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: codeine / cipro / lactose attending: chief complaint: dyspnea on exertion major surgical or invasive procedure: : coronary artery bypass grafting x3 with left internal mammary artery to left anterior descending coronary; reverse saphenous vein single graft from aorta to the 1st obtuse marginal coronary; reverse saphenous vein single graft from aorta to posterior descending coronary artery. left anterior descending coronary artery endarterectomy and vein patch angioplasty. replacement of ascending aorta with a 28-mm dacron tube graft. history of present illness: 65 yo male with chronic atrial fibrillation with new onset dyspnea on exertion. recent stress testing showed mild anteroseptal ischemia. subsequent cardiac catheterization revealed multivessel coronary artery disease. he was referred for surgical revascularization. he continued to experience dyspnea on exertion but remains very active at home. he performs routine adl without difficulty. he denies chest pain, orthopnea, pnd, pedal edema and palpitations. of note, patient has never on warfarin anticoagulation for chronic atrial fibrillation. he has been maintained on aspirin only and has declined/refused warfarin. past medical history: - hypertension - diabetes mellitus type ii - chronic atrial fibrillation(since teenage years) - right leg/groin shotgun injury, now with prosthetic right leg - history of mrsa(right thigh/stump ulcer) - history of gout - "blood antigens" from history of multiple blood transfusions related to his shot gun injury - obesity past surgical history: - right femoral artery/vein repair with grafting secondary to shot gun injury complicated by recurrent cellulitis eventually requiring right leg above knee amputation - hernia repair - tonsillectomy - right eyelid - basal cell carcinoma social history: lives: alone occupation: disabled cigarettes: 30pyh, quit over 20 years ago etoh: social, no history of abuse illicit drug use: denies family history: sister mi at age 47 physical exam: pulse: 68-82 resp: 16 o2 sat: 97% room air b/p right: 151/105 left: 148/93 height: 72inches weight: 290 lbs general: obese male in no acute distress. pleasant, alert and oriented. skin: dry intact - multiple scars/incisions right groin and proximal thigh - healed with no evidence of cellulitis heent: perrla eomi neck: supple full rom chest: lungs clear bilaterally heart: rrr irregular murmur abdomen: soft non-distended non-tender bowel sounds + extremities: warm , well-perfused edema: trace varicosities: left gsv appears suitable. right thigh gsv not assessed secondary to prosthesis neuro: grossly intact pulses: femoral right: - left: 1+ dp right: 1+ left: 1+ pt : 1+ left: 1+ radial right: 2+ left: 2+ carotid bruit right: none left: none pertinent results: tte: pre bypass the left atrium is dilated. no mass/thrombus is seen in the left atrium or left atrial appendage. mild spontaneous echo contrast is present in the left atrial appendage. the right atrium is dilated. no atrial septal defect is seen by 2d or color doppler. there is an inferobasal left ventricular aneurysm. overall left ventricular systolic function is normal (lvef>55%). the right ventricle displays normal free wall contractility. the ascending aorta is mildly to moderately dilated. there are simple atheroma in the aortic arch. the descending thoracic aorta is mildly dilated. there are simple atheroma in the descending thoracic aorta. 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. mild (1+) mitral regurgitation is seen. there is a trivial/physiologic pericardial effusion. post bypass the patient is atrially paced. there is normal right ventricular systolic function. the left ventricle displays overall normal systolic function with the exception of the inferobasal aneurysm. the mitral regurgitation is slightly worsened but remains mild. the ascending aortic graft is only very poorly seen. the portions of the ascending, arch, and descending thoracic aorta that are seen are free of dissection. cxr: there is dense retrocardiac opacity consistent with combination of volume loss/infiltrate/effusion. the extreme left cp angle is off the film. right ij line tip is in the svc. increased opacity at the right base suggesting an area of volume loss/infiltrate in this region. this is new compared to the prior study. sternal wires and mediastinal clips are again seen. 05:53pm blood wbc-15.4*# rbc-3.85*

course: the patient was admitted to the hospital and brought to the operating room on where the patient underwent coronary artery bypass grafting x3 with left internal mammary artery to left anterior descending coronary; reverse saphenous vein single graft from aorta to the 1st obtuse marginal coronary; reverse saphenous vein single graft from aorta to posterior descending coronary artery, left anterior descending coronary artery endarterectomy and vein patch angioplasty and replacement of ascending aorta with a 28-mm dacron tube graft. please see operative note for surgical details. overall the patient tolerated the procedure well and post-operatively was transferred to the cvicu in stable condition for recovery and invasive monitoring. pod 1 found the patient extubated, alert and oriented and breathing comfortably. the patient was neurologically intact and hemodynamically stable on no inotropic or vasopressor support. beta blocker was initiated and the patient was gently diuresed toward the preoperative weight. the patient was transferred to the telemetry floor for further recovery. chest tubes and pacing wires were discontinued without complication. the patient was evaluated by the physical therapy service for assistance with strength and mobility. additionally, occupational therapy was consulted given the patient's aka and dependence on prosthesis. he does have long history of atrial fibrillation and remained in af post-op. as in the past, he declined/refused warfarin and was continued on aspirin. in addition, plavix was started for the lad endarterectomy and vein patch angioplasty by the time of discharge on pod 4 the patient was ambulating freely, the wound was healing and pain was controlled with oral analgesics. the patient was discharged to rehab ( in , nh) in good condition with appropriate follow up instructions. medications on admission: allopurinol 300 mg tablet once a day digoxin 125 mcg tablet once a day furosemide 40 mg tablet once a
