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: mr. is an 85 year-old man who underwent coronary artery bypass grafting x2 as well as aortic valve replacement on by dr. . his postoperative course was uneventful except for atrial fibrillation for which he was discharged on coumadin. the patient was doing well at home until the day before admission when he developed increasing chest pain and fever. ems was called and he was taken to where he was noted to be febrile to 203 in rapid atrial fibrillation with a ventricular response in the 120s and an increased white blood cell count to 18,000 with an inr of 4.2, otherwise unremarkable. his chest x-ray was reportedly negative and he was transferred to the for further work up and care. past medical history: is significant for coronary artery bypass graft x2 as well an aortic valve replacement and tissue valve, coronary artery disease, aortic stenosis, prostate carcinoma, paroxysmal atrial fibrillation, rectal bleeding, status post cauterization, cholelithiasis, status post abdominal aortic aneurysm repair in , status post bilateral hernia repairs, status post right lung surgery, chronic renal insufficiency with a baseline creatinine of 1.1, chronic obstructive pulmonary disease. medications at home: included aspirin 81 mg daily, colace 100 mg b.i.d., flovent 110 2 puffs b.i.d., percocet 5/325 1 to 2 tablets p.o. q 4 to 6 hours p.r.n., atrovent 2 puffs q.i.d., protonix 40 mg daily, lopressor 25 mg b.i.d., lipitor 20 mg daily, bacitracin ointment to air lesions, celexa 10 mg daily and warfarin which is held from on due to an elevated inr. allergies: patient states no known drug allergies. physical examination: at time of admission temperature 99.9, pulse 94, blood pressure 124/70, respiratory rate 24, o2 saturation 94% on 3 liters by nasal cannula. neurologic grossly intact, moves all extremities without difficulty. pulmonary with scattered rhonchi, diminished breath sounds at the bases. cardiovascular: irregularly irregular with no murmur. abdomen is soft and nontender, nondistended. extremities are warm with no edema. sternum is stable with steri-strips. no erythema or drainage. patient was admitted to ct surgery. he was scheduled for a chest ct as well as a chest x-ray and echocardiogram. he was begun on vancomycin and levofloxacin pending the results of blood and wound cultures. chest ct showed a suspicious for small subcutaneous fluid collection. also a deep infected fluid collection. superficial exploration relieved the small fluid collection. culture was sent. the bone appeared to be intact at that time and it was decided to treat the patient conservatively with frequent dressing changes plus or minus the operating room for debridement if there was no significant improvement. over the next several days the patient's wound showed significant improvement with decreasing amounts of drainage and beginnings of granulation tissue in the wound margins. a picc line was placed on hospital day #4 for anticipated long term vancomycin infusions. however, on hospital day 8 it was noted that the patient's sternal drainage had again increased with the wound appearing less stable and at this time decision was made to bring him to the operating room for surgical incisions and drainage of the wound with plus or minus sternal debridement. the patient did indeed undergo sternal debridement once in the operating room. please the operating room report for full details. he tolerated the operation well and was transferred from the operating room to the cardiothoracic intensive care unit. at the time of transfer the patient's chest was open with packed sternal wound. he was also seen by plastic surgery at that time. over the next several days the patient remained in the cardiothoracic intensive care unit. during that period he was chemically paralyzed and sedated with an open chest wound. he remained hemodynamically stable throughout that period and on the patient was brought to the operating room once again for bilateral pectoralis advancement flaps and sternal wound closure. he tolerated this operation well. please seen the operating room report for full details. following wound closure he was transferred from the operating room to the cardiothoracic intensive care unit without complications. following wound closure the patient's paralytics were discontinued. on postoperative day #1 he was weaned from the ventilator and successfully extubated. he was begun on oral beta blockade and his diet was advanced as tolerated and on postoperative day #3 he was transferred to floor for continuing postoperative care and activity advancement. over the next week the patient had an uneventful hospital course. his activity was increased with the assistance of nursing and physical therapy. the drains in his chest were removed by plastic surgery service and on postoperative day #11 and #8 it was decided that the patient was stable and ready to be transferred to rehabilitation. at the time of this dictation the patient's physical is as follows: temperature 98.3, heart rate 74 in atrial fibrillation, blood pressure 116/60, respiratory rate 20, o2 saturation 95% on room air. weight preoperatively 80 kilos, at discharge is 82.5 kilos. laboratory data: white count 7.3, hematocrit 33.8, platelets 266, sodium 140, potassium 4.0, chloride 101, co2 32, bun 13, creatinine 1.1, glucose 97, pt is 18.2 with an inr of 2.1. physical examination: neurologically alert and oriented times three, moves all extremities, follows commands, nonfocal examination. pulmonary: diminished at the bases with scattered rhonchi, otherwise clear. cardiac: irregularly irregular, s1 and s2 with no murmurs. sternum with running sutures, is open to air, clean and dry. bilateral deltoid incisions open to air, clean and dry with one drain draining serosanguineous fluid. abdomen is soft, nontender, nondistended with normoactive bowel sounds. extremities are warm and well perfused with 1 to 2+ edema. additionally the patient has a picc in the left antecubital space, slight without erythema. patient is to be discharged to rehabilitation. he is to have follow up with dr. in the plastic surgery clinic one week following transfer for assessment of drain. follow up with dr. in four to six weeks and follow up with dr. four weeks after discharge from rehabilitation. condition at time of discharge: good. discharge diagnoses: 1. aortic sclerosis - status post aortic valve replacement. 2. coronary artery disease - status post coronary artery bypass graft times two on . 3. status post sternal debridement on . 4. status post pectoralis flap advancement and sternal wound closure on . 5. prostatic carcinoma. 6. abdominal aortic aneurysm repair in . 7. status post right lung surgery. 8. chronic renal insufficiency with baseline creatinine of 1.1. 9. chronic obstructive pulmonary disease. 10. status post bilateral hernia repairs. 11. status post right lung surgery. discharge medications: include combivent 1 to 2 puffs q 6 hours p.r.n., zinc sulfate 220 mg daily times one month, percocet 5/325 1 to 2 tablets q 4
