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: allergies: the patient has no known drug allergies. medications on admission: 1. coumadin. 2. lopressor 100 mg b.i.d. 3. amiodarone 200 mg daily. past medical history: the patient had a cardiovascular accident without residual, hypertension, osteoarthritis, copd, mi, and chronic atrial fibrillation. past surgical history: history included coronary artery bypass grafting in of this year. social history: the patient is a smoker, nondrinker. the patient was independently ambulating prior to admission. physical examination: examination showed vital signs stable. heent: examination was unremarkable. heart: irregular rate and rhythm with a median sternotomy incision, well healed. lungs: lungs were clear to auscultation. abdomen: abdomen was soft, nontender. abdominal aneurysm was nonpalpable. extremities: extremities showed femoral pulses intact. the right dp was dopplerable. the right pt was palpable. the left pedal pulses were palpable, both dp and pt. rectal: rectal examination revealed increased prostate size, guaiac negative. hospital course: the patient was admitted to the preoperative holding area on . he underwent abdominal aortic aneurysm repair with an aortobifemoral bypass graft with a re-implanted artery with pft. the patient tolerated the procedure well. the patient was transferred to the pacu in stable condition. on postoperative day #1, he remained hemodynamically stable. the lopressor was increased to manage his hypertension. anticoagulation was begun for the chronic atrial fibrillation. he was converted to a pca. on postoperative day #3 abdominal examination was unremarkable. there were bowel sounds present, but no flatus. pos were held. the pa catheter was converted to cvl. on postoperative day #3, the patient needed continued diuresis and the cvl was changed to a left subclavian without difficulty. the post change line revealed no pneumothorax. on , he had the onset of abdominal discomfort with tachycardia, tachypnea with fluid overload. the kub showed dilated small bowel. the ekg was without acute changes. the hematocrit dropped and he required transfusion. gastrointestinal department was consulted concerning a gastrointestinal bleed. he underwent upper and lower endoscopy without any evidence of bleeding or ischemic bowel changes or gastroduodenal ulcerations or bleeding. he was required to be re-intubated. he was transfused and serial ck-mb were obtained, which were flat. the ekg were without acute ischemic changes. the patient's bun and creatinine bumped to 3.8. he went into acute renal failure. renal service was consulted. he was begun on tpn. nasogastric tube feed was placed on tube feedings. renal continued to follow the patient and by the creatinine was back a baseline. he was diuresing adequately. on , postoperative day #13, the patient had an elevated temperature. he continued to remain intubated. bronchoscopy was done, which showed a left lower lobe and right upper lobe pneumonia. cultures were obtained both of blood, sputum, and c. difficile. the c. difficile was negative. blood cultures revealed no growth. sputum grew gram-negative rods, which were consistent with klebsiella. he was started on levofloxacin and flagyl empirically. he was continued on this for a full 14-day course on , the et tube was changed with bronchoscopy. tpn was discontinued on the 29th. he was continued on his tube feeds. on postoperative day #19, date , the patient was noted to be confused and somnolent. head ct was obtained, which was initially read as negative, but, after further review it was determined that the patient had an intracranial bleed. he remained intubated. he was finally extubated on and transferred to the vicu on . he extubated ng tube on . the department of otolaryngology was requested to see the patient regarding assessment for aspiration. he tolerated liquids well without signs of aspiration. recommendations were to continue with clear and full liquids and to monitor the patient for aspiration, put the patient on aspiration precautions. the patient was transferred to the regular nursing floor on . he continued to progress. the department of otolaryngology service saw the patient on . he had no aspiration. the diet could be advanced to pureed diet, but no thick-thick foods, i.e. oatmeal or mash potato consistency foods. coumadinization was restarted. he was begun on 7.5 mg. this dosing was according to the pt inr goal of 2.0 to 2.5 for chronic atrial fibrillation. the patient was re-evaluated by the department of physical therapy. they felt that he would require a short-term stay in rehabilitation for ambulation and conditioning. case management made referrals to the appropriate rehabilitation. the patient was transferred to rehabilitation on in stable condition. discharge medications: 1. coumadin dosing according to inr. goal is 2.0 to 2.5. 2. heparin subcutaneously 5000 units b.i.d. 3. zantac 150 mg b.i.d. 4. nitropaste 2 inches q.6h to chest wall; hold for systolic blood pressure of less than 100. 5. lopressor 125 mg q.6h. 6. norvasc 10 mg q.d. 7. clonidine patch 0.3 mcg q.friday. 8. captopril 100 mg t.i.d. discharge diagnoses: 1. abdominal aortic aneurysm with repair. 2. abdominal hematoma secondary to low platelet count, heparinization and anticoagulation resolved. 3. blood loss transfused corrected. 4. klebsiella pneumonia treated. 5. atn secondary to hypotension. 6. shock liver, improving. 7. htn controlled. 8. mental status changes secondary to intracranial bleed, resolved. discharge instructions: the patient should followup with dr. post discharge from rehabilitation. primary care physician can manage the coumadinization for atrial fibrillation. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for 96 consecutive hours or more parenteral infusion of concentrated nutritional substances other endoscopy of small intestine insertion of endotracheal tube enteral infusion of concentrated nutritional substances aorta-iliac-femoral bypass flexible sigmoidoscopy other repair of vessel diagnoses: thrombocytopenia, unspecified acute kidney failure with lesion of tubular necrosis acute posthemorrhagic anemia chronic airway obstruction, not elsewhere classified atrial fibrillation hematoma complicating a procedure abdominal aneurysm without mention of rupture pneumonia due to klebsiella pneumoniae iatrogenic cerebrovascular infarction or hemorrhage 

Answer: The patient is high likely exposed to
