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 72 non-diabetic white male with a known 5.7 cm abdominal aortic aneurysm who was seen at the hospital on for back pain. a ct scan of the abdomen showed enlargement of the aaa to 6.3 cm. the patient also described an episode of shortness of breath and disorientation. a chest x-ray done at showed a left lower lobe pneumonia. the patient was started on salmeterol and levaquin. the patient was transferred to the emergency room for a preoperative evaluation. he was found to have atrial fibrillation with a rapid ventricular response. this was treated successfully with intravenous lopressor. the patient also received two units of fresh frozen plasma for supra-therapeutic inr. however, after undergoing preoperative cardiac evaluation, the patient refused operative repair of his aaa. the patient reconsidered and agrees to have an elective aaa resection. past medical history: 1. atrial fibrillation. 2. chronic obstructive pulmonary disease, o2 dependent. 3. prostate carcinoma with recurrence; treated with radiation therapy. 4. hypercholesterolemia. 5. diverticulosis. 6. history of epistaxis. past surgical history: 1. transurethral resection of the prostate. 2. incision and drainage of abdomen. 3. left inguinal hernia. family history: noncontributory. social history: the patient lives with his wife. ambulates independently. he quit smoking years ago. he does not drink alcohol. allergies: no known drug allergies. medications on admission: 1. coumadin 2 mg p.o. q. day; stopped preoperatively. 2. digoxin 0.125 mg p.o. q. day. 3. prednisone 10 mg p.o. q. day. 4. lopressor 25 mg p.o. three times a day. 5. cardizem cr 240 mg p.o. q. day. 6. lipitor 10 mg p.o. q. day. 7. nexium 40 mg p.o. q. day. 8. theophylline 200 mg p.o. twice a day. 9. albuterol inhaler one puff twice a day. 10. o2 at three liters via nasal cannula. physical examination: vital signs were pulse of 78; respiratory rate of 16; blood pressure 100/52. in general, alert, cooperative white male in no acute distress. heent: normocephalic. pupils equally round and reactive to light. tongue in midline. pharynx clear. neck with range of motion within normal limits; no lymphadenopathy of thyromegaly. chest: heart regular rate and rhythm without murmur. lungs: scattered rhonchi, no wheezing. abdomen soft, nontender, no bruits. large pulsatile mass, mid abdomen. rectal examination is deferred. extremities: feet equally warm; arthritic changes. pulse examination: carotids, radial, femoral, popliteal, dorsalis pedis pulses all two plus bilaterally. posterior tibial pulses one plus bilaterally. neurological examination is nonfocal. laboratory: admission labs on , white blood cell count 9.6, hemoglobin 11.7, hematocrit 37.6, platelets 344,000. pt 15.3, ptt 35.7, inr 1.5. sodium 141, potassium 3.9, chloride 97, co2 40, bun 17, creatinine 0.9; glucose 116. chest x-ray on , showed severe chronic obstructive pulmonary disease; left lower lobe infiltrate decreased since chest x-ray but with small residual focal density. ekg on , showed atrial fibrillation with rapid ventricular response and occasional ventricular ectopy. rate 121. a portable transthoracic echocardiogram done on , was sub-optimal. the left ventricle had a normal wall thickness, cavity size and systolic function ( left ventricular ejection fraction greater than 55% ). hospital course: the patient was admitted to the hospital on . a modified bowel prep was ordered. on , the patient underwent an uneventful aaa repair. the aneurysm was estimated to be 6.6 cm. he received two units of packed red blood cells and cc from the cellsaver. ekg showed atrial flutter but no ischemia. the patient remained intubated until postoperative day number five, but after a short period of extubation, had to be re-intubated because of respiratory failure. on postoperative day number one, the patient was hypovolemic. he received two units of packed red blood cells and two units of fresh frozen plasma. his cardiac enzymes were flat. he received another two units of packed red blood cells on . postoperative pain was managed initially with an epidural. the patient then was given intravenous morphine 1 to 5 mg q. four hours p.r.n. pain. at the time of discharge, the patient was free of incisional pain. the patient had an episode of rapid atrial fibrillation. this was treated with intravenous lopressor and intravenous diltiazem. cardiology was consulted and recommended resuming the patient's coumadin. the patient was started on 5 mg of coumadin and will be discharged on 2 mg coumadin p.o. q. day. inr on , was 2.3. because of the patient's prolonged intubation, he was started on tpn. he began to have bowel sounds and passed flatus about postoperative day number seven. he was able to tolerate tea and toast. his diet was advanced as tolerated. physical therapy worked with the patient and recommended short term rehabilitation stay. the patient's theophylline was stopped because it was thought by cardiology that it was contributing to his tachycardia. the patient's respiratory function was at baseline with prednisone 10 mg p.o. q. day, inhalers and o2 via nasal cannula at three liters. at time of dictation, the patient's abdominal and groin incisions are clean, dry and intact. the patient will be discharged to short term rehabilitation facility. he will follow-up with dr. after discharge from rehabilitation. discharge medications: 1. coumadin 2 mg p.o. q. day. 2. digoxin 0.625 mg p.o. q. day. 3. lopressor 50 mg p.o. three times a day. 4. diltiazem 30 mg p.o. four times a day. 5. atorvastatin 20 mg p.o. q. day. 6. prednisone 10 mg p.o. q. day. 7. ipratropium bromide, six puffs four times a day. 8. fluticasone 110 micrograms, four puffs twice a day. 9. albuterol nebulizer inhalation q. six hours p.r.n. 10. albuterol, one to two puffs inhalation twice a day. 11. heparin 5000 units subcutaneously q. 12 hours. 12. aspirin 325 mg p.o. q. day. 13. pantoprazole 40 mg p.o. q. day. 14. haldol 5 mg p.o. three times a day. condition at discharge: satisfactory. disposition: short term rehabilitation. primary diagnosis: 1. enlarging abdominal aortic aneurysm. 2. abdominal aortic aneurysm resection with aorta-bifemoral bypass graft on . secondary diagnoses: 1. blood loss anemia, status post transfusion. 2. respiratory failure, requiring reintubation. 3. postoperative malnutrition requiring total parenteral nutrition. 4. hypovolemia, requiring transfusion and fluid resuscitation. 5. atrial flutter. 6. severe chronic obstructive pulmonary disease, steroid and o2 dependent. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours parenteral infusion of concentrated nutritional substances insertion of endotracheal tube aorta-iliac-femoral bypass arterial catheterization resection of vessel with replacement, aorta, abdominal diagnoses: pure hypercholesterolemia acute posthemorrhagic anemia chronic airway obstruction, not elsewhere classified atrial fibrillation atrial flutter acute respiratory failure abdominal aneurysm without mention of rupture diverticulosis of colon (without mention of hemorrhage) 

Answer: The patient is high likely exposed to
