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: mr. is a 78-year-old male who recently underwent coronary artery bypass graft times four on at by dr. . the procedure was complicated by postoperative bleeding and left hemothorax necessitating repeat operation on which revealed oozing at the left internal mammary artery branch. the patient then had an uneventful postoperative course except for some postoperative atrial fibrillation. he was rate controlled, and anticoagulated, and discharged to rehabilitation on . he was admitted to hospital on with increased shortness of . bilateral thoracenteses were performed with approximately one liter per side obtained. he was placed on ceftriaxone for presumed pneumonia. echocardiogram on , showed vigorous left ventricular function, positive pericardial effusion, with tamponade physiology. he was transferred to for definitive treatment. past medical history: (the patient's past medical history is significant for) 1. coronary artery bypass graft times four (on with re-exploration for bleeding). 2. insulin-dependent diabetes mellitus. 3. hypertension. 4. hypothyroidism. 5. hypercholesterolemia. medications on transfer: (to ) 1. ceftriaxone 1 g intravenously once per day 2. avandia 4 mg by mouth once per day. 3. humalog sliding-scale. 4. aspirin 81 mg by mouth once per day. 5. amiodarone 200 mg by mouth once per day. 6. solu-medrol 60 mg intravenously q.12h. 7. synthroid 75 mcg by mouth once per day. 8. coumadin (was held). 9. natrecor 0.1 mcg/kg per minute. 10. albuterol and atrovent. medications on admission: (medications at home included) 1. lipitor 40 mg by mouth once per day. 2. cozaar 50 mg by mouth once per day. 3. atenolol 100 mg by mouth once per day. allergies: no known drug allergies. pertinent laboratory values on presentation: laboratories at hospital on (on the day of admission) revealed his white blood cell count was 21.8, his hematocrit was 25.9, and his platelets were 689. chemistries revealed his sodium was 134, potassium was 4.3, chloride was 101, bicarbonate was 22, blood urea nitrogen was 72, creatinine was 12.3, and his blood glucose was 209. his inr was 3.3. the patient had an inr of 4.4 on ; thus, his coumadin was held. physical examination on presentation: physical examination on admission revealed his temperature was 98.4 degrees fahrenheit, his heart rate was 93, his respiratory rate was 24, his blood pressure was 121/43, and his oxygen saturation was 92% on 6 liters nasal cannula. neurologically, the patient was alert and oriented. no apparent deficits. pulmonary examination revealed the patient had coarse sounds throughout with decreased bilateral sounds at the bases. cardiovascular examination revealed a regular rate and rhythm. no murmurs, rubs, or gallops. the abdomen was soft, nontender, and nondistended. normal active bowel sounds. the extremities were warm and without edema. the sternal incision was healing well, with a positive click, with cough, without drainage, a stable sternal wound. concise summary of hospital course: the patient had left thoracostomy tube placed, #28 french tube, to 27 cm, and 200 cc of fluid were initially drawn; 1800 with positional changes. a chest x-ray showed proper placement of left chest tube. cardiology was called on the day of admission for assessment of questionable tamponade physiology, and global left ventricular function was found to be normal without wall motion abnormalities. the patient had difficult windows; however, the study demonstrated small-to-moderate anterior and apical adhesions without right atrial collapse or right ventricular diastolic collapse. the patient continued to remain the cardiac surgery recovery unit and was found not to have tamponade physiology. the patient was started on vancomycin and levofloxacin. on , the patient continued to do well and was transferred to the floor. the patient had begun 3 mg of coumadin daily at night at that point. lopressor was increased on hospital day five, postoperative day 25, and the chest tube was removed. while on the floor, the patient did extremely well. the patient was ambulating well with physical therapy and was getting 2 mg of coumadin q.h.s. on the day of discharge, the patient had an inr of 2 and was discharged without event. on the day prior to discharge, the patient had a white blood cell count of 11.4, hematocrit was 30.4, and his platelets were 504. coagulations revealed prothrombin time was 17.3, partial thromboplastin time was 28.9, and his inr was 2. chemistries revealed sodium was 131, potassium was 5.3, chloride was 101, bicarbonate was 21, blood urea nitrogen was 46, creatinine was 1.4. the patient's calcium was 7.6, magnesium was 2.2, and phosphate was 3.1. medications on discharge: (the patient was discharged on medications of) 1. amiodarone 200 mg by mouth once per day. 2. levoxyl 75 mcg by mouth once per day. 3. albuterol nebulizer solution. 4. atrovent nebulizer solution. 5. aspirin 81 mg by mouth once per day. 6. colace 100 mg by mouth twice per day. 7. protonix 40 mg by mouth once per day. 8. levofloxacin 250 mg by mouth once per day. 9. lopressor 50 mg by mouth twice per day. 10. iron complex. 11. warfarin 2 mg by mouth once per day. 12. avandia 8 mg by mouth once per day. 13. nph insulin 15 units subcutaneously q.a.m. and 15 units subcutaneously q.p.m. discharge disposition: the patient was to be discharged to rehabilitation. condition at discharge: condition on discharge was good. discharge diagnoses: sternal wound instability/moderate infection; status post coronary artery bypass graft. , m.d. dictated by: medquist36 procedure: other incision of pleura injection or infusion of nesiritide diagnoses: coronary atherosclerosis of native coronary artery pure hypercholesterolemia other postoperative infection unspecified pleural effusion unspecified essential hypertension unspecified acquired hypothyroidism other specified complications of procedures not elsewhere classified diabetes mellitus without mention of complication, type i [juvenile type], not stated as uncontrolled 

Answer: The patient is high likely exposed to
