseases in subjects at high cardiovascular risk, particularly when improved adherence to the Mediterranean diet includes increased consumption of extra virgin olive oil and mixed tree nuts.

This study was conducted in Spain with 7,447 participants and showed a significant (approximately 30%) reduction in the combined endpoint of heart attack, stroke and cardiovascular death.
