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 71 year old white male has a known history of coronary artery disease, status post stenting in the past. he underwent cardiac catheterization at on which revealed in-stent restenosis and he was referred for coronary artery bypass graft. his catheterization revealed ejection fraction of 60% and his left main was clear, left anterior descending had a 90% in-stent stenosis, left circumflex had a 50% mid vessel stenosis at the obtuse marginal 1 and a 60% proximal restenosis, right coronary artery had a diffuse 90% stenosis and an in-stent restenosis. the posterior descending artery filled left to right collaterals and he is now admitted for coronary artery bypass graft. past medical history: significant for history of hypertension, history of hypercholesterolemia, status post percutaneous transluminal coronary angioplasty, history of hernia, history of benign prostatic hypertrophy, history of peptic ulcer disease in the distant past. medications on admission: aspirin 325 mg p.o. q. day; atenolol 25 mg p.o. q. day; ................. 20 mg p.o. q. day. allergies: lipitor. social history: he lives with his wife, he smokes 1/2 packs per day for 35 years and quit in . he drinks two to three drinks per day. family history: his family history is significant for coronary artery disease. review of systems: unremarkable. physical examination: on physical examination he is a well developed,morbi well nourished white male in no apparent distress. vital signs were stable and afebrile. head, eyes, ears, nose and throat examination, normocephalic, atraumatic, extraocular movements intact, oropharynx benign. neck: supple, full range of motion, no thyromegaly or lymphadenopathy. carotids 2+ and equal bilaterally without bruits. lungs were clear to auscultation and percussion. cardiovascular examination: regular rate and rhythm. normal s1 and s2 with no rubs, murmurs or gallops. abdomen was soft, nontender with positive bowel sounds. no masses or hepatosplenomegaly. extremities were without cyanosis, clubbing or edema. pulses were 2+ and equal bilaterally throughout. hospital course: he was admitted on and he underwent a coronary artery bypass graft times three with left internal mammary artery to the left anterior descending, and reverse saphenous vein graft to the obtuse marginal and left posterior descending artery. crossclamp time was 43 minutes, total bypass time was 69 minutes. he was transferred to the cardiac surgery recovery unit on propofol and neo-synephrine. he was extubated on postoperative night and remained stable. on postoperative day #1 he had his chest tube discontinued and was started on lasix and lopressor. on postoperative day #2 he went into atrial fibrillation. he was treated with lopressor, amiodarone and converted to sinus rhythm. on postoperative day #3 he was transferred to the floor and that evening he was agitated and had question of alcohol withdrawal and was treated with ativan. on postoperative day #4 this resolved and he had epicardial line discontinued. on postoperative day #6 he was discharged to home in stable condition. his laboratory data on discharge revealed hematocrit 28.8 and platelets 209. white count 6,800, sodium 138, potassium 4.4, chloride 97, carbon dioxide 32, bun 19, creatinine 0.8 and blood sugar 108. medications on discharge: lopressor 25 mg p.o. b.i.d. amiodarone 200 mg p.o. q. day times one month colace 100 mg p.o. b.i.d. zantac 150 mg p.o. b.i.d. ecotrin 325 mg p.o. q. day lasix 20 mg p.o. q. day times ten days potassium 20 meq p.o. q. day times ten days ativan .5 mg p.o. b.i.d. prn benacar 10 mg p.o. q. day multivitamin one p.o. q. day follow up: he will be seen by dr. in two weeks and by dr. in two weeks and by dr. in six weeks. , 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 diagnoses: coronary atherosclerosis of native coronary artery pure hypercholesterolemia unspecified essential hypertension cardiac complications, not elsewhere classified atrial fibrillation 

Answer: The patient is high likely exposed to
