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: asymptomatic major surgical or invasive procedure: replacement of ascending aorta utilzing a 26mm gelweave graft history of present illness: mr. is a 65 year old gentleman with known ascending aortic aneurysm. first diagnosed approximately 4 years ago when echocardiogram was obtained for dizziness. serial ct scans since that time have shown recent increase in size. serial echocardiograms have also shown slight increase in aortic insufficiency. in preparation for cardiac surgical intervention, he underwent cardiac catheterization in which showed essentially normal coronary arteries. his most recent ct scan showed aortic anuerysm measuring 5.4 x 5.2 centimeters. echo from showed 2+ ai, 1+mr and an lvef of 60%. past medical history: ascending aortic aneurysm aortic insufficiency hypertension elevated cholesterol osteaoarthritis insomnia history of bells palsy s/p appendectomy social history: retired mechanic. admits to 40 pack year history of tobacco, quit 20 years ago. admits to occasional etoh intake. he is married with children. family history: denies premature coronary artery disease. physical exam: preop exam vitals: bp 172/108, hr 72, rr 12 general: well developed male in no acute distress heent: oropharynx benign, teeth in fair repair neck: supple, no jvd, heart: regular rate, normal s1s2, no murmur or rub lungs: clear bilaterally abdomen: soft, nontender, normoactive bowel sounds ext: warm, trace edema, no varicosities pulses: 2+ distally neuro: nonfocal pertinent results: 03:55am blood wbc-11.2* rbc-4.01* hgb-12.7* hct-37.2* mcv-93 mch-31.6 mchc-34.2 rdw-13.1 plt ct-97* 03:55am blood glucose-115* urean-18 creat-1.0 na-140 k-3.9 cl-105 hco3-29 angap-10 chest x-ray: small bilateral pleural effusions and bibasilar atelectasis. intraoperative tee: 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. right ventricular chamber size and free wall motion are normal. 4. the aortic root is moderately dilated athe sinus level. the ascending aorta is markedly dilated there are simple atheroma in the aortic arch. the descending thoracic aorta is mildly dilated. there are simple atheroma in the descending thoracic aorta. 5. there are three aortic valve leaflets. there is no aortic valve stenosis. solid mild aortic regurgitation is seen. trivial mitral regurgitation is seen. post-bypass: for the post-bypass study, the patient was receiving vasoactive infusions including phenylephrine. 1. an ascending aorta graft is well positioned. 2. ai is unchanged, the aortic root measure around 3.8 cm now. 3. biventricular systolic function is preserved. 4. other findigns are unchanged brief hospital course: mr. was admitted and underwent replacement of his ascending aorta by dr. . 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 intially required intravenous nitroglycerin for hypertension. oral antihypertensives were resumed and he transferred to the sdu on postoperative day one. he remained in a normal sinus rhythm. beta blockade was slowly advanced as tolerated. over several days, he continued to make clinical improvement with diuresis and was eventually cleared for discharge to home on postoperative day four. at discharge, his incisional pain was well controlled with dilaudid. medications on admission: atenolol 75 qd lipitor 40 qd amoxicillin prn dental work discharge medications: 1. atorvastatin 40 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 2. 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* 3. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 4. potassium chloride 10 meq capsule, sustained release sig: two (2) capsule, sustained release po q12h (every 12 hours) for 7 days. disp:*28 capsule, sustained release(s)* refills:*0* 5. furosemide 20 mg tablet sig: one (1) tablet po bid (2 times a day) for 7 days. disp:*14 tablet(s)* refills:*0* 6. metoprolol tartrate 50 mg tablet sig: 1.5 tablets po bid (2 times a day). disp:*90 tablet(s)* refills:*2* 7. hydromorphone 2 mg tablet sig: 1-2 tablets po every 4-6 hours as needed. disp:*50 tablet(s)* refills:*0* discharge disposition: home with service facility: vna of southeastern mass. discharge diagnosis: ascending aortic aneurysm -
