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: burning in throat major surgical or invasive procedure: four vessel coronary artery bypass grafting utilizing left internal mammary to left anterior descending artery; vein grafts to ramus intermedius, obtuse marginal and right coronary artery. history of present illness: 81 y/o male experiencing burning in throat with activity. referred for ett. +ett and then referred for cardiac cath. cath revealed 3 vessel disease: rca 70-90%, lcx 70-75%, lad 80-90%, ef 50%. after cath at

09:40am blood alt-41* ast-36 alkphos-81 amylase-40 totbili-2.0* brief hospital course: patient was admitted and underwent routine preoperative evaluation. laboratory values were unremarkable while a carotid ultrasound found minimal disease of both internal carotid arteries. he was noted to have short runs of nsvt on telemetry but otherwise remained stable and pain free on medical therapy. on , dr. performed four vessel coronary artery bypass grafting. the operation was uneventful and he was brought to the csru in stable condition. within 24 hours, he awoke neurologically intact and was extubated. he was transfused with packed red blood cells to maintain hematocrit near 30%. on postoperative day one, he was noted to have an elevated lactate, amylase and lipase. an abdominal ultrasound was obtained and notable for cholelithiasis without evidence of cholecystitis. serial abdominal examinations remained benign. he maintained stable hemodynamics and weaned from inotropic support without difficulty. on postoperative day two, he transferred to the sdu. he went on to experience atrial fibrillation. beta blockade was resumed while amiodarone therapy was initiated. heparin was also initiated and stopped once inr became therapeutic under coumadin titration. additional units of packed red blood cells were transfused. k and mg levels were monitored closely and repleted per protocol. he was noted to have some erythema at his lle saphenectomy incision site on post-op day seven and keflex was initiated and will be continued for 1 week. pt made a steadily post-operative recovery, but was unable to achieve level 5 status and will be discharged to rehab facility for further physical therapy. pt. remained in atrial fibrillation at time of discharged and will be followed by rehab for coumadin dosing and inr checks. medications on admission: 1. atenolol 25mg qd 2. fosamax 60mg qwk 3. lescol 4. lovastatin 20mg qd 5. zoloft 50mg qd 6. levoxyl 50mg qd 7. mvi 8. xalatan qh
