Design outcomes

Primary

MeasureTime frame
To evaluate the changes in postoperative right ventricular strain using Speckle tracking echocardiography in patients undergoing Off-pump Coronary Artery Bypass Grafting (OPCABG) surgery.Timepoint: Preoperative baseline transthoracic echo (1 day before the surgery) post operative day zero and postoperative day 2 echo readings.—

Secondary

MeasureTime frame
1. To correlate the postoperative right ventricular strain with the conventional echocardiographic parameters. 2. To evaluate the changes in the postoperative right ventricular diastolic function after Off-pump coronary artery bypass grafting surgery. 3. To analyse the changes in right ventricular strain with respect to the placement of coronary artery bypass grafts. 4. To study the changes in right ventricular strain after OPCAB in relation to postoperative outcomes like vasoactive inotropic score, incidence of atrial fibrillation, stroke, renal failure, myocardial infarction, duration of mechanical ventilation, length of ICU stay & length of hospital stay.Timepoint: Preoperative baseline transthoracic echo (1 day before the surgery) post operative day zero & postoperative day 2 echo readings.—
