Predictive value of left atrial volume index changes in developing post operative atrial fibrillation in post-CABG patients at St. Luke’s Medical Center 2009-2014
Objectives: This study sought whether changes in left atrial volume index (LAVI) can be a predictor in developing post operative atrial fibrillation (POAF)
Design: Retrospective cohort study
Methods: A total of 297 patients who underwent coronary artery bypass graft
( CABG ) from the year 2009-2014. Patients excluded were those with chronic atrial fibrillation and congenital heart disease.
Results: In our study, 297 patients undergo CABG procedure with 76 out of 297 of then developed POAF . LAVI was also statistically changed from pre op to postop with a p value of < 0.0001 in patients with POAF as compared to without occurrence of POAF Among predictive risk factors for developing POAF , only hypertension ( p value 0.988 ) and PAD ( P value 0.999 ) did not show changes in the LAVI measurement.
Conclusion: LAVI changes has strong and significant correlation in developing POAF. Therefore, LAVI changes and its value pre and post op CABG must be done and this will guide the clinicians risk stratify the patients for developing POAF.
