Hi, I understand your concern and I ll try help you. Survival after coronary artery bypass surgery largely depends on the previous state of the patient and the presence or absence of complications during and after surgery. Patients with cardiac function close to normal before surgery, with a good clinical status and who does not suffer complications during surgery or in the postoperative period, the chance of survival reaches 95%. According to what you reported, the patient is not having a good outcome in the postoperative period of cardiac surgery. And the patient seems to be with some organ dysfunction demonstrated by severe swelling and difficulty opening the eyes. Such problems can tert origin for renal dysfunction, cardiac dysfunction and even neurological dysfunction. To get a better idea of what is happening, it would require larger clinical data. Therefore it is difficult to estimate the chance of survival of this patient, however, it is much lower than the ones who have normal clinical outcome after cardiac bypass surgery, regardless of the number of grafts performed. Hope I have answered your question. If you have any further questions I will be happy to help you. Wish you good health.
