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: coronary artery bypas graft x 3 (left internal mammary artery to left anterior descending, saphenous vein graft to obtuse marginal, saphenous vein graft to posterior descending artery) history of present illness: 79 year old with known coronary artery disease and prior myocardial infarction who presents with increased dyspnea on exertion over last year. recent stress test was positive and cardiac cath revealed severe three vessel coronary artery disease. past medical history: coronary artery disease, history of myocardial infarction hypertension hyperlipidemia chronic renal insufficiency reactive airway disease osteoarthritis carotid disease benign prosatic hypertrophy head injury secondary to motor vehicle accident social history: retired. 40 pack year smoking history. denies alcohol use. family history:

urean creat k 05:45am 31* 1.7* 4.9 echo: pre-bypass: 1. no mass/thrombus is seen in the left atrium or left atrial appendage. 2. no atrial septal defect is seen by 2d or color doppler. 3. there is mild regional anteroseptal, septal, inferoseptal, and apical wall hypokinesis, in the presence of global left ventricular hypokinesis (lvef = 40-45 %). 4. right ventricular chamber size and free wall motion are normal. 5. the diameters of aorta at the sinus, ascending and arch levels are normal. 6. there are simple atheroma in the ascending aorta. there are simple atheroma in the aortic arch. there are complex (>4mm) atheroma in the descending thoracic aorta. 7. the aortic valve leaflets (3) appear structurally normal with good leaflet excursion and no aortic regurgitation. there is no aortic valve stenosis. the mitral valve leaflets are mildly thickened. mild to moderate (+) mitral regurgitation is seen. post-bypass: 1. for the post-bypass study, the patient was receiving vasoactive infusions including phenylephrine. av pacing initially. 2. preserved biventricular systolic function from pre cpb. inferior hypokinesis. lvef is now 45%. 3. aortic contour is normal post decannulation. brief hospital course: mr. . was a same day admit after undergoing preoperative work-up prior to admission. on he was brought to the operating room where he underwent a coronary artery bypass graft x 3. 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. on post-operative day one he was transferred to the telemetry floor for further care. he had a short run of atrial fibrillation which converted to sinus rhythm with beta blockers. chest tubes and epicardial pacing wires were removed per protocol. he continued to slowly improve and worked with physical therapy for strength and mobility. mr. . did c/o difficulty swallowing- a speech and swallow consult and video swallow was done and no abnormality was detected. he had no further complaints of swallowing difficulty. on post-operative day #4 he was discharged to home with vna. medications on admission: simvastatin 40mg daily, benicar 20mg daily, aspirin 81mg daily, metoprolol 25mg daily, avodart 0.5mg daily, advair 250/50mg , methotrexate 10
