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 68 year old gentleman who is status post coronary artery bypass graft times three in with a five year history of exertional chest and throat discomfort. the patient underwent cardiac catheterization in which revealed patent bypass graft. the patient underwent a follow up stress test in which showed ischemic st changes. the patient had a cardiac catheterization in which showed occluded vein grafts of the right coronary artery with native three vessel coronary artery disease and an ejection fraction of 33%. the patient was referred to dr. for operative treatment. past medical history: 1. status post coronary artery bypass graft times three in ; 2. hypercholesterolemia; 3. noninsulin dependent diabetes mellitus; 4. arthritis; 5.

patient was admitted to on and was taken to the operating room with dr. for a redo sternotomy and redo coronary artery bypass graft times three, left internal mammary artery to left anterior descending, saphenous vein graft to obtuse marginal and saphenous vein graft to posterior descending artery. the patient tolerated the procedure well and was transferred to the intensive care unit in stable condition. please see the operative note for further details. the patient initially required levophed drip for maintenance of the blood pressure. in the intensive care unit the patient had several short runs of nonsustained ventricular tachycardia for which he was started on amiodarone infusion. she was weaned and extubated from mechanical ventilation on the first postoperative evening and postoperative day #1 the patient was transferred from the intensive care unit to the floor. on the evening of postoperative day #1 into postoperative day #2 the patient became progressively hypoxic without improvement with diuretics, pain control or nebulizer treatment. the morning of postoperative day #2 the patient was transferred from the floor back to the intensive care unit for hypoxia. prior to transfer the patient was found to be hypotensive and significantly hypoxic and was electively intubated prior to transfer. intubation was without complications. upon arrival to the intensive care unit the patient underwent a bronchoscopy which showed normal mucosa, copious thin secretions and a small plug in the left lower lobe. a sputum sample was sent from the bronchoscopy. chest x-ray after intubation showed diffuse interspace disease, right greater than left. the patient was empirically started on antibiotics, levofloxacin, vancomycin and flagyl. the patient remained significantly hypoxic, requiring paralytics and sedation and pressure control ventilation. the patient underwent a transesophageal echocardiogram which showed severely depressed left ventricular systolic function with ejection fraction of 20 to 25% with inferior akinesis, lateral hypokinesis, moderately depressed right ventricular systolic function, moderate mitral regurgitation and mild tricuspid regurgitation. paralytics were discontinued on postoperative day #3. on postoperative day #4 pulmonary medicine consult was obtained due to the patient's continued respiratory failure, fevers of unknown origin and diffuse patchy infiltrates on chest x-ray, the pulmonary medicine team's feelings were that the respiratory failure was either due to aspiration pneumonia or amiodarone toxicity or atypical pneumonia. the pulmonary team recommended again using steroids, recommended discontinuing amiodarone. considering the present management, the patient was pancultured for his continued fever spikes of 102. all of the cultures from that time were negative with the exception of a sputum sample done during bronchoscopy which was positive for methicillin-sensitive coagulase positive staphylococcus which was minimal growth. all subsequent sputum, blood and urine cultures were negative. on postoperative day #4 the patient had a pulmonary artery catheter placed to rule out cardiogenic pulmonary edema that showed a cardiac output of 7.2 and a cardiac index of 3.17, svr of 715. the pulmonary artery catheter was removed as it was felt that the patient had adequate cardiac output. on postoperative day #4, the patient was switched from pressure control ventilation to conventional ventilation with assist control and subsequent to simv. the patient's sedation was slowly weaned down. the patient continued to have improving oxygenation over the next several days. the patient's positive end-expiratory pressure and sedation were weaned. the patient's fever curve continued to defervesce. the patient had no further atrial or ventricular ectopy. it was thought that the patient did not require any anti-arrhythmic therapy. on postoperative day #6 the patient again spiked a fever to 102.9. blood cultures were sent which were negative. the patient's central line was removed. the patient continued on triple antibiotic therapy. the patient's white count during this time remained steady in the 13 to 15 range. by postoperative day #8 the patient continued to have fevers. the patient was weaning on the ventilator and had been weaned down to cpap with pressure support, required diamox for metabolic alkalosis. sedation had been weaned off, however, the patient was agitated and not following commands, restless in the bed. a neurological consult was obtained which neurology felt that the majority of his problem was probably due to metabolic and infectious causes, however, felt that it could be due to a stroke and recommended an magnetic resonance imaging scan at a future date to further delineate this. however, by postoperative day #9, the patient's mental status had improved. the patient began to follow commands and move all extremities to command, and their recommendations were changed to consider the magnetic resonance imaging scan if the patient did not continue to progress. the patient continued to progress from a neurologic standpoint. by postoperative day #9, the patient was weaned and extubated from mechanical ventilation and continued to improve from a pulmonary standpoint, was able to tolerate nasal cannula by the morning of postoperative day #10 and required some pulmonary toilet, encouragement with coughing and deep breathing. it was noted about this time that the patient had an area of skin abrasion on his lower coccyx and gluteal cleft. duoderm was applied and subsequent skin care specialist evaluated the patient and felt that it was a stage 2 ulcer and recommended continuing duoderm. the patient continued to improve, neurologically. he was quickly weaned off of oxygen to room air by postoperative day #11. fever curve decreased by postoperative day #11, temperature maximum was 98. the patient continued to have episodes of confusion and delirium, however, he was following commands and moving all extremities equally. the patient's delirium continued to improve. the patient's antibiotics were weaned. the vancomycin and the flagyl were discontinued as the patient had no positive culture, was continued on the levofloxacin. the patient was tolerating a regular diet without signs or symptoms of aspiration. the patient began walking with physical therapy, ambulating in the intensive care unit. by postoperative day #13, the patient was transferred from the intensive care unit to the regular floor. he remained hemodynamically stable and was able to ambulate with assistance, on room air and by postoperative day #15 the patient was deemed stable for discharge to a rehabilitation facility. the patient will be discharged on postoperative day #16. condition on discharge: temperature maximum 96.5, pulse 78 in sinus rhythm, blood pressure 95/60, respiratory rate 18, room air oxygen saturation 95%, patient's weight on was 90.1 kg. preoperatively the patient weighed 100 kg. the patient was awake, alert and oriented times three, moving all extremities equally. heart regular rate and rhythm without rub or murmur. respiratory breath sounds are clear bilaterally. abdomen, positive bowel sounds, soft, nontender, nondistended, tolerating regular diet. extremities were warm and well perfused, no edema. the pressure ulcer over the gluteal cleft is covered with duoderm. there is some mild erythema. there is no fluctuance. the sternal incision is clean and dry. the sternum is stable. staples are intact. left leg, vein harvest incision is clean and dry. steri-strips are intact. laboratory data: laboratory data revealed white blood cell count 13.1, sodium 136, potassium 5.0, chloride 98, bicarbonate 29, bun 27, creatinine 1.1, glucose 104. the patient has a chest x-ray pending for . discharge medications: 1. lopressor 25 mg p.o. b.i.d. 2. colace 100 mg p.o. b.i.d. 3.
