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 65 year old male with hypertension, diabetes mellitus, hypercholesterolemia and a past smoker, who had recent onset of chest pain and a positive stress test. he was admitted to the cardiac medicine service on , for catheterization. past medical history: 1. coronary artery disease. 2. diabetes mellitus. 3. renal insufficiency. 4. sleep apnea. 5. hypercholesterolemia. medications on admission: 1. cartia 120 mg p.o. q.d. 2. lipitor 10 mg q.d. 3. univasc 15 mg p.o. q.d. 4. atenolol 25 mg q.d. 5. diovan 160 mg q.d. 6. humulin n 30 units q.a.m. and 30 units q.p.m. 7. humulin r 14 units q.a.m. and 8 units q.p.m. allergies: penicillin. hospital course: the patient was admitted to the cardiac medicine service on , prior to his catheterization for prehydration. he underwent catheterization which revealed three vessel disease. cardiac surgery was consulted and the decision to go to the operating room was made. the patient underwent a coronary artery bypass graft times three on , with left internal mammary artery to left anterior descending, saphenous vein graft to om, saphenous vein graft to posterior descending artery. he had an uneventful operative course and was transferred to the csru. he was extubated on the same day. postoperatively, his creatinine did rise from baseline of 2.5 to 3.3. on postoperative day three, he had an episode of atrial fibrillation for which he was treated with amiodarone which initially reverted to normal sinus rhythm and then reverted back to atrial fibrillation. he was stable for transfer to the floor on postoperative day three and his rhythm had changed from atrial fibrillation to a junctional rhythm at this point. subsequently on the floor, he had a smooth postoperative course. his pacing wires were discontinued on postoperative day four. he was ambulating well and was cleared by physical therapy. his pain was under control with p.o. analgesics. he was ready for discharged on postoperative day six. he was discharged home. medications on discharge: 1. lopressor 25 mg p.o. b.i.d. 2. colace 100 mg b.i.d. 3. aspirin enteric coated 325 mg q.d. 4. humulin n 30 units q.a.m. and 30 units q.p.m. 5. humulin r 14 units q.a.m. and 8 units q.p.m. 6. lipitor 10 mg q.d. 7. amiodarone 400 mg q.d. 8. niferex 150 mg q.d. 9. percocet one to two tablets q4-6hours p.r.n. fop: the patient is to follow-up with dr. , primary care physician, two weeks and with dr. in four weeks. he is being discharged home with vna for wound check. , 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 left heart cardiac catheterization diagnostic ultrasound of heart other esophagoscopy diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome pure hypercholesterolemia unspecified essential hypertension cardiac complications, not elsewhere classified atrial fibrillation surgical operation with anastomosis, bypass, or graft, with natural or artificial tissues used as implant causing abnormal patient reaction, or later complication, without mention of misadventure at time of operation unspecified sleep apnea unspecified disorder of kidney and ureter 

Answer: The patient is high likely exposed to
