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: past medical history: coronary artery disease, status post left anterior descending stent in and a recent admission from to for chest pain and pulmonary edema which required intubation and a cardiac catheterization with a stent to the right coronary artery. the patient's catheterization course at that time was complicated by hypotension requiring brief dopamine drip. the patient was quickly weaned off and discharged on to rehabilitation. on the night prior to admission the patient developed shortness of breath and chest pain. he was then transferred to where he was treated with intravenous lasix and rule out for myocardial infarction was begun. of note, the patient had not received any lasix after discharge from on and had a 7 pound weight increase at the time. past medical history: congestive heart failure with ischemic cardiomyopathy, moderate left ventricular systolic dysfunction, apex akinetic, septum hypokinetic. coronary artery disease, status post left anterior descending stent in and status post an right coronary artery stent in . status post a ddd- pacer for bradycardia, increased cholesterol, hypertension and chronic renal insufficiency, diastolic dysfunction for vascular disease, status post an aortobifemoral bypass, chronic obstructive pulmonary disease, back pain, history of sundowning, glaucoma, gout, prostate carcinoma. social history: lives with his wife who has , two daughters, occasional alcohol use. family history: noncontributory. allergies: no known drug allergies. review of systems: positive for constipation. physical examination: on admission temperature 96.7, blood pressure 112/58, pulse 65 sating 100% on two liters. general: elderly russian speaking male in no acute distress. head, eyes, ears, nose and throat shows moist mucous membranes, jugular venous distention with increase to the ear, lungs are clear to auscultation bilaterally. cardiovascular: distant heart sounds. regular rate and rhythm with a 2/6 systolic murmur in the left upper sternal border without radiation. abdomen is soft, nontender, nondistended, positive bowel sounds. liver is palpable 2 to 3 cm below the costal margin. extremities showed 2+ edema bilaterally. laboratory: white count 15.7, hematocrit 36.5, platelets 319, potassium 5.8, bun 38, creatinine 1.7, albumin 2.9, tsh 9.03 wit a normal free t4. troponin .07 and .1. medications on transfer: 1. aspirin 325 mg once a day. 2. lopressor 25 mg twice a day. 3. amiodarone 200 mg q day. 4. protonix 40 mg once a day. 5. lipitor 40 mg once a day. 6. captopril 25 mg three times a day. 7. plavix 75 mg once a day. 8. colace 100 mg twice a day. 10. bisacodyl 10 mg once a day. hospital course: 1. congestive heart failure. the patient was felt to be fluid overload and congestive heart failure exacerbation. diuresed with nitrocor and lasix and dopamine transiently. on the patient developed hypotension with systolic blood pressures down to the 40's and 50's and became hypoxic requiring 100% non-rebreather. the patient was subsequently transferred to the ccu for further care. while in the ccu the patient's blood pressure was maintained with dopamine and neo-synephrine initially and then changed to dobutamine and nitroprusside. a swann ganz catheter was placed for hemodynamic tailored therapy. the patient initially showed values of a cardiac output of 2.6 and an index of 1.6. his wedge was 10. the patient was felt therefore to be over-diuresed and intravenous fluids were started with a goal of 12 to 13, 5 liters of fluids were given. the patient subsequently improved while on dobutamine and nitroprusside. nitroprusside was weaned off secondary to the duration of treatment. the nesiritide was restarted. on the dopamine was weaned off and the patient was restarted on ace inhibitor which was titrated upward to captopril 75 mg three times a day. the patient was then diuresed gently. on the swann ganz catheter was discontinued and the patient was weaned of the nesiritide. his final swann numbers showed a cardiac output of 2.4 with an index of 1.5. following the hypotensive episodes requiring his transfer to the ccu the patient developed heme positive stools with an increase lactate and increased amylase and complaints of abdominal pain. ct scan done showed thickening of the ascending colon. surgery was consulted regarding possible ischemic colitis. they felt that there was no need for surgery at this time especially based on patient's cardiac status. treatment was bowel rest, tpn nutrition and serial exams. the patient was treated with zosyn and flagyl. at the time the patient was transferred to the floor he was off antibiotics. however, abdominal exam still showed distension with hypoactive bowel sounds. on transfer to the floor the patient appeared fluid overloaded once again, the patient was therefore restarted on astreotide and lasix and captopril was reduced in order to keep the patient's systolic blood pressure greater than 90 while on nitrocor therapy. the patient subsequently had an episode of pulselessness and possibly hypotension. it was felt at this time that treatment was most likely futile. a family meeting was called for discussion of code status. 2. code status. family meeting was held and the goals of therapy were discussed. the patient was unable to contribute to the discussion of future care secondary to delirium. the patient's daughter and son were present at this meeting. initially a decision to make the patient dnr/dni was reached, subsequent comfort care was decided. 3. delirium. from day one of the hospital stay the patient suffered from a delirious state. he had a history of sundowning however his delirium seemed to be constant, it was thought secondary to his medical problems most likely to his congestive heart failure and very low cardiac output. initially treated with zyprexa at bedtime with haldol p.r.n. however, there is little improvement post ccu stay and hypotension. the patient's mental status was depressed and he remained somnolent for many days prior. following a decision of dnr/dni comfort care only when care was withdrawn the patient seemed to wake up however, remained quite delirious. 4. gastrointestinal. ischemic colitis. the patient was treated conservatively with bowel rest, tpn. decision was made to allow food to be given to the patient after he was comfort care only if he so desired. palliative care consult was called to help with management of end-of-life issues. the remainder of this hospital course will be dictated in a subsequent addendum. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified parenteral infusion of concentrated nutritional substances injection or infusion of

Answer: The patient is high likely exposed to
