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: no known allergies / adverse drug reactions attending: chief complaint: bright red blood per rectum major surgical or invasive procedure: colonoscopy history of present illness: ms. is a y/o f with a h/o cad s/p cabgx3 in that was complicated by post-op occlusion of her lima requiring 2 stents and aicd/pacer placed for recurrent vt, h/o prior lower gi bleed on coumadin (during cabg), htn and hl who presented from home with brbpr. last night before she went to bed and felt fine, got up in the night to go to the bathroom and she had a bloody/tarry bowel movement and had some blood on her underwear and in the toilet bowl. she then pressed her life line and was brought in by ambulance to the er, this morning she is complaining of feeling tired and fatigued. she has never had a colonoscopy. . in the ed, initial vs were: 97.8, 97, 101/55, 20, 100% on ra. in the er her exam was notable for a grossly bloody rectal exam. labs showed a white count of 16.6, hct of 33.3, from a baseline of 41, and cr of 2.1 from baseline of 1.6. her ekg was sinus tachycardia at 103bpm, q waves in iii and avf. per the patient and her family she is full code but does not want any heroic measures such as a colonoscopy. she received 300cc's of ivf and plan is to transfuse 2 units prbc's, gi is aware of the patient. vs on transfer: 85, 96/54, 26, 99% on ra. . on arrival to the icu her initial vs were: 96.9, 86, 105/57, 28, 100% on 2lnc. shortly after arrival she had a large bowel movement with dark, red blood and clots, on returning from the commode she became lightheaded and her systolic blood pressure dropped into the 80's. she says that the last time she had a stent placed was after her cabg in , she continues to be followed by dr. for her cardiac issues, she says that she has been told she has a heart murmur and has had one for awhile but she does not know which type. no gerd sx, no n/v/d, constipation. . review of systems: (+) per hpi and for lightheadedness/dizziness (-) denies fever, chills, night sweats, recent weight loss or gain. denies headache, sinus tenderness, rhinorrhea or congestion. denies cough, shortness of breath, or wheezing. denies chest pain, chest pressure, palpitations, or weakness. denies nausea, vomiting, diarrhea, constipation, abdominal pain. denies dysuria, frequency, or urgency. denies arthralgias or myalgias. denies rashes or skin changes. past medical history: cad s/p cabg x 3 and stents x 2 to his lima cri - baseline cr is 1.6 htn hl heart murmur - ?aortic stenosis social history: no smoking, no etoh, married, lives w/husband, very active family history: non-contributory physical exam: physical exam on admission: vitals: t: bp: p: r: 18 o2: general: alert, oriented, no acute distress heent: sclera anicteric, mmm, oropharynx clear neck: supple, jvp not elevated, no lad lungs: clear to auscultation bilaterally, no wheezes, rales, ronchi cv: regular rate and rhythm, normal s1 + s2, no murmurs, rubs, gallops abdomen: soft, non-tender, non-distended, bowel sounds present, no rebound tenderness or guarding, no organomegaly gu: no foley ext: warm, well perfused, 2+ pulses, no clubbing, cyanosis or edema . discharge physical exam: pertinent results: labs on admission: 05:30am wbc-16.6* rbc-3.75* hgb-11.7* hct-33.3* mcv-89 mch-31.0 mchc-35.0 rdw-12.7 pt-12.2 ptt-21.7* inr(pt)-1.0 ctropnt-<0.01 glucose-188* urea n-53* creat-2.1*# sodium-142 potassium-4.5 cl-105 co2-22 calcium-7.7* phosphate-2.9 magnesium-1.9 alt(sgpt)-16 ast(sgot)-19 ld(ldh)-147 alk phos-71 tot bili-0.3 imaging: egd (): normal esophagus. normal stomach. normal duodenum. normal egd to third part of the duodenum colonoscopy (): diverticulosis of the whole colon grade 1 internal hemorrhoids. in the proximal ascending colon/cecum was diffuse erythema, nodularity, ulceration and an area of fullness. this involved a 6 cm region. proximal to this was normal mucosa and then in the distal ascending colon was another 3 cm area of erythema, ulceration. (biopsy) otherwise normal colonoscopy to cecum and distal 8 cm of ileum recommendations: follow up biopsies per the team. this may all be consistent with ischemic colitis, less likely malignancy to explain her gi bleeding. ekg: sinus tachycardia at 103bpm, q waves in iii and avf microbiology: stool cultures pending at the time of discharge, no growth to date discharge labs: 06:55am wbc-13.1* rbc-3.87* hgb-12.0 hct-34.3* mcv-89 plt ct-165 glucose-77 urean-10 creat-1.1 na-141 k-3.8 cl-112* hco3-22 angap-11 brief hospital course: ms. is a y/o f with a significant cardiac history who presents from home with brbpr. #) brbpr: ddx initially included diverticular disease, embolic/ischemic event, hemorrhoids (although large amount makes this less likely), avm's or colon cancer. as her most recent hct was 41, she had lost a substantial amount of blood at presentation given her hct of 33. she received a total of 7 units of prbcs, 1 unit ffp, and 1 unit platelets during her stay. by the third day of her admission, her bleeding was stabilized with no further transfusion requirement and a stable hct at 32. she advanced her diet without evidence of further bleeding. the gastroenterology team was consulted and recommended both egd and colonoscopy. the preparation for colonoscopy was prolonged, as she continued to produce bright red blood and clots for more than 24 hours. these tests were performed on , and revealed that the likely cause of her bleeding was an ulceration in the ascending colon near the cecum, possibly secondary to ischemic colitis. malignancy could not be excluded by this study. biopsies were sent for pathologic study and were consistent with ischemic colitis. stool cultures were also sent and were pending at the time of discharge. on discussion with the patient's outpatient cardiologist, dr , it was determined that she does not require multiple anti-platelet agents, particularly given her risk of further bleeding. he recommended stopping and continuing . he will continue to follow her. #) acute on chronic renal failure:the patient's most recent cr at pcp 1.58, but on initial presentation her cr was 2.1. this rapidly returned to baseline with hydration. the etiology was likely acute on chronic renal failure from hypovolemia. during her stay her renal function and urine output was monitored, and her medications dosed for her renal function. #) leukocytosis: her white count was elevated on admission at 16.6, likely due to a stress response. this dropped rapidly. during her admission she remained afebrile with no localizing signs or symptoms of infection. as noted above, stool cultures were pending at the time of discharge, but her gi symptoms had completely resolved. #) cad s/p cabg and stents x 2 to lima: on admission she had no chest pain, and reported no chest pain or other limiting symptoms with exertion at baseline. her home statin was continued. her and were held on admission. per discussion with her outpatient cardiologist, dr , her was discontinued and her continued (as discussed above). #) hypertension: the patient has a history of hypertension, treated with hctz, lisinopril and diltiazem at home. in the setting of her gi bleed and hypotension these were initialy held during her stay. her lisinopril was re-started on , which she tolerated well. hctz and diltiazem continue to be held at discharge. the patient was instructed to follow-up with her pcp early next week for a blood pressure check and further discussion as to whether to re-start these medications. #) copd: the patient has a history of copd, treated with albuterol prn. she had no hypoxia during her stay. transitional issues: - follow-up pending stool cultures - repeat blood pressure check and determine whether to re-start diltiazem and hctz - continue to hold indefinitely medications on admission: aspirin 81mg daily diltiazem 120mg daily lipitor 20mg daily zetia 10mg daily 75mg daily lisinopril 5mg daily hctz 25mg daily albuterol mdi prn sob discharge medications: per cardiologist, d/c , continue discharge disposition: home discharge diagnosis: ischemic colitis coronary artery disease discharge condition: mental status: clear and coherent. level of consciousness: alert and interactive. activity status: ambulatory - independent. discharge instructions: you were admitted to the hospital with a gastrointestinal bleed requiring blood transfusions. you underwent an endoscopy and colonoscopy that was significant for an area of ischemia in your colon (called ischemic colitis). you were treated supportively with iv fluids and blood transfusions, and over time your bleeding stopped. one of your medications, , was discontinued, and you were started on a cream for your back called sarna. due to your bleeding, your blood pressure was lower in the hospital, and two of your blood pressure medications, hydrochlorothiazide and diltiazem, were held. you should not take these until your blood pressure is re-checked in your primary care doctor's office. they may decide to re-start one or both of them at that time. no other changes were made to your home medications. followup instructions: please follow-up with your primary care doctor within three to five days of discharge to discuss the changes to your medications and to ensure you have not had any more bleeding. procedure: other endoscopy of small intestine closed [endoscopic] biopsy of large intestine diagnoses: acute posthemorrhagic anemia acute kidney failure, unspecified chronic airway obstruction, not elsewhere classified aortocoronary bypass status percutaneous transluminal coronary angioplasty status chronic kidney disease, unspecified other and unspecified hyperlipidemia automatic implantable cardiac defibrillator in situ hypovolemia diverticulosis of colon (without mention of hemorrhage) internal hemorrhoids without mention of complication hypertensive chronic kidney disease, benign, with chronic kidney disease stage i through stage iv, or unspecified unspecified vascular insufficiency of intestine
