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: aricept attending: chief complaint: upper gi bleed major surgical or invasive procedure: none history of present illness: ms. is an 80 year old woman with history of gerd, hypertension, dementia, cad, and esophageal strictures who was admitted with upper gi bleed. she presented to osh for evaluation of nausea/vomiting x 3 days, with coffee ground emesis for the last day. per the records, ng lavage x 2.5l was performed (with no documentation of whether coffee grounds cleared), and she was given esomeprazole and 2l ivf. hematocrit there was 44%. she was guaiac negative at osh. she was transferred to for further evaluation. in the ed, her triage vitals were t97.4f, bp 129/68, hr 62, rr 20, sat 95%2l. she was lavaged another 250cc with 300cc coffee grounds return (no bright red blood). her ngt was placed to suction, and another 500cc of coffee grounds were suctioned out. gi fellow was made aware, and she was transferred to the icu for further management. on the floor, she reports feeling well. she is a&o x 1 (knows year, but not date, does not know place). she denies feeling nauseated, vomiting, or having abdominal pain. review of systems: (+) per hpi (-) denies fever, chills, night sweats, recent weight loss or gain. denies headache, sinus tenderness, rhinorrhea or congestion. denied cough, shortness of breath. denied chest pain or tightness, palpitations. denied nausea, vomiting, (despite hpi) diarrhea, constipation or abdominal pain. no recent change in bowel or bladder habits. no dysuria. denied arthralgias or myalgias. past medical history: -
