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 a 63-year-old man with recent onset of exertional chest pain. cardiac catheterization done at hospital on the day of admission showed an 80% left main stenosis, 95% left circumflex occlusion with an ejection fraction of 55%. he was transferred from hospital to for coronary artery bypass graft. past medical history: 1. left rotator cuff repair in 2. intermittent back pain medications recently started prior to admission: 1. atenolol 25 mg qd 2. enteric coated aspirin 325 qd 3. lipitor 10 qd 4. ibuprofen 800 mg tid prn allergies: he has no known drug allergies. lab data on : sodium 145, potassium 4.1, chloride 109, co2 28, bun 18, creatinine 1.1, glucose 97. pt 10.2, ptt 27.2, inr 0.7. white blood cell count 4.8, hematocrit 41.7, platelets 222. imaging: electrocardiogram is normal sinus rhythm with normal intervals. social history: former smoker 40 pack year history, quit two months ago. alcohol use one beer per week. admission physical exam: neurologic: alert and oriented with no apparent deficits. pulmonary: lungs are clear to auscultation bilaterally. neck: supple with no carotid bruits. cor: regular rate and rhythm, no murmur noted. abdomen: slightly firm, nontender, positive bowel sounds. right groin with band-aid in place from his catheterization. extremities: warm and well perfuse with no peripheral edema or varicosities. pulses: femorally 2+, radially 2+, dorsal pedis is 1+ on the right and 2+ on the left and posterior tibial is 2+ bilaterally. hospital course: the patient had been npo since prior to his catheterization. following admission to the , the patient was brought to the operating room where he underwent coronary artery bypass grafting. please the operating room report for full details. in summary, the patient had coronary artery bypass graft x2 with left internal mammary artery to the lad and a saphenous vein graft to the om. the patient tolerated the operation well and was transferred to the operating room to the cardiothoracic intensive care unit. the patient did well on the immediate postoperative period. his anesthesia was reversed. he was weaned from the ventilator and successfully extubated. he did require neo-synephrine postoperatively to maintain adequate blood pressure. throughout postoperative day #1, the patient remained in the cardiothoracic intensive care unit as he continued to require neo-synephrine for blood pressure control. on postoperative day #1, his chest tubes were discontinued and he remained hemodynamically stable. on postoperative day #2, the patient was weaned from his neo-synephrine and he was transferred to the floor for continuing postoperative care and cardiac rehabilitation. prior to his transfer, the patient was noted to have a hematocrit of 21 and it was decided at that time not to transfuse the patient as he had not seen blood products up to that point. over the next several days the patient had an uneventful course. his activity level was gradually increased with the assistance of physical therapy and nursing staff. the patient remained hemodynamically stable, however his hematocrit continued to hover around 20. on postoperative day #5, it was noted that the patient became increasingly dyspneic while walking upstairs. his hematocrit was again checked and it was noted to be 19.7. at that time, he was transfused with 2 units of packed red blood cells. on postoperative day #6, the patient was feeling subjectively and it was decided that he was stable and he was ready to be discharged to home. at the time of discharge, the patient's physical exam is as follows: vital signs: temperature 97.8??????, heart rate 64 sinus rhythm, blood pressure 105/50, respiratory rate 20 and o2 saturation 95% on room air. neurologic: alert and oriented x3, moves all extremities, follows commands, conversant. respiratory: breath sounds clear to auscultation bilaterally. heart sounds regular rate and rhythm, s1, s2 no murmur noted. sternum is stable. incision clean and dry. abdomen: soft, nontender, nondistended, positive bowel sounds. extremities: warm and dry, well perfused. lab: white count 7.6, hematocrit 22.5, platelets 305. sodium 139, potassium 4.2, chloride 103, co2 27, bun 25, creatinine 0.8, glucose 98. discharge diagnoses: 1. coronary artery disease, status post coronary artery bypass grafting x2 2. status post left rotator cuff repair in 3. intermittent back pain discharge medications: 1. lasix 20 mg po bid x7 days 2. potassium chloride 20 milliequivalents po bid x7 days 3. lopressor 50 mg po bid 4. niferex 150 mg po qd 5. amiodarone 400 mg po tid x7 days, then 400 mg po bid x7 days, then 400 mg po qd x14 days 6. ibuprofen 400 mg po q6 prn 7. colace 100 mg po bid 8. aspirin 325 po qd 9. lipitor 10 mg po qd 10. dilaudid 6 mg po q 4 to 6 hours prn the patient is to be discharged to home. he is to have follow up with dr. in six weeks. follow up with his primary care provider, . , in three to four weeks. he also is to be followed in the wound clinic at in two weeks. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery (aorto)coronary bypass of one coronary artery diagnoses: coronary atherosclerosis of native coronary artery 

Answer: The patient is high likely exposed to
