The evaluation of regional and global myocardial function post Coronary Artery Bypass Graft (CABG) by speckle tracking echocardiography technique.

This study aims to evaluate STE to investigate the alterations in global and regional myocardial function after CABG. General and regional parameters were measured for different parts of the myocardium to evaluate the outcome of surgery, dyspnea at rest, dyspnea on exertion, chest pain on exertion, function class, (2D)-STE was performed before and 8-12 weeks after the surgery for the 54 patients. The mean of general parameters including End-Systolic Volume (ESV) (P>0.945), End-Diastolic Volume (EDV) (P>0.816), Ejection Fraction (EF) (P>0.968), and Global Longitudinal Strain (GLS) (P>0.941) were not statistically significant before and after CABG. In spite of the fact that patients' cardiac function improves clinically after CABG surgery, speckle tracking echocardiography findings did not show a statistically significant difference between before and after the surgery in terms of general and regional parameters.
