Puncak Longitudinal Strain Atrium Kiri sebagai Prediktor Kejadian Fibrilasi Atrium pada Pasien yang Menjalani Bedah Pintas Arteri Koroner Tunggal

Abstract

Objective: To determine the relationship between peak longitudinal strain of the left atrium as a predictor of atrial fibrillation in patients after coronary artery bypass surgery. Methode: This was an observational analytical study with a prospective cohort design. The number of samples used in this study was 58 people. Samples were selected using consecutive sampling that met the inclusion and exclusion criteria. Patients will undergo strain analysis before CABG and will be followed for the next 30 days. Resukts: A total of 58 patients were enrolled in this study. The majority of the subjects were male (91,4%) with an average age of 58,6 years. Of the total samples followed, it was found that 19 subjects (32,8%) experienced POAF. The median onset of POAF is 3 days. It was found that PALS < 28% and the use of a heart-lung machine perioperatively had a significant effect on the incidence of POAF (HR: 4,8 (95% CI: 1,36 – 16,9 and HR 4 (95% CI: 1,24 – 13,1, respectively). It was found that the hazard ratio value became higher if these two variables were combined, patients who had both risks were 7,3 times more likely to develop POAF (95% CI: 3,1 – 17,1, p < 0,001). Conclusion: Patients who will undergo CABG with a PALS value < 28% will have a higher risk of POAF than those with a PALS value ≥ 28%. PALS and on-pump CABG are independent predictors for the occurrence of POAF. Patients scheduled for CABG with low PALS values and planned for on-pump CABG can be considered for prophylactic POAF therapy.
