Myocardial infarct patients' hearts undergo substantial remodeling and loss of contractility, and can progress to heart failure. Echocardiographic texture analysis enables us to determine the percentage volume of the infarcted segments in the ventricular volume. The ventricular remodelling is defined in terms of reduced alteration in curvedness index

(%∆C) from end-diastole to end-systole. The cardiac contractility is assessed in terms of the value of the index *dσ\*/dtmax***.** 

With the help of these three indices of percentage volume of MI segments, curvedness index and contractility index, we can track and assess LV progression to heart failure, and its recovery following CABG and SVR.
