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: shortness of breath major surgical or invasive procedure: coronary artery bypass graft x 4 (lima to lad, svg to ramus, svg to om1 to om2), mitral valve replacement (31mm st. porcine valve), atrial septal defect closure history of present illness: 75 y/o male with significant cardiac history since . since that time he has been followed for his mitral regurgitation and coronary disease. he developed atrial fibrillation in with episodes of congestive heart failure requiring diuresis. his most recent cath revealed three vessel coronary disease and echo showed severe mitral regurgitation. past medical history: coronary artery disease s/p myocardial infarction w/ stenting/ptca , mitral regurgtation, atrial fibrillation s/p cardioversion , hyperlipidemia, hypertension, diabetes mellitus, congestive heart failure, chronic obstructive pulmonary disease, stroke , renal insufficiency, back pain, s/p icd/ppm placement, s/p lens implant ou , s/p bilaterala inguinal hernia repair, s/p polypectomy social history: quit smoking 15 yrs ago after ppd x 50 yrs. 1 etoh drink/wk. family history: nc physical exam: vitals: 60 16 98/50 70" 178# general: wdwn pale appearing male in nad skin: pale, w/d intact heent: oropharynx benign, eomi, ncat neck: supple, from, no jvd lungs: diminished bs at bases, delayed exp heart: regular rate and rhythm 1-2/6 late systolic murmur abdomen: soft, nontender with normoactive bowel sounds ext: warm, trace to 1+ edema pulses: + distally neuro: alert and oriented, cn 2- 12 grossly intact, no focal deficits noted pertinent results: 04:55pm blood wbc-5.8 rbc-3.39* hgb-9.8* hct-30.4* mcv-90 mch-28.8 mchc-32.1 rdw-18.6* plt ct-204 04:55pm blood pt-17.9* ptt-42.2* inr(pt)-1.6* 04:55pm blood glucose-137* urean-67* creat-2.4* na-144 k-4.9 cl-104 hco3-30 angap-15 04:55pm blood alt-30 ast-35 alkphos-115 amylase-82 totbili-0.4 04:55pm blood albumin-3.9 calcium-9.2 phos-3.7 mg-2.4 04:55pm blood %hba1c-6.3* chest x-ray: heart is mildly enlarged, pulmonary vasculature is mildly engorged, and there is no pulmonary edema or pleural effusion. four transvenous leads represent right atrial pacer, right ventricular pacer, left ventricular pacer and right ventricular pacer defibrillator leads each terminating in standard location, but continuity cannot be traced equivocally to the left axillary pacemaker, except for the right atrial lead because the lines are indistinguishable. carotid ultrasound: right ica with 60% to 69% stenosis. left ica with 40% to 59% stenosis. echocardiogram: the left atrium is elongated. the right atrium is moderately dilated. no atrial septal defect is seen by 2d or color doppler. the estimated right atrial pressure is 0-10mmhg. left ventricular wall thicknesses are normal. the left ventricular cavity is mildly dilated. there is mild regional left ventricular systolic dysfunction with basal inferior/infero-lateral hypokinesis. there is no ventricular septal defect. with mild global free wall hypokinesis. the aortic valve leaflets (3) are mildly thickened but aortic stenosis is not present. no aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. there is no mitral valve prolapse. an eccentric, posteriorly directed jet of at least moderate (2+) mitral regurgitation is seen (ischemic mr is suggested). the tricuspid valve leaflets are mildly thickened. there is moderate pulmonary artery systolic hypertension. there is no pericardial effusion. chest x-ray: 1. stable bilateral pleural effusions left greater than right. 2. new left infrahilar opacity may be secondary to underlying fluid less likely reflects underlying atelectasis and/or edema. edema and associated atelectasis cannot be entirely excluded. brief hospital course: mr. was admitted for heparinization and routine preoperative evaluation. carotid ultrasound was notable for mild to moderate disease of both internal carotid arteries(see result section). preoperative echocardiogram revealed 2+ mitral regurgitation and an lvef of 50-55%(see result section). surgery was initially delayed secondary to elevated prothrombin time. vitamin k was given with improvement in coagulation. on , dr. performed coronary artery bypass grafting along with mitral valve replacement and atrial septal defect closure. see operative note for additional surgical details. following the operation, he was brought to the cvicu for invasive monitoring. within 24 hours, he awoke neurologically intact and was extubated without incident. on postoperative day one, he transferred to the sdu for further care and recovery. he was restarted on warfarin and dosed for a goal inr between 2.0 - 3.0. he was transfused with prbc to maintain hematocrit near 30%. pacemaker interrogation showed complete heart block and he remained v-paced. over several days, he continued to make clinical improvements with diuresis. he was eventually cleared for discharge to rehab on postoperative day 5. medications on admission: amiodarone 200mg qd, norvasc 5mg qd, aspirin 81mg qd, calcium, combivent, digoxin .125mg qd, iron, flovent, folbic 2/2.5mg qd, humulin n, humulin r, lasix 80mg qd, lipitor 80mg qd, lisinopril 10mg qd, lopressor 50mg tid, omeprazole 40mg qd, coumadin (stopped prior to admission) discharge medications: 1. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). 2. pantoprazole 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po q24h (every 24 hours). 3. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). 4. atorvastatin 80 mg tablet sig: one (1) tablet po daily (daily). 5. fluticasone 110 mcg/actuation aerosol sig: two (2) puff inhalation (2 times a day). 6. ipratropium-albuterol 18-103 mcg/actuation aerosol sig: two (2) puff inhalation q6h (every 6 hours). 7. ferrous sulfate 325 mg (65 mg iron) tablet sig: one (1) tablet po daily (daily). 8. tamsulosin 0.4 mg capsule, sust. release 24 hr sig: one (1) capsule, sust. release 24 hr po hs (at bedtime). 9. amiodarone 200 mg tablet sig: one (1) tablet po daily (daily). 10. metoprolol tartrate 25 mg tablet sig: one (1) tablet po bid (2 times a day). 11. senna 8.6 mg tablet sig: one (1) tablet po bid (2 times a day). 12. oxycodone-acetaminophen 5-325 mg tablet sig: one (1) tablet po q4h (every 4 hours) as needed for pain. 13. furosemide 20 mg tablet sig: two (2) tablet po daily (daily). 14. insulin nph human recomb 100 unit/ml suspension sig: thirty (30) units subcutaneous once a day. 15. humalog 100 unit/ml solution sig: sliding scale units subcutaneous ac & hs: bs 150-200 = 4u 201-250 = 6u 251-300 = 8u 301-350 = 10 u. discharge disposition: extended care facility: convalescent discharge diagnosis: coronary artery disease s/p coronary artery bypass graft x 4 mitral regurgtation s/p mitral valve replacment atrial septal defect s/p closure atrial fibrillation pmh: s/p myocardial infarction w/ stenting/ptca , cardioversion , hyperlipidemia, hypertension, diabetes mellitus, congestive heart failure, chronic obstructive pulmonary disease, stroke , renal insufficiency, back pain, s/p icd/ppm placement, s/p lens implant ou , s/p bilaterala inguinal hernia repair, s/p polypectomy discharge condition: good discharge instructions: please shower daily including washing incisions, no baths or swimming monitor wounds for infection -
