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: decreasing exercise tolerance; exertional angina major surgical or invasive procedure: redo sternotomy and aortic valve replacement(27-mm st. epic tissue) history of present illness: this 82 year old white male underwent coronary bypass in and subsequent stenting in . he has a history of aortic stenosis followed by echocardiograms. he was referred for surgical evaluation and admitted now for surgery. past medical history: aortic stenosis coronary artery disease s/p coronary artery bypass graft x 5 s/p coronary stenting hypertnesion s/p gastrointestinal bleed nephrolithiasis dyslipidemia psoriasis arthritis s/p coronary artery bypass graft x 5 s/p appendectomy s/p cervical laminectomy s/p lumbar laminectomy s/p tonsillectomy s/p hernia repair social history: race:caucasian last dental exam:dental clearance in office chart lives with:wife occupation:retired-telephone worker tobacco:none etoh:none x40yrs rec drugs: none family history: sibling died of mi at 58 physical exam: admission: pulse: 63 resp: o2 sat: 99% ra b/p right: left: 158/65 height: 70" weight: 180 general:nad;occ. cough skin: dry intact heent: perrla eomi ;anicteric sclera neck: supple full rom chest: lungs clear bilaterally heart: rrr irregular murmur: blowing murmur radiates to carotids abdomen: soft non-distended non-tender bowel sounds + extremities: warm , well-perfused edema: none varicosities: minimal bilat; right saphenectomy scars groin to ankle well-healed neuro: grossly intact;nonfocal exam; moves bue strengths; ble strengths pulses: femoral right: 2+ left: 2+ dp right: 1+ left: 1+ pt : 1+ left: 1+ radial right: 2+ left: 2+ carotid bruit : murmur transmits bilat. carotids pertinent results: echo: prebypass: there is mild symmetric left ventricular hypertrophy. overall left ventricular systolic function is normal (lvef=70%). right ventricular chamber size and free wall motion are normal. there are three aortic valve leaflets. the aortic valve leaflets are severely thickened/deformed. there is severe aortic valve stenosis (valve area 0.8-1.0cm2). moderate to severe (3+) aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. mild to moderate (+) mitral regurgitation is seen. there is mild tricuspid regurgitation. there is no pericardial effusion. postbypass: the patient is on infusions of phenylephrine and epinephrine and is a-paced at a rate of 80 bpm. left ventricular systolic function is borderline hyperdynamic. there are no regional wall motion abnormalities. the bioprosthetic aortic valve is well-seated, with a trace amount of central aortic insufficiency. the post-replacement aortic valve peak gradient is 19 mmhg. mitral regurgitation has improved to mild (1+). aortic contours are normal. 03:57am blood wbc-7.5 rbc-3.20* hgb-9.9* hct-28.5* mcv-89 mch-30.9 mchc-34.7 rdw-15.0 plt ct-69* 02:00pm blood wbc-8.3# rbc-2.35*# hgb-7.3*# hct-21.8*# mcv-93 mch-30.9 mchc-33.3 rdw-13.9 plt ct-137* 05:41am blood glucose-105* urean-23* creat-0.8 na-133 k-3.8 cl-97 hco3-27 angap-13 02:31pm blood na-133 k-4.2 cl-97 03:34pm blood urean-14 creat-0.8 na-142 k-4.1 cl-112* hco3-23 angap-11 inr 2.0 (2 mg couamdin) inr 1.8 ( 1mg coumadin) brief hospital course: mr. was a same day admit after undergoing preoperative work-up as an outpatient. on he was brought directly to the operating room where he underwent a redo-sternotomy and aortic valve replacement. please see operative report for surgical details. following surgery he was transferred to the cvicu for invasive monitoring in stable condition. within 24 hours he was weaned from sedation, awoke neurologically intact and extubated. cts and pacing wirtes were removed per protocols. beta blockers and diuretics were instituted postoperatively for rate control and diuresis. coumadin was resumed due to the presence of bare metal stents placed previously. physical therapy worked with him for mobility and strength. he made good progress but was not conditioned enough to return directly home, so rehabilitation screening was done and he was discharged to health center for rehabilitation. discharge medications and restrictions were as outlined in the summary elsewhere. wound were clean and healing well. the inr goal was 2-2.5 for afib and bare metal stents. of note, he has had a history of gib from asa- please giuaic stools. medications on admission: azithromycin (z-pack -completes ) tessalon perles mvi daily vit. c 500 mg daily vitamin e 400 units daily nexium 40 mg dovonex 0.005% one appl. daily taclonex 0.064%-0.005% one appl. daily hctz 25 mg daily welchol 1250 mg niaspan er 500 mg qhs asa 81 mg daily ramipril 10 mg daily toprol xl 25 mg daily clobetasol 0.05% one applic daily metronidaze ?
