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: chest pain major surgical or invasive procedure: four vessel coronary artery bypass grafting(lima to lad, svg to om1, svg to om2, svg to pda) history of present illness: this is a 58 year old male who was recently admitted to with substernal exertional chest pressure. he ruled out for myocardial infarction. stress test on was notable for inferior st changes while nuclear imaging revealed a mild to moderate reversible inferior defect with an ejection fraction of 55%. patient was subsequently transferred to the for further evaluation and treatment. past medical history: hypercholesterolemia history of alcohol abuse bilateral knee surgery history of vertigo social history: admits to drinking 8-12 beers per day. he denies tobacco. he is married. he works in construction. family history: mother had mi at age 69. physical exam: vitals: 166/92, 69, 12 general: wdwn male in no acute distress heent: oropharynx benign, eomi neck: supple, no jvd lungs: cta bilaterally heart: regular rate and rhythm abdomen: soft, nontender with normoactive bowel sounds ext: warm, no edema pulses: 2+ distally neuro: alert and oriented, cn 2- 12 grossly intact, no focal deficits noted pertinent results: 02:48pm blood wbc-7.3 rbc-4.43* hgb-14.5 hct-40.9 mcv-92 mch-32.8* mchc-35.5* rdw-12.7 plt ct-287 09:05am blood inr(pt)-1.1 02:48pm blood glucose-117* urean-14 creat-0.8 na-138 k-4.0 cl-101 hco3-27 angap-14 02:48pm blood alt-34 ast-24 alkphos-63 totbili-0.7 02:48pm blood %hba1c-6.1* cardiac cath: 1. coronary angiography of this right dominant system revealed 3 vessel coronary artery disease. the lmca was a short vessel with distal narrowing. the lad had a 50% ostial stenosis. the lcx had an 80% ostial stenosis with a 50% stenosis of om2. the rca had serial 80% stenoses in its mid and distal portions. echocardiogram: the left atrium is normal in size. left ventricular wall thickness, cavity size and regional/global systolic function are normal (lvef 70%) right ventricular chamber size and free wall motion are normal. the aortic valve leaflets (3) appear structurally normal with good leaflet excursion and no aortic regurgitation. the mitral valve appears structurally normal with trivial mitral regurgitation. there is no mitral valve prolapse. there is no pericardial effusion. chest x-ray: in comparison with the study of , the patient has taken a much better inspiration. the left chest tube has been removed and there is no evidence of pneumothorax. the endotracheal tube, right ij catheter, and nasogastric tube both have been removed. some residual atelectatic changes are seen at the bases. brief hospital course: mr. was admitted under cardiology and underwent cardiac catheterization which revealed severe three vessel coronary artery disease - please see result section. cardiac surgery was therefore consulted and further evaluation was performed. echocardiogram showed normal left ventricular function and normal aortic and mitral valves - please see result section. his preoperative course was otherwise unremarkable and he was cleared for surgery. he remained pain free on medical therapy. on , dr. performed coronary artery bypass grafting surgery. see separate dictated operative note for surgical details. following the operation, he was brought to the cvicu for invasive monitoring. within 24 hours, he awoke neurologically intact and was extubated without incident. his cvicu course was uneventful and he transferred to the sdu on postoperative day one. chest tubes and pacing wires removed without incident.made good progress and cleared for discharge to home on pod #4. pt. is to make all follow-up appts. as per discharge instructions. medications on admission: no meds at home. hospital started lopressor 12.5 mg , nitropaste, ativan prn discharge medications: 1. metoprolol tartrate 25 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*2* 2. furosemide 20 mg tablet sig: one (1) tablet po q12h (every 12 hours) for 7 days. disp:*14 tablet(s)* refills:*0* 3. potassium chloride 10 meq capsule, sustained release sig: two (2) capsule, sustained release po q12h (every 12 hours) for 7 days. disp:*28 capsule, sustained release(s)* refills:*0* 4. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 5. ranitidine hcl 150 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*2* 6. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). disp:*30 tablet, delayed release (e.c.)(s)* refills:*2* 7. oxycodone-acetaminophen 5-325 mg tablet sig: one (1) tablet po q4h (every 4 hours) as needed for pain. disp:*50 tablet(s)* refills:*0* 8. hexavitamin tablet sig: one (1) cap po daily (daily). disp:*30 cap(s)* refills:*2* 9. thiamine hcl 100 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 10. folic acid 1 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 11. atorvastatin 20 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* discharge disposition: home with service facility: vna discharge diagnosis: coronary artery disease -
