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: dyspnea on exertion major surgical or invasive procedure: aortic valve replacement with a size 23 st. mechanical valve. ascending aortic replacement with a size 26 gelweavegraft. coronary artery bypass grafts x1 with the left internal mammary artery to left anterior descending artery left side thoracentesis history of present illness: this 57 year old patient with symptom of dyspnea on exertion in the past year which was progressively getting worse was investigated. he was known to have aortic stenosis since childhood and was asymptomatic until one year ago. current investigation with an echocardiogram showed severe aortic stenosis with depressed left ventricular function and coronary angiogram revealed critical aortic stenosis along with disease in the left anterior descending artery and a small non-dominant right coronary artery. he was also noticed to have dilated ascending aorta above the sinotubular junction. the aorta was normal size just below the arch. his aortic valve pathology was basically a calcified and bicuspid aortic valve. he was electively admitted for aortic valve replacement, ascending aortic replacement and coronary artery bypass grafting. past medical history: coronary artery disease, aortic stenosis, ascending aortic aneurysm, history of gi bleed social history: mr. works as a construction worker and owns his own business. he has a remote history of smoking, but quit many years ago. patient states that he consumes alcohol socially and denies illicit drug use. family history: significant for a father who underwent angioplasty in his 70's for coronary artery disease, but there is no other family history of coronary or valvular disease. physical exam: vitals: t 98 hr 82 bp 140/88 rr 20 awake and alert x3, mae, follows commands perrl, eomi, mmm neck supple, no jvd rrr, normal s1 and s2, + blowing murmur abdomen soft, nt/nd, nabs ext warm, no varicosities, 2+ pulses in radial, dp and pt pulses bilaterally pertinent results: 09:20am blood hct-27.3* 05:50am blood pt-27.7* inr(pt)-2.9* 09:20am blood urean-21* creat-1.2 na-138 k-3.5 05:10am blood mg-2.2 brief hospital course: the patient was admitted to the hospital. on , the patient went to the operating room for an avr, ascending aorta replacement and cabg. please see separate operative note for details. the patient tolerated this procedure well. after surgery, the patient was transferred to the csru, where he was kept intubated overnight. one the first night after surgery, the patient became tachycardic in atrial fibrillation. an ekg was obtained, and this showed precordial st-segment depressions, which appeared to resolve with control of the heart rate with administration of iv amiodarone. follow-up ekgs showed sinus rhythm and failed to demonstrate any ongoing st segment depression. on post-op day #1, the vent was weaned and the patient was extubated. a follow-up echocardiogram failed to reveal any pathology. on post-op day #2, the patient's lopressor and ace inhibitor were increased and the patient was transitioned to po amiodarone. the patient was transferred to the floor the next day. on post-op day #4, the patient's inr was found to be 2.8, and his anticoagulation was held so that his pacing wires could be removed. on post-op day #7, the patient's inr was found to be 1.7. a chest xray at that time showed a left pleural effusion, which was subsequently tapped to drain approximately 1000cc fluid. a post-thoracentesis chest xray showed resolution of the pleural effusion. the pacing wires were eventually removed without complication. due to a subtherapeutic prothrombin time, he was temporarily heparinized. warfarin therapy was resumed and dosed for a goal inr between 2.5 - 3.0. the rest of his hospital course was uneventful and he was discharged to home on postoperative day 12. dr. will monitor his warfarin as an outpatient. medications on admission: aspirin 325 mg qd, advil prn discharge medications: 1. oxycodone-acetaminophen 5-325 mg tablet sig: one (1) tablet po q4h (every 4 hours) as needed for pain. disp:*40 tablet(s)* refills:*0* 2. 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* 3. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 4. amiodarone 200 mg tablet sig: one (1) tablet po bid (2 times a day) for 1 weeks: then decrease to 1 tablet daily until d/c'd by cardiologist. disp:*60 tablet(s)* refills:*2* 5. pantoprazole 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q24h (every 24 hours). disp:*30 tablet, delayed release (e.c.)(s)* refills:*2* 6. potassium chloride 10 meq capsule, sustained release sig: two (2) capsule, sustained release po bid (2 times a day) for 7 days. disp:*28 capsule, sustained release(s)* refills:*0* 7. atorvastatin 10 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 8. clopidogrel 75 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 9. metoprolol tartrate 25 mg tablet sig: three (3) tablet po bid (2 times a day). disp:*180 tablet(s)* refills:*2* 10. furosemide 20 mg tablet sig: one (1) tablet po bid (2 times a day) for 7 days. disp:*14 tablet(s)* refills:*0* 11. warfarin 1 mg tablet sig: one (1) tablet po once a day for 1 days: take 1mg today, then inr to be checked, and dosed by dr.. disp:*90 tablet(s)* refills:*0* discharge disposition: home with service facility: all care vna of greater discharge diagnosis: coronary artery disease, aortic stenosis, dilated ascending aorta -
