Abstract
Background and Objectives: Patients with low ejection fraction (EF) are at high risk for postoperative complication and mortality. Our Aim: outcome & effect of coronary artery bypass graft surgery on left ventricular systolic function.
Materials and Methods: This is a descriptive study. Between January 2017 to August 2019, 51 consecutive patients underwent isolated CABG at the Rajarajeshwari medical college and Hospital. Of these, 51 had echocardiographic assessment of LV function, preoperatively with respect to patient characteristics, risk factors, and preoperative two dimension echocardiography (2D ECHO). Depending on findings of 2D ECHO patients were divided into three groups: in Group 1, we included patients with EF 30%–35%, Group 2 comprised patients with EF of 25%–30%, and Group 3 consisted of patients with EF. Appropriate investigations were done.
Results: Hospital mortality rate in present series was 9.8%. Mean grafts were 3.02 per patient. Fourteen (40%) patient had a postoperative complication. EF improved in 78% of patients. Canadian Cardiovascular Society Angina class improved in 42% of patients.
Conclusion: We have shown that cardiac surgery provides long-term cardiac-death-free survival benefit in patients of all subsets of LV function, including poor and very poor LV function.
Keywords: CABG (Coronary artery bypass surgery), low ejection fraction (EF), stunned myocardium.
