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 female who had a new murmur discovered in . the patient had an echocardiogram done at hospital in . this revealed an ejection fraction of approximately 50% and severe aortic stenosis. the patient complains of increasing dyspnea on exertion with one flight of stairs. the patient denies any chest pain, pressure, lightheadedness, nausea or sweating. the patient was referred to our cardiac catheterization laboratory at the hospital. the catheterization was done on . the results of this are as follows: 1. right dominant artery; left anterior descending, tubular 75% lesion; normal right and left heart filling pressures; normal cardiac output. 2. aortic valve disease with severe stenosis. peak gradient across the aortic valve is 60 millimeters of mercury with of 0.85 centimeters squared. the patient was referred to dr. for an aortic valve replacement and coronary artery bypass graft. past medical history: 1. glaucoma. 2. hypercholesterolemia. 3. hypertension. 4. status post appendectomy. 5. status post bilateral cataract surgery. 6. status post left breast biopsy. medications at home: 1. lipitor 40 mg p.o. q. day. 2. hydrochlorothiazide unknown dose. 3. eye drops. allergies: no known drug allergies. review of systems: the patient denies any coughs, chest pain, syncope, palpitations, bleeding disorders, diabetes mellitus, thyroid disease, transient ischemic attack, cerebrovascular accident, claudication and varicosities. the patient endorses dyspnea on exertion. physical examination: on examination, the patient was afebrile; heart rate 70; blood pressure 160/81 on the left and 155/83 on the right. cardiac examination was regular rate and rhythm, s1, s2, with a holosystolic murmur which radiates to the carotids. her lung examination was clear to auscultation bilaterally. the patient was breathing evenly and unlabored. abdominal examination was soft and nontender, nondistended, with positive bowel sounds; no hepatosplenomegaly was appreciated. no costovertebral angle tenderness. extremities were warm and well perfused. no erythema, edema or varicosities were noted. pulse examination: the patient had two plus pulses bilaterally in the carotids, radial, femoral and posterior tibial. neurological examination: cranial nerves ii through xii are grossly intact. laboratory: on admission, white blood cell count 12.6, hematocrit 37.0, platelets 380. pt 12.5, ptt 25.5, inr 1.0. sodium 141, potassium 4.1, chloride 101, bicarbonate 34, bun 20, creatinine 1.0. blood glucose is 98. total bilirubin is 0.6, albumin 4.0, alt 18, ast 18, alkaline phosphatase 113. electrocardiograms done on this date showed normal sinus rhythm at 69 beats per minute with nonspecific lateral st changes; questionable left ventricular hypertrophy. brief hospital course: on , the patient was admitted for coronary artery bypass graft and aortic valve replacement. the patient underwent a bronchoscopy which revealed a normal oropharynx, moderate edema within the larynx, old clots in the trachea, slight aspiration in the main stem bronchi. there were also mucosal abnormalities 2 centimeters below the cords with no acute bleeding and no obvious lesion. the patient underwent her aortic valve replacement and coronary artery bypass graft. the patient had her left internal mammary artery to her left anterior descending and a 19 millimeter pericardial valve placed. the procedure was performed by dr. and assisted by dr. and nurse . the crossclamp time was 77 minutes and the coronary bypass time was 115 minutes. during the bronchoscopy, there was also an evacuation of a tracheal clot. the patient tolerated the procedures well and there were no complications during the surgeries. following a brief stay in the post anesthesia care unit, the patient was transferred to the csru on a phenylephrine and propofol drip. upon arrival in the csru, the patient was noted to have labile blood pressure and was maintained on her neo-synephrine. the patient was weaned off her vent and slowly weaned off her neo-synephrine. on postoperative day number one, the patient was weaned off simp to cpap with the pressure support of 5 and 5. she was started on lopressor and lasix and had one episode of atrial fibrillation. the patient was weaned off of her neo-synephrine and she was able to maintain her blood pressure without any additional pressors. on postoperative day number two, it was noted that the patient had a fairly large amount of secretions and questionable blood tinged sputum. the patient was started on levofloxacin. the patient underwent a second bronchoscopy which revealed a moderate sized blood clot at the left and right main stem bronchi. due to the overly thick secretions and large quantities, the patient was maintained on intubation. the patient was extubated late on postoperative day number two. following extubation, the patient was given aggressive pulmonary toilet which she secreted thick dark red blood clots. the patient was maintained on a face mask and was able to maintain her o2 saturation at greater than 90% while on 50% oxygen. from a cardiovascular standpoint, the patient continued to be in atrial fibrillation while on intravenous lopressor. the patient was placed on nitroglycerin for hypertension at a drip of 0.5 micrograms per kilogram per minute. the patient was given an amiodarone bolus and started on an amiodarone drip for her atrial fibrillation. on postoperative day number three, the patient was weaned down on her nitroglycerin after starting a low dose captopril and lopressor. the patient continued to be weaned off her face mask down to nasal cannula and was able to maintain her oxygen saturations without any difficulty. on this day, the patient was off of her amiodarone drip and placed on amiodarone p.o. the patient continued to have labile blood pressure and her nitroglycerin had to be increased up to 1.5 micrograms per kilogram per minute, although the patient remained in normal sinus rhythm with no ectopy noted. by postoperative day number four, the patient was able to be weaned off all pressors and was labelled to be in normal sinus rhythm and maintained her o2 saturations on small amounts of nasal cannula oxygen. the patient was transferred to the floor on that same day. once the patient reached the floor, the patient was seen by physical therapy. physical therapy stated that after working with her for a couple of sessions, she would be able to be discharged to home. once the patient reached the floor, the remainder of her postoperative course was relatively uneventful. the patient had her pacing wires removed on postoperative day number six and the patient was able to maintain her blood pressure and remain in normal sinus rhythm without any difficulty. the patient was started on coumadin on postoperative day number seven in anticipation of her going home while needing anticoagulation. by postoperative day number eight, the patient was cleared by physical therapy and her inr was in a therapeutic range. her heparin was discontinued and plans were made to discharge the patient to home. physical examination: on discharge, the patient was afebrile with a temperature maximum of 97.4 f.; pulse 70 in sinus rhythm; blood pressure of 119/85; breathing 18; 100% on room air. her labs on discharge were cbc with white blood cell count of 10.9, hematocrit 29, platelets 286. chem-7; sodium 139, potassium 4.9, chloride 102, bicarbonate 32, bun 16, creatinine 1.2, blood glucose 19. pt 19.9, ptt 55.8, inr 2.6. the patient was alert and oriented times three in no apparent distress. her lung examination was clear to auscultation bilaterally breathing even and unlabored. she was in a regular rate and rhythm with s1 and s2 noted. her sternum was stable and incision with steri-strips. the incision was clean, dry and intact. her abdomen was soft, nontender, nondistended, with noticeable bowel sounds. her extremities were warm and well perfused with a one plus pedal edema. discharge disposition: the patient was discharged to home with visiting nurses association nursing provided by visiting nurses association, telephone number . discharge instructions: 1. the patient was instructed to please follow-up with dr. in two to three weeks. 2. the patient was instructed to follow-up with dr. in four weeks. 3. the patient was also instructed to have her inr checked in 24 hours and have the results called in to dr. for further coumadin dosing. condition on discharge: the patient's condition was good. she was afebrile. pain was under control with oral medications, tolerating a regular diet without difficulty and ambulating independently. discharge diagnoses: 1. status post aortic valve replacement. 2. status post coronary artery bypass grafting, lma to left anterior descending. 3. status post postoperative atrial fibrillation. 4. hypercholesterolemia. 5. glaucoma. 6. hypertension. 7. status post appendectomy. 8. status post bilateral cataract surgery. discharge medications: 1. metoprolol 50 mg p.o. twice a day. 2. potassium chloride 20 meq p.o. twice a day for two weeks. 3. percocet one to two tablets p.o. q. four to six hours p.r.n. pain. 4. amiodarone 400 mg p.o. twice a day for three days, then 200 mg twice a day for seven days, and 200 mg q. day times one month. 5. captopril 37.5 mg p.o. three times a day. 6. aspirin 81 mg p.o. q. day. 7. lasix 20 mg p.o. q. day for two weeks. 8. coumadin 2 mg tablets, taken as directed, to maintain goal inr of 2.0 to 2.5. 9. lipitor 40 mg tablets p.o. q. day. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery open and other replacement of aortic valve with tissue graft closed [endoscopic] biopsy of bronchus diagnoses: coronary atherosclerosis of native coronary artery pure hypercholesterolemia unspecified essential hypertension atrial fibrillation aortic valve disorders unspecified glaucoma
