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: warfarin attending: chief complaint: evaluatin of ascending aortic aneurysm major surgical or invasive procedure: central left subclavian line history of present illness: 75 yo female with h/o htn, copd, af, ascending aortic aneurysm repair w/ #32 hemshield graft w/ subsequent dehiscence requiring mvr w/ st. jude valve admitted to on w/ epistaxis and back pain. epistaxis treated w/ balloon tamponade. mri () revealed compression fx t8,t9,and t10, stenosis of t7-8,8-9,, l5-s1. cxr () revealed paraspinal mass t6-t10. chest ct w/o contrast () revealed expanding collection of fluid around aortic arch and ascending aorta suspicious for blood, appears to be confined. pt transferred to for further management of ascending aortic aneurysm. on arrival pt noted ongoing back pain. past medical history: hypercholesterolemia, htn, aortic aneurysm repair , cri, copd on chronic steroids pertinent results: 02:20pm glucose-131* urea n-47* creat-1.9* sodium-135 potassium-5.4* chloride-96 total co2-29 anion gap-15 02:20pm calcium-9.5 phosphate-3.3 magnesium-2.1 02:20pm wbc-17.2* rbc-3.30* hgb-9.7* hct-29.5*# mcv-89# mch-29.3 mchc-32.8# rdw-16.5* 02:20pm plt count-292 02:20pm pt-16.7* ptt-21.8* inr(pt)-1.8 01:52pm type-art po2-43* pco2-56* ph-7.39 total co2-35* base xs-6 intubated-not intuba 01:52pm glucose-128* na+-133* k+-5.8* cl--101 01:52pm hgb-10.3* calchct-31 o2 sat-76 01:52pm freeca-1.31 cta compared to the exam of , there has been interval development of a large saccular aneurysm of the ascending aorta, as discussed above, likely related to a leak of the patient's known aortic graft. brief hospital course: 75 yo f w/ ascending aortic aneurysm made dnr/dni shortly after arrival to . ct findings and prognosis were discussed with pt by thoracic surgery. they felt she had an 80% mortality rate with surgical repair of her ascending aortic aneurysm graft. the pt continued to have severe back pain. after discussing comfort measures only with her family she was started on a morphine drip through a left subclavian line. husband was her health care proxy. 1. ascendig aortic aneurysm. etiology of pt's pain. her bp was initially controlled with nipride and esmolol to a goal sbp of <130. they were then d/c'ed when pt was made cmo. pt was given an iv morphine gtt for pain control and iv ativan for anxiety. pt eventually passed away on . cause of death was most likely related to rupture of her aortic aneurysm. 2. copd. prednisone was d/c'ed once pt was made cmo. neb treatments and o2 were continued for comfort. 3. afib. no treatment. 4. cellutitis. d/c'ed keflex. 5. constipation (seen on ct). bowel regimen of senna, colace, and bisacodyl. medications on admission: amnio 200 qd, dig, ditiazem, synthroid 0.1 qd, lopressor xl 50 qd, celebrex, orednisone, lasix 40 qd discharge medications: none discharge disposition: extended care facility: deceased discharge diagnosis: ascending aortic aneurysm rupture discharge condition: deceased discharge instructions: none followup instructions: none procedure: venous catheterization, not elsewhere classified diagnoses: unspecified essential hypertension long-term (current) use of steroids chronic airway obstruction, not elsewhere classified atrial fibrillation constipation, unspecified heart valve replaced by other means thoracic aneurysm, ruptured other complications due to other vascular device, implant, and graft cellulitis and abscess of unspecified sites 

Answer: The patient is high likely exposed to
