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 an 81-year-old female patient, with hospitalization earlier this year for congestive heart failure, pulmonary edema and palpitations. she has also had several hospitalizations in the past 4-5 years for congestive heart failure. the patient has been followed by echocardiograms for her mitral regurgitation, and most recent echo from of this year revealed 4 plus mitral regurgitation with mitral annular calcification, as well as a left ventricular ejection fraction of 55 percent. the patient subsequently underwent cardiac catheterization which revealed two-vessel coronary artery disease, a left ventricular ejection fraction of 65 percent, and severe pulmonary hypertension. the patient was referred for mitral valve replacement and coronary artery bypass graft, as well as a maze procedure for atrial fibrillation. past medical history: atrial fibrillation. hypothyroidism. status post permanent pacemaker placement. congestive heart failure. hypertension. ?tia approximately 10 years ago. osteoarthritis. mitral regurgitation. remote lower gi bleed. status post umbilical hernia repair. kyphosis. status post breast biopsy. status post right ankle cyst removal. left achilles tendon repair. bilateral total knee replacements. cataract surgery. medications on admission: 1. enteric-coated aspirin 81 mg po once daily. 2. levoxyl 0.05 mg po once daily. 3. metoprolol 50 mg po bid. 4. lasix 80 mg once daily. 5. potassium chloride 10 meq po once daily. 6. verapamil 120 mg po once daily. 7. lipitor 40 mg po once daily. 8. pepcid 10 mg po once daily. 9. calcium supplements. 10.zestril 5 mg po once daily. allergies: keflex which causes nausea and vomiting. she is also allergic to shellfish. social history: the patient does not smoke and has rare alcohol intake. hospital course: the patient was admitted to the hospital on , where she was taken directly to the operating room by dr. , where she underwent a coronary artery bypass graft x 2 with a lima to the lad and a saphenous vein to the om. she also had a mitral valve repair with a 28 mm ring, as well as a maze procedure. postoperatively, she was on epinephrine, propofol and neo-synephrine drips, and was transported from the operating room to the cardiac surgery recovery unit in good condition. the patient was extubated on the night of surgery and remained on epinephrine, neo-synephrine drips through the course of that night. she also had a metabolic acidosis which was treated with sodium bicarbonate. on postoperative day 1, she remained hemodynamically stable and weaned off of her epinephrine and propofol drips. on postoperative day 2 had begun with diuresis, still remained somewhat hypotensive on iv neo-synephrine drip. her pulmonary artery catheter was discontinued, as were her epicardial wires and chest tubes. her neo-synephrine was ultimately weaned off on postoperative day 3, after which she was transferred from the cardiac surgery recovery unit to the postoperative telemetry floor. the patient was started on coumadin on postoperative day 3 for her history of atrial fibrillation, status post maze procedure. she had remained ventricularly paced at that time. she had progressed well from a hemodynamic and respiratory standpoint, although was slow to progress with physical mobility and ambulation. the patient had remained in normal sinus rhythm, or being paced by her permanent pacemaker, tracking her native atrial rate, until when she was noted to be in atrial fibrillation early in the morning with a rate between 100 and 120. her blood pressure remained stable throughout this time, and her lopressor was increased, as was her amiodarone. she continued to progress slowly from a physical therapy and rehabilitation standpoint, although remained in atrial fibrillation, was anticoagulated for it, and her rate was controlled. she has had intermittent atrial fibrillation this morning with ventricular response rate in the 80s-90s. she was going to be discharged today to rehabilitation facility with of hearts event monitor for her amiodarone loading, and she was also going to remain on coumadin for her atrial fibrillation. condition on discharge: neurologically, she was alert and oriented. her lungs were clear to auscultation bilaterally. her cardiac exam was regular rate and rhythm. abdomen was soft, nontender, nondistended. her steri-strips to her sternal incision were clean, dry and intact, as was her right lower extremity incision. she had some edema of her right lower extremity and some peripheral edema remained bilaterally only when her legs are in a dependent position, but she was continuing to be diuresed. the patient was scheduled to have a chest x-ray prior to discharge today, and the results of that were still pending. discharge medications: 1. aspirin enteric-coated 81 mg po once daily. 2. potassium chloride 20 meq po bid. 3. protonix 40 mg po once daily. 4. lipitor 40 mg po once daily. 5. levothyroxine 50 mcg po once daily. 6. lasix 40 mg po bid. 7. percocet 5/325, 1-2 tablets po q 4-6 h prn pain. 8. continue amiodarone 400 mg po tid for 1 week and then decrease it to 400 mg for 1 week, then 400 mg once daily for 1 week, then 200 mg once daily, or until discontinued by dr. . 9. lopressor 25 mg po bid. 10.senna 1 tablet po bid. 11.coumadin 1 mg po today, on , and tomorrow, on . she is then to have an inr checked in rehab on , and her coumadin dose should be adjusted accordingly for a target inr of 2.0-2.5. the patient's inr yesterday, , was 2.1, and she received 2 mg, and today her inr was 2.5, and she will receive 1 mg today. follow up: the patient is to follow-up with dr. , cardiac surgery, for postoperative check in 4 weeks. she is also to follow-up with dr. in weeks. dr. office will be dosing her coumadin, as well. dr. office telephone number is . , m.d. procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery excision or destruction of other lesion or tissue of heart, open approach (aorto)coronary bypass of one coronary artery annuloplasty transfusion of packed
