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 a 65-year-old male who, on routine examination, had an abnormal electrocardiogram. this prompted a stress test which was markedly positive. he underwent a catheterization on the day of admission revealing a 100% occluded right coronary artery and 95% occluded left main with preserved left ventricular ejection fraction. the patient denies any history of general symptoms. he has had a left carotid endarterectomy in the past. he had a duplex last week which revealed a normal left carotid artery and an 80% stenosed right internal carotid artery. he has no history of cerebrovascular accidents or transient ischemic attacks. he does have right calf claudication at greater than one mile which is relieved with rest. he denies any orthopnea, paroxysmal nocturnal dyspnea, or lower extremity edema. the patient was transferred to for coronary artery bypass graft by dr. . past medical history: (past medical history significant for) 1. hyperlipidemia. 2. attention deficit disorder. past surgical history: (past surgical history is significant for) 1. status post left carotid endarterectomy. 2. status post removal of pilonidal cyst. 3. status post tonsillectomy and adenoidectomy. 4. status post basal cell carcinoma excision. medications on admission: his medications on admission included aspirin 325 mg p.o. q.d., ritalin 20 mg p.o. b.i.d., multivitamin p.o. q.d., atenolol 25 mg p.o. q.d., lipitor 10 mg p.o. q.d., sublingual nitroglycerin p.r.n., viagra p.r.n. allergies: he has no known drug allergies. physical examination on presentation: on physical examination, the patient was in no acute distress. temperature was 97.9, heart rate of 68 (sinus), blood pressure was 123/72, and 93% on room air. his heart was regular in rate and rhythm with no murmurs. his respiratory examination showed good breath sounds, clear bilaterally. his had positive bowel sounds, with a soft, nontender, and nondistended abdomen. his extremities showed positive dorsalis pedis and posterior tibialis pulses bilaterally. he had no cyanosis or edema in extremities. his neck was supple. he had a right carotid bruit. pertinent laboratory data on presentation: laboratories on admission included a white blood cell count of 9.1, hematocrit of 42.1, platelets of 187. pt of 13.8, ptt of 51.9, inr of 1.3. sodium of 139, potassium of 4.2, chloride of 103, bicarbonate of 27, blood urea nitrogen of 12, creatinine of 1.1, glucose of 98. radiology/imaging: electrocardiogram was significant for normal sinus rhythm, rate of 60, left shift of the axis. q waves in ii, avl, and v1. no acute ischemia on electrocardiogram. hospital course: on hospital day two, the patient went to the operating room with dr. and underwent a coronary artery bypass graft times four. grafts were left internal mammary artery to left anterior descending artery, saphenous vein graft to first obtuse marginal, saphenous vein graft to second obtuse marginal, and saphenous vein graft to posterior descending artery. the patient tolerated the procedure well and was transferred to the intensive care unit, intubated, on neo-synephrine drip, and a propofol drip. in the intensive care unit, the patient was extubated on postoperative day one without incident. he received pulmonary toilet. he had an episode of hypotension when he was placed on neo-synephrine. he was bolused with intravenous fluids, and his mean arterial pressure was greater than 60. he was awake, alert and oriented times three. he remained stable over the first postoperative night. he was weaned off all drips. respiratory status was stable. the patient's diet was advanced, and he was transferred to the floor for the remainder of his recovery. on the floor, the patient remained hemodynamically stable. his chest tubes were discontinued on postoperative day two without incident. his wires were discontinued on postoperative day three without incident. physical therapy worked with the patient, and he is currently an activity level v. he is tolerating a regular diet. his wounds are clean, dry, and intact. discharge disposition: he is in stable condition and is ready for discharge with follow up with dr. in four weeks. discharge diagnoses: 1. coronary artery disease, status post coronary artery bypass graft times four. 2. hypercholesterolemia. 3. attention deficit disorder. medications on discharge: 1. lasix 20 mg p.o. b.i.d. times seven days. 2. potassium cholesterol 10 meq p.o. b.i.d. times seven days. 3. colace 100 mg p.o. b.i.d. 4. enteric-coated aspirin 325 mg p.o. q.d. 5. ritalin 20 mg p.o. b.i.d. 6. multivitamin 1 tablet p.o. q.d. 7. lopressor 25 mg p.o. b.i.d. 8. lipitor 10 mg p.o. q.d. 9. percocet 5/325 one to two tablets p.o. q.4h. p.r.n. condition at discharge: condition on discharge was stable. discharge followup: the patient was to follow up with dr. in four weeks and with dr. (his primary care physician) in two weeks. discharge status: he was discharged to home with services for wound checks. , m.d. dictated by: medquist36 procedure: (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery diagnoses: coronary atherosclerosis of native coronary artery occlusion and stenosis of carotid artery without mention of cerebral infarction other and unspecified hyperlipidemia other and unspecified angina pectoris attention deficit disorder without mention of hyperactivity 

Answer: The patient is high likely exposed to
