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, chest pain major surgical or invasive procedure: cabg x 3 (lima->lad, svg->om1, om2), avr (25mm pericardial valve) history of present illness: delightful 72 year old gentlema with h/o aortic insufficiency and dilated ascending aorta who was being evaluated for a total knee replacement. he has noted worsening dyspnea and angina with activity. in work-up for his knee surgery, a stress test was performed which noted early onset angina and inferolateral ischemia. a cardiac catheterization was performed which revealed moderate coronary artery disease, severe aortic insufficiency and a dilated ascending aorta. he now presents for surgical management. past medical history: hyperlipidemia htn hypothyroid arthritis bph social history: retired employee. never smoked and does not drink alcohol. lives with his wife in . family history: noncontributory physical exam: 74 sr 12 122/68 126/68 gen: wdwn in nad skin: warm, no c/c/e, well healed ventral hernia incision. heent: ncat, perrl, eomi, anicteric sclera, op benign neck: supple, from, 2+ carotids without bruits. lungs: clear heart: rrr, ii/vi late systolic and i/vi diastolic murmur. abd: benign ext: warm, well perfused, no edema neuro: nonfocal pertinent results: echo prebypass: 1. no thrombus is seen in the left atrial appendage. no atrial septal defect is seen by 2d or color doppler. 2. 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 moderately dilated. there are simple atheroma in the ascending aorta. the aortic arch is mildly dilated. the descending thoracic aorta is mildly dilated. there are simple atheroma in the descending thoracic aorta. 5. there is no valvular aortic stenosis. the increased transaortic gradient is likely related to aortic regurgitation. moderate to severe (3+) aortic regurgitation is seen. 6. the mitral valve leaflets are mildly thickened. trivial mitral regurgitation is seen. postbypass: on phenylephrine infusion. well-seated bioprosthetic valve in the aortic position with trivial central ai and washing jets. preserved biventricular systolic funbction. normal aortic contour post decannulation. 06:10am blood wbc-9.6 rbc-3.40* hgb-10.8*

taken to the operating room where he underwent coronary artery bypass grafting to three vessels and an aortic valve replacement with a 25mm pericardial valve. please see operative note for details. postoperatively he was taken to the cardiac surgical intensive care unit for monitoring. he was noted to have a high output from his drains and was thus returned to the operating room where he was re-explored for bleeding. hemostasis was acheived and he was taken back to the intensive care unit for monitoring. by postoperative day one, mr. had awoke neurologically intact and was extubated. beta blockade, aspirin and a statin were resumed. he was then transferred to the step down unit for further recovery. he was gently diuresed towards his preoperative weight. the physical therapy service was consulted for assistance with his postoperative strength and mobility. on he was found to have a distended abdomen, kub showed colonic ileus. he was seen by general surgery who felt that he had a resolved ileus. he tolerated an advancing diet, and continued to pass gas and have bowel movements. he was ready for discharge on pod #6. medications on admission: synthroid 125mcg daily aspirin 81mg
