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: codeine / prednisone / tetanus attending: chief complaint: # bright red blood per rectum major surgical or invasive procedure: colonoscopy history of present illness: 67f h/o diverticulosis, chronic diarrhea, and imi s/p rca bms , admitted to micu given four episodes of brbpr. patient was in her usual state of health when she noted mild lower abdominal cramping with subsequent bright red blood per rectum x4 mixed with diarrhea at midnight on the day of admission. in addition, patient reported taking sublingual nitroglycerin for mild chest pressure and shortness of breath immediately prior to this episode of brbpr. patient denied any lightheadedness or unsteady gait at that time. . of note, patient had undergone colonoscopy in at hospital, which patient stated was for intussusception. from , pt was admitted to for multiple episodes of brbpr, was diagnosed with lower gi hemorrhage diverculosis, and received prbc transfusion with appropriate increase and stabilization of hct; after this admission, pt also reported resolution of her chronic diarrhea. . pt denied h/o easy bruising, bleeding with dental procedures, family history of bleeding. pt's only past h/o bleeding was in the context of endometriosis. pt also reported using sublingual ng nightly to help her sleep. ed: # vs: t 96.3, hr 75, bp 122/60, rr 18, sao2 100% # medications: pantoprazole 40mg iv, lorazepam 2mg iv # clinical course: ng lavage returned light pink fluid which cleared with 60cc fluid. # studies --ekg: nsr;

pink fluid returned via ng likely secondary to trauma from tube placement. hematocrit 32.1 upon arrival at the ed; this decreased to 26.5 upon arrival at the micu. given diverticulosis confirmed per osh colonoscopy, clinically benign abdomen, lower gi crampiness, and no coagulopathy, current bleed likely diverticular bleed, but avm or internal hemorrhoids also possibility. pt's home regimen of atenolol held to avoid masking reflex tachycardia bleeding; home regimen of ace inhibitors held to avoid exacerbating possible hypotension bleeding. pt placed on telemetry to monitor for tachycardia. pt kept npo and started on mag citrate and fleets po prep for colonoscopy and egd to r/o upper pathology. ivf 75cc ns x 1l. her colonoscopy showed avms in the cecum one of which was cauterized, but then bled and was clipped. her hematocrit afterwards was stable, two days later she had a 5 point hct drop and marroon stools. afterwards she tolerated clear liquid diet and her diet was advanced, her hematocrit stablized and gi decided that a repeat scope was not necessary. . # chest pressure: patient denied lightheadedness at the time of bleeding at home, but did report chest pressure and shortness of breath for which she took sl nitroglycerin with relief;
