It relieves anginal symptoms, reduces incidences of further myocardial infarction, improves myocardial function, and prevents sudden death.<\/jats:p>\n                    <jats:p>Left ventricular ejection fraction (LVEF) that is most commonly to use to quantify myocardial contractility is not a good marker post CABG. Long term follow-up studies have found conflicting results.<\/jats:p>\n                    <jats:p>Speckle tracking echocardiography (STE) is a promising way to objectively quantify left ventricular function. Global longitudinal strain (GLS) has been found to be a better predictor after CABG. We attempted to see improvement in myocardial function by assessing changes in GLS, post systolic index (PSI) and peak strain dispersion (PSD) 4 weeks and 3 months after CABG.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>In our prospective observational study, we examined 70 patients undergoing CABG.
