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: allergies: no known allergies / adverse drug reactions attending: chief complaint: syncope major surgical or invasive procedure: : aortic valve replacement with a size 19-mm - magna tissue valve. history of present illness: 84 year old female who was brought to the ed after syncope/fall, and is admitted to medicine due to elevated troponin. at her baseline, she feels well and is active, able to climb a few flights of stairs without complaints. she was brought to ed for further evaluation. during admission an echocardiogram was done and she was found to have aortic stenosis =0.4 and is now being referred to cardiac surgery for an aortic valve replacement. past medical history: -s/p fall a few years ago with small sah fall social history: -home: married, lives with husband. three grown kids. -occupation: retired dressmaker. -tobacco: none -etoh: none -illicits: none family history: no mi, stroke. mother died of "lung problems," father died of colon cancer. physical exam: admission exam: vs -

14 mm hg. 3. no other change in an y other valve structure and function. . carotid u/s: mild heterogeneous plaque is seen bilaterally at the carotid bulb and the proximal internal carotid arteries. the peak systolic velocity and right internal carotid artery ranges from 77 to 102 cm/sec and in the left internal carotid artery from 72 to 96 cm/sec. the peak systolic velocity in the right common carotid artery 71 cm/sec and in the left common carotid artery is 80 cm/sec. bilateral external carotid arteries are patent. there is antegrade flow in the bilateral vertebral arteries. the ica to cca ratio on the right is 1.4 and on the left was 1.2. . cath: 1. no angiographically-apparent coronary artery disease. 2. severe aortic stenosis. 3. no pulmonary arterial hypertension. 4. slightly depressed cardiac output. . head ct: there is no evidence of hemorrhage, edema, mass effect, or territorial infarction. the ventricles and sulci are mildly prominent consistent with atrophy. there is a small hypodensity in the left basal ganglia which could be an old lacunar infarct or virchow- vascular space. the visualized paranasal sinuses, mastoid air cells, and middle ear cavities are clear. the osseous structures are intact. there is no fracture. . 01:00pm blood wbc-6.8 rbc-4.04* hgb-12.5 hct-37.2 mcv-92 mch-30.9 mchc-33.6 rdw-12.4 plt ct-250 05:37am blood wbc-6.8 rbc-3.54* hgb-10.9* hct-32.5* mcv-92 mch-30.6 mchc-33.4 rdw-13.0 plt ct-274# 01:00pm blood pt-12.3 ptt-27.8 inr(pt)-1.0 06:44pm blood pt-13.7* ptt-47.6* inr(pt)-1.2* 01:00pm blood glucose-156* urean-15 creat-0.8 na-139 k-3.7 cl-103 hco3-27 angap-13 04:40am blood glucose-104* urean-16 creat-0.8 na-139 k-4.4 cl-102 hco3-31 angap-10 05:37am blood urean-21* creat-1.1 na-138 k-4.4 cl-99 03:48am blood calcium-8.1* phos-3.1 mg-2.0 07:30am blood triglyc-93 hdl-73 chol/hd-2.7 ldlcalc-108 08:00am blood %hba1c-5.5 eag-111 brief hospital course: the patient was admitted to the hospital after syncope/fall, to medicine service for elevated troponin. during admission she underwent an echocardiogram and she was found to have aortic stenosis with =0.4cm2. in addition she underwent a cardiac cath and complete surgical work-up. on she was brought to the operating room where the patient underwent aortic valve replacement with a size 19-mm - magna tissue valve. please see operative note for surgical details. overall the patient tolerated the procedure well and post-operatively was transferred to the cvicu in stable condition for recovery and invasive monitoring. pod 1 found the patient extubated, alert and oriented and breathing comfortably. the patient was neurologically intact and hemodynamically stable on no inotropic or vasopressor support. beta blocker was initiated and the patient was gently diuresed toward the preoperative weight. the patient was transferred to the telemetry floor for further recovery. chest tubes and pacing wires were discontinued without complication. the patient was evaluated by the physical therapy service for assistance with strength and mobility. on post-op day 5 she had a brief burst of atrial fibrillation which was treated with beta-blockers and amiodarone. she converted to sinus rhythm and remained in sr at discharge. by the time of discharge on pod 7 the patient was ambulating with assistance, the wound was healing and pain was controlled with oral analgesics. the patient was discharged to rehab in good condition with appropriate follow up instructions. medications on admission: none discharge medications: 1. pantoprazole 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q24h (every 24 hours). 2. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 3. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). disp:*30 tablet, delayed release (e.c.)(s)* refills:*2* 4. oxycodone-acetaminophen 5-325 mg tablet sig: 1-2 tablets po q4h (every 4 hours) as needed for pain. disp:*30 tablet(s)* refills:*0* 5. metoprolol tartrate 25 mg tablet sig: three (3) tablet po bid (2 times a day). disp:*180 tablet(s)* refills:*2* 6. furosemide 20 mg tablet sig: one (1) tablet po once a day for 7 days. disp:*7 tablet(s)* refills:*0* 7. potassium chloride 20 meq packet sig: one (1) packet po once a day for 7 days. disp:*7 packet(s)* refills:*0* 8. amiodarone 200 mg tablet sig: two (2) tablet po bid (2 times a day): please take two 200mg tablets twice daily for 5 days. then one 200mg tablet twice daily for 7 days. then one 200mg table once daily until stopped by cardiologist. discharge disposition: extended care facility: -
