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: asymptomatic major surgical or invasive procedure: coronary artery bypass graft x 4 (lima->lad/svg->diag/om/pda) history of present illness: 67 y/o male with diabetes, hypertension, and peripheral arterial disease. he was asymptomatic but had positive stress test and was referred for cardiac cath. cath revealed severe three vessel disease and was referred for surgery revascularization. past medical history: diabetes mellitus, hypertension, nephropathy, peripheral arterial disease rle, lle compound fx as child, s/p (l) cea'/ s/p fem. bypass, s/p tonsillectomy social history: social history is significant for the absence of current tobacco use, quit 2 months ago, 2ppd x 50 yrs. there is no history of alcohol abuse family history: there is a family history of premature coronary artery disease, brother had in 50s and died at 51 from "heart failure." physical exam: vs: 66 14

mae, non-focal pertinent results: echo: pre-bypass: 1. the left atrium and right atrium are normal in cavity size. no atrial septal defect is seen by 2d or color doppler. 2. left ventricular wall thicknesses are normal. the left ventricular cavity size is normal. overall left ventricular systolic function is normal (lvef>55%). 3. right ventricular chamber size and free wall motion are normal. 4. the ascending aorta is mildly dilated. there are simple atheroma in the aortic arch. the descending thoracic aorta is mildly dilated. there are complex (>4mm) atheroma in the descending thoracic aorta. 5. the aortic valve leaflets (3) appear structurally normal with good leaflet excursion and no aortic regurgitation. 6. the mitral valve leaflets are mildly thickened. trivial mitral regurgitation is seen. dr. was notified in person of the results. post-bypass: 1. regional and global left ventricular systolic function are normal. 2. right ventricular systolic function is normal. 3. aortic contours are intact post decannulation. 11:35am blood wbc-16.1*# rbc-3.51* hgb-10.9* hct-31.8* mcv-91 mch-31.1 mchc-34.3 rdw-13.8 plt ct-227 05:30am blood wbc-12.3* rbc-2.87* hgb-8.9*

brought directly to the operating room where he underwent a coronary artery bypass graft x 4. 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. he required aggressive chest pt while in icu. on post-op day two his chest tubes were removed and he was started on beta blockers and diuretics. he was gently diuresed towards his pre-op weight. epicardial pacing wires were removed on post-op day three. on post-op day four he was transferred to the telemetry floor for further care. his creatinine trended up but stabilized around 2.3 at time of discharge. over the next several days he slowly recovered while working with physical therapy for strength and mobility. on post-op day seven he appeared ready for discharge home with vna services and the appropriate follow-up appointments. medications on admission:
