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 71-year-old male admitted on with an ulcer on his right lateral malleolus. during that admission the patient underwent graft surveillance which revealed focal stenosis of the proximal end of his bypass graft on the left. the patient was treated with intravenous antibiotics and discharged home with dressing changes and linezolid to treat his wound. the patient is readmitted on for revision of his right femoral-pedal graft. past medical history: 1. coronary artery disease status post silent myocardial infarction in . 2. congestive heart failure. 3. ventricular aneurysm by cardiac catheterization on anticoagulation. 4. diabetes mellitus with neuropathy and retinopathy. 5. hypercholesterolemia. 6. history of etoh and cocaine abuse. 7. peripheral vascular disease. past surgical history: 1. bilateral laser therapy. 2. left superficial femoral artery to dorsalis pedis bypass with reversed saphenous vein on . 3. cataract extraction and bilateral trabeculectomy of the right eye. 4. excision of right prepatellar bursa. 5. bilateral knee arthroscopies. 6. right fifth toe debridement. allergies: penicillin causes rash, sulfa causes shock, cipro causes gi upset. medications on admission: 1. lipitor 20 mg p.o. q. day. 2. cozaar 50 mg p.o. q. day. 3. coumadin 5 mg five days a week and 7.5 mg two days a week. 4. aspirin 81 mg q. day. 5. glyburide 5 mg q. day. 6. lopressor 25 mg b.i.d. 7. digoxin 0.125 mg q.d. 8. metformin 500 mg q.a.m., 1,000 mg q.p.m. 9. insulin sliding scale as needed. 10. linezolid 600 mg b.i.d. 11. erythromycin ophthalmic ointment p.r.n. 12. peri-dos 3 tablets p.r.n. 13. senna 2 tablets once a day. social history: the patient is married, a former tobacco and alcohol user. physical examination: the patient was afebrile, vital signs were normal. heart: regular. lungs: clear. abdomen: soft and nontender. extremities: the ulcer on his right lateral malleolus was clean and was granulating well. he had a dopplerable signal in his left dorsalis pedis. hospital course: the patient was admitted on and taken to the operating room for revision of a proximal graft anastomosis on the left with vein patch angioplasty. the patient tolerated the procedure well. his postoperative course was uneventful. he was started on heparin and coumadin given his ventricular aneurysm. his diet was advanced. he was out of bed. on postoperative day two given the fact that the patient was doing well and there were no problems, and his graft was still palpable, he was discharged home in stable condition on his preadmission medications. discharge instructions: 1. b.i.d. damp-to-dry dressing changes to the right lateral malleolus ulcer with ace wrap from foot to ankle. 2. no driving. 3. linezolid 600 mg twice a day until further notification from dr. . 4. follow up with dr. in the office in two weeks and to call or return for any questions or problems. , m.d. dictated by: medquist36 procedure: other revision of vascular procedure diagnoses: coronary atherosclerosis of native coronary artery pure hypercholesterolemia congestive heart failure, unspecified diabetes with neurological manifestations, type ii or unspecified type, not stated as uncontrolled polyneuropathy in diabetes other complications due to other vascular device, implant, and graft diabetes with ophthalmic manifestations, type ii or unspecified type, not stated as uncontrolled background diabetic retinopathy 

Answer: The patient is high likely exposed to
