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: dyspnea on exertion major surgical or invasive procedure: aortic valve replacement with 27mm ce magna pericardial tissue valve. replacement of ascending aorta and hemiarch with 30 mm gelweave graft. history of present illness: this is a 78 year old male with known aaa who was followed closely by dr. . a routine ct scan in revealed a new finding of dilatation of the ascending aorta. he was subsequently referred for cardiac surgical evaluation. further workup included a cardiac catheterization in which confirmed ascending aortic aneurysm with moderate aortic insufficiency. coronary angiography showed a co-dominant system with only a 60-70% stenosis of the mid right coronary artery. left ventriculogram showed an lvef of 60%. a carotid ultrasound in revealed no significant disease of the internal carotid arteries. he was eventually cleared for cardiac surgical intervention after seeing an outside dentist. currently, his symptoms include exertional dyspnea and chest heaviness. he admits to a decreasing exercise tolerance and has gained about 30 pounds over the last year and a half. he denies orthopnea, pnd, palpitations, syncope, and lightheadedness. he does have chronic lower extremity edema. past medical history: ascending aortic aneurysm, aortic valve insufficiency, coronary artery disease, cerebrovascular disease with history of cva in , hypertension, abdominal aortic aneurysm, renal cyst, chronic le edema with left leg ucler, history of temporal arteritis, hemorrhoids, s/p polypectomy, s/p hernia repair, s/p pilonidal cyst, s/p tonsillectomy social history: 60 pack year history of tobacco, quit 16 years ago. he admits to only rare etoh. he is a retired cook and lives alone. family history: denies premature coronary artery disease. physical exam: vitals: bp 130/80, hr 63, rr 14, sat 96% on room air general: obese male in no acute distress heent: oropharynx benign, eomi, sclera anicteric neck: supple, no jvd, transmitted murmur to carotid noted heart: regular rate, normal s1s2, no murmur or rub lungs: clear bilaterally abdomen: obese, soft, nontender, normoactive bowel sounds ext: warm, 2+ edema - left greater than right, no varicosities, venous stasis changes noted left lower extermity pulses: 1+ distally neuro: alert and oriented, nonfocal pertinent results: 06:35am blood wbc-7.3 rbc-3.43* hgb-11.2* hct-29.9* mcv-87 mch-32.8* mchc-37.6* rdw-16.2* plt ct-213# 06:35am blood glucose-118* urean-19 creat-0.7 na-137 k-5.0 cl-104 hco3-26 angap-12 brief hospital course: mr. was admitted and underwent aortic valve replacement with replacement of his ascending aorta and hemiarch. only 15 minutes of circulatory arrest was required. the operation was otherwise uneventful and he was transferred to the csru on inotropic support. due to a postoperative coagulopathy, he required multiple blood products and returned to the operating room for re-exploration and clot evacuation on postoperative day zero. he was brought back to the csru in stable condition. over the next 24 hours, he awoke neurologically intact and was extubated. he weaned from inotropic support without difficulty and intermittently required iv nitro to maintain sbp less than 120 mmhg. low dose beta blockade was concomitantly resumed. amiodarone therapy was also initiated for episodes of paroxsymal atrial fibrillation. he otherwise maintained stable hemodynamics and transferred to the telemetry floor on postoperative day four. beta blockade was advanced as tolerated as he transitioned to oral amiodarone. he remained mostly in a normal sinus rhythm, with a rate in the 80's. over the next several days, he continued to make clinical improvements with diuresis. he also made steady progress with physical therapy. he was discharged to home in stable condition on pod#7. medications on admission: atenolol 50 qd, aspirin 325 qd, plavix 75 qd(stopped pta) discharge medications: 1. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). 2. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). 3. metoprolol tartrate 25 mg tablet sig: one (1) tablet po bid (2 times a day). 4. amiodarone 200 mg tablet sig: two (2) tablet po bid (2 times a day) for 3 days: after dose complete, take 400 mg po daily for 7 days, then decrease dose to 200 mg po daily. disp:*34 tablet(s)* refills:*0* 5. furosemide 20 mg tablet sig: one (1) tablet po q12h (every 12 hours) for 7 days. disp:*14 tablet(s)* refills:*0* 6. potassium chloride 20 meq tab sust.rel. particle/crystal sig: one (1) tab sust.rel. particle/crystal po q12h (every 12 hours) for 7 days. disp:*14 tab sust.rel. particle/crystal(s)* refills:*0* 7. clopidogrel 75 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 8. oxycodone-acetaminophen 5-325 mg tablet sig: 1-2 tablets po every 4-6 hours as needed for pain. disp:*50 tablet(s)* refills:*0* discharge disposition: home with service facility: discharge diagnosis: ascending aortic aneurysm, aortic valve insufficiency, coronary artery disease, cerebrovascular disease with history of cva in , hypertension, abdominal aortic aneurysm, renal cyst, chronic le edema with left leg ucler, history of temporal arteritis, hemorrhoids, s/p polypectomy, s/p hernia repair, s/p pilonidal cyst, s/p tonsillectomy, postoperative atrial fibrillation, postoperative bleeding 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 -
