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: naproxen / tylenol attending: chief complaint: melena major surgical or invasive procedure: none history of present illness: 88 y/o woman who was brought to hospital ed by her nh today for melanotic stools this am. there she was found to have large, loose, maroon stool and a sbp in the 80's. she was given ns at 100 per hour with correction of her bp, and she was transfused blood (1 unit prbc). there were no unit beds available there, so she was transfered to for further mgmt. of note, she was also recently admitted to hospital (beginning of this month) for lt. knee pain, where and mr revealed a "trabecular fracture" and medial and lateral meniscal tears. orthopedics there recommended immobilization only with a knee immobilizer. on that admission, she was noted to have "new onset atrial fibrillation". she was not started on warfarin given he history of gib (pt. has no recollection of this). . on arrival to the ed here, she was noted to have a hct of 41, and was hemodynamically stable (sbp 116, hr 76). she was observed to have a large maroon stool. her ngl was negative. gi was consulted, and angio consulted for trbc scan and ? embolization. surgery was also consulted. on arrival to the unit, she is found to have a transportation order for dnr/dni status, but states very clearly that she wants everything done in the event of cardiac arrest and or respiratory failure including shocks, compressions, intubation, mechanical ventilatory support. shortly after arrival in the icu, she had an 11-beat run of vt (nsvt). she was also noted to have frequent ectopy and paired pvc's. she is asymptomatic and hemodynamically stable throughout these ectopic/arrhythmic events. she was given 5 iv lopressor times one, and ecg was repeated (no changes vs. prior), and full lab assay sent. . gi and angio contact. are awaiting results of further lab assay and or evidence of ongoing bleeding. plan is trbc scan first if rebleeds, then possible colonoscopy if this is negative. past medical history: htn as - severe (valve area 0.6 cm squared) cva gib (unclear) afib (new as of recent hospitalization - not on any anticoagulation other than aspirin) lt. distal femoral trabecular fracture and lateral and medial meniscal tears anxiety social history: married, lives in family history: noncontributory physical exam: 98.6 83 101/67 14 99% 2 lpm nc nad, elderly, lying in bed dry mm no jvd or lad , no mrg cta anteriorly bs diminished s/nt/obese lt. le in knee immobilizer no edema pertinent results: 08:33pm hct-36.6 04:38pm glucose-113* urea n-26* creat-0.7 sodium-136 potassium-4.8 chloride-102 total co2-28 anion gap-11 04:38pm alt(sgpt)-83* ast(sgot)-124* ck(cpk)-43 tot bili-2.1* 04:38pm ck-mb-notdone ctropnt-<0.01 04:38pm calcium-8.3* phosphate-2.9 magnesium-1.9 04:38pm plt count-198 04:38pm plt count-198 04:38pm pt-16.7* ptt-33.0 inr(pt)-1.5* 02:19pm hgb-16.6* calchct-50 02:15pm glucose-120* urea n-26* creat-0.6 sodium-133 potassium-4.7 chloride-102 total co2-24 anion gap-12 02:15pm ck(cpk)-43 02:15pm ck-mb-notdone ctropnt-<0.01 02:15pm neuts-77.9* lymphs-10.7* monos-6.4 eos-3.5 basos-1.4 02:15pm neuts-77.9* lymphs-10.7* monos-6.4 eos-3.5 basos-1.4 02:15pm plt count-180 02:15pm pt-15.9* ptt-33.9 inr(pt)-1.4* brief hospital course: briefly, this is an 88f with hx. cva, as, gib, afib, lt. femoral fx. who presented from hospital with melanotic stools. on arrival to our ed, the patient was hypotensive. she was stable after 3 l ns. the patient also had nsvt for 11 beats but remained hemodynamically stable with no recurrence of vt. . gib: since the pt has been in the icu, the patient has not had any more melanotic stools. her hematocrit has been stable, with a hematocrit of 34 prior to transfer. she has been on protonix. tagged red blood cell scan on revealed no evidence of bleed. gi was consulted but did not wish to intervene in the setting of nsvt/afib/as unless emergent. the patient will follow up with her pcp. . nsvt: the patient has had no recurrence of this since her episode in the ed. she has been stable on metoprolol 25 mg tid. prior to discharge the was changed to atenolol. . afib: the pt has been rate controlled with bb. plan has been not to anticoagulate her secondary to her gi bleed. . aortic stenosis: echo on reveals severe aortic stenosis with preserved ef. . htn: the patients blood pressure was controlled with metoprolol which was changed back to atenolol 25 mg qd prior to discharge. bumex was also restarted prior to discharge. . left femoral trabecular fx with medial & lateral meniscus tears: the patient was followed by orthopedics, who suggested physical therapy and weight bearing as tolerated. physical therapy cleared the patient for discharge to rehab. . full code medications on admission: asa bumex 1 mg daily atenolol 25 colace nystatin cream to breast oxycodone prn ativan tid discharge medications: 1. lorazepam 0.5 mg tablet sig: one (1) tablet po q8h (every 8 hours) as needed. 2. pantoprazole 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q12h (every 12 hours). 3. oxycodone 5 mg tablet sig: one (1) tablet po q4-6h (every 4 to 6 hours) as needed. 4. atenolol 25 mg tablet sig: one (1) tablet po daily (daily). discharge disposition: extended care facility: life care center of discharge diagnosis: melena nsvt atrial fibrillation aortic stenosis femoral fracture discharge condition: stable, hematocrit stable followup instructions: please follow up with your primary care doctor in 1 week; orthopedics and gi have not made any recommendations about needing follow up with them. procedure: venous catheterization, not elsewhere classified diagnoses: unspecified essential hypertension atrial fibrillation aortic valve disorders paroxysmal ventricular tachycardia blood in stool other fall knee, leg, ankle, and foot injury 

Answer: The patient is high likely exposed to
