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: history of present illness: the patient is a 77-year-old male with a history of coronary artery disease, endstage renal disease on hemodialysis who presented with a thrombosed right upper extremity av graft. on the day of admission he was taken to the operating room for revision of his av graft. his hospital course will follow. past medical history: 1. significant for end stage renal disease, on hemodialysis. 2. hypertension. 3. coronary artery disease status post myocardial infarction in . 4. ef of 55%. 5. peptic ulcer disease. 6. peripheral neuropathy. past surgical history: 1. coronary artery bypass graft x 5 in . 2. status post abdominal aortic aneurysm repair in . 3. status post cholecystectomy. 4. status post appendectomy. 5. status post right upper extremity av graft. medications on admission: 1. atenolol 25 mg po once daily. 2. lisinopril 5 mg po once daily. 3. simvastatin 10 mg po once daily 4. protonix 40 mg po once daily 5. allopurinol 200 mg po once daily. 6. renagel 800 mg po t.i.d. 7. cinacalcet 30 mg po once daily 8. neurontin 200 mg po tid 9. oxycodone prn. 10. lidoderm patch. allergies: ampicillin, penicillin and norvasc. physical examination: the patient prior to the surgery had a no thrill palpable in his right upper extremity. the graft otherwise was unremarkable. laboratory data: lab studies upon admission were unremarkable. ekg demonstrated first degree av block, right bundle branch block, and sinus rhythm. hospital course: the patient was taken to the operating room on the day of admission where he underwent a right upper extremity av graft, thrombectomy and revision. this case is fully detailed in dr. operative note and also in this gentleman's chart. of note, the anesthesia record demonstrated the patient was hypotensive for a portion of the case requiring neo-synephrine. the case was difficult due to the stenosis which was found and required revision. postoperatively, the patient was taken to the post anesthesia care unit. significant events included bradycardia which was treated with atropine and intravenous fluids. cardiology service evaluated the patient and felt that this most likely represented a reflex of bradycardia secondary to neo- synephrine use. after his treatment with atropine, his rhythm stabilized but he remained hypotensive and levophed was used for pressor support. he was ruled out for myocardial infarction as ekgs remained unchanged. he was brought to the intensive care unit for closer monitoring and slow wean of the levophed. he is currently postoperative day 2. he is weaned off the levophed and he has been hemodynamically stable. all of his laboratory values are unremarkable at this point and he is stable for discharge to home from the intensive care unit. discharge diagnosis: 1. thrombosed right upper extremity av graft. 2. hypotension. 3. bradycardia. 4. endstage renal disease on hemodialysis. 5. coronary artery disease. 6. peptic ulcer disease. 7. hypertension. medications on discharge: 1. atenolol 25 mg po once daily. 2. lisinopril 5 mg po once daily. 3. simvastatin 10 mg po once daily. 4. protonix 40 mg po once daily. 5. allopurinol 200 mg po once daily. 6. renagel 800 mg po t.i.d. 7. cinacalcet 30 mg po once daily. 8. neurontin 200 mg po t.i.d. 9. oxycodone prn. 10. lidoderm patch. 11. tums. disposition: the patient is scheduled to go home to follow up with dr. in 2 weeks and to follow up with his nephrologist as directed. , m.d. procedure: hemodialysis revision of arteriovenous shunt for renal dialysis diagnoses: other iatrogenic hypotension pure hypercholesterolemia coronary atherosclerosis of unspecified type of vessel, native or graft aortocoronary bypass status hypertensive chronic kidney disease, unspecified, with chronic kidney disease stage v or end stage renal disease other specified cardiac dysrhythmias embolism and thrombosis of other specified artery unspecified procedure as the cause of abnormal reaction of patient, or of later complication, without mention of misadventure at time of procedure other complications due to renal dialysis device, implant, and graft peptic ulcer of unspecified site, unspecified as acute or chronic, without mention of hemorrhage or perforation, without mention of obstruction 

Answer: The patient is high likely exposed to
