Participant of population: Patients (>18 years old) undergoing cardiac surgery (regardless of the pathology for which the surgery is performed), with pericardial fluid who develop post-operative atrial fibrillation.
Intervention: The impact of pericardial fluid following cardiac surgery on the development of post-operative atrial fibrillation.
Comparator: Patients with no pericardial fluid following cardiac surgery.
Study designs to be included: We will include intervention studies: cohort studies, cross-sectional studies and prospective cohort studies.
Main outcome(s): To evaluate the potential role of pericardial biomarkers in the development of post-operative atrial fibrillation
Languages: English
Publication dates: No restrictions
This study is a spin-off from a scoping review and the studies will be searched in the following electronic databases: PUBMED, EMBASE.
During the screening, eligibility, and data extraction phases, the studies will be evaluated in duplicate by 2 independent reviewers. After checking the reviewers' responses, the disagreements will be resolved by a third reviewer. These studies will be organized in the Mendeley reference manager (https://www.mendeley.com/) and subsequently registered in a spreadsheet for data extraction and organization.
The data extraction will include: (1) the study design, (2) number of patients, (3) age of patients, (4) type of cardiac surgery performed, (5) outcome – occurrence of post-operative atrial fibrillation, (6) follow-up period, (7) results – biomarker in the pericardial fluid associated with the occurrence of post-operative atrial fibrillation
