بررسی ارتباط شدت اختلال عملکرد دیاستولیک بطن چپ با بروز فیبریلاسیون دهلیزی بعد از عمل جراحی پیوند عروق کرونر

Background and purpose: Atrial fibrillation (AF) is a major cause of mortality and morbidity in patients after coronary artery bypass graft (CABG). Attempt for knowing indices and factor influence post CABG AF may help in finding patients at risk and prevent more complications. This study aimed to evaluate the association between diastolic dysfunction indices and grading with post CABG AF during hospitalization. Material and Methods: We studied 120 patients including 61 men and 59 women with sinus rhythm between November 2012 to January 2013. Before CABG, they were examined by conventional echocardiography and tissue Doppler study and were monitored after surgery before being discharged. Results: Statistically significant relationship was found between post CABG AF, DM, HTN, smoking, and use of ACEI and ARB before surgery. In Doppler tissue study a significant association was detected between LVEF and E´velocity (P0/05). Conclusion: Based on our findings DM, HTN, smoking, LVEF, E´ velocity, ACEI and ARB usage, were independent factors related to the occurrence of AF after CABGs. Using both echocardiography and clinical data could be helpful for risk stratification of occurrence of post CABG AF.
