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: the patient is a 65 year old male with a history of hypertension, positive for shortness of breath with diaphoresis and chest pain. the chest pain decreased with sublingual nitrogen but the pain recurred after the patient was transferred to the intensive care unit. the patient was noted to have decreased st segments on electrocardiogram. the electrocardiogram was increased at 1900 and his troponin n was greater than 80. the patient received 2 units of packed red blood cells to help treat the shortness of breath. the patient also during the first hospital day stay in the intensive care unit had increased agitation which was treated with haldol. the patient had a catheterization done at an outside hospital showing an ejection fraction of 37%, a right coronary artery between 70 and 80% and left axis 90% left anterior descending at 60 to 70%. the patient was then referred for coronary artery bypass graft at . past medical history: initially, systemic lupus erythematosus, hypertension medications: zestril, norvasc, plaquenil, lipitor, aspirin, intravenous nitroglycerin, ativan social history: 100 pack per year tobacco history and positive ethyl alcohol for six to seven beers per day. allergies: no known drug allergies. physical examination: initial physical examination showed temperature maximum 102, pulse 78, blood pressure 102/46, respiratory was coarse breathsounds. cardiovascular was regular rate and rhythm. s1 and s2 with no murmurs. abdomen was nontender, positive bowel sounds and peripheral showed no edema. no varicosities shown. laboratory data: initial laboratory data showed white blood cell count 4.6, hematocrit 28, platelets 172, sodium 132, potassium 4.8, chloride 102, carbon dioxide 20, bun 21, creatinine 1.3, and glucose of 104. ck was 90 to 1100 to 1900, mb was maximum of 290, troponin was maximum greater than 50. pt was 11.9 with an inr of .97, ptt 74. electrocardiogram showed st depressions in v2 through v4 and no q waves. hospital course: the patient was admitted on , to the internal medicine coronary care service. the patient was noted to be a fairly large alcohol drinker and was started on ativan and serax for delirium tremens prophylaxis. the patient was monitored for coronary artery disease, scheduled for a coronary artery bypass graft. on the patient was transferred to cardiothoracic surgery for coronary artery bypass graft. the patient was transported to the operating room with initial diagnosis of three vessel coronary artery disease, unstable angina, hypertension and systemic lupus erythematosus. the patient had a coronary artery bypass graft times four with left internal mammary artery to left anterior descending, saphenous vein graft to the right coronary artery, obtuse marginal 1, and obtuse marginal 2. the patient tolerated the procedure well and was transported to the cardiothoracic intensive care unit. the patient did well postoperative day #1 and was transferred to the floor. on postoperative day #1 the patient was also continued on his delirium tremens prophylaxis. on postoperative day #2 the patient continued to do well and increased his ambulation. on postoperative day #2, the patient's nurse complained of mild agitation and symptoms of delirium. the patient had a sitter for the night and on postoperative day #3 the sitter mentioned that the patient slept almost 90% of the night and wound up getting out of bed only once to go to the bathroom. hence, the sitter was discontinued. on postoperative day #3 the patient also continued to cough up sputum and was sent for a chest x-ray and a sputum culture. on postoperative day #4 the gram stain came back as +1 gram positive cocci in pairs and in chains. the culture came back as positive for oropharyngeal flora, yet still pending. the patient was started on levaquin 500 mg p.o. q.d. times ten days and will be reassessed after the final cultures are back. the patient was also assessed on postoperative day #4 for rehabilitation and will be transferred to a rehabilitation center on . discharge physical: temperature 99.2, pulse 96, respiratory rate 20, blood pressure 114/72, respiratory rate 20, saturated oxygen 96% on 4 liters +1 kg. cardiovascular: regular rate and rhythm. respiratory is clear to auscultation bilaterally. abdomen was soft, nontender, nondistended. extremities: mild swelling. incision is clean, dry and intact, both chest and lower extremities. complications: gram positive sputum for which the patient was started on levaquin. discharge medications: 1. serax 50 mg p.o. q. 8 prn 2. plaquenil 20 mg p.o. t.i.d. 3. levaquin 500 mg p.o. q.d. times ten days 4. lopressor 100 mg p.o. b.i.d., hold for systolic blood pressure less than 100, heartrate less than 60 5. lasix 40 mg q.d. 6. calcium chloride 20 mg b.i.d. 7. docusate 100 mg p.o. b.i.d. 8. aspirin 81 mg p.o. q.d. 9. ibuprofen 400 mg prn p.o. q. 4 to 6

patient will follow up with dr. office in three to four weeks. primary discharge diagnosis: 1. coronary artery bypass graft times four secondary diagnosis: 1. systemic lupus erythematosus 2. hypertension , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for 96 consecutive hours or more (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass enteral infusion of concentrated nutritional substances cardioplegia diagnoses: systemic lupus erythematosus anemia, unspecified unspecified essential hypertension acute myocardial infarction of anterolateral wall, initial episode of care pneumonitis due to inhalation of food or vomitus unspecified disorder of kidney and ureter other and unspecified alcohol
