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 an 81 year old man who is a patient of , who presents for cardiac surgery following worsening symptoms of coronary disease and documented multi-vessel coronary artery disease. he has a known history of coronary artery disease dating back to when he had an inferolateral non-q wave myocardial infarction. he did have a catheterization in because of worsening anginal symptoms. it is unclear whether or not he had any intervention at that time. however, since then, he has been doing well without any significant angina. over the past nine months, he has redeveloped exertional symptoms that he describes as mid-chest and neck pain while walking on a treadmill. this is relieved with a single sublingual nitroglycerin. most recently, his symptoms have started occurring when walking at a slow pace. he has had no rest symptoms. he also denies any claudication, orthopnea, paroxysmal nocturnal dyspnea or lightheadedness. he does have chronic ankle edema. past medical history: 1. coronary artery disease status post non-q wave myocardial infarction. 2. hypertension. 3. hypercholesterolemia. 4. diet controlled diabetes mellitus. 5. cervical spondylosis. 6. spinal stenosis. past surgical history: 1. remote labyrinthectomy due to meniere's disease. 2. hernia repair. allergies: the patient has no known drug allergies. medications: 1. aspirin 325 mg p.o. q. day. 2. lipitor 10 mg p.o. q. day. 3. prilosec 20 mg p.o. q. day. 4. zestril 20 mg p.o. q. day. 5. procardia xl 30 mg p.o. q. day. 6. nitroglycerin patch 0.2 mg per hour during the day. 7. folate. 8. vitamin e 400 international units p.o. q. day. 9. flomax 0.4 mg q. day. 10. multivitamin. 11. omega iii. 12. colanzem q. 13. saw . 14. atenolol which was recently increased from 75 to 100 mg q. day. laboratory: studies on admission were white blood cell count of 7.2, hematocrit 36.0, platelets are 240. bun and creatinine are 16 and 1.1. physical examination: on physical examination, he was a well developed, well nourished man appearing younger than his stated age. his heart rate was 60; his blood pressure was 140/60; he had no jugular venous distention. his lungs are clear. his heart was a regular rate and rhythm without murmur. abdomen was benign. neurologically, he was nonfocal. hospital course: the patient was admitted to the hospital for a cardiac catheterization. this revealed coronary disease in multiple vessels. he was started on intravenous heparin and cardiac surgery was consulted. the following day, he was taken to the operating room where he had coronary artery bypass grafting times three. his grafts are left internal mammary artery to the left anterior descending; saphenous vein graft to right coronary and saphenous vein graft to pda and ramus (?). the patient's procedure itself was unremarkable. the patient was found to be a difficult intubation. postoperatively, the patient was taken intubated to the intensive care unit. he was atrially paced but did not appear to have any drips. he was extubated overnight in the presence of anesthesia and the following day was stable enough to be transferred to the floor. his chest tubes were discontinued prior to his transfer. upon arrival to the floor, he resumed what was initially a normal postoperative course. his foley catheter and pacing wires were removed in a normal fashion. on the evening of his third postoperative day, the patient had an episode of rapid atrial fibrillation that was treated successfully with intravenous lopressor. the following day, his heart rhythm remained in atrial fibrillation although it was much more rate controlled. this converted spontaneously back to a sinus rhythm on an increased dose of oral lopressor. after he was in sinus rhythm for approximately 24 hours, it was deemed safe to discharge the patient home. on the first postoperative day, the patient was eating, ambulating and voiding and was cleared by physical therapy to go home. he was discharged to the care of his family with visiting nurse assistance. discharge instructions: 1. he is to follow-up with dr. , his primary care physician and cardiologist in two weeks. 2. he will follow-up with dr. in approximately four weeks. discharge medications: 1. enteric coated aspirin 325 mg q. day. 2. colace 100 mg twice a day. 3. lasix 20 mg twice a day times seven days. 4. potassium chloride 20 meq twice a day times seven days. 5. lipitor 10 mg p.o. q. day. 6. metoprolol 50 mg twice a day. 7. prilosec 20 mg q. day. 8. flomax 0.4 mg q. day. 9. percocet 5/325, one to two p.o. q. four to six hours p.r.n. 10. tylenol 650 mg q. four to six hours p.r.n. 11. ibuprofen 400 mg q. four to six hours p.r.n. discharge diagnoses: 1. unstable angina. 2. coronary artery disease. 3. coronary artery bypass graft times three. 4. diet controlled diabetes mellitus. 5. hypertension, controlled. 6. hypercholesterolemia. , 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 angiocardiography of left heart structures left heart cardiac catheterization coronary arteriography using a single catheter diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome pure hypercholesterolemia unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled atrial fibrillation old myocardial infarction 

Answer: The patient is high likely exposed to
