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: patient recorded as having no known allergies to drugs attending: chief complaint: sob/doe major surgical or invasive procedure: coronary artery bypass grafting x4 with a left internal mammary artery graft to the left anterior descending and reverse saphenous vein graft to the right coronary artery, marginal branch, and first diagonal branch of the left anterior descending history of present illness: ms. is an 82-year-old female with worsening symptoms of dyspnea on exertion and chest tightness who underwent cardiac catheterization that showed left main and three-vessel disease. she is presenting for revascularization. past medical history: arthritis hypertension gout gastroesphageal reflux disease chronic renal insufficiency (creatinine 1.6) degenerative joint disease diverticulosis anemia venous insufficiency social history: patient denies smoking, occasional etoh physical exam: neuro: grossly intact, awake and alert lungs: clear to auscultation bilaterally -w/r/r heart: rrr -c/r/m/g abd: soft, nt/nd +bs -r/r/g ext: warm, no edema pertinent results: 06:20am blood wbc-14.0* hct-28.8* 09:20am blood wbc-13.1* rbc-3.19* hgb-9.7* hct-30.9* mcv-97 mch-30.5 mchc-31.6 rdw-15.4 plt ct-487* 06:20am blood urean-37* creat-1.6* k-3.9 09:20am blood urean-35* creat-1.6* k-3.8 08:40am urine color-straw appear-clear sp -1.011 08:40am urine blood-neg nitrite-neg protein-neg glucose-neg ketone-neg bilirub-neg urobiln-neg ph-5.0 leuks-neg brief hospital course: the patient was admitted to the hospital and taken to the operating room the following day. the patient underwent a coronary artery bypass graft x 4. she tolerated this procedure well. for full operative details, please see operative note. the patient was transferred to the csru immediately after surgery in stable condition. later on op day, pt was weaned from mechanical ventilation and sedation and extubated. on post-op day #1, the patient's chest tube and central lines were removed. on post-op day #2, her diuresis and b-blockers were continued, she was weaned off supplemental oxygen and was transferred to the floor in stable condition. on post-op day #3, pt appeared to be slowly improveing, epicaridal pacing wires were removed, and the patient was encouraged to get oob and ambulate. pt. was recovering well and awaiting rehab placement from pod #. during this time though, her wbc started to trend upwards (w/out increase in temp) and on pod #9 serosang. drainage was noticed coming from her sternal incision. appropriate cultures were taken and pt was placed on antibiotics. picc line was placed on pod #10 and antibiotics (vanco/levo) were cont. for the rest of her hopsital course. b-blocker was adjusted for maximal bp control and diuretics titrated until pt was at pre-op wt. from pod # pt's wbc was trending down and pt appeared she would be transferred to rehab facility. on pod #13 though, her wbc was once again elevated, a cxr and ua were negative and her midsternal incision was clean and dry. subsequently her wbc fell to 13, and she was ready for discharge. medications on admission: 1. celebrex 200mg po qdaily 2. maxide 3. toprol xl 50mg po bid 4. norvasc 20.mg po qdaily 5. lisinopril 40mg po qdaily discharge medications: 1. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). disp:*30 tablet, delayed release (e.c.)(s)* refills:*2* 2. oxycodone-acetaminophen 5-325 mg tablet sig: one (1) tablet po q4-6h (every 4 to 6 hours) as needed for pain for 30 doses. disp:*30 tablet(s)* refills:*0* 3. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). 4. pantoprazole 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q24h (every 24 hours). 5. metoprolol tartrate 50 mg tablet sig: 1.5 tablets po bid (2 times a day). 6. vancomycin in dextrose 1 g/200 ml piggyback sig: one (1) intravenous q48h (every 48 hours) for 7 days. 7. levofloxacin 250 mg tablet sig: one (1) tablet po q48h (every 48 hours) for 7 days. 8. furosemide 40 mg tablet sig: one (1) tablet po daily (daily). 9. miconazole nitrate 2 % powder sig: one (1) appl topical qid (4 times a day) as needed. discharge disposition: extended care facility: nursing home -
