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 an 85-year-old female who was referred to dr. with known aortic stenosis. she had previously had an outpatient cardiac catheterization in . in , she had left arm heaviness and numbness along her chest and back. she was admitted to the where her cardiac enzymes were negative and her thallium test was negative for ischemia, but an echocardiogram showed an ejection fraction of 55% with severe aortic stenosis. she was referred to dr. for aortic valve replacement. past medical history: question of peptic ulcer disease/gastroesophageal reflux disease past surgical history: appendectomy. allergies: she has no known drug allergies. medications on admission: her only medication was aspirin 81 mg p.o. once per day. pertinent laboratory values on presentation: preoperative laboratory work was as follows; white blood cell count was 4.5 and hematocrit was 37.6. prothrombin time was 12.1, partial thromboplastin time was 23.7, and inr was 1. platelet count was 215,000. the patient was in a sinus rhythm at a rate of 86. pertinent radiology/imaging: carotid studies in showed minimal plaque bilaterally with less than 40% carotid stenosis. a preoperative electrocardiogram revealed a sinus rhythm with no atrial ectopy present at this time, but could not rule out old inferior myocardial infarction. hospital course: the patient was referred to dr. . on , the patient underwent limited access aortic valve replacement with a 19-mm pericardial - tissue valve. she was transferred to the cardiothoracic intensive care unit in stable condition on a neo-synephrine drip at 0.5 mcg/kg per minute and titrated propofol drip. on day one, the patient had been extubated. the patient was saturating 96% on a face mask. she received her perioperative antibiotics. blood pressure was 122/53 with a central venous pressure of 7. she was on a nitroglycerin drip at 1. her white blood cell count was 11 and hematocrit was 31. sodium was 139, potassium was 3.9, chloride was 107, bicarbonate was 23, blood urea nitrogen was 11, creatinine was 0.7, and blood glucose was 109. the patient was also on an insulin drip at 2. her lungs were clear. there were bowel sounds. the examination was benign. the patient began diuresis and had been extubated without any difficulty. she was seen by case management. on day two, the patient was alert and awake with a heart rate in sinus rhythm at 108. her blood pressure was 137/53 with good urine output. she was started on lopressor and lasix diuresis. blood urea nitrogen was 21. creatinine was 0.7. potassium was 3.6. temperature maximum was 99.2. her lungs were clear. her sternum was stable. she began her beta blockade. her h2 blockers were stopped. of note, her platelet count continued to drop to 92,000 on day one and then 62,000 on day two. her platelet count was rechecked. a heparin-induced thrombocytopenia panel was sent, and all heparin was stopped. the central venous line was also discontinued. the patient was responsive and doing very well and was transferred out to two on and was also seen by physical therapy. her sternal incision was dry. pacing wires remained in place. she was monitored on the floor, and ambulation was begun. she was switched over to oral percocet and encouraged to ambulate with the physical therapist and the nurse day three. she was in a sinus rhythm with a heart rate of 90 to 100 with a blood pressure of 98/45. she was saturating 94% on room air. her blood sugar was 132. she was making good urine output. her platelet count slightly from 62,000 to 67,000. white blood cell count was 11, and hematocrit was 31. she began her beta blockade as well as lasix diuresis. she was continued on protonix. she was alert and oriented. she continued to work with physical therapy and was seen again by case management to work for a plan for discharge. on day four, she had a temperature maximum of 98.8. she was in a sinus rhythm at 85. her blood pressure was 103/60. her blood sugar was in the range of 97 to 155. her white blood cell count dropped to 7.1. her hematocrit was 26.4. platelet count was holding at 67,000. blood urea nitrogen was 23, and creatinine was 0.7. her heart was regular in rate and rhythm. her lungs were clear. her incision was clean, dry, and intact. she remained on an insulin sliding-scale with plans to discharge her to home with services. she was transfused one unit of packed red blood cells for her hematocrit and was receiving oral pain medications. she was walking independently on the floor. discharge planning included having her see her doctor for her wound check and to follow up there also. discharge status: the patient was discharged to home with her daughter on . discharge diagnoses: 1. status post limited access aortic valve replacement with pericardial tissue valve. 2. gastroesophageal reflux disease. 3. question peptic ulcer disease. 4. decreased vision in the left eye. medications on discharge: (discharge medications were as follows) 1. aspirin 325 mg p.o. once per day. 2. lasix 20 mg p.o. twice per day (times one week). 3. potassium chloride 10 meq two tablets p.o. twice per day (for one week). 4. colace 100 mg p.o. twice per day (for 30 days). 5. tylenol 325 mg p.o. q.4h. as needed. 6. percocet 5/325 one to two tablets p.o. q.4h. as needed (for pain). 7. metoprolol 50 mg p.o. twice per day (times 30 days). 8. protonix 40 mg p.o. once per day. 9. magnesium hydroxide 40-mg oral suspension 30 ml p.o. q.6h. as needed for one month (for constipation). discharge disposition: the patient was discharged to home. discharge instructions/followup: 1. the patient was given instructions to follow up with her primary care physician in . 2. the patient was to follow up with dr. in four weeks in for her visit. , m.d. dictated by: medquist36 procedure: extracorporeal circulation auxiliary to open heart surgery open and other replacement of aortic valve with tissue graft diagnoses: aortic valve disorders 

Answer: The patient is high likely exposed to
