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. history of hypertension. 2. history of pneumonia. social history: he lives at home with his wife. does not smoke. he does not drink alcohol. allergies: the patient has no known drug allergies. admission medications: he did not taken any medications at home but on transfer was taking lopressor 25 mg p.o. b.i.d. and aspirin 325 mg. review of systems: unremarkable. physical examination on admission: general: the patient was a well-developed, well-nourished asian male in no apparent distress. the vital signs were stable. heent: perrl, eomi, oropharynx benign with good dentition. his neck was supple with a full range of motion. he had no lymphadenopathy or thyromegaly. his carotids were 2+ and equal bilaterally without bruits. his lungs were clear to auscultation bilaterally. his heart revealed a regular rate and rhythm without rub or gallop. there is a iii/vi holosystolic ejection murmur from the apex to the axilla. abdomen: positive bowel sounds, soft, nontender, without masses or hepatosplenomegaly. extremities: without clubbing, cyanosis or edema. he had 2+ pulses bilaterally throughout. neurologic: nonfocal. laboratory/radiologic data: on admission, white count 6.2, hematocrit 41.3%, platelet count 539,000. potassium 3.8, bun 16, creatinine 1.2. the ekg showed sinus rhythm in the 60s with st elevations in the inferior leads, st elevations in v2, v3, and v6. hospital course: while awaiting surgery, he was seen by the electrophysiology staff in regards to his syncopal episode. they did feel that his syncopal episode was consistent with a possible vagal episode but they felt that they would rather do ep studies following his cabg and at that point may or may not place an aicd. on , he underwent coronary artery bypass grafting times three with left internal mammary artery to left anterior descending artery, saphenous vein graft to the om, and saphenous vein graft to the pda. he also had a mitral valve replacement with a #31 carbomedics mechanical valve and intra-aortic balloon pump placed intraoperatively. this surgery was performed by dr. with , nurse practitioner as the assistant. the surgery was performed under general endotracheal anesthesia with the cardiopulmonary bypass time of 175 minutes and a cross-clamp time of 154 minutes. the patient was transferred to the cardiac surgery recovery unit on epinephrine, milrinone, nitroglycerin, and propofol in normal sinus rhythm, two atrial and two ventricular pacing wires and two mediastinal and one left pleural chest tube. in the immediate postoperative period the patient was noted to have a nosebleed and increased chest tube drainage. he was given protamine, 1 unit of ffp, 4 units of packed cells, and one dose of cryoprecipitate. he was noted to have profound hypotension and underwent tee which revealed hypokinetic anterior wall but was actually better than the immediate postoperative tee. on postoperative day number one, he remained sedated and intubated. he continued on the milrinone drip and the epinephrine drip was weaned to 0.01 micrograms. his epinephrine drip was eventually weaned and discontinued during that day. by postoperative day number two, his milrinone was decreased and he was started on lasix for diuresis. also on postoperative day number two, his sedation was lightened. he was able to move everything to commands but became hypotensive and was eventually placed back on the propofol drip. by postoperative day number three, he was continued to be hemodynamically stable after epinephrine with the milrinone weaned down slightly. his intra-aortic balloon pump was discontinued without incident. he continued to be sedated and the ventilator was weaned. also, on this day he was noted to be in atrial flutter and an amiodarone bolus was given. he was almost cardioverted but converted to normal sinus rhythm on his own. also, his propofol was weaned to off on this day. off the propofol, he was very slow to wake and remained lethargic the following postoperative day but did follow commands and move all extremities. by postoperative day number four, the ventilator continued to be very slowly weaned and his milrinone was decreased to 0.25. later that day, he had paroxysmal atrial fibrillation from which he converted to normal sinus rhythm and then a junctional rhythm. he continued on amiodarone and had started on heparin. on postoperative day number five, he had his chest tube discontinued and he had a new left subclavian cordis and swan placed. his chest x-ray did show a left-sided pneumothorax and he did have a new chest tube inserted on that side which showed reinflation of the left lung. by postoperative day number six, his milrinone was discontinued and he continued to have good cardiac function. he was also extubated on postoperative day number six and tolerated that well. by postoperative day number seven, he was started on heparin for anticoagulation for his atrial fibrillation and his mechanical mitral valve. he was also transferred to the surgical floor on this day and began more aggressive physical therapy. by postoperative day number eight, it was decided that his coumadin should be held in case the plan for ep study and insertion of a icd would be done this admission. he continued to be treated with heparin and have his coumadin held while the electrophysiology service sorted out his echocardiogram and decided when would be the best time to do his studies. he did have a rise in his white blood cell count on postoperative day number nine and cultures were sent. his chest x-ray did show a left lower lobe consolidation and he was started on levofloxacin. on postoperative day number 11, he was complaining of throat pain. he was noted to have a purulent exudate around his uvula and he was started on rocephin for that and his levaquin was discontinued. his coumadin continued to be held because his inr had bumped high and were waiting for it to decreased to remove his pacing wires. during that time, it was felt that he would not need to have ep studies during this admission and the plan was for him to return after discharge to see dr. for further electrophysiology workup. by postoperative day number 12, his inr had drifted down to 1.9 and his pacing wires were discontinued without incident. he was restarted on his coumadin and was awaiting elevation of his inr to be discharged home. over the next week, he did receive doses of anywhere from 1-3 mg of coumadin each time his inr would bump into the range of 5. the remainder of his hospital course was uncomplicated. by the second attempt at anticoagulation, his inr drifted down to 2.6 and he was started on 1 mg of coumadin and was discharged on this dose. discharge
