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: mild dyspnea major surgical or invasive procedure: three vessel coronary artery bypass grafting utilizing the left internal mammary artery to left anterior descending, with vein grafts to the ramus intermedius and plv. replacement of ascending aorta utilizing a 26mm gelweave dacron graft. history of present illness: mr. is a 78 year old male found to have abnormal ecg on routine exam. subsequent ett in was notable for 1.0-1.5mm st depression in v4-v6 at peak exercise. imaging revealed inferoapical and septal ischemia. cardiac catheterization in showed severe three vessel disease and normal lv function. based upon the above results, he was referred for cardiac surgical intervention. past medical history: coronary artery disease, hypertension, hypercholesterolemia, osteoarthritis, depression social history: 40 pack year history of tobacco, quit approximately 38 years ago. admits to drinking several glasses of wine per day. retired. married with one child. family history: brother and sister with cabg in their 80's. denies premature cad. physical exam: vitals: bp 176/94, hr 81, rr 12 general: elderly male in no acute distress heent: oropharynx benign, sclera red without discharge neck: supple, no jvd, no carotid bruits heart: regular rate, normal s1s2, no murmur or rub, distant heart sounds lungs: clear bilaterally abdomen: soft, nontender, normoactive bowel sounds ext: warm, no edema, no varicosities pulses: 1+ distally neuro: nonfocal pertinent results: intraoperative tee: measurements: left ventricle - inferolateral thickness: *1.2 cm (nl 0.6 - 1.1 cm) left ventricle - ejection fraction: 50% to 55% (nl >=55%) aorta - ascending: *4.5 cm (nl <= 3.4 cm) aorta - arch: 2.6 cm (nl <= 3.0 cm) aorta - descending thoracic: *2.7 cm (nl <= 2.5 cm) interpretation: right atrium/interatrial septum: no asd by 2d or color doppler. left ventricle: mild symmetric lvh. normal regional lv systolic function. low normal lvef. lv wall motion: basal anterior - normal; mid anterior - normal; basal anteroseptal - normal; mid anteroseptal - normal; basal inferoseptal - normal; mid inferoseptal - normal; basal inferior - normal; mid inferior - normal; basal inferolateral - normal; mid inferolateral - normal; basal anterolateral - normal; mid anterolateral - normal; anterior apex - normal; septal apex -normal; inferior apex - normal; lateral apex normal right ventricle: normal rv chamber size and free wall motion. aorta: moderately dilated ascending aorta. simple atheroma in ascending aorta. focal calcifications in ascending aorta. normal aortic arch diameter. simple atheroma in aortic arch. focal calcifications in aortic arch. mildly dilated descending aorta. there are complex (>4mm) atheroma in the descending thoracic aorta. aortic valve: mildly thickened aortic valve leaflets. no as. trace ar. mitral valve: mildly thickened mitral valve leaflets. mild mitral annular calcification. mild (1+) mr. tricuspid valve: normal tricuspid valve leaflets. physiologic tr. pulmonic valve/pulmonary artery: physiologic (normal) pr. brief hospital course: mr. was admitted and underwent coronary artery bypass grafting surgery. given intraoperative findings of an ascending aortic aneurysm, he required replacement of his ascending aorta as well. for surgical details, please see seperate dictated operative note. following the operation, he was brought to the csru for invasive monitoring. within 24 hours, he awoke neurologically intact and was extubated without incident. he maintained stable hemodynamics and weaned from neosynephrine without difficulty. his csru course was uneventful, and he transferred to the sdu on postopertive day two. he initially required a 1:1 sitter for some postoperative delirium/confusion. haldol was intermittently utilized for agitation. bursts of paroxsymal atrial fibrillation were noted which resolved with an increase in beta blockade. beta blockade was advanced as tolerated while k and mg levels were monitored and repleted per protocol. he also required several units of packed red blood cells for a postoperative anemia. over several days, his mental status improved. sternal drainage was also noted but there was no clinical evidence of infection. stop medications on admission: hctz 50 qd, simvastatin 80 qd, atenolol 50 qd, aspirin 325 qd, ativan prn discharge medications: 1. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). 2. ranitidine hcl 150 mg tablet sig: one (1) tablet po bid (2 times a day). 3. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). 4. simvastatin 40 mg tablet sig: two (2) tablet po daily (daily). 5. ferrous gluconate 300 mg tablet sig: one (1) tablet po daily (daily). 6. keflex 500 mg capsule sig: one (1) capsule po four times a day for 7 days. disp:*28 capsule(s)* refills:*0* 7. potassium chloride 20 meq packet sig: one (1) po once a day for 7 days. disp:*7 packets* refills:*0* 8. lasix 20 mg tablet sig: one (1) tablet po twice a day for 7 days. disp:*14 tablet(s)* refills:*0* 9. metoprolol tartrate 50 mg tablet sig: three (3) tablet po tid (3 times a day). disp:*270 tablet(s)* refills:*0* discharge disposition: home with service facility: homecare discharge diagnosis: coronary artery disease and ascending aortic aneursym - s/p coronary artery bypass grafting and replacement of ascending aorta, postoperative atrial fibrillation, postoperative anemia, postoperative altered mental status, hypertension, hypercholesterolemia, osteoarthritis, depression discharge condition: good discharge instructions: patient may shower, no baths. no creams, lotions or ointments to incisions. no driving for at least one month. no lifting more than 10 lbs for at least 10 weeks from the date of surgery. monitor wounds for signs of infection. please call with any concerns or questions. followup instructions: cardiac surgeon, dr. in weeks. local pcp, . in weeks. local cardiologist, dr. in weeks. md procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery (aorto)coronary bypass of two coronary arteries resection of vessel with replacement, thoracic vessels diagnoses: coronary atherosclerosis of native coronary artery pure hypercholesterolemia unspecified essential hypertension acute posthemorrhagic anemia thoracic aneurysm without mention of rupture atrial fibrillation depressive disorder, not elsewhere classified delirium due to conditions classified elsewhere osteoarthrosis, unspecified whether generalized or localized, other specified sites 

Answer: The patient is high likely exposed to
