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 67-year-old male with a history of high cholesterol who was in his usual state of health until . he was raking leaves on and then developed episodes of mid chest pain and burning which radiated to the left arm. that night he reportedly stopped breathing and was unresponsive. his wife gave him mouth-to-mouth resuscitation and he regained consciousness. he presented to an outside hospital with an acute inferior myocardial infarction and was treated with thrombolytic therapy. his troponin was 20 and he had ekg changes. he underwent catheterization on which revealed a left ventricular ejection fraction of 50%, no mitral regurgitation, insufficiency or hypokinesis. left main coronary artery was narrowed 50-60%, left anterior descending coronary artery 70% proximally, right coronary artery dominant diseased up to 90% proximally in the midportion, 70% distally. the left circumflex coronary artery was 50% proximally, 90% obtuse marginal #3. past medical history: 1. history of high cholesterol. 2. hemorrhoidectomy. 3. carotid disease. medications at home: 1. lipitor 20 mg p.o. q.d. 2. aspirin 325 mg p.o. q.d. 3. lopressor 25 mg p.o. b.i.d. 4. plavix 75 mg p.o. q.d. which has been discontinued prior to surgery. family history: positive for coronary artery disease. social history: no cigarettes. physical examination: in general the patient was in no acute distress, afebrile, vital signs stable. heent: normocephalic, atraumatic. pupils equal, round and reactive to light. extraocular movements intact. nasopharynx benign. neck: supple with full range of motion, no lymphadenopathy nor thyromegaly. carotids were 1+ bilaterally. positive right carotid bruits. lungs: clear to auscultation bilaterally. cardiovascular: regular rate and rhythm, no murmurs. abdomen: positive bowel sounds, soft, nontender, nondistended, no masses, no hepatosplenomegaly. extremities: without cyanosis, clubbing or edema. pulses were 2+ bilaterally throughout. neurologic: nonfocal. hospital course: the patient was admitted to the hospital and on the patient underwent coronary artery bypass grafting x 4 with left internal mammary artery to the left anterior descending coronary artery, saphenous vein graft to the diagonal, saphenous vein graft to obtuse marginal, saphenous vein graft to right coronary artery, posterior descending coronary artery. the patient appeared to have tolerated the procedure and was transferred to the cardiac intensive care unit for postoperative management. he was started on beta blockers. the patient had pacing wires and chest tubes in place, both of which over the course of his stay were removed successfully. the patient did well postoperatively and was transported to the regular cardiac surgery floor where he tolerated a regular diet, ambulated well, did well with his activities of daily living. he was seen by physical therapy and cleared. they requested that he follow up in three to five weeks for endurance training, however then physical therapy followed him a number of times afterward and decided that he was in good condition and did not need further physical therapy. on the patient was in good condition and he is being discharged on a regular heart-healthy diet. he may observe regular activity although he should avoid strenuous activity and should not drive while on pain medications. he should follow up with dr. in four weeks. he should follow up with his cardiologist in two to three weeks and he should follow up with his primary care physician in one to two weeks. discharge medications: 1. lasix 20 mg p.o. q. 12. 2. potassium 20 meq p.o. q. 12. 3. colace 100 mg p.o. b.i.d. 4. aspirin 325 mg p.o. q.d. 5. percocet 1-2 tablets p.o. q. 4 p.r.n. pain. 6. lopressor 12.5 mg p.o. b.i.d. , 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 combined right and left heart cardiac catheterization coronary arteriography using two catheters angiocardiography of left heart structures diagnostic ultrasound of heart diagnoses: coronary atherosclerosis of native coronary artery pure hypercholesterolemia cardiac arrest acute myocardial infarction of other inferior wall, initial episode of care ventricular fibrillation 

Answer: The patient is high likely exposed to
