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 45 year old man who describes a new onset of exertional chest discomfort over the past five months. for the most part he has noticed burning in his mid chest when walking on the treadmill at the gym. initially he saw his medical doctor who referred him for an exercise treadmill test where he exercised for a few minutes. electrocardiogram had equivocal electrocardiogram changes. this past friday he developed chest pain/heaviness at rest. since then he has been in almost constant pain but it does not seem to worsen with activity. he did try sublingual nitroglycerin tablets without relief. the day of presentation he had an exercise treadmill test with myoview which was verbally reported as being markedly positive for a large area of lateral ischemia. the patient is 5 foot 11 inches, weight 228 lbs. past medical history includes new left shoulder injury and gastroesophageal reflux disease. past surgical history includes right rotator cuff surgery. allergies: no known drug allergies. medications: aspirin 325 mg p.o. q.d.; prilosec 20 mg p.o. q.d.; dyazide 37.5 mg p.o. q.d. laboratory data: labs on admission revealed a white count of 5.7, hematocrit 43.7 and platelets 246. hospital course: the patient was admitted and underwent cardiac catheterization on which showed severe left circumflex, right coronary artery and branch disease, moderate left main and left anterior descending disease. the patient was taken to the operating room on for a three vessel coronary artery bypass graft with left internal mammary artery to the left anterior descending, saphenous vein graft to the obtuse marginal 1 and saphenous vein graft to posterior descending artery. the patient did well postoperatively and went to the coronary surgical recovery unit. the patient was extubated and on postoperative day #1 the patient's chest tubes were removed. the patient's neosynephrine was weaned as tolerated and the patient was transferred to the floor on postoperative day #1. on postoperative day #2 the patient continued to do well and his wires and foley catheter were removed. the patient had a pca for pain control. on postoperative day #2, the patient was seen by physical therapy who felt that he would be fit for discharge after one more visit. on postoperative day #3 his pca was removed and he was started on p.o. percocet. the patient was ambulating up and down the hallways on postoperative day #3. the patient was discharged to home in good condition on postoperative day #4. discharge diagnosis: 1. status post three vessel coronary artery bypass graft discharge medications: 1. metoprolol 12.5 mg p.o. b.i.d. 2. lasix 20 mg p.o. b.i.d. times seven days 3. 20 meq p.o. b.i.d. times seven days 4. colace 100 mg p.o. b.i.d. 5. aspirin 325 mg p.o. q.d. 6. prilosec 20 mg p.o. q.d. 7. percocet 5/325 one to two tablets p.o. q. 4-6 hours prn discharge status: good. discharge disposition: home , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery coronary arteriography using two catheters (aorto)coronary bypass of two coronary arteries angiocardiography of left heart structures left heart cardiac catheterization monitoring of cardiac output by other technique diagnoses: coronary atherosclerosis of native coronary artery esophageal reflux intermediate coronary syndrome unspecified essential hypertension personal history of tobacco use examination of participant in clinical trial 

Answer: The patient is high likely exposed to
