Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: past medical history: 1. hypertension. 2. history of atrial fibrillation and flutter. 3. history of right inguinal hernia. 4. history of right radical neck resection for squamous cell carcinoma. 5. right thoracotomy. 6. right knee surgery. medications: 1. coumadin. 2. lovastatin. brief hospital course: mr. is an 80-year-old gentleman who was admitted on to - for elective repair of retroperitoneal abdominal aortic aneurysm for a 6.2 x 6.3 x 9.6 cm aneurysm. he was taken to the operating room on , and had a retroperitoneal approach for his abdominal aortic aneurysm repair with tube graft from the infrarenal side to his aortic bifurcation. postoperatively he was noted to be hypotensive and was started on neo- synephrine. over the course of the evening he had a rising lactate and increasing pressor requirement. there was concern of some ischemic episode and he was taken emergently to the operating room on , for exploratory laparotomy. at this point his large bowel and his colon was noted to be green and necrotic. he had a total abdominal colectomy with ileostomy done emergently. his abdomen was left open with i-band and broca to the bag. he was taken back now to the surgical intensive care unit where he stabilized, still requiring pressors and iv fluids throughout the evening. on , his pressor requirement continued to go up and he had a swan in place which showed elevation of pa numbers. he was maxed out on levophed and neo-synephrine at this point as well as vasopressor 1.2 per hour. at this point because of his increasing pa pressures, there was a concern that he may be having a cardiac dysfunction. his lactate remained elevated at 4, however it did not rise. a second look was done at the bedside serially of his abdominal contents to see if there are any signs of small bowel ischemia, however upon inspection there were no clear signs of small bowel ischemia. he also had a stat echo done to evaluate for cardiac function because of his increasing pressor requirement and hypotension. upon evaluation of his cardiac echo he was noted to have significant left ventricular dysfunction with very poor ejection fraction indicating that he had a myocardial event. at this point we discussed with the family that there is significant change in his overall status in that in addition to having some septic physiology he likely was in a cardiogenic shock as well. he went into rapid atrial fibrillation requiring synchronized cardioversion because of hypotension. he was cardioverted twice and went into asystole. chest compressions were immediately started. he received boluses of epinephrine. he was noted then to be in ventricular tachycardia and again hypotensive. he was cardioverted. he was coded for approximately 30 minutes. a lengthy discussion was carried out with the family as to how they would like to proceed. during this time he had somewhat stabilized, however was still hypotensive requiring maximal pressors and was on epinephrine drip. the family, after a lengthy discussion, felt that he would not want to proceed with any further care and he was made cmo. the patient expired shortly thereafter at 6:20 p.m. dr. was informed of the patient's status this entire time. , procedure: parenteral infusion of concentrated nutritional substances other electric countershock of heart temporary ileostomy cholecystectomy suture of vein resection of vessel with replacement, aorta, abdominal transfusion of packed cells cardiopulmonary resuscitation, not otherwise specified repair of other hernia of anterior abdominal wall transfusion of other serum transfusion of platelets diagnoses: acidosis unspecified essential hypertension unspecified septicemia severe sepsis atherosclerosis of aorta atrial fibrillation accidental puncture or laceration during a procedure, not elsewhere classified hemorrhage complicating a procedure personal history of other malignant neoplasm of skin cardiogenic shock long-term (current) use of anticoagulants abdominal aneurysm without mention of rupture acute myocardial infarction of unspecified site, initial episode of care acute vascular insufficiency of intestine other and unspecified coagulation defects other specified disorders of gallbladder inguinal hernia, without mention of obstruction or gangrene, unilateral or unspecified (not specified as recurrent) other allied disorders of spine other ventral hernia with gangrene 

Answer: The patient is high likely exposed to
