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 71-year-old gentlemen with a several year history of chest "burning." he experiences this sensation on a daily basis, both at rest and on exertion. he denies lightheadedness or paroxysmal nocturnal dyspnea or orthopnea. he experiences claudication after walking approximately an eighth of a mile. on , an exercise stress test revealed inferolateral st depressions and an ejection fraction of 55%. myoview showed that there were reversible filling defects of both the inferior wall and septum. he presented to for elective cardiac catheterization on . coronary artery disease risk factors: positive hypertension, hyperlipidemia, tobacco use, family history, negative diabetes. past medical history: abdominal aortic aneurysm (4 cm in diameter), mild diverticulosis, small aneurysm in the left common iliac artery, peripheral vascular disease. past surgical history: status post bilateral carotid endarterectomy five years prior to admission. medications on admission: captopril 100 mg po b.i.d., hydrochlorothiazide 25 mg po q.d., atenolol 50 mg po q.d., plavix 75 mg po q.d., norvasc 10 mg po q.d., folic acid 1 mg po q.d., lipitor 10 mg po q.d., isordil 20 mg po b.i.d. social history: the patient is married and he has a long history of tobacco use. physical examination on admission: pulse 50. blood pressure 140/80. neurological intact. no deficits. head, eyes, ears, nose and throat: no carotid bruits, no jugular venous distention. pulmonary: clear to auscultation bilaterally. abdomen soft, nontender, nondistended. extremities: no varicosities, 2+ dorsalis pedis pulses bilaterally. cardiac catheterization data0: left main coronary artery with a mid 50% lesion. left anterior descending artery: 60-70% mid vessel stenosis at take-off of the second diagonal. left circumflex artery: there was a 60% ostial stenosis and total occlusion at the av groove. right coronary artery: total proximal occlusion. brief summary of hospital course: mr. was admitted to for a coronary artery bypass graft surgery after his cardiac catheterization because he had left main coronary artery disease. while awaiting coronary artery bypass graft, his clopidogrel was held. he was continued on his outpatient medications and medically managed. during this period, he received standard preoperative work-up for cardiac surgery. on, mr. went to the operating room where he had a coronary artery bypass graft to four vessels (left internal mammary artery to left anterior descending, saphenous vein graft to om1, saphenous vein graft to om2, saphenous vein graft to right coronary artery). dr. performed the procedure. the patient tolerated the procedure well and was transferred to cardiac surgery recovery unit (csru), intubated, and on a neo-synephrine drip. he was extubated on the evening of his operation. on postoperative day number one he remained in the intensive care unit requiring pressory support. by the end of postoperative day number one, he was weaned off pressors and transferred to the patient care floor. chest tubes were removed and plavix was started on postoperative day number two. the remainder of the hospital course was uneventful and uncomplicated. by postoperative day number four, the patient was ambulating to a level three, but admitted shortness of breath and decreased oxygen saturation on ambulation. both the surgical team and physical therapy team felt that this patient was a candidate for rehabilitation. the patient was discharged on postoperative day number six when a rehabilitation bed was available. condition on discharge: stable. disposition: to rehabilitation. discharge medications: 1. lopressor 12.5 mg po b.i.d. 2. lasix 20 mg po b.i.d. times one week. 3. potassium chloride 20 meq po b.i.d. times one week. 4. colace 100 mg po b.i.d. 5. enteric coated aspirin 325 mg po q.d. 6. clopidogrel 75 mg po q.d. 7. percocet 1-2 tablets po q. 4-6 hours prn pain. discharge diagnosis: coronary artery bypass graft times four (). , 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 coronary arteriography using two catheters angiocardiography of left heart structures injection or infusion of platelet inhibitor left heart cardiac catheterization diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome pure hypercholesterolemia unspecified pleural effusion unspecified essential hypertension personal history of tobacco use aneurysm of iliac artery 

Answer: The patient is high likely exposed to
