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: celebrex / aleve attending: chief complaint: dizzy and diaphoretic with ekg changes major surgical or invasive procedure: coronary artery bypass graft x4 (left internal mammary artery > left anterior descending, saphenous vein graft > diagonal, saphenous vein graft > ramus, saphenous vein graft > obtuse marginal) and maze, resection of left atrial appendage history of present illness: 73 year old man has a history of lone atrial fibrillation was admitted to on with a recurrence of atrial fibrillation. he had been exercising at the gym when he suddenly felt dizzy and diaphoretic. he noted his heart rate at 140-160 bpm. the episode lasted around an hour. ems was activated and an ekg by emt's was reported to show st depression in v3 through v6 with a heart rate of 162 bpm. he spontaneously converted to sinus rhythm by the time he arrived to the emergency room. troponin was indeterminate at 0.08. stress echo was completed during the admission. this was negative for chest pain. echo imaging revealed mild hypokinesis of the mid and apical septal segments with exercise. in terms of symptoms, he report feeling very well without chest discomfort, shortness of breath, fatigue or change in his activity tolerance. he was referred for left heart catheterization to further evaluate. he was found to have coronary artery disease and is now being referred to cardiac surgery for revascularization. past medical history: paroxysmal atrial fibrillation mild aortic insufficiency vitamin d deficiency erectile dysfunction childhood asthma gerd osteopenia stable lung nodule pseudogout s/p appendectomy s/p resection of lipoma at age 12 s/p tonsillectomy s/p resection of colon polyps social history: lives with:wife occupation:retired tobacco: quit in etoh: 1-2 drinks/day family history: mother with cabg in her 70's physical exam: pulse:48 resp:13 o2 sat:97/ra b/p right:130/68 left: 134/72 height:5'7" weight:183 lbs general: skin: dry intact 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 varicosities: none neuro: grossly intact pulses: femoral right: left: dp right:2+ left:2+ pt : left: radial right: left: carotid bruit-none right:2+ left:2+ pertinent results: 12:05pm blood wbc-11.5*# rbc-3.24*# hgb-9.8*# hct-28.7* mcv-89 mch-30.4 mchc-34.3 rdw-12.9 plt ct-191 12:05pm blood plt ct-191 12:05pm blood pt-15.8* ptt-26.5 inr(pt)-1.4* 01:40pm blood urean-16 creat-0.8 na-143 k-4.3 cl-114* hco3-23 angap-10 01:40pm blood mg-2.0 echocardiographic measurements results measurements normal range left ventricle -
