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 an 81 year old woman with a history of atrial fibrillation, coronary artery disease status post angioplasty, status post total abdominal hysterectomy, who presents with a several week history of chest pain worsening in frequency and duration over the last several days. the patient describes this pain as drowning and suffocating with shortness of breath lasting five to 30 minutes. the symptoms typically like her old angina. no radiation, no nausea or vomiting; non-pleuritic chest pain. prior to current episode, last angina was many years ago. no tearing or ripping sensation. no diaphoresis, no orthopnea or paroxysmal nocturnal dyspnea. the patient presented to on , and had pain which was relieved with sublingual nitroglycerin. the patient was started on a heparin drip and nitropaste in the intensive care unit. an ekg showed no acute st or t changes, with atrial fibrillation at 80. past medical history: 1. atrial fibrillation. 2. angioplasty. 3. hernia repair. 4. total abdominal hysterectomy, oophorectomy 35 years ago. allergies: codeine, which causes nausea. social history: no tobacco, no alcohol. lives with her husband. family history: mother died at 66 with an myocardial infarction. brother, at 77, had a bypass graft. medications: 1. aspirin 81 mg p.o. q. day. 2. lopressor 25 mg p.o. q. day. 3. norvasc 5 mg p.o. q. day. 4. nitropatch 0.04 mg times 12 hours. 5. coumadin 2 mg times five days and 4 mg times two days. physical examination: temperature 97.6 f.; 130/82; pulse is 92; respiratory rate 18; 91% on room air and 93% on two liters. the patient is in no acute distress. crackles bilaterally at the bases; scattered wheezes. cardiac: irregularly irregular rate; no murmurs. no carotid bruit. belly is soft, nontender, guaiac negative. lower extremities with mild edema bilaterally and two plus dorsalis pedis and posterior tibial pulses. laboratory: ekg showed atrial fibrillation at 66; no acute st or t changes. chest x-ray showed cardiomegaly without evidence of failure. white blood cell count of 5.5, hematocrit of 38.2, platelets 222. chem-7 142, 4.1, 103, 30, 14, 0.8 and 95. hospital course: the patient was admitted to the service and was continued on a heparin drip, lopressor, aspirin and norvasc. the patient was kept on heparin and cardiac catheterization was performed when the patient's inr was less than 2.0. cardiac catheterization was performed on , which showed three-vessel disease. at that time, it was decided that the patient should undergo minimally invasive non-bypass coronary artery bypass graft. on , the patient underwent coronary artery bypass graft times three vessels with left internal mammary artery to the left anterior descending, saphenous vein graft to the diagonal and then sequentially to obtuse marginal 1. on postoperative day number one, the patient did well and had her swan-ganz catheter removed. the patient was transferred to the floor on postoperative day number one. on postoperative day number two, it was noted that the patient had right arm weakness and confusion. a neurology consultation was called and a stroke was diagnosed which was most likely related to the patient's atrial fibrillation. the patient was transferred back to the unit on postoperative day number two after this event. ct scan which was obtained after this embolic event showed a left thalamic hypodensity likely representing a subacute chronic infarction. on postoperative day number three, the patient's chest tubes were removed and the patient was sent for a swallow evaluation. the swallow study was clinically suspicious for aspiration, so the patient was made strictly npo. the patient also underwent a carotid artery study which showed significant plaque through the left internal carotid artery with no focal stenosis and severe narrowing throughout the left ica. the right ica suggests 80 to 99% stenosis. on , a vascular surgery consultation was called and their recommendation was for an mra. on , the patient was started on tube feeds with fiber at 10 cc an hour towards a goal of 55 cc an hour. on postoperative day number six, it was noted that the patient's neurologic examinations were improving. on postoperative day number seven, the patient underwent an mra of her carotids which demonstrated a left ica with total occlusion and a right ica with 80 to 99% stenosis. vascular surgery made the recommendation for intervention at six weeks postoperatively. the patient underwent a video swallow on , which she failed and she was to remain npo with tube feeds through her ng tube. on , a family discussion was initiated regarding plans for a peg, however, the family wished to wait to see whether or not her swallowing would improve before placing a peg. for this reason, the patient was started back on her coumadin on . on , a dobbhoff tube was placed for the comfort of the patient instead of an ng tube for tube feeds. on postoperative day number ten, rehabilitation screens were called as it was felt that the patient was stable for rehabilitation. discharge instructions: 1. the patient was to return for follow-up with swallow studies in a week to ten days after discharge. at that time, evaluation would be made as to whether or not she could resume p.o. diet. 2. the patient was to follow-up with dr. in vascular surgery in four weeks with regard to carotid artery surgery. 3. the patient was to follow-up with dr. in four weeks for a postoperative visit. disposition: the patient was discharged to rehabilitation on , on the following medications. discharge medications: 1. colace 100 mg per ng tube twice a day. 2. aspirin 81 mg per ng tube q. day. 3. dulcolax one p.r. p.r.n. 4. plavix 75 mg per ng tube q. day. 5. heparin drip 700 units an hour until therapeutic on coumadin with an inr of 2.0 to 2.5. 6. albuterol, atrovent nebulizers q. four hours p.r.n. 7. tylenol 650 mg p.o. q. four hours p.r.n. 8. lasix 20 mg per ng tube twice a day times seven days. 9. 20 meq per ng tube twice a day times seven days. 10. lopressor 25 mg p.o. twice a day. 11. coumadin 2 mg p.o. q. day times five days; 4 mg p.o. times two days. discharge diagnoses: 1. status post coronary artery bypass graft times three. condition at discharge: good. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery coronary arteriography using two catheters (aorto)coronary bypass of two coronary arteries angiocardiography of left heart structures left heart cardiac catheterization enteral infusion of concentrated nutritional substances diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome unspecified essential hypertension atrial fibrillation occlusion and stenosis of carotid artery without mention of cerebral infarction surgical operation with anastomosis, bypass, or graft, with natural or artificial tissues used as implant causing abnormal patient reaction, or later complication, without mention of misadventure at time of operation cerebral embolism with cerebral infarction iatrogenic cerebrovascular infarction or hemorrhage 

Answer: The patient is high likely exposed to
