Background and aim of the study: Outcomes of emergency coronary artery bypass grafting (CABG) for acute coronary syndrome (ACS) due to
left main coronary (LM) disease remain unclear. This study aims to assess the short term Outcome for patients undergoing Urgent CABG, due to LM
disease; as assessed by relief of symptoms and 6 months improvement of EF.
Methods: This study included 60 patients that underwent urgent coronary artery bypass grafting. Patients were divided into three groups
according to the pre operative ejection fraction (EF). The three groups were compared regarding preoperative, operative, and postoperative Echo
measurement of Ejection fraction and relief of symptoms.
Results: 70% of our cases were male with mean age of 52.2 yr (range, ±7.19 years), no clinical significance between preoperative comorbidities
in relation between 3 groups and the postoperative outcome, the risk factors for our patients are Preoperative myocardial infarction (MI),
hemodynamic (HD) instability specially in group C and in turn intraoperative risk is; prolonged Cardiopulmonary bypass time and cross clamp time,
while during the intensive care unit stay; postoperative bleeding, MI, prolonged ventilation time and extended ICU stay. The total mortality rate is
8.3% form our patients. Postoperative echocardiography just before discharge and 6 months later showed significant improvement of EF especially
for patient showing preoperative instability and MI.
Conclusion: The present study demonstrated that patients undergoing Urgent CABG have a significant higher preoperative risk especially with
myocardial impairment, despite the higher mortality rate 12%, a favorable clinical outcome can be expected if patients survive. |
