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: penicillins attending: chief complaint: hypotension, hematemeisis major surgical or invasive procedure: rij arterial line endoscopy history of present illness: hpi: patient is an 81 y/o str resident with a h/o cad, chf who was brought to after complaining of epigastric pain associated with nausea and vomiting of bright red bloody emesis. in addition, the patient was noted to be hypothermic to 93f, as well as minimally responsive when ems arrived on the scene, cold, clammy, and was witnessed to have vomited approximately a cup of "coffee ground red vomit" per ems. per son; he had taken patient out during the day, returning around 4pm at which time he was tired and took a nap. later on he was more lethargic and fell asleep easily; then vomited watery blood around 7pm. the patient had been seen the week prior in the ed for hyponatremia, where he was placed briefly on a 1l fluid restriction. at that time, he was also given a course of avelox for a presumed pna? per patient's son; 2 weeks ago he had 10 day long admission for pneumonia and uti; previously living at home with son but following this admission patient went to short term rehab due to deconditioning. per the osh, the patient was hypotensive upon initial presentation with sbp's in the 50's and hct of 20. the patient was then intubated in the setting of his hypovolemic shock, requiring levophed for blood pressure support and shortly transferred to for further management of his gib. . past medical history: chf (ef=?) cad s/p cabg and pci (pci 8 years ago) in past dm type ii chronic back pain, on percocet and gets epidural injections copd on 2l o2 at home and social history: social history: smoker x 60 + years of 1.5-2 ppd; on nicotine patch since recent hospitalization. prior to recent hospitalization, drank 2-3 beers per night. widowed, one son in the area (lived with him), other son in . family history: noncontributory physical exam: physical exam on admission: vitals: t: bp: 115/41 p: 96 rr: o2sat: 100% on gen: obese white male, intubated, lightly sedated, moving extremeties heent: perrl, eomi, sclerae anicteric. ngt in place draining dark red blood tinged material. no bright red blood, no coffee grounds. neck: supple cv: regular, nl s1/s2, no murmurs, l tlc in place with no erythema or pus at entry site. lungs: poor air movement bilaterally l worse than r w/ expiratory wheezes. no rhonchi abd: soft, non-distended, hypoactive bowel sounds, + hepatomegaly. rectal: guaiac positive, black tarry stool per ed @ osh, no brbpr here ext: no lower extremity edema skin: blanching, mottled appearing skin over distal extremeties pertinent results: 01:45am wbc-21.2* rbc-3.79* hgb-10.7* hct-33.4* mcv-88 mch-28.2 mchc-32.0 rdw-16.5* 01:45am ck-mb-notdone 01:45am ctropnt-<0.01 01:45am lipase-120* 01:45am alt(sgpt)-21 ast(sgot)-30 ck(cpk)-52 alk phos-62 tot bili-0.9 01:45am plt smr-normal plt count-438 01:45am pt-14.5* ptt-23.3 inr(pt)-1.3* 01:45am glucose-161* urea n-38* creat-1.6* sodium-141 potassium-4.5 chloride-110* total co2-20* anion gap-16 03:00am wbc-21.9* rbc-3.28* hgb-9.6* hct-28.9* mcv-88 mch-29.1 mchc-33.1 rdw-16.7* 03:00am tsh-2.0 03:00am albumin-2.7* calcium-7.6* phosphate-4.9* magnesium-1.6 03:00am ck-mb-notdone ctropnt-<0.01 08:29am hct-27.5* 08:29am ck-mb-notdone ctropnt-<0.01 08:29am ck(cpk)-60 09:48am lactate-2.3* 02:46pm ck-mb-notdone ctropnt-0.01 02:46pm ck(cpk)-60 03:21pm hct-27.5* brief hospital course: 81 yo man w/ h/o cad, recent pna, who was transferred with hypotension and hematemesis. # shock: patient with reported systolic bp's in the 50's at osh upon initial presentation requiring levophed for bp support & transferred to on levophed. hypotension likely related to combination of gib plus sepsis in the setting of fever and leukcytosis. given cardiac history and pat, cardiogenic shock was also an option. however a tte showed hyperdynamic ef with fxnal obstruction, and ce were negative. the pt remained dependent on pressors to maintain bp through the hospital course. mr remained febrile throughout the course of hospitalization and was covered for suspected pna with cipro, vanc, flagyl. a sputum culture prelim was postitive for gram neg rods and yeast. the pt under went ct torso with contrast, which showed no evidence of ulcer perforation, small b/l pleural effusions and compressive atelectasis, heterogenous airspace opacity in rul, could be aspiration. although a pna was suspected because of imaging, fevers, and wbc up to 21, no definite source of infection was identified by culture prior to his death #hematemesis/gib: per osh notes, pt presented with bright red emesis, hct of 20, s/p 3u prbc transfusion, with hct on transfer of 33. kub reportedly unremarkable w/no evidence of free air @ osh. hct on admission to 33. on exam, ng lavage: dark maroon colored gastric secretions. stool guaiac + with dark tarry stools at osh. no bright red blood per rectum. inr slightly elevated but platelet count high/normal. recieved a total of 5 u prbc. an upper endoscopy by gi showed large ulcer, clot removed, not actively bleeding. serial hcts remained stable in 28s. due to the patients shock surgery felt that he was not a good surgical candidate likely requiring a prolonged cause of mechanical ventilation and a fairly high surgical mortality risk. the family felt that mr would not want to go through with a surgical procedure. the team talked at length with family about possibilty of bx ulcer to determine if ca. since it was very possible that the bx would be inconclusive or falsely negative, the family declined to pursue. family believes the prolonged trach and peg necessary with stomach surgury would be against the pts wishes. . #respiratory failure: pt intubated @ osh presumably for airway protection given hypotension and poor mental status. cxr shows interval dev't of r lung opacities which may represent pna. the pt remained vent dependent throughout the hosptial stay despite attempts at weaning. #code status: after lengthy discussion with hte pt's son, (health care proxy) as well as the rest of the family the decision was made to transition mr to cmo on . they strongly felts that the prolonged recovery, poor quality of life, and likely trach and peg associated with any surgery to repair the ulcer would be against his wishes. therefore on the pt was extubated, levophed was withdrawen and all abx were stoped. pt discomfort was aggressively treatment with fentanyl and versed gtts. mr remained tachycardic and hypotensive after withdraw of aggressive measures. at approxamitely 3am the pt became progressively bradycardic and the rr lessened. at 410am the pt entered cardiac arrest. on exam at 420am the pt was without a pulse or respirations, pupils were fixed and dilated, and there was no corneal reflex. the pt was pernounced dead at 420am. cause of death was determined to be circulatory failure leading to cardiac arrest with the antecedent cause of acute gib. medications on admission: lisinopril 5mg po daily asa 325 mg po daily lasix 20 mg po daily lopressor 25mg po daily tetracycline 250 mg po 4x/day duonebs q6 hrs combivent 18mcg q6 hrs percocet 5/325 q4-6 hrs prn nitroglycerin sl prn discharge medications: none discharge disposition: expired discharge diagnosis: death circulatory failure leading to cardiac arrest. these events were percipitated by an acute gastrointestinal bleed. discharge condition: expired discharge instructions: expired md procedure: venous catheterization, not elsewhere classified continuous invasive mechanical ventilation for 96 consecutive hours or more parenteral infusion of concentrated nutritional substances other endoscopy of small intestine arterial catheterization insertion of other (naso-)gastric tube transfusion of packed cells diagnoses: congestive heart failure, unspecified unspecified essential hypertension acute kidney failure, unspecified unspecified septicemia iron deficiency anemia secondary to blood loss (chronic) severe sepsis chronic airway obstruction, not elsewhere classified coronary atherosclerosis of unspecified type of vessel, native or graft pulmonary collapse acute respiratory failure pneumonitis due to inhalation of food or vomitus cardiac arrest septic shock chronic or unspecified gastric ulcer with hemorrhage, without mention of obstruction diabetes mellitus without mention of complication, type ii or unspecified type, uncontrolled other and unspecified coagulation defects other dependence on machines, supplemental oxygen
