Role of the Seasonal Cycle in Atrial Fibrillation Seen after Coronary Artery Bypass Surgery ()
ABSTRACT
Background: We aimed to investigate the effect of seasons on atrial fibrillation
that occurred after coronary bypass surgery operation. Method: 187
patients underwent coronary artery bypass operation in our clinic between July 2018 - July 2019. Isolated coronary artery bypass graft
operation was performed with cardiopulmonary bypass to179 of these patients. Forty three patients that
developed atrial fibrillation after coronary bypass operation, demographic,
laboratory findings and date of atrial fibrillation data investigated retrospectively. Results: Forty three patients developed atrial fibrillation after
coronary artery bypass surgery. Forty one patients operated in winter, 48 in
spring, 47 in summer, 43 in autumn and 13 patients developed atrial
fibrillation in winter, 11 (25.6%) in spring, 8 (20.9%) in summer and 11
(23.3%) in autumn respectively. There is no statistical significance found by Z
test that performed for all seasons for atrial fibrillation. Conclusion: There
are many reasons that could play role on developing atrial fibrillation after coronary artery
bypass surgery. There are many publications that report vitamin D deficiency as
a reason for developing atrial fibrillation after coronary bypass surgery. In
our study, we did not evaluate a relationship between the development of post
operative atrial fibrillation and seasons.
