Abstract
Objective: Increased left atrial diameter (LAD) is associated with the risk of thromboembolism in non-valvular atrial fibrillation (NVAF) patients. The present study was done to evaluate the correlation between LAD enlargement and stroke in NVAF patients.
Materials and Methods: This was a hospital based prospective observational study conducted among 120 atrial fibrillation patients. The patients were divided into two groups; Cases (n=60), NVAF patients with stroke and Controls (n=60) NVAF patients without stroke.
Results: There was no significant difference in the age, sex, BMI, alcohol intake and smoking among the cases and controls. Majority of the patients were in the age range between 71-80 years. Further, M mode anteroposterior dimension of the left atrium, left Atrial dimension in anteroposterior diameter by parasternal approach was significantly higher in cases as compared to control (p<0.05). Based on the cut-off points, in M-mode, 86% of patients in case showed increased left atrial anteroposterior diameter as compared to control only 20% showed increased LAD (p<0.05).
Conclusion: Thus increased LAD is a significant predictor of thromboembolic events in patients with non valvular atrial fibrillation.
