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: a 70-year-old woman with a history of silent myocardial infarction echocardiogram from revealed an ejection fraction of 55% with distal septal and apical hypokinesis and mildly dilated lv and mild mitral regurgitation. over the past several months, the patient has noticed that she is having intermittent chest pain, can occur at any time. she has taken sublingual nitroglycerin in the past with relief of these symptoms. she has also noticed that she is having shortness of breath with a minimal amount of walking. she reports occasional shortness of breath at rest. on of she had an exercise tolerance test, 3 minutes protocol, 70% maximum heart rate achieved. she had no chest pain, electrocardiogram without ischemic electrocardiogram changes. imaging revealed a large area of inferior apical infarct with moderate peri-infarct ischemia. there was left ventricular dilatation at rest worsening with stress. there was also septal dyskinesis in the lateral wall, hypokinesis. past medical history: 1. coronary artery disease, status post silent myocardial infarction 2. hypertension 3. hypercholesterolemia 4. noninsulin dependent diabetes mellitus 5. gastroesophageal reflux disease 6. cataracts past surgical history: bilateral broken ankles, t&a and dilatation and curettage allergies: no known drug allergies. medications prior to admission: 1. aspirin 81 mg qd 2. glucophage 1000 mg 3. glucotrol xl 10 mg qd 4. prilosec 20 mg 3 to 4x a week 5. 60 mg 6. multivitamin 1 qd 7. pravachol 40 mg qd 8. atenolol 50 mg qd 9. accupril 20 mg qd lab data prior to admission: white count 11.1, hematocrit 30.3, platelets 198. sodium 144, potassium 4.0, chloride 108, co2 27, bun 19, creatinine 0.9. social history: divorced. she lives with her son. she is the caregiver, as the son has cerebral palsy. hospital course: the patient was admitted for cardiac catheterization. she was brought to the cardiac catheterization lab where she underwent cardiac catheterization. please see catheterization report for full details. in summary, catheterization showed an ejection fraction of 20%, left main 80%, lad serial 80% to 90% lesions, left circumflex with diffuse disease and an rca with 80% lesion. following the catheterization, cardiothoracic surgery was consulted. the patient was seen and accepted for coronary artery bypass grafting. on , she was brought to the operating room at which time she underwent coronary artery bypass grafting x4. please see the operating room report for full details. in summary, she had a coronary artery bypass graft x4 with a left internal mammary artery to the lad and saphenous vein graft to om and ramus sequentially and saphenous vein graft to the pl. she was transferred from the operating room to the cardiothoracic intensive care unit. at the time of transfer, she had milrinone at 0.5 mcg per kg per minute and neo-synephrine at 1 mcg per kg per minute. she did well in the immediate postoperative period. her anesthesia was reversed. she was weaned from the ventilator and successfully extubated. on postoperative day 1, the patient was weaned from her milrinone. she did, however, require neo-synephrine to maintain an adequate blood pressure. also, on postoperative day 1, the patient experienced an episode of atrial fibrillation. at that time, she was started on amiodarone and electrophysiology was consulted because the patient had been noted to have sinus bradycardia with a rate of 40 prior to her surgery. in addition, on postoperative day 1, the patient's chest tubes were discontinued. on postoperative day 2, the patient was weaned successfully from her neo-synephrine infusion. the patient remained in atrial fibrillation and with the assistance of anesthesia the patient was cardioverted with 150 joules to a sinus bradycardia with a rate of 35 to 40. she remained in the intensive care unit, given her relative bradycardia. for the next several days, the patient remained in the intensive care unit to monitor her heart rate and rhythm. during that time, she continued to receive amiodarone and she remained in sinus bradycardia with a rate between 35 and 55. on postoperative day 5, it was felt that the patient was stable and ready to be transferred from the intensive care unit to plastics for continuing postoperative care and cardiac rehabilitation. postoperative day 7, the patient's amiodarone was discontinued, given her continuing bradycardia. on postoperative day 8, the patient was noted to be in a sinus rhythm with a rate of 55 to 60. postoperative day 9, the patient was noted to be back in atrial fibrillation with a heart rate of 90 to 110. low dose beta blockers were started at that time and during the course of that day, the patient again converted back to a sinus rhythm with a rate of 70 beats per minute on lopressor 25 mg . after consultation with electrophysiology and given that patient tolerated her arrhythmias well, it was decided that there was no urgent indication for intervention on the part of pacemaker or aicd placement/ep studies. after consultation with ep and the patient, it was decided to discharge the patient to a rehabilitation center on low dose beta blockers and coumadin with a target inr of 2 and that the patient would return in one month for ep studies plus or minus pacemaker and aicd placement. on postoperative day 11, it was decided that the patient was stable and ready for discharge to rehabilitation. at the time of discharge, the patient's physical exam is as follows: vital signs: temperature 98.6??????, heart rate 75 sinus rhythm, blood pressure 126/78, respiratory rate 20, o2 saturation 95% on room air. her weight preoperatively is 85.8 kg. at discharge it is 73.1 kg. lab data on day of discharge: white count 11.2, hematocrit 33.2, platelets 371,000. pt of 17.1. ptt is 31.6 and inr is 2.1. sodium 140, potassium 4.3, chloride 102, co2 26, bun 24, creatinine 1.1, glucose 60. physical exam: general: alert and oriented x3, moves all extremities, follows commands. respiratory: breath sounds clear to auscultation bilaterally. heart: heart sounds regular rate
