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: 1. status post coronary artery bypass graft in . 2. status post re-do coronary artery bypass graft in . 3. hypercholesterolemia. 4. hypoglycemia. 5. status post ear surgery. allergies: no known drug allergies. preoperative medications: 1. isordil 120 mg po q day. 2. prevacid 15 mg po q day. 3. atenolol 50 mg po q day. 4. altace 10 mg po q day. 5. aspirin 325 mg po q day. 6. lipitor 20 mg po q day. physical examination: vital signs, pulse 74 regular rate and rhythm. blood pressure 128/68. respiratory rate 22. room air oxygen saturation 98%. weight 170 pounds. this is a well appearing 65 year-old male in no acute distress. skin without lesions or rashes. heent is unremarkable. neck is supple. chest lungs are clear to auscultation bilaterally. heart s1 and s2 regular rate and rhythm. abdomen is soft, nontender, nondistended. extremities are warm and well profuse with trace pedal edema. laboratory data: white blood cell count 7.7, hematocrit 42.6, platelet count 159, sodium 143, potassium 4.5, chloride 106, bicarb 27, bun 13, creatinine 1.1. electrocardiogram showed normal sinus rhythm with borderline izcd. ho course: the patient was taken to the operating room by dr. on for a coronary artery bypass graft times three, radial artery to obtuse marginal, saphenous vein graft to diagonal and saphenous vein graft to posterior descending coronary artery. the patient was transferred to the intensive care unit in stable condition. the patient was weaned from mechanical ventilation and extubated on postoperative day number one. the patient required neosinephrine and fusion to maintain adequate blood pressure. the patient was also maintained on a nitroglycerin drip for the radial artery graft. neosinephrine was weaned to off by postoperative day number three. the patient was able to maintain adequate blood pressure. the patient remained in the intensive care unit requiring aggressive pulmonary toilet for what was thought to be an upper respiratory infection or bronchitis. sputum cultures from showed only oropharyngeal flora. chest x-ray showed right lower lobe atelectasis and small left effusion. no identifiable infiltrate. the patient was started on levaquin for presumed bronchitis. the patient had reported being on antibiotics for bronchitis prior to entering the hospital. the patient was requiring around the clock nebulizer treatments with albuterol and atrovent as well as humidified o2 and aggressive chest physical therapy. the patient's coughing and sputum production gradually subsided as o2 requirement decreased and the patient was transferred out of the intensive care unit on postoperative day number four. the patient continued to require aggressive pulmonary toilet with around the clock nebulizer treatments. the patient remained afebrile during this time. the patient's white blood cell count rose to high of 14.7 on postoperative number two, but quickly returned to by postoperative number four. by postoperative number seven the patient was weaned from nasal cannula. the patient was ambulating 500 feet and climbing stairs with physical therapy on room air tolerating activity well. on postoperative day number eight the patient was cleared for discharge. condition on discharge: temperature max 98.2. pulse 80 sinus rhythm with frequent premature atrial contractions. blood pressure 116/60. respiratory rate 20. room air oxygen saturation 98%. weight 78.4 kilograms. neurological intact. cardiovascular regular rate and rhythm without rub or murmur. respiratory breath sounds clear bilaterally, moderately productive cough for yellow sputum. gastrointestinal, positive bowel sounds, soft, nontender, nondistended, tolerating a regular diet although with decreased appetite. sternal incision is clean and dry without drainage or erythema. sternum is stable. left radial artery graft harvest site is clean and dry with minimal erythema. no drainage. saphenectomy sites are clean and dry without erythema. electrocardiogram on showed sinus arrhythmia with a right bundle branch block. chest x-ray from showed small bilateral effusions with right lower lobe atelectasis. laboratory on discharge: white blood cell count 10.6, hematocrit 31.5, platelet count 244, sodium 136, potassium 4.8, chloride 99, bicarb 29, bun 26, creatinine 0.9. the patient is to be discharged to home in stable condition. discharge diagnoses: 1. status post coronary artery bypass graft second re-do. 2. status post coronary artery bypass graft . 3. status post coronary artery bypass graft . 4. hypercholesterolemia. 5. hyperglycemia. 6. status post ear surgery. discharge medications: 1. lopressor 25 mg po b.i.d. 2. lasix 20 mg po q day times seven days. 3. k-ciel 20 milliequivalents po q day times seven days. 4. guaifenesin 400 mg po q.i.d. times seven days. 5. levaquin 500 mg po q day times six days. 6. aspirin 81 mg po q day. 7. lipitor 20 mg po q.h.s. 7. percocet 5/325 one to two tabs po q 4 to 6 hours prn. 8. ibuprofen 400 mg po q 4 to 6 hours prn. 9. combivent mdi with spacer two puffs q.i.d. times one week and then prn. 10. imdur 30 mg po q day times three months. , m.d. dictated by: medquist36 procedure: (aorto)coronary bypass of three coronary arteries diagnoses: pure hypercholesterolemia coronary atherosclerosis of autologous vein bypass
