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. diabetes mellitus for 20-25 years with neuropathy, retinopathy and nephropathy. past surgical history: status post cholecystectomy, status post hernia repair. allergies: percocet/tachycardia. medications on admission: glucovance 5/500 q.d., neurontin 600 mg q.h.s., insulin nph 72 units in the am and 19 units in the pm, insulin regular 2-12 units in am, 6-12 units in the pm, lipitor 10 mg q.d. history of present illness: the patient is a 68 year old gentleman with diabetes mellitus who for the past couple of months experienced worsening of his exercise tolerance. last year he was able to bike five miles which slowly decreased to 3 and over the past couple of months he can barely do one mile. he has also experienced generalized weakness. he occasionally experienced chest tightness with his exercise that radiated to both of his shoulders. he denied shortness of breath, nausea, vomiting, lightheadedness, palpitations or any other symptoms. physical examination: pleasant, cooperative but in no acute distress. vital signs, temperature 98.0, blood pressure 140/80, pulse 100, saturation 95% on room air. respiratory clear to auscultation bilaterally. neck, no jugulovenous distension, no bruits. cardiovascular, regular rate and rhythm, no murmurs. abdomen obese, nontender, nondistended. extremities, 1+ edema of both ankles. laboratory data: on admission white blood cell count 11, hematocrit 42.4, platelets 2299. sodium 139, potassium 4.7, chloride 100, bicarbonate 26, bun 19, creatinine 1.3. hospital course: the patient was admitted to the medicine service for further workup and evaluation. the patient had cardiac catheterization on which showed left anterior descending, long diffuse 80% lesion extending to the ostium, left circumflex 90% bifurcation lesion in the obtuse marginal, right coronary artery small with moderate disease. cardiac surgery was consulted and the patient was a good candidate for coronary artery bypass graft. the patient was taken to the operating room on where coronary artery bypass graft times three with left internal mammary artery to the left anterior descending, saphenous vein graft to obtuse marginal and bifurcation times two was performed without complication. the chest tube and pacing wires were placed intraoperatively. the patient was transferred to the csc unit in stable condition. on postoperative day #1, the patient is afebrile, vital signs are stable but we were unable to wean the patient off of the ventilator because of agitation and increased respiratory rate when we tried to do that. on postoperative day #2 the patient is p.o. feeding 9.3, he was started on levofloxacin and he was extubated successfully. he started working with physical therapy. his chest tube was removed without complications. on postoperative day #3 the patient is afebrile, the vital signs are stable. on postoperative day #4 the patient is afebrile and vital signs are stable. there were no concerns. on postoperative day #5 there were no acute changes. his heartrate was stable on lopressor. he was transferred to the floor in stable condition. on postoperative day #6 the patient had p.o. of 100.7 which decreased with coughing and incentive spirometry. the patient continued on levofloxacin and ambulated with physical therapy. on postoperative day #7 the patient finished his physical therapy and he was medically stable. he was discharged home in stable condition. condition on discharge: good discharge status: the patient was discharged home with to check on the patient's wound. the patient should follow up with dr. in four weeks for postoperative check. the patient will return next week for wound check. medications on discharge: lopressor 25 mg p.o. b.i.d. benadryl 25 mg p.o. q.h.s. prn enteric coated aspirin 325 mg p.o. q.d. ibuprofen 600 mg p.o. q. 6 hours prn lasix 40 mg p.o. b.i.d. times 14 days potassium chloride 20 meq one tablet p.o. b.i.d. times 14 days levofloxacin 500 mg p.o. q. day times seven days lipitor 10 mg p.o. q.d. neurontin 600 mg p.o. q.h.s. insulin nph 72 units in the am, 9 units in the pm, regular 0 to 12 units in am, 6-12 units in pm discharge diagnosis: 1. diabetes mellitus 2. coronary artery disease status post coronary artery bypass graft , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery coronary arteriography using two catheters (aorto)coronary bypass of two coronary arteries left heart cardiac catheterization diagnostic ultrasound of heart diagnoses: nephritis and nephropathy, not specified as acute or chronic, in diseases classified elsewhere coronary atherosclerosis of native coronary artery intermediate coronary syndrome diabetes with neurological manifestations, type ii or unspecified type, not stated as uncontrolled polyneuropathy in diabetes left heart failure diabetes with renal manifestations, type ii or unspecified type, not stated as uncontrolled diabetes with ophthalmic manifestations, type ii or unspecified type, not stated as uncontrolled background diabetic retinopathy 

Answer: The patient is high likely exposed to
