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: 1. emphysema. 2. ocular stroke. 3. renal cyst removal. 4. appendectomy. 5. leg surgery secondary to a motor vehicle accident as a child. 6. throat polyps. 7. diabetes mellitus. allergies: the patient states allergies to aspirin and tape. admission medications: 1. singulair 10 mg q.d. 2. advair 250/50 two puffs b.i.d. 3. lipitor 10 mg q.d. 4. glucophage 1,000 mg t.i.d. 5. potassium chloride 10 meq b.i.d. 6. sulfasalazine 500 mg b.i.d. 7. lasix 40 mg b.i.d. 8. nitroglycerin p.r.n. 9. tylenol with codeine q. four hours p.r.n. 10. zyprexa 10 mg q.h.s. 11. glipizide 10 mg b.i.d. 12. coumadin 7.5 mg three times a week, 10 mg four times a week. laboratory/radiologic data: white count 10.3, hematocrit 36.4, platelets 261,000. sodium 137, potassium 4.8, chloride 104, c02 25, bun 22, creatinine 1.2. social history: the patient lives at home with his son and his wife. hospital course: the patient was admitted to the on directly to the cardiac catheterization laboratory. the catheterization showed severe aortic stenosis with an aortic valve area of 0.63 cm square and no coronary disease. physical examination in the catheterization laboratory: heart rate 72, sinus, blood pressure 150/74, respiratory rate 16, alert and oriented times three. respiratory: lungs clear to auscultation anteriorly. cardiovascular: regular rate and rhythm with a iii/vi systolic ejection murmur. abdomen: soft, nontender. extremities: right groin with minimal staining on the dressing. no hematoma. no bruit. positive palpable distal pulses with no edema. following catheterization, the patient was seen by cardiothoracic surgery and was anticipated to go to the operating room on the following morning. however, on the following morning, the patient had a white blood cell count of 18.6 and his surgery was cancelled while blood, sputum, and urine were cultured. simultaneously, the patient was seen in the vascular laboratory for carotid duplexes which showed no significant stenoses in either the right or the left carotids. all culture data came back negative and the patient was rescheduled for aortic valve replacement on . on , the patient was brought to the operating room, at which time he underwent an aortic valve replacement with a #21 st. jude valve. please see the or report for full details. in summary, the patient tolerated the procedure well and he was transferred from the operating room to the cardiothoracic intensive care unit following the surgery. the patient did well in the immediate postoperative period. his anesthesia was reversed. he was weaned from the ventilator and successfully extubated on postoperative day number one. the patient remained hemodynamically stable off all iv medications. his chest tubes were removed and he was transferred to the floor for continuing postoperative care and cardiac rehabilitation. , m.d. dictated by: medquist36 procedure: extracorporeal circulation auxiliary to open heart surgery angiocardiography of left heart structures left heart cardiac catheterization coronary arteriography using a single catheter open and other replacement of aortic valve diagnoses: diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled aortic valve disorders other emphysema long-term (current) use of anticoagulants 

Answer: The patient is high likely exposed to
