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: patient recorded as having no known allergies to drugs attending: chief complaint: aortic stenosis/ regurgitation major surgical or invasive procedure: aortic valve replacement (21mm st. porcine) history of present illness: this 86 year old white female has known aortic stenosis with progressive dyspnea on exertion and fatigue over 7 months. she has previously undergone catheterization to demonstrate clean coronaries, despite a prior anterior infaction in . she is admitted now for valve replacement. past medical history: coronary artery disease s/p ami ' ischemic cardiomyopathy (ef 35-40%) aortic stenosis/insufficiency hypertension hyperlipidemia diverticulitis past surgical history: right hip replacement s/p fracture(mva)' bowel resection(diverticular dz)-' incisional hernia repair ' bilat cataract removal ovarian cyst removal social history: race: caucasian last dental exam: 1 month ago lives with: husband occupation: retired college professor/-education() tobacco:quit 40 yrs ago, previously smoked 1ppwk x20yrs etoh:1 drink every other month family history: non-contributory physical exam: pulse: 54 resp: 16 o2 sat: 98%-ra b/p right: 160/72 left: height: 65 in weight: 176 lbs general: skin: dry intact heent: perrla eomi mmm, normal oropharynx neck: supple full rom , no jvd or lymphadenopathy chest: lungs clear bilaterally heart: rrr irregular murmur: blowing murmur abdomen: soft non-distended non-tender +bowel sounds extremities: warm , well-perfused edema: none varicosities: minimal neuro: grossly intact, a&o x3-mae, nonfocal exam pulses: femoral right: 2+ left: 2+ dp right: 1+ left: 1+ pt : 1+ left: 1+ radial right: 2+ left: 2+ carotid bruit: radiated murmur right: left: pertinent results: 02:10am blood wbc-13.1* rbc-3.41* hgb-10.1* hct-30.2* mcv-89 mch-29.7 mchc-33.4 rdw-14.4 plt ct-126* 06:20am blood na-135 k-4.5 cl-101 06:40am blood wbc-10.0 rbc-3.32* hgb-9.9* hct-29.6* mcv-89 mch-29.9 mchc-33.5 rdw-14.0 plt ct-122* 12:30pm blood wbc-6.9 rbc-2.57*# hgb-7.7*# hct-22.4*# mcv-87 mch-29.9 mchc-34.2 rdw-13.4 plt ct-122*# 06:40am blood glucose-113* urean-26* creat-1.1 na-138 k-4.2 cl-103 hco3-28 angap-11 01:35pm blood urean-10 creat-0.7 na-141 k-4.3 cl-115* hco3-22 angap-8 echocardiography report , (complete) done at 11:46:35 am final referring physician information , r. , division of cardiothorac , status: inpatient dob: age (years): 86 f hgt (in): bp (mm hg): / wgt (lb): hr (bpm): bsa (m2): indication: avr icd-9 codes: 786.05, 786.51, 424.1, 424.0 test information date/time: at 11:46 interpret md: , md test type: tee (complete) son: , md doppler: full doppler and color doppler test location: anesthesia west or cardiac contrast: none tech quality: adequate tape #: 2010aw-1: machine: echocardiographic measurements results measurements normal range left ventricle -

50 %). right ventricular chamber size and free wall motion are normal. there are complex (>4mm) atheroma in the descending thoracic aorta. the number of aortic valve leaflets cannot be determined. the aortic valve leaflets are severely thickened/deformed. there is critical aortic valve stenosis (valve area <0.8cm2). moderate (2+) aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. mild (1+) mitral regurgitation is seen. there is no pericardial effusion. post-cpb: the patient is a-paced, on no inotropes. preserved biventricular systolic fxn. there is a prosthetic aortic valve with no leak and no regurgitation. mean residual gradient = 10 mmhg. no mr. . aorta intact. i certify that i was present for this procedure in compliance with hcfa regulations. electronically signed by , md, interpreting physician 13:01 brief hospital course: following admission she went to the operating room where aortic valve replacement was undertaken. she operative note for details. she weaned from bypass easily on propofol alone. she awoke anxious but intact, requiring nitroglycerin intravenously for bp control. she was extubated on pod 1 and oral agents (valsartan and lopressor). diuresis towards her preoperative weight was begun and she transferred to the floor on pod 2. physical therapy worked with her for strength and mobility. cts and temporary pacing wires were removed per protocols. she had a brief episode of atrial fibrillation in the 140s on pod 4, which was well tolerated. this was treated with iv lopressor and amiodarone with restoration of sinus rhythm. she remained volume overloaded and was discharged to rehab on iv lasix for 1 week. on pod 5 she was ready for discharge and went to rehab a mwmc in . medications on admission: metoprolol er 25 daily simvastatin 40 daily zetia 10 daily ntg-sl-prn aspirin 325 daily diovan 320 daily fish oil vitamin e 400iu daily vitamin d 500mg daily discharge medications: 1. acetaminophen 325 mg tablet sig: two (2) tablet po q4h (every 4 hours) as needed for pain. 2. ezetimibe 10 mg tablet sig: one (1) tablet po daily (daily). 3. simvastatin 40 mg tablet sig: one (1) tablet po daily (daily). 4. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). 5. magnesium hydroxide 400 mg/5 ml suspension sig: thirty (30) ml po hs (at bedtime) as needed for constipation. 6. valsartan 160 mg tablet sig: two (2) tablet po daily (daily). 7. tramadol 50 mg tablet sig: one (1) tablet po q6h (every 6 hours) as needed for pain. 8. amiodarone 200 mg tablet sig: as directed tablet po bid (2 times a day): 1 tab(200mg) for two weeks then one tab(200mg) daily. 9. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). 10. psyllium packet sig: one (1) packet po bid (2 times a day) as needed for constipation. 11. metoprolol tartrate 25 mg tablet sig: 0.5 tablet po bid (2 times a day). 12. furosemide 10 mg/ml solution sig: four (4) injection twice a day for 1 weeks: 40mg iv lasix x 1 week, then re-evaluate. 13. potassium chloride 20 meq tab sust.rel. particle/crystal sig: one (1) tab sust.rel. particle/crystal po q12h (every 12 hours) for 1 weeks. discharge disposition: extended care facility: tba discharge diagnosis: aortic stenosis/reguritation hypertension s/p aortic valve replacement s/p right total hip arthroplasty ischemic cardiomyopathy coronary artery disease s/p colon resection for diverticular disease s/p herniorraphy s/p cataract extractions hyperlipidemia s/p ovarian cystectomy discharge condition: alert and oriented x3, nonfocal ambulating with steady gait incisional pain managed with ultram incisions: sternal -
