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: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: chest pain major surgical or invasive procedure: coronary artery bypass grafting x4 left internal mammary artery to left anterior descending coronary; reverse saphenous vein single graft from aorta to the 1st diagonal coronary artery; reverse saphenous vein single graft from aorta to the 1st obtuse marginal coronary artery; as well as reverse saphenous vein single graft from aorta to the distal right coronary artery history of present illness: the patient is a 51-year-old gentleman who presented with unstable angina. cardiac catheterization revealed severe 3- vessel coronary disease with preserved left ventricular function. the patient was therefore referred for coronary artery bypass grafting. past medical history: 1) cad, as above, exercise mibi with fixed inferior defect, associated hypokineses. ef reported at 57%. 2)kidney stones 3)colonic polyps - s/p polypectomy social history: he works as teacher in public school. he does not have any smoking or drinking history. family history: mother- died of scd at age 62 father- died of bladder cancer physical exam: afvss neuro:perrl / , equally, answers simple commands, neg pronator drift, sensation intact to st, 2 plus dtr, neg heent: ncat, neg lesions nares, oral pharnyx, auditory neck: supple / farom, neg lyphandopathy, supra clavicular nodes lungs: cta b/l cardiac: rrr without murmers abdomen: soft, nttp, nd, pos bs, neg cva tenderness ext: rle - palp fem, , pt, dp lle - palp fem, , pt, dp pertinent results: intra-op tee for cabg pre-bypass: 1. the left atrium is mildly dilated. no atrial septal defect is seen by 2d or color doppler. 2. left ventricular wall thicknesses and cavity size are normal. overall left ventricular systolic function is normal (lvef>55%). 3. the right ventricular cavity is mildly dilated. right ventricular systolic function is normal. 4. there are simple atheroma in the aortic arch. there are simple atheroma in the descending thoracic aorta. 5. there are three aortic valve leaflets. there is no aortic valve stenosis. trace aortic regurgitation is seen. 6. the mitral valve leaflets are structurally normal. mild (1+) mitral regurgitation is seen. post-bypass: for the post-bypass study, the patient was receiving vasoactive infusions including phenylephrine. 1. regional and global left ventricular systolic function are normal. right ventricular systolic function is normal. 2. mr 3. aorta is intact post decannulation 04:00am blood wbc-6.7 rbc-2.96* hgb-9.3* hct-25.9* mcv-88 mch-31.4 mchc-35.9* rdw-13.9 plt ct-208 04:05am blood glucose-107* urean-12 creat-0.7 na-140 k-4.0 cl-103 hco3-32 angap-9 02:32am blood calcium-8.1* phos-3.2 mg-1.9 chest x-ray: interval development of a small-to-moderate left pleural effusion. brief hospital course: mr , was admitted on for an elective surgery. pre-operatively, he was consented, prepped, and brought down to the operating room for surgery. he underwent the below procedure: procedure: 1. coronary artery bypass grafting x4 left internal mammary artery to left anterior descending coronary; reverse saphenous vein single graft from aorta to the 1st diagonal coronary artery; reverse saphenous vein single graft from aorta to the 1st obtuse marginal coronary artery; as well as reverse saphenous vein single graft from aorta to the distal right coronary artery. 2. endoscopic left greater saphenous vein harvesting. intra-operatively, he was closely monitored and remained hemodynamically stable. he tolerated the procedure well without any difficulty or complication. post-operatively, transferred to the csru for further stabilization and invasive monitoring. within 24 hours, he awoke neurologically intact and was extubated without any sequele. after extubation he was transfered to the floor in stable condition. on the floor, he remained hemodynamically stable with his pain controlled. he remained in a normal sinus rhyth without atrial or ventricular arrhythmias. he progressed with physical therapy to improve his strength and mobility. he continues to make steady progress without any incidents. he was discharged home with services on postoperative day five. medications on admission: asa 81', lipitor 80', plavix 600' (stopped ), metoprolol 12.5", sl ntg prn discharge medications: 1. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). disp:*30 tablet, delayed release (e.c.)(s)* refills:*2* 2. atorvastatin 80 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 3. metoprolol tartrate 25 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*2* 4. lasix 20 mg tablet sig: one (1) tablet po twice a day for 7 days. disp:*14 tablet(s)* refills:*0* 5. ferrous gluconate 300 mg tablet sig: one (1) tablet po daily (daily) for 1 weeks. disp:*30 tablet(s)* refills:*0* 6. ascorbic acid 500 mg tablet sig: one (1) tablet po bid (2 times a day) for 1 months. 7. potassium chloride 20 meq packet sig: one (1) packet po q12h (every 12 hours) for 7 days. disp:*14 packet(s)* refills:*0* 8. oxycodone-acetaminophen 5-325 mg tablet sig: one (1) tablet po q4h (every 4 hours) as needed for pain for 7 days. disp:*30 tablet(s)* refills:*0* 9. ranitidine hcl 150 mg tablet sig: one (1) tablet po bid (2 times a day) for 1 months. disp:*60 tablet(s)* refills:*0* 10. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 11. ibuprofen 600 mg tablet sig: one (1) tablet po three times a day for 2 weeks: take with food. disp:*42 tablet(s)* refills:*0* discharge disposition: home with service facility: homecare discharge diagnosis: cad ulcer dz w/history of ugi bleed asthma htn dyslipidemia discharge condition: good discharge instructions: 1) monitor wounds for signs of infection. these include redness, drainage or increased pain. in the event that you have drainage from your sternal wound, please contact the at (. 2) report any fever greater then 100.5. 3) report any weight gain of 2 pounds in 24 hours or 5 pounds in 1 week. 4) no lotions, creams or powders to incision until it has healed. you may shower and wash incision. please shower daily. no bathing or swimming for 1 month. use sunscreen on incision if exposed to sun. 5) no lifting greater then 10 pounds for 10 weeks. 6) no driving for 1 month. 7) call with any questions or concerns. followup instructions: call your pcp schedule an appointment for 2 weeks. , m. . provider: phone: date/time: 3:00 provider: , md phone: date/time: 11:00 call dr office and schedule an appointment for 4 weeks.

Answer: The patient is high likely exposed to
