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: this is an 87 year old man with a history of etoh abuse, significant for drinking six or seven scotches per night, history of dilated cardiomyopathy, ejection fraction of 30 percent. he awoke two nights prior to admission, had four episodes of brownish ground coffee emesis. the patient was admitted on . no complaints of abdominal pain or retching. he also noted bright red blood, some dizziness, no shortness of breath and no weakness. he went to his primary care physician who sent the patient to the emergency department. in the emergency department, he had two more episodes of coffee ground emesis. nasogastric lavage attempted but it was aborted secondary to a nosebleed. the patient's hematocrit had dropped from 44.0 percent to 35.0 percent. the patient was therefore admitted to the unit for evaluation of upper gastrointestinal bleed. past medical history: etoh history. hypertension. chronic atrial tachycardia with a baseline heart rate of 100 to 110. gout. questionable atypical seizure disorder. dementia. allergies: aspirin sensitivity, nosebleeds. medications on admission: 1. toprol xl 12.5 mg p.o. once daily. 2. digoxin 0.125 mg p.o. once daily. 3. hydrochlorothiazide 25 mg once daily. 4. allopurinol 300 mg once daily. 5. mysoline 250 mg once daily. 6. multivitamin. social history: the patient lives with wife, retired, history of multiple jobs. history of drinking six or seven scotches per day. nonsmoker. physical examination: the patient's vital signs are unremarkable except for heart rate of 108. physical examination is notable for positive dupuytren's contracture. no evidence of hepatosplenomegaly on examination. hospital course: the patient was admitted for observation. hematocrit was stable in the mid 30s overnight. he underwent esophagogastroduodenoscopy which was negative for any source of acute bleed. it was positive for what appeared to be friable esophageal mucosa consistent with barrett's esophagitis as well as a c line which was displaced proximally. no biopsies were taken. at this point, the patient was treated with protonix and discharged home on p.o. protonix with follow-up with his primary care physician in one to two weeks with plans for referral for an outpatient esophagogastroduodenoscopy for biopsies to confirm the visual appearance of barrett's esophagitis. the patient is to follow-up in six to eight weeks. medications on discharge: the patient will be discharged on all his original outpatient medications in stable condition with addition of protonix 40 mg once daily. 1. toprol xl 12.5 mg p.o. once daily. 2. digoxin 0.125 mg p.o. once daily. 3. hydrochlorothiazide 25 mg once daily. 4. allopurinol 300 mg once daily. 5. mysoline 250 mg once daily. 6. multivitamin. 7. protonix 40 mg p.o. once daily. discharge diagnosis: barrett's esophagitis. major procedures: esophagogastroduodenoscopy. , procedure: other endoscopy of small intestine diagnoses: other primary cardiomyopathies congestive heart failure, unspecified unspecified essential hypertension acute kidney failure, unspecified gout, unspecified other convulsions other specified cardiac dysrhythmias alcohol abuse, continuous barrett's esophagus 

Answer: The patient is high likely exposed to
