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: this is a 76-year-old white male with type 2 diabetes, osteoarthritis, who developed bilateral calf claudication. he had an outpatient arteriogram on , at . the patient complained of progressive bilateral calf claudication after 100 ft for the previous year. he denied rest pain or foot ulcerations. he presented for an elective right lower extremity bypass graft. past medical history: 1. type 2 diabetes. 2. osteoarthritis. 3. peripheral vascular disease. past surgical history: 1. left hip replacement. 2. arthroscopy, left knee. allergies: no known drug allergies. medications on admission: 1. glucophage. 2. glyburide. family history: noncontributory. social history: the patient lives with his wife. they live in a mobile home. he uses a cane to ambulate. he still drives a car. he smokes pipe tobacco. he does not drink alcohol. physical examination: vital signs: pulse 61, respirations 12, supine blood pressure right arm 93/46, oxygen saturation 99% on room air, weight 185 lbs, height 5 ft 8 in. general: the patient was an alert, cooperative white male in no acute distress. heent: normocephalic. tongue midline. neck: no jugular venous distention. carotids palpable. no bruits. chest: lungs clear. heart: regular, rate and rhythm without murmur. abdomen: soft and nontender. bowel sounds positive. no bruits. rectal: exam deferred. extremities: there were arthritic changes in extremities. no ulcers of feet. pulse exam: carotid pulses 1+ bilaterally. radial pulses 2+ bilaterally. femoral pulses 2+ bilaterally. pedal pulses with doppler signals bilaterally. neurological: grossly intact. laboratory data: wbc 7.5, hemoglobin 14.7, hematocrit 42.5, platelet count 193,000; pt 12.4, ptt 26.1, inr 1.0; potassium 4.6, bun 27, creatinine 1.0, glucose 133; urinalysis negative. chest x-ray showed no acute pulmonary disease. electrocardiogram showed normal sinus rhythm at a rate of 63, av conduction delay, old inferior/posterior myocardial infarction. hospital course: the patient was admitted to the hospital on , following a right femoral to peroneal in situ saphenous vein graft. at the end of surgery, the patient had a warm foot with a palpable graft pulse and doppler signals of the right pedal pulses. intraoperatively the patient became bradycardiac and became hypertensive. he was treated with intravenous lopressor. he required a few boluses of neo-synephrine. postoperatively the patient was very hypertensive. he was treated with intravenous nitroglycerin. about ten minutes later, he became severely bradycardiac with a heart rate in the 20s. he received 1 mg iv atropine. he remained alert. cardiology was consulted and recommended continuing telemetry for the patient's postoperative wenckebach rhythm which they felt was primarily secondary to intraoperative drugs, especially beta-blockers. they recommended avoiding beta-blockers and using ace inhibitors, diuretics, nitroglycerin or hydralazine for blood pressure control. they felt that a temporary pacemaker was not indicated at the time. they followed the patient during the course of admission. the patient had another episode of asymptomatic sinus bradycardia in the 30s on . cardiology requested that the patient have of hearts ordered. the patient is to follow-up with dr. , eps, in weeks. physical therapy assessed the patient on . the patient requested a rehabilitation stay near his home in . the patient lives in a mobile home with his wife and feels he is not able to manage at home. at the time of dictation, the patient has a warm right foot with a palpable graft pulse and doppler signals of the right pedal pulses. his incision is clean, dry, and intact, and his right foot is warm. the patient will follow-up with dr. in about two weeks for surgical staple removal. dr. office should be called for an appointment, . discharge medications: 1. glyburide 10 mg p.o. b.i.d. 2. metformin 500 mg p.o. t.i.d. 3. regular insulin sliding scale. 4. heparin 5000 u subcue q.12 hours. 5. percocet 1-2 tabs p.o. q.4-6 hours p.r.n. pain. 6. tylenol 325-650 mg p.o. q.4-6 hours p.r.n. disposition: rehabilitation facility. condition on discharge: satisfactory. primary diagnosis: 1. disabling claudication. 2. right femoral to peroneal in situ saphenous vein graft on . secondary diagnosis: 1. asymptomatic bradycardia; of hearts will be placed on . 2. type 2 diabetes. 3. osteoarthritis. , m.d. dictated by: medquist36 procedure: other (peripheral) vascular shunt or bypass diagnoses: diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled atherosclerosis of native arteries of the extremities with intermittent claudication cardiac complications, not elsewhere classified other specified cardiac dysrhythmias 

Answer: The patient is high likely exposed to
