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: the patient is a 72 year old gentleman with a past medical history significant for coronary artery disease, status post mibi in , which showed no perfusion defect and an ejection fraction of 59% and recent admission to in late , for choledocholithiasis with stone removal via endoscopic retrograde cholangiopancreatography, who was scheduled to have an outpatient cholecystectomy, who presented to the on , with fatigue secondary to an upper gastrointestinal bleed. the patient also did report melena at home, however, there was no shortness of breath or associated chest pain. the patient denies any hematemesis. he also denies any abdominal pain. the patient is on aspirin at home. there is no history of alcohol use. the patient's discharge hematocrit from his admission was 36.7. in the emergency department, it was found to be 13.3. in the emergency department, the patient was mentating appropriately. nasogastric lavage showed approximately 25cc of bright red blood. electrocardiogram also showed some inferior st depressions as well. he was transfused, given ampicillin, gentamicin and flagyl and admitted to the hospital. past medical history: 1. coronary artery disease with negative mibi on . 2. hypertension. 3. choledocholithiasis, status post sphincterotomy and stone removal on , here in this institution. he was discharged on a seven day course of levofloxacin after that admission. allergies: he has no known drug allergies. medications on admission: 1. aspirin 325 mg once daily. 2. lopressor 50 mg three times a day. 3. hydrochlorothiazide 25 mg once daily. 4. morphine p.r.n. family history: significant for no history of gastric or gastrointestinal cancer. social history: he lives with his wife in . no alcohol and no tobacco. physical examination: on admission, his vital signs revealed a temperature of 99.6, blood pressure 144/57, pulse 106, oxygen saturation 99% in room air. in general, he was pale, fatigued, no respiratory distress. head, eyes, ears, nose and throat examination - he had conjunctival pallor, dry mucous membranes, nasogastric tube in place. neck - he had flat jugular venous distention, supple, no lymphadenopathy. his chest was clear to auscultation bilaterally. his cardiac examination showed tachycardia but regular. he had no murmurs. his abdomen was soft, no tender to palpation, no hepatosplenomegaly. his extremities were cool. his pedal pulses were palpable, and there was no edema. neurologically, he was grossly intact. laboratory data: on admission, laboratories were significant for an elevated white blood cell count of 25.9, hematocrit 13.3 down from 36.7 on , platelet count 400,000. chem7 was essentially normal. first set of cardiac enzymes were significant for a ck of 150 with a mb of 14.0 and troponin of 0.21. he also had elevated alt of 723, ast 393, and total bilirubin of 1.8. he had an amylase of 85, lipase 96 and alkaline phosphatase 120. he had normal coagulation studies and a negative urinalysis. his electrocardiogram as mentioned showed sinus tachycardia and he 0. depressions in the lateral leads. he also had q waves in the inferior leads which were old. hospital course: the patient was admitted to the medical intensive care unit for diagnosis of upper gastrointestinal bleed. also, the patient was having a non st segment elevation myocardial infarction secondary to demand and anemia. the patient also had an elevated white blood cell count. the patient's hematocrit was stabilized. he was transfused with four units of packed red blood cells. he was started on ampicillin, gentamicin and flagyl for presumed cholangitis in the setting of his elevated white blood cell count. his aspirin and beta blockers were held as he was having active bleeding and it was felt that his non st segment elevation myocardial infarction was secondary to demand and anemia. the patient was started on protonix 40 mg intravenously twice a day. he was seen by the gastroenterologist. on endoscopic retrograde cholangiopancreatography, they found a longitudinal localized tear of the mucosa with stigmata of recent bleeding at the gastroesophageal junction suggestive of either esophagitis or - tear. they also performed an endoscopic retrograde cholangiopancreatography. of note, the ampullary fullness that was seen on previous endoscopic retrograde cholangiopancreatography from his admission was no longer present. they were able to cannulate the biliary tree without difficulty. there was no evidence of purulent discharge. there was no stone appreciated at all. there was no bleeding at the time of previous endoscopic retrograde cholangiopancreatography. thus, it was felt that the most likely source of his upper gastrointestinal bleed was the esophagitis versus - tear. there was no active bleeding at that time. the patient's hematocrit did remain stable after transfusion. he had no further episodes of active bleeding. the patient did rule in for a non st segment elevation myocardial infarction with a peak troponin of 0.99. a repeat echocardiogram was done which was done which was essentially unchanged from an echocardiogram in . the patient's aspirin was held but, once he was hemodynamically stable,, he was restarted on his beta blocker and his hydrochlorothiazide for his hypertension. although there was no purulent discharge from the biliary tree, the patient was continued on levofloxacin/flagyl in favor of ampicillin/gentamicin/flagyl and he will complete a seven day course of levofloxacin/flagyl. of note, prior to the endoscopic retrograde cholangiopancreatography while the patient was in the medical intensive care unit, he did have an episode of flash pulmonary edema secondary to his demand ischemia and non st segment elevation myocardial infarction in the setting of volume repletion with blood and intravenous fluids. this required a short period of intubation. the patient was extubated successfully with no further respiratory complaints. the patient was restarted as mentioned back on his antihypertension medications. he was put on a once daily toprol xl in favor of his three times a day lopressor at home and was restarted on his hydrochlorothiazide. he was instructed not to take aspirin any longer and to avoid nonsteroidal anti-inflammatory drugs. he was told to use tylenol for pain control. his transaminitis resolved on its own and the patient will need to follow-up with dr. for outpatient scheduling of cholecystectomy. the patient was evaluated by physical therapy on the day of discharge. they felt he had no acute physical therapy needs and he was safe to ambulate without assistance. condition on discharge: fair. discharge status: to home. discharge diagnoses: 1. upper gastrointestinal bleed secondary to esophagitis versus - tear. 2. non st segment elevation myocardial infarction secondary to demand and anemia. 3. hypertension. 4. history of choledocholithiasis in need of cholecystectomy. medications on discharge: 1. pantoprazole 40 mg p.o. once daily. 2. levofloxacin 500 mg p.o. once daily for a total of seven days. 3. metronidazole 500 mg p.o. three times a day for a total of seven days. 4. hydrochlorothiazide 25 mg p.o. once daily. 5. toprol xl 50 mg once daily in place of his lopressor. 6. colace 100 mg p.o. twice a day. discharge instructions: the patient was told to avoid aspirin and nonsteroidal anti-inflammatory drugs. the patient will need to follow-up with dr. of gastroenterology in one to two months and also with dr. of general surgery for cholecystectomy. the patient was also instructed to follow-up with his primary care physician in two weeks. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube transfusion of packed cells endoscopic retrograde cholangiopancreatography [ercp] diagnoses: subendocardial infarction, initial episode of care unspecified essential hypertension iron deficiency anemia secondary to blood loss (chronic) acute respiratory failure hemorrhage of gastrointestinal tract, unspecified esophagitis, unspecified cholangitis gastroesophageal laceration-hemorrhage syndrome 

Answer: The patient is high likely exposed to
