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: history included cad and status post cabg. he also had prosthetic valve placed and trigeminal neuralgia decompression. laboratory data: labs on admission revealed the following: white count 7.5, hematocrit 40.7, platelet count 260,000, pt 14.4, ptt 35.1, inr 1.4. the patient was admitted to the surgical intensive care unit and a ventricular drain was placed. the patient was monitored closely. the department of cariology saw the patient in the intensive care unit and recommended holding all beta blockers and restarting the amiodarone. the patient remained intubated and sedation for two days. on , all sedation was discontinued and the patient was showing some signs of improvement. pupils were 3-mm down to 2 -mm and briskly reactive. the patient was following simple commands, showing two fingers. the patient had repeat head ct on , which showed no change in the fourth ventricle. the patient had an episode of hypoxia on . the patient had a ct angiogram, which was negative for pe. the patient had spiked a temperature on and was started on levofloxacin for gram-negative rods, sputum culture. the patient continued to be followed by the cardiology service. the patient went back into atrial fibrillation. the department of cardiology recommended electrocoagulation, which was done. the patient converted to normal sinus rhythm and has remained in normal sinus rhythm to date. the patient was extubated on and tolerated that well. he was awake, alert, oriented, following commands, moving all extremities strongly. he was transferred to the regular floor on . he had a swallow evaluation, which he failed. he had a g tube placed. vital signs have remained stable. he has been afebrile. he finished a 10-day course of levofloxacin for klebsiella pneumonia. he current is afebrile. he was seen by physical therapy and occupational therapy and found to require rehabilitation prior to discharge home. medications on discharge: 1. prevacid 30 mg per ng tube q.12h. 2. levofloxacin discontinued. 3. captopril 25 mg per ng tube q.8h. 4. nystatin swish and swallow 5 cc q.6h. 5. celebrex 200 mg per ng tube q.day. 6. lopressor 25 mg p.o.b.i.d. 7. amiodarone 200 mg p.o. ng tube b.i.d. 8. tums 500 mg per ng tube b.i.d. 9. tylenol 650 q.4.h. p.r.n. condition on discharge: the patient's condition was stable at the time of discharge. follow-up care: the patient will followup with dr. in 10 to 14 days and with his cardiologist as needed postoperatively. , md dictated by: medquist36 procedure: venous catheterization, not elsewhere classified continuous invasive mechanical ventilation for 96 consecutive hours or more insertion of endotracheal tube enteral infusion of concentrated nutritional substances percutaneous [endoscopic] gastrostomy [peg] intravascular imaging of intrathoracic vessels venous catheterization, not elsewhere classified continuous invasive mechanical ventilation for 96 consecutive hours or more insertion of endotracheal tube enteral infusion of concentrated nutritional substances percutaneous [endoscopic] gastrostomy [peg] intravascular imaging of intrathoracic vessels diagnoses: pneumonia, organism unspecified obstructive hydrocephalus aortocoronary bypass status atrial flutter intracerebral hemorrhage acute respiratory failure other and unspecified angina pectoris heart valve replaced by transplant 

Answer: The patient is high likely exposed to
