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: history of present illness: eighty-five year old woman who on day of admission had an episode of nausea and vomiting. patient vomited clear emesis initially. this was followed by greater than five episodes of coffee-ground emesis. she believes that she vomited a half gallon of fluid. she felt weak, and came to the emergency department. in the emergency department, her vital signs were stable. blood pressure 142/65, pulse of 60, o2 saturation 98% on room air. gastric lavage showed bright red blood that did not clear after 700 cc of lavage. she received urgent gastroenterology consult and urgent upper endoscopy which will be detailed later in this discharge summary. past medical history: 1. abdominal aortic aneurysm 6 cm. 2. patient is status post pacemaker placement in at for tachycardia/bradycardia syndrome. 3. patient has had multiple skin cancers resected. medications at home: 1. aspirin 81 mg q day. 2. metoprolol 25 mg . 3. patient is noncompliant with digoxin 0.125 mg q day. allergies: no known drug allergies. social history: patient smoked cigarettes per day for 50 years, quit this year. she does not drink. she lives alone. physical examination on admission: temperature 97.8, pulse 60, blood pressure 142/80, respiratory rate 18, and o2 saturation 98% on room air. in general, a thin elderly woman in no apparent distress. heent: oropharynx is dry. chest was clear to auscultation bilaterally. cardiovascular: regular, rate, and rhythm, no murmurs, rubs, or gallops. abdomen is soft and nontender with a large central pulsatile mass. extremities with trace edema. rectal examination is heme positive. laboratory studies on admission: white blood cells 12.1, hematocrit 34.1, platelets 189. pt/ptt 12.6/25.3, inr 1.0. sodium 140, potassium 4.7, chloride 108, co2 19, bun 76, creatinine 1.2, platelets 123. patient's hematocrit had fallen to 25.0 12 hours after admission. she was transfused 5 units of red blood cells and hematocrit remained stable from 33 to 35 over the next four days. imaging studies: a chest x-ray was performed which was normal, and showed the presence of a pacemaker. a ct scan of the abdomen was performed showing a 6 x 5.4 cm infrarenal aneurysm in the anterior abdominal wall as well as a 4.3 x 4.0 cm aneurysm in the right common ileac artery. the ct scan also showed diverticulosis. laboratory studies is also significant for a serum positive for h. pylori antibody. impression and plan: a generally healthy 85-year-old woman presenting with acute onset of apparent upper gastrointestinal bleeding. in terms of her issues: 1. gastrointestinal bleeding: patient had two large bore ivs placed, and was transfused 5 units of packed red blood cells on the first 24 hours of admission. hematocrit subsequently remained stable. two upper endoscopies were done which showed multiple ulcers in the antrum as well as the lesser curvature of the stomach. they were injected with epinephrine. patient also had serum h. pylori antibodies sent which was positive, therefore she was started on antibiotic therapy with amoxicillin and clarithromycin. she was also started on protonix on arrival to the hospital. 2. h. pylori infection: patient is to complete a two week course of amoxicillin 1,000 mg and clarithromycin 500 mg . she should receive protonix indefinitely. she is also advised that she may not take aspirin again. 3. abdominal aortic aneurysm: patient's abdominal aortic aneurysm is stable compared to her known baseline. patient wishes conservative management at this time, and will not pursue surgery at this time. 4. hypertension: patient was hypertensive her last few days on the hospital floor in light of her hypertension as well as her abdominal aneurysm, her metoprolol dose was increased from 25 mg to 50 mg for better hypertension control. medications on discharge: 1. amoxicillin 1,000 mg . 2. clarithromycin 500 mg (to complete a two week course). 3. protonix 40 mg q day. 4. digoxin 0.125 mg q day. 5. metoprolol 50 mg . discharge diagnoses: 1. upper gastrointestinal bleeding. 2. anemia requiring transfusion. 3. gastric ulcer disease. 4. hypertension. 5. abdominal aortic aneurysm. 6. right common ileac aneurysm. procedures performed during hospitalization: upper gastrointestinal endoscopy x2 with chemical cautery. condition on discharge: the patient is discharged to home in good condition. one of her relatives will be moving in with her home permanently to help care for her. patient is to followup with her primary care physician. , m.d. dictated by: medquist36 procedure: endoscopic control of gastric or duodenal bleeding endoscopic control of gastric or duodenal bleeding other irrigation of (naso-)gastric tube diagnoses: thrombocytopenia, unspecified acute gastric ulcer with hemorrhage, without mention of obstruction atrial fibrillation cardiac pacemaker in situ abdominal aneurysm without mention of rupture syncope and collapse personal history of malignant melanoma of skin helicobacter pylori [h. pylori] 

Answer: The patient is high likely exposed to
