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: history of present illness: mr. is an 81-year-old man with a history of atrial fibrillation, congestive heart failure, hypercholesterolemia and a recent episode of chest pain in with an unrevealing workup who is transferred from the hospital after presenting to the emergency department with chest pain unrelieved by nitroglycerin. he states that the night prior to his admission he awoke with right wrist pain that became diffuse chest pain. he took one of his wife's nitroglycerin pills and it somewhat resolved the chest pain but never fully resolved it. it recurred with diaphoresis and was again relieved by nitroglycerin after the third episode he went to the emergency room. at that point his pain was resolved without intervention and he has had no pain since admission to the emergency room. during his chest pain experienced in it was accompanied with shaking, at that time he ruled out for an myocardial infarction. the workup was done in st. . he came back to the states and was evaluated by dr. who treated him for history of valvular dysfunction with lasix and aldactone. past medical history: significant for chronic atrial fibrillation, cll diagnosed 16 years ago with no treatment with the exception of epogen. congestive heart failure. hypercholesterolemia and sick sinus syndrome. status post permanent pacemaker placement. medications: 1. lasix 20 mg q day. 2. toprol xl 25 mg q day. 3. protonix 40 mg q day. 4. hytrin no dose provided. 5. lipitor no dose provided. 6. coumadin 4 mg monday, wednesday, friday, 3.5 mg sunday, tuesday, thursday,

pack years. stopped 40 years ago. denies alcohol use. denies drug use. distant history of asbestos exposure. laboratory findings: white count 8.8, hematocrit 32.9, platelets 60. sodium 143, potassium 3.7, chloride 103, co2 23, bun 24, creatinine 1.2. glucose 95. pt 14, ptt 75, inr 1.7. ck from hospital 147 with an mb of 8.3 and troponin of 2.1. an echo done showed markedly dilated ra and la, dilated lvc and ef of 50% , 2% mr and 3 tr. the patient was admitted to the cardiology service and brought to cardiac cath lab where his catheterization showed left main with an 80% lesion, lad with an 80% lesion, circumflex with an 80% lesion. om2 with an 80% lesion, rca with no significant disease. an intra aortic balloon pump was also placed at that time and the patient was transferred to ccu pain free at the time of transfer. he was seen by ct surgery, was accepted for coronary artery bypass grafting following a consultation from the hematology service. on the patient was brought to the operating room. please see the o.r. report for full details. in summary he had coronary artery bypass grafting times two with a left internal mammary artery to the left anterior descending coronary artery, saphenous vein graft to obtuse marginal #1 and saphenous vein graft to obtuse marginal #2 as well as a pfo closure and a tricuspid valve repair with a #30 mm ring. his bypass time was 129 minutes with a cross clamp time of 96 minutes. he tolerated the operation well and was transferred from the operating room to the cardiothoracic intensive care unit. at the time of transfer the patient had intra-aortic balloon pump at 1 to 1. levophed at 0.5 mcs per kg per minute. epinephrine at 0.03 mg per kg per minute. milrinone at 0.5 mcs per kg per minute and propofol at 20 mcs per kg per minute. he was a paced at a rate of 86 beats per minute with a mean arterial pressure of 75 and a central venous pressure of 17. the patient did well in the immediate postoperative period. following his arrival in the cardiothoracic intensive care unit the electrophysiology service was called to interrogate his pacemaker. at that time his vvi pacemaker was turned up to a rate of 80 beats per minute. the patient's anesthesia was reversed, he was weaned from the ventilator and successfully extubated. he remained hemodynamically stable throughout the remainder of his operative day. on postop day one, the patient's epinephrine infusion was discontinued, his balloon pump was weaned and ultimately removed and his milrinone was also weaned. he did however require neo-synephrine infusion to maintain an adequate blood pressure. on postop day two, the patient continued to do well, he was hemodynamically stable. his milrinone was discontinued, his neo-synephrine was weaned to off. his chest tubes were removed. he remained in the cardiothoracic intensive care unit for continuing hemodynamic and pulmonary support. on postop day three the patient's temporary pacing wires were removed. he was restarted on his preoperative coumadin and if a bed had been available he would have been transferred to the floor. on postop day four the patient continued to progress and he was transferred to the floor for continuing postoperative care and cardiac rehabilitation. over the next several days the patient's activity level was increased with the insistence of the nursing staff and physical therapy. he had an uneventful hospital course. on postop day five the patient satisfactorily completed all the activity requirements of ct surgery service for discharge and it was felt that he would be able to be discharged the following morning. at this time the patient's physical examination is as follows. vital signs: temperature 98.1, heart rate 80, v- paced. blood pressure 94/48, respiratory rate 18, o2 sat 95% on room air. weight 73.2 kilos, at preop 72 kilos laboratory findings: white count 13.7, hematocrit 33.1, platelets 104, prothrombin time 14.4, inr 1.4. sodium
