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: the patient is a 66 year old male who was referred by dr. for outpatient cardiac catheterization secondary to having some symptoms of progressive chest discomfort. he developed some new onset exertional chest discomfort in , which was progressive and worsening and occurred after only climbing one flight of stairs. on , he underwent an exercise treadmill test where he was found to have a large size severe inferolateral reversible defect for which he was sent for cardiac catheterization. hospital course: he underwent cardiac catheterization on , and was found to have complex very proximal 95 percent stenosis of the left anterior descending coronary artery involving d1 and a 50 percent mid left anterior descending coronary artery lesion. the left circumflex had mild disease and the right coronary artery had 100 percent proximal disease. otherwise, the left main coronary artery was normal. given his significant disease, it was recommended that he be referred to cardiac surgery for evaluation. he was seen on , for this and it was felt that he would benefit from coronary revascularization. on , the patient underwent a coronary artery bypass grafting times three of the left internal mammary artery to left anterior descending coronary artery, saphenous vein graft to diagonal, saphenous vein graft to posterior descending coronary artery. his cardiopulmonary bypass time was 55 minutes and his cross clamp time was 39 minutes. the patient tolerated the procedure well and was taken to the post anesthesia care unit on a propofol drip. he was extubated on postoperative day zero and on postoperative day number one, he continued to do quite well and was started on beta blockade and weaned off any vasopressor medications. physical therapy was initiated for the patient and, by postoperative day number two, he was transferred to the floor in good condition and his chest tubes and pacing wires were removed. otherwise, postoperative days three and four were essentially focused on physical therapy and gentle diuresis with lasix. he was seen by physical therapy and they felt it was safe for him to go home with assistance. it was felt on postoperative day number four, as the patient was afebrile and otherwise hemodynamically stable and saturating 97 percent in room air and otherwise making good urine and good pain control with oral medications, that he could be discharged to home. medications on discharge: 1. lasix 20 mg p.o. once daily for five days. 2. potassium chloride 20 meq p.o. once daily for five days. 3. colace 100 mg p.o. twice a day p.r.n. 4. zantac 150 mg p.o. twice a day for two weeks. 5. aspirin 325 mg p.o. once daily. 6. tylenol p.r.n. 7. percocet one to two tablets every four to six hours as needed for pain. 8. lipitor 10 mg p.o. once daily. 9. lopressor 25 mg p.o. twice a day. follow up: he was told to follow-up with dr. in four weeks and otherwise he should follow-up with dr. and dr. in seven to ten days. laboratory data: prior to discharge, his hematocrit was 29.0, platelet count 236,000. blood urea nitrogen was 17 and creatinine was 0.7. , m.d. 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 transfusion of other serum transfusion of platelets diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome pure hypercholesterolemia late effects of acute poliomyelitis 

Answer: The patient is high likely exposed to
