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: gi bleed, transfer from major surgical or invasive procedure: exploratory laparotomy total abdominal colectomy with hand sewn two-layer side to end ileo-rectal anastomosis omental pedicle flap history of present illness: this is a 71 year old man with cad s/p stent in , htn, asthma, h/o lgib in secondary to diverticulosis requiring coil embolization by ir, who presented to an outside hospital on with brbpr. he was in his usual state of health until the afternoon of admission when he developed rectal bleeding, passing brbpr and clots. he also complained of mild dizziness on waking up in the morning several days prior to presentation. he denied any cp, sob, abdominal pain, n/v, diarrhea. . on admission to osh, vs: t 98.6, hr 78, bp 179/81, rr 15, o2 sat 98% on ra. hct was initially 44.5, but then decreased to 37.7 and then 33.1 over the next 24 hours. a tagged red cell scan showed active bleeding near the hepatic flexure, which was embolized by ir on . on he was started on clears because no further bleeding had been noted. that evening he was noted to again have brbpr, multiple episodes. he remained hemodynamically stable. hct decreased 31-7 -> 29 and he was transfused 1u prbc. repeat hct remained 29 with continued brbpr noted and he was transfused another unit prior to transfer here. sbp remained 130s, hr 70s. he had a repeat tagged rbc scan which showed recurrent bleeding at the same spot (hepatic flexure) and a second embolization procedure was recommended. this would not be available at for several days, so he was transferred here. . on arrival, he feels well but anxious. he continues to have brbpr every 1-2 hours. he denies any cp, sob, abd pain, n/v, dysuria. . of note, he had a prior lgib in . this occurred in the setting of starting aspirin and plavix in following mi and stent placement. at that time he had a colonoscopy and a bleeding site was cauterized. two days later he re-bled and had an emblization by ir. his plavix had been stopped after his bleeding episode, and he has been maintained on low-dose aspirin since that time. . past medical history: - cad s/p mi with stent to lad in - htn - hypercholesterolemia - asthma - arthritis - h/o h. pylori in past, h/o duodenal ulcer - bph - s/p hernia repair - s/p b/l tkrs - l shoulder repair - colonic polyps - s/p lgib (diverticular bleed) x2 in fall requiring coil embolization by ir and epinephrine injection via colonoscopy social history: retired chemist, lives at home with his wife. quit smoking 25 years ago. has an alcoholic drink occasionally. family history: father had ca in his 70s. physical exam: vs: 99.2, hr 99, bp 179/84, rr 17, o2 sat 98% on ra gen: anxious

presented to an osh with brbpr. s/p angio and embolization, but transferred due to recurrent bleeding and need for repeat angio. . gi bleed: hct stable. lgib, likely diverticular given past history. s/p angio at osh, but with recurrent bleeding. hemodynamically stable, s/p 2u prbc at osh. tagged rbc scan indeterminate here due to presence of too much background (recent prior nuc med scan). angio showed no active bleeding, therefore, no embolization. pt did not have bloody bms here, but hct trended during the first few days. he was transfused a total of 5u prbc here (+2 at osh) so far. serial hcts were checked, he was placed on iv ppi and was taken to the or for colectomy on . asa was held during this time. . **he went to the or on for a total abdominal colectomy. . left eye irritation: he reported to theanesthesia doctors of irritation. he received drops and ointment and his symptoms improved. . gi: he was npo with an ngt and ivf. the ngt was d/c'd pod 2. he was started back on sips on pod 3. he was noted to have abdominal distention and tympany on exam. he was npo and a kub showed dilated loops of small bowel with multiple air fluid levels, most likely a ileus. we awaited return of bowel function. he continued to have burping and was spiting up bile and was also having loose stool. he had a ngt placed, for a post-op ileus, the evening of pod5 and got 2l of dark bilious fluid out. he was still round, distended and nontender. a picc line was inserted on pod 6 and he was started on tpn. he was started back on a diet on pod 9 and his diet was slowly advanced over the next few days. he was tolerating a regular diet at time of discharge. . post-op hypovolemia: he urine output was low and so he received several fluid boluses over pod . his ngt output was initally high, 2-3 liters/day and he was bolused iv fluid to repleat this ngt fluid loss. on pod 7, his urine output began to pick-up and was wnl. . post-op fever: he spike a temp to 101 on the night of pod 7. cxr, blood and urine cultures were done and showed a +uti, enterococcus sp. he was started on iv ampicillin and then was switched to po augmentin and will complete his antibiotic course at home. . pain: he

to 100. he received additional 10mg iv lopressor and responded well. once on the floor, his lopressor was increased to 15mg q6h. he was then switched to po lopressor once tolerating a diet. h/o cad: s/p stent in . no evidence of active ischemia or chest pain during his stay. held bb, asa and acei d/t bleed. was continued on lipitor and started on a bb perioperatively. he should re-start his asa and plavix (dc'd prior to admit) as soon as possible post-op. asa and plavix were restarted on , pod 2. . medications on admission: meds at home: aspirin 81mg daily toprol xl 100mg daily lisinopril
