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 76 year old woman with a past medical history significant for diabetes mellitus, asthma and hypertension who presented to an outside hospital with six hours of chest pain that woke her up at night, occurred at rest and continued. at the outside hospital, the patient was found to be in rapid atrial fibrillation. she was treated with 25 mg of intravenous diltiazem. she converted to normal sinus rhythm. cardiac enzymes were negative. she was transferred to for further workup. past medical history: hypertension. diabetes mellitus. obesity. hypercholesterolemia. lyme disease. pulmonary nodules. allergies: she is allergic to ace inhibitors which give her a cough and she is allergic to codeine which causes shortness of breath. medications: preoperative medications include: 1. adalat 60 mg p.o. q day. 2. diovan 80 mg p.o. twice a day. 3. aspirin 81 mg p.o. q.o.d. 4. flovent 110 micrograms, two puffs twice a day. 5. nph insulin 14 units subcutaneously q a.m. and 20 units subcutaneously q p.m. hospital course: the patient was taken for a cardiac catheterization on which showed three vessel coronary artery disease. the patient was seen by dr. in consultation and the decision was made to take the patient to the operating room for a coronary artery bypass grafting. the patient was taken to the operating room on with dr. for a coronary artery bypass graft times four, left internal mammary artery to left anterior descending; saphenous vein graft to the distal right coronary artery; saphenous vein graft to obtuse marginal and saphenous vein graft to ramus as well as a rf maze procedure which included a radiofrequency ablation of the pulmonary vein. please see operative note for full details. the patient tolerated the procedure well and she was transferred to the intensive care unit in stable condition. the patient was weaned and extubated from mechanical ventilation on the evening of postoperative day zero, required moderate amount of aggressive pulmonary toilet initially. on postoperative day number one, the patient was started on beta blockers and remained hemodynamically stable. the patient was noted to have an elevated white blood cell count of 20 postoperatively. this subsequently decreased to 11 the day prior to discharge. the patient was transferred from the intensive care unit to the regular part of the hospital on postoperative day number two. in the evening of postoperative day number two, the patient was noted to be in rapid atrial fibrillation. the patient received intravenous lopressor and amiodarone and subsequently converted into sinus rhythm. the patient remained in sinus rhythm for the remainder of her hospital stay. the patient began working with physical therapy. it was decided that the patient would benefit from a stay at a short term rehabilitation facility. the decision was made by dr. not to place the patient on any anti-coagulation for the atrial fibrillation as she had been in continued sinus rhythm since her one postoperative event. the patient's chest tubes were removed without incident. the patient was tolerating her lopressor and by postoperative day number four, she was cleared for discharge to a rehabilitation facility by postoperative day number five. condition on discharge: temperature max 98.7 f.; pulse 56 in sinus rhythm; blood pressure 119/50; room air oxygen saturation 95 percent. neurologically, the patient is awake, alert, and oriented times three with a nonfocal neurological examination. heart is regular rate and rhythm without rub or murmur. respiratory: breath sounds are decreased at bilateral bases. gastrointestinal: positive bowel sounds, soft, nontender, nondistended, tolerating a regular diet. the extremities are warm and well perfused with one to two plus pitting edema of bilateral lower extremities. right lower extremity vein harvest site is clean, dry and intact. sternal incision with staples are intact. the incision is clean and dry. the sternum is stable. laboratory data: white blood cell count 11.0, hematocrit 29.1, platelet count 251. sodium 142, potassium 4.5, chloride 106, bicarbonate 28, bun 17, creatinine 0.6 and glucose 135. discharge medications: 1. lopressor 50 mg p.o. twice a day. 2. lasix 20 mg p.o. twice a day times ten days. 3. potassium chloride 20 meq p.o. twice a day times ten days. 4. colace 100 mg p.o. twice a day. 5. zantac 150 mg p.o. twice a day. 6. enteric coated aspirin 325 mg p.o. twice a day. 7. plavix 75 mg p.o. q day. 8. valsartan 80 mg p.o. twice a day. 9. flovent mdi, 110 micrograms, two puffs p.o. twice a day. 10. dilaudid 2 to 4 mg p.o. q four to six hours p.r.n. 11. amiodarone 400 mg p.o. q day times one month. 12. nph insulin 14 units subcutaneously q a.m. and 14 units subcutaneously q p.m. 13. regular insulin sliding scale. discharge instructions: 1. the patient is to be discharged to rehabilitation in stable condition. 2. the patient is to followup with her cardiologist, dr. , in one to two weeks. 3. the patient is to followup with her primary care physician, . , in one to two weeks. 4. the patient is to followup with dr. in three to four weeks. 5. the patient's staples in her sternal incision should be discontinued three weeks after the date of surgery, which is on or about approximately . discharge diagnoses: 1. coronary artery disease. 1. paroxysmal atrial fibrillation. 1. hypertension. 1. diabetes mellitus. , procedure: (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery angiocardiography of left heart structures left heart cardiac catheterization coronary arteriography using a single catheter diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome pure hypercholesterolemia unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled atrial fibrillation asthma, unspecified type, unspecified 

Answer: The patient is high likely exposed to
