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 78-year-old male with a past medical history remarkable for insulin dependent diabetes mellitus, congestive heart failure, who is presenting to the cardiothoracic surgery service for coronary artery bypass grafting for left anterior descending coronary artery, obtuse marginal, and diagonal grafts. past medical/surgical history: 1. insulin dependent diabetes mellitus. 2. congestive heart failure. 3. neuropathy. 4. recent right great toe amputation. 5. nonhealing ulcerations of toe. 6. status post knee surgery secondary to infection. medications at home: 1. glucophage 850 mg p.o. b.i.d. 2. lasix 80 mg p.o. q.d. 3. lisinopril 10 mg p.o. q.d. 4. plavix 75 mg p.o. q.d. 5. digitek 0.125 mg p.o. q.d. 6. spironolactone 25 mg p.o. q.d. 7. coreg 3.125 p.o. b.i.d. 8. nitroglycerin paste p.r.n. 9. nph insulin 20 units subcutaneous b.i.d. allergies: the patient has had allergy to all opiates in the past. family history: he is a retired carpenter. he quit tobacco approximately 25 years prior. he has one beer per month. review of systems: in general the patient had lost about 10 pounds since , not intentionally, secondary to loss of appetite associated with current cardiac disease. skin: denies rashes/lesions. heent: no evidence of dysphagia. he wears glasses. lungs: no evidence of wheezing, no paroxysmal nocturnal dyspnea, requires a single pillow to sleep. cardiac: no palpitations, no chest pain. gi: decreased appetite, no evidence or history of gi bleeding or ulcers. gu: no benign prostatic hypertrophy, no hematuria, no nocturia. musculoskeletal: history of osteoarthritis and neuropathy. peripheral vascular: positive claudication with 30 yards of walking. neurological: no history of tia/cva. he does note some balance problems secondary to neuropathy. endocrine: positive diabetes mellitus, no history of anemia, no thyroid disease. physical examination: the patient is a thin 78-year-old male appearing older than stated age. heent: cranial nerves ii-xii were intact. sclerae anicteric. mucous membranes moist, no evidence of oral ulcers. neck: no cervical lymphadenopathy and no palpable masses. chest: clear to auscultation bilaterally. sternotomy incision had no evidence of erythema, no evidence of drainage. cardiac: regular rhythm and rate, grade 2/6 systolic ejection murmur. abdomen: positive bowel sounds, flat, soft, no masses, no hepatosplenomegaly, no evidence of guarding, no rebound, no tenderness to palpation. extremities: warm, no evidence of varicose veins, no evidence of edema. the graft site appears to be healing well, no evidence of erythema, no evidence of swelling. laboratory data: on the white blood cell count was 13.1, hematocrit 34.6, platelet count 280. this discharge dictation is to be addended with the following discharge summary. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery (aorto)coronary bypass of two coronary arteries diagnostic ultrasound of heart other esophagoscopy catheter based invasive electrophysiologic testing division of sympathetic nerve or ganglion implantation of cardiac resynchronization pacemaker without mention of defibrillation, total system [crt-p] diagnoses: coronary atherosclerosis of native coronary artery congestive heart failure, unspecified chronic airway obstruction, not elsewhere classified cardiac complications, not elsewhere classified diabetes with neurological manifestations, type ii or unspecified type, not stated as uncontrolled polyneuropathy in diabetes other left bundle branch block atherosclerosis of native arteries of the extremities, unspecified atrioventricular block, unspecified 

Answer: The patient is high likely exposed to
