Coronary bypass applications in patients with low ejection fraction: investigation of preoperative, intraoperative and postoperative data

27072

Objective: Left ventricle dysfunction is an important determinant that effects hospital mortality. At the same time, the surgery of these patients is also highly risky. In this study we aimed to evaluate the clinical outcomes of on-pump or off-pump revascularizations in patients with low ejection fraction. Methods: One hundred and twenty-nine patients who have ≤ 40% ejection fraction (EF) was scanned retrospectively. Various variables were (preoperative, intraoperative, postoperative) were compared. It was evaluated that whether patients gets preoperative, intraoperative, postoperative support or not. Results: Eighty-four (65.1%) male and 45 (34.9%) female patient were detected with main age of 65.37 ± 8.49 years. Mean basal metabolism index was detected as 26.33 ± 4.21. The distrubution of EF of patients were as follows; EF is between %40-36 in 74 (57.4%) patients, EF is between %35-31 in 38 (29.5%) patients, and EF is ≤%30 in 17 (13.2%) patients. Mean NYHA Class was detected as 2.16 ± 1.03. Mean bypass count was determined as 3.46 per patient and left internal mammarian artery was used in 92.2% of the patients. Hospital mortality was detected as 5 (3.9%). The main important reasons were cardiac factors or concomitant multiorgan failure. Postoperatvie arrythmias were the most detected complications. Conclusion: The patients who have low left ventricular pump function are benefits myocardial revascularization, although mortality is higher than normal ventricular function. However, inspite the all risk, these patients can be sucessfully operated with experinced hands.
