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: mitral valve prolapse major surgical or invasive procedure: - mitral valve replacement with a size 33mm thermafix pericardial valve and single vessel coronary artery bypass graft, saphenous vein graft to the obtuse marginal artery. history of present illness: this 60 year-old patient with a known history of mitral regurgitation/mitral valve prolapse for many years developed increasing symptoms of fatigue and shortness of breath. he also admits to intermittent chest pain. a recent cardiac echocardiogram showed severe mitral regurgitation and coronary angiogram showed single vessel disease in the circumflex coronary artery. the valve pathology was mainly myxomatous valve with severe regurgitation. he was electively admitted for mitral valve repair or replacement and coronary artery bypass grafting. past medical history: mitral valve prolapse, hypertension, hyperlipidemia, prior back surgery, history of amarosis fugax social history: quit tobacco over 25 years ago. he denies excessive etoh. he is married and lives with his wife. family history: both parents died in their 90's. physical exam: general: well developed male in nad heent: oropharynx benign neck: supple, no jvd heart: regular rate, normal s1s2, 3/6 systolic murmur llsb lungs: clear bilaterally abdomen: soft, nontender, no pulsatile masses, normoactive bowel sounds ext: warm, no edema or varicosities pulses: 1+ distally neuro: alert and oriented, no focal deficits noted pertinent results: 05:50am blood hct-31.6* 09:50am blood wbc-10.3 rbc-3.66* hgb-11.5* hct-31.6* mcv-86 mch-31.5 mchc-36.4* rdw-12.7 plt ct-261 04:50pm blood wbc-9.3# rbc-2.92* hgb-9.1* hct-25.4* mcv-87 mch-31.1 mchc-35.7* rdw-12.4 plt ct-132* 05:45am blood pt-13.4* ptt-27.3 inr(pt)-1.2 09:50am blood glucose-123* urean-25* creat-1.0 na-137 k-4.0 cl-96 hco3-27 angap-18 04:37pm blood urean-19 creat-0.9 cl-108 hco3-22 brief hospital course: mr. was admitted and underwent a mitral valve replacement and single vessel coronary artery bypass grafting - see operative note for details. surgery was uneventful and he was brought to the csru for invasive monitoring. he experienced a postoperative coagulopathy that improved after multiple blood products. he remained hemodynamically stable. by postoperative day one, he awoke neurologically intact and was extubated. he weaned from inotropic support without difficulty. on postoperative day two, chest tubes were removed and he transferred to the sdu. over several days, he made clinicl improvements with diuresis. he tolerated beta blockade and initially maintained a normal sinus rhythm. unfortunately, he experienced intermittent fevers. his white count remained normal. fever workup revealed a urinary tract infection as a culture grew out enterobacter. he started on appopriate antibiotics. blood cultures remained negative. over several days, his fevers resolved. on postoperative day seven, he experienced rapid atrial fibrillation. he was therefore temporarily anticoagulated with heparin and started on amiodarone. beta blockade was advanced for rate control. within 24 hours, he converted back to a normal sinus rhythm. no further atrial arrhythmias were noted for the remainder of his hospital stay. heparin was discontinued as medical therapy was optimized. he was cleared for discharge to home on postoperative day nine. at discharge, his bp was 106/74, hr sinus 80's with room air saturations of 96%. his incisions were clean and his chest x-ray was notable for only small bilateral pleural effusions. medications on admission: lisinopril, plavix 75 , 325 qd, protonix, crestor, zetia discharge medications: 1. metoprolol tartrate 25 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*2* 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. clopidogrel 75 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 5. oxycodone-acetaminophen 5-325 mg tablet sig: 1-2 tablets po q4h (every 4 hours) as needed for pain. disp:*60 tablet(s)* refills:*0* 6. ezetimibe 10 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 7. rosuvastatin 5 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 8. 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* 9. furosemide 40 mg tablet sig: one (1) tablet po daily (daily) for 2 weeks. disp:*14 tablet(s)* refills:*0* discharge disposition: home with service facility: vna discharge diagnosis: mitral valve prolapse and mitral regurgitation, coronary artery disease, hypertension, hyperlipidemia, postoperative atrial fibrillation discharge condition: good discharge instructions: if you have chest pain, difficulty breathing, persistent nausea/vomiting, fevers/chills, or redness/oozing from your incision site, seek immediate medical attention. followup instructions: follow up with dr. in weeks, call for an appt. follow up with dr. or (cardiologist) - call for appt. follow up with dr. in 4 weeks - call for an appt. procedure: extracorporeal circulation auxiliary to open heart surgery (aorto)coronary bypass of one coronary artery open and other replacement of mitral valve with tissue graft transfusion of packed cells transfusion of other serum transfusion of platelets continuous intra-arterial blood gas monitoring diagnoses: coronary atherosclerosis of native coronary artery mitral valve disorders unspecified essential hypertension cardiac complications, not elsewhere classified atrial fibrillation personal history of tobacco use other and unspecified hyperlipidemia hemorrhage complicating a procedure other and unspecified coagulation defects
