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 a 76 year old male with a past medical history of a right-sided cerebrovascular accident, coronary artery disease, status post coronary artery bypass graft, hypertension, lower gastrointestinal bleed on coumadin who was sent to from for right upper quadrant pain, nausea, vomiting and change in mental status. the patient denies any fevers, chills, chest pain, or shortness of breath. he was recently discharged from . he was here from to , for a right hemisphere watershed stroke. he had diarrhea that was nonbloody during that admission while he was on coumadin. previously the patient has had projectile vomiting and bloody diarrhea at the rehabilitation facility while on coumadin, so the coumadin was discontinued at . the patient in the emergency room had systolic blood pressures in the 200s and elevated liver function tests and lipase. a gallbladder ultrasound showed acute cholecystitis. his troponin was also elevated at 0. elevation son his electrocardiogram. surgery was consulted. the patient was made npo and given levofloxacin and flagyl intravenously, intravenous fluids and admitted to medicine for further care. past medical history: 1. cerebrovascular accident. he had a right hemisphere watershed infarct on . he had a right carotid artery total occlusion, and he had a 79% left internal carotid artery stenosis. 2. lower gastrointestinal bleed on coumadin. 3. hypertension. 4. patent foramen ovale by echocardiogram in . there was an ejection fraction of 40 to 45%. he had apical akinesis, 1+ aortic regurgitation, 1+ tricuspid regurgitation. 5. coronary artery disease, status post coronary artery bypass graft 26 years ago. 6. chronic obstructive pulmonary disease. 7. he had had a left groin hematoma. medications on admission: 1. ativan 2 mg p.o. q.i.d. 2. aspirin 325 q.d. 3. aggrenox 1 tablet b.i.d. 4. coumadin had been discontinued on . 5. lisinopril 30 q.d. 6. lipitor 40 q.d. 7. protonix 40 q.d. 8. iron tablets. 9. neurontin 300 b.i.d. 10. tylenol prn. allergies: penicillin causes a rash. social history: he lives with his wife in clinic. he has a 100 pack year tobacco history. he quit in . he is a retired homicide detective. family history: he has a sister with disease. physical examination on admission: his temperature was 98.8, blood pressure was 193/95 which improved to 177/79, heart rate was 96, respiratory rate was 16. he was 98% on room air. in general he was awake and alert. he had dysarthria. head, eyes, ears, nose and throat: he has a left facial droop, otherwise he was anicteric. mucous membranes were dry. neck was supple. he had bilateral bruits. his jugulovenous distension was at 8 cm. cardiovascular, he had regular rate and rhythm, normal s1 and s2. he had a i/vi holosystolic murmur heard best at the right upper sternal border. lungs were clear to auscultation bilaterally. abdomen was soft. he had right upper quadrant tenderness with palpation. there was no rebound, no guarding. extremities: there was no cyanosis, clubbing or edema. he had 2+ pulses bilaterally. neurologic, he had dysarthria, he had good comprehension. he had a left-sided facial droop. his left upper extremity strength was . the lower extremity strength was 4+/5. otherwise strength was throughout intact. he did have a pronator drift on the left. his toes were downgoing bilaterally. laboratory data on admission: complete blood count, white count 14.5, hematocrit 40.9, platelets were 297. his coags were within normal limits. his chem-7 was remarkable only for a creatinine of 1.5 which was slightly elevated from his baseline of 1.2 to 1.4. his first set of cardiac enzymes, his creatinine kinase was 73, mb was 2. his troponin was 0.88. his liver function tests were significant for an alt of 57, ast of 93, alkaline phosphatase 50 to 55, total bilirubin 1.6, amylase was 920 and lipase was 2,025. liver ultrasound showed distended thickened gallbladder with no pericholecystic fluid, was consistent with stones and sludge, there was no ductal dilatation, there was son sign. this was overall consistent with acute cholecystitis. chest x-ray was clear. electrocardiogram was 94 beats/minute, normal interval and axis. he has evidence of prior enteric septal infarct, low voltage throughout. there were no ischemic st or t wave changes compared to an old electrocardiogram. plan: the patient was admitted to medicine. hospital course: (by systems) gastrointestinal: 1. acute cholecystitis - the patient was seen by the surgery service. it was felt that he was too high risk of an operative candidate, so he was made npo and continued on intravenous fluids and intravenous levaquin and flagyl. once the patient was able to tolerate oral intake, he was changed over to oral antibiotics and he will complete a 14 day course of antibiotics. 2. gallstone pancreatitis - the patient , m.d. dictated by: medquist36 procedure: parenteral infusion of concentrated nutritional substances other endoscopy of small intestine enteral infusion of concentrated nutritional substances endoscopic removal of stone(s) from biliary tract endoscopic sphincterotomy and papillotomy cholecystectomy transfusion of packed cells other cholecystostomy other gastrostomy other closed [endoscopic] biopsy of biliary duct or sphincter of oddi diagnoses: coronary atherosclerosis of native coronary artery congestive heart failure, unspecified unspecified essential hypertension acute kidney failure, unspecified unspecified protein-calorie malnutrition chronic airway obstruction, not elsewhere classified hemorrhage of gastrointestinal tract, unspecified acute pancreatitis calculus of gallbladder with acute cholecystitis, without mention of obstruction 

Answer: The patient is high likely exposed to
