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, found to have enlarging aortic aneurysm on routine followup major surgical or invasive procedure: redo sternotomy, replacement of ascending aorta and hemiarch (24 millimeter gelweave) and coronary artery bypass grafting utilizing left internal mammary artery to left anterior descending artery history of present illness: mr. is a 53 year old male who first underwent an avr in for congenital aortic stenosis. in , he underwent an urgent redo avr for prosthetic valve endocarditis. since that time, he has done quite well on medical therapy and remains asymptomatic. routine follow up scans have found dilated aortic root and ascending aortic aneurysm. serial scans have found that the diameter has progressively increased. his most recent mri was from which found the aortic root measured 5.2 centimeters(which increased from 4.2 centimeters). based upon the above results, he was referred for cardiac surgical intervention. further workup included a cardiac catheterization which revealed single vessel coronary artery disease, specifically in his left anterior descending artery. past medical history: dilated aortic root and ascending aortic aneurysm, congential aortic stenosis - s/p avr , history of prosthetic aortic valve endocarditis - s/p redo mechanical avr , hypertension, hypercholesterolemia, history of electrical burn injury - s/p right arm amputation and skin grafting, history of left testicular cancer - s/p removal social history: lives alone. denies tobacco history. admits to etoh drinks per day. he works as an excavating contractor. family history: father had mi at age 45. physical exam: vitals: t 98.0, bp 110/60, hr 70, rr 14, sat 96% on room air general: well developed male in no acute distress heent: oropharynx benign, neck: supple, no jvd, heart: regular rate, normal s1s2, crisp valve sounds lungs: clear bilaterally abdomen: soft, nontender, normoactive bowel sounds ext: cool, no edema, no varicosities pulses: 1+ distally neuro: nonfocal pertinent results: 03:15pm blood wbc-5.2 rbc-5.12 hgb-16.5 hct-46.8 mcv-92 mch-32.3* mchc-35.3* rdw-12.7 plt ct-195 03:15pm blood pt-12.5 ptt-22.4 inr(pt)-1.1 03:15pm blood glucose-104 urean-6 creat-0.8 na-140 k-4.2 cl-103 hco3-28 angap-13 08:27am blood wbc-6.2 rbc-3.63* hgb-11.5* hct-32.7* mcv-90 mch-31.8 mchc-35.3* rdw-12.9 plt ct-304 05:35am blood pt-25.1* ptt-109.2* inr(pt)-2.5* 09:20am blood pt-16.6* ptt-64.2* inr(pt)-1.5* 05:17am blood pt-18.6* ptt-150* inr(pt)-1.8* 08:27am blood pt-15.2* ptt-70.6* inr(pt)-1.4* 02:30am blood pt-14.8* ptt-66.0* inr(pt)-1.3* 05:35am blood urean-14 creat-1.1 k-4.8 08:27am blood glucose-115* urean-18 creat-1.0 na-140 k-4.2 cl-104 hco3-26 angap-14 ospital course: on admission, mr. was started on intravenous heparin for his mechanical aortic valve. he underwent routine preoperative evaluation. workup was unremarkable and he was cleared for surgery. on , dr. performed a redo sternotomy, coronary artery bypass grafting with replacement of his ascending aorta and hemiarch. for surgical details, please see operative note. following the operation, he was brought to the csru for invasive monitoring. on postoperative day one, when weaning from sedation, mr. became acutely agitated and self extubated. he concomitantly experienced language and comprehension difficulties. no focal motor deificts were noted. given concern for stroke, a head ct scan was obtained and the neurology service was consulted. the head ct scan found no evidence of hemorrhage or mass effect. hypodensities in the left basal ganglia and possibly the left occipital lobe were noted but of unknown chronicity. based on the above results and concern for postoperative stroke, intravenous heparin was initiated. over the next 24 hours, his language and comprehension difficulities quickly improved. further evaluation included a bedside swallow examination which found no evidence of aspiration. his csru course was otherwise unremarkable and he transferred to the sdu on postoperative day five. he experienced no further neurological insults. his speech and comprehension difficulties completely resolved. he was tranistioned from heparin to warfarin. warfarin was dosed daily for a goal inr between 2.0 and 3.0. he temporarily required picc line for venous access. as medical therapy was optimized, he continued to make clinical improvements with diuresis and made steady progress with physical therapy. once his inr became therapeutic, he was medically cleared for discharge on postoperative day eight. at discharge, his room air saturations were 96%, his bp was 100/60 and hr of 78. he remained in a normal sinus rhythm and tolerated low dose beta blockade. medications on admission: warfarin, lisinopril 5 qd, crestor 5 qd, amoxicillin prn prophylaxis discharge medications: 1. oxycodone-acetaminophen 5-325 mg tablet sig: 1-2 tablets po every 6-8 hours as needed for pain. disp:*50 tablet(s)* refills:*0* 2. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 3. rosuvastatin 5 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 4. folic acid 1 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 5. lisinopril 5 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 6. thiamine hcl 100 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 7. metoprolol tartrate 25 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*2* 8. multivitamin capsule sig: one (1) cap po daily (daily). disp:*30 cap(s)* refills:*2* 9. aspirin 325 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). disp:*100 tablet, delayed release (e.c.)(s)* refills:*2* 10. warfarin 5 mg tablet sig: two (2) tablet po qpm: take as directed by md. dose may vary according to inr. disp:*120 tablet(s)* refills:*2* discharge disposition: home with service facility: discharge diagnosis: ascending aortic aneurysm, aortic insufficiency, coronary artery disease -
