Short-term outcomes of emergency coronary artery bypass grafting

ObjectivesThis study aims to evaluate short-term outcomes of emergency coronary artery bypass grafting (CABG) surgery, about inotropic support, complications, and early postoperative morbidity and mortality.BackgroundOutcomes of emergency CABG surgery for critical left main coronary artery disease.Patients and methodsForty patients were examined from October 2013 to May 2018. Those included were those who underwent emergency CABG; patients with left main coronary artery disease more than 90% or left main equivalent more than 90%,; and all patients undergoing coronary artery bypass surgery.ResultsMost of our patients had severe chest pain before surgery. Sixteen (40%) patients showed severe chest pain in one or two steps. Fourteen (35%) patients show severe pain during rest, Hemo-dynamic (HD) instability (32.5%), need for inotropes (32.5%), need for intra-aortic balloon pump counterpulsation (67.5%), postoperative bleeding (7.5%), arrhythmia (10%), myocardial infarction (2.5%), renal impairment (2.5%), stroke (2.5%), and in hospital postoperative mortality (2.5%).The study shows a statistically significant difference in the improvement of ejection fraction% in the study group through the whole period of study with a P value of 0.047.ConclusionOur study demonstrated that the patients undergoing emergency CABG have a significant higher preoperative risk especially with myocardial impairment. A reasonable and favorable clinical outcome can be achieved when those patients tolerate the surgery and survive. Also, we assume that establishing hemodynamic stability in conjunction with the cardiologist prior to surgery significantly influences the surgical outcome.
