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 78-year-old female, with known ascending aortic aneurysm. the patient complains of recently shortness of breath with exertion and minimal epigastric indigestion with activity which resolves with rest. cardiac catheterization done showed an ejection fraction of 54 percent, with a mid-lad lesion of 30- 40 percent. chest mra in showed a 6.4 cm ascending aortic aneurysm. the patient had been originally scheduled for surgery in ; however, at that time her surgery was canceled due to an esophageal tear. as an outpatient, the patient had a repeat upper endoscopy which showed a well- healed tear. past medical history: hypertension. gerd. cataract. nephrolithiasis. ascending aortic aneurysm. status post cesarean section x 3. allergies: aspirin which causes gi upset. iv dye which causes shaking chills. shellfish which causes nausea and vomiting. preoperative medications: 1. hydrochlorothiazide 25 mg po qd. 2. atenolol 50 mg po qd. 3. milk of magnesia prn. social history: the patient smokes approximately a half pack per day with approximately 35-pack year. the patient denies etoh. she lives alone in rosalindale next door to her sister. ho course: the patient was taken to the operating room with dr. on for replacement of her aortic arch and her proximal descending aorta with an aorto- subclavian bypass and a vertebro-subclavian bypass. total cardiopulmonary bypass time was 214 minutes. crossclamp time 43 minutes. total circulatory arrest time was 50 minutes divided up into 3 intervals. postoperatively, the patient was transferred to the intensive care unit in stable condition on nitroglycerin and epinephrine drips. upon admission to the intensive care unit, the patient was noted to have a small amount of blood draining from bilateral ears. ent consult was obtained, and upon examination by the ent staff, it was noted that the patient had blood behind her eardrums but no perforation, unclear etiology. recommended antibiotic ear drops for 7 days and continued reassessment. the situation resolved, and the patient had no further issues. the patient had some labile hemodynamics immediately postop requiring correction of coagulopathy and transfusion of packed red blood cells, without significant chest tube output. the patient initially required increased peep for poor oxygenation. on postop day 1, the patient began to awaken, and it was felt that perhaps the patient had some mild right-sided weakness. at that time, the patient's goal blood pressure was increased, and the patient remained very sleepy for the next few days. eventually, fully awoke and was found to be neurologically intact. the patient was started on lasix with good diuresis. the patient was intermittently hypertensive due to stimulation. the patient was started on lopressor. continued to be on nitroglycerin. the patient intermittently had been on sodium nitroprusside which caused hypoxia, and this was discontinued. the patient was started on combivent inhalers with moderate improvement in her expiratory wheezes. on postoperative day 3, the patient had been placed on cpap which had tolerated well. towards the end of the day, the patient acutely became anxious, agitated and hypertensive, complaining that she was having trouble breathing. chest x- ray was obtained at that time which was unremarkable. the patient was placed back on with resolution of the incident. on postoperative day 3, cardiology consult was obtained for assistance in managing hypertension. it was recommended to continue aggressive diuresis and continue current medical therapy. the patient was weaned on mechanical ventilation and extubated initially with hemodynamic instability, hypertension and tachycardia which resolved. the patient remained extubated approximately 2-1/2 hours, at which time she became acutely agitated, short of breath and tachypneic, and quickly progressed to respiratory failure. the patient was emergently reintubated. it was felt that her failure was due to volume overload. the patient was continued to be aggressively diuresed. the patient was started on natrecor, as well as her lasix to aid in diuresis and help with hypertension. the patient's creatinine had slowly begun to rise and peaked at approximately 2.1. the patient's sputum from grew mrsa. the patient was started on iv vancomycin for treatment. the patient was started on tube feeds. the patient had several episodes of rapid atrial fibrillation for which she was started on amiodarone. all episodes were nonsustained. the patient underwent bronchoscopy which showed moderate secretions bilaterally which were aspirated, and moderate to severe malacia of the distal trachea. the patient continued to be aggressively diuresed and was extubated on , and due to the presence of tracheomalacia, the patient was extubated and placed on intermittent cpap which was gradually weaned off, as the patient continued diuresis. the patient underwent a swallowing evaluation on which showed no evidence of aspiration. the patient continued on her amiodarone for her atrial fibrillation. the patient was intermittently pleasantly confused which subsequently resolved. the patient developed an elevated white blood cell count on . the patient was pancultured. the patient's ua was positive, and urine culture was subsequently negative. the patient had been started on levofloxacin. repeat urine culture was sent on with results still pending. the patient's lasix was discontinued on due to rise in creatine and patient being below preop weight. on , the patient was transferred from the intensive care unit to the regular part of the hospital and began being screened for rehab. on , the patient was cleared for discharge to rehab. condition at discharge: t-max 97.6, pulse 75 in sinus rhythm, blood pressure 129/80, respiratory rate 18, room air oxygen saturation 93 percent. the patient's weight on was 68.5 kg, which was decreased from 69.3 on . laboratory data: white blood cell count 16.1, hematocrit 36.6, platelet count 687, sodium 144, potassium 4.1, chloride 106, bicarb 22, bun 51, creatinine 1.9, glucose 81. physical exam: neurologically, the patient was awake, alert, oriented x 3. no apparent deficit. her grip strength and her plantar flexion were equal bilaterally. heart was regular rate and rhythm without rub or murmur. respiratory - breath sounds were coarse with scattered rhonchi throughout. the patient had a moderately productive cough, but was not expectorating any sputum. gi - positive bowel sounds, soft, nontender, nondistended. the patient was tolerating a regular diet and having normal bowel movements. extremities - pulses were 2 plus bilateral radials and 2 plus bilateral dp and pt. extremities were warm and well-perfused without any evidence of edema. sternal incision was clean, dry and intact. the sternum was stable without any erythema or drainage. the right subclavian incision had mild tenderness to palpation in the area of the incision with a small amount of separation at the lateral portion of the incision which was scabbed over. there was no erythema, and there was no drainage. discharge medications: 1. amiodarone 200 mg po qd x 1 month. 2. combivent mdi 1-2 puffs q 6 h prn. 3. flovent 110 mcg mdi 2 puffs inhaled . 4. nicotine 14 mg patch 1 transdermally qd x 3 weeks. 5. protonix 40 mg po qd. 6. lopressor 25 mg po bid. 7. levofloxacin 250 mg po q 48 h x 6 days. discharge diagnoses: ascending aortic aneurysm. status post replacement of
