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: coronary artery bypass graft x 5 (left internal mammary artery to left anterior descending, saphenous vein graft to diagonal, saphenous vein graft to obtuse marginal, saphenous vein graft to posterior descending artery to posterior lateral branch) cardiac cath history of present illness: this active 53 year old gentleman has a history of chest pain for the past year which he describes as occurring intermittently with exertion such as running with his dog or playing volleyball. he had a stress test done last year, in which demonstrated a mild apical reperfusion defect. he was started on a medication regimen and continues to have symptoms. he denies symptoms occurring at rest. he was seen by dr. earlier this month. the stress test was reviewed by dr. and given the patient??????s continued symptoms, he has been referred for outpatient cardiac catheterization. past medical history: hypertension hyperlipidemia hepatitis c diagnosed in status post 20 month interferon therapy social history: married, 2 children (35, 28) -tobacco history: 30 pack years quit 4-5 years ago -etoh: 1-2 beers/day -illicit drugs: denies family history: notable for a brother with heart disease. no family history of early mi, arrhythmia, cardiomyopathies, or sudden cardiac death; otherwise non-contributory. physical exam: vitals: 56 18 161/107 5'5" 165lbs general: no acute distress, alert and oriented x 3 skin: unremarkable heent: unremarkable neck: supple, full range of motion chest: clear to auscultation bilaterally heart: regular rate and rhythm with no murmur abd: soft, non-tender, non-distended, +bowel sounds ext: warm, well-perfused, -edema neuro: grossly intact pertinent results: cardiac cath: 1. coronary angiography of this right dominant system revealed three vessel coronary artery disease. the lmca had a long 90% stenosis. the lad had minimal disease. the lcx was a small vessel without significant stenoses. the proximal rca had an ostial 60% lesion with catheter damping and partial spasm. the distal rca had a 70% lesion before the crux. 2. resting hemodynamics revealed mildly elevated systemic arterial blood pressure (sbp 140 mm hg). 3. left ventriculography was deferred. carotid u/s: right ica stenosis <40%. left ica stenosis <40%. echo: pre-bypass: 1. no atrial septal defect is seen by 2d or color doppler. 2. left ventricular wall thickness, cavity size, and global systolic function are normal (lvef>55%). 3. right ventricular chamber size and free wall motion are normal. 4. there are simple atheroma in the aortic arch. there are simple atheroma in the descending thoracic aorta. 5. there are three aortic valve leaflets. there is no aortic valve stenosis. no aortic regurgitation is seen. 6. physiologic mitral regurgitation is seen (within normal limits). 7. there is a small pericardial effusion. dr. was notified in person of the results. post-bypass: for the post-bypass study, the patient was receiving vasoactive infusions including phenylephrine and is in sinus rhythm 1. biventricular function is normal 2.aorta is intact post decannulation 3. other findings are unchanged 07:10am blood wbc-12.3* rbc-2.76* hgb-8.5* hct-24.5* mcv-89 mch-30.7 mchc-34.5 rdw-13.5 plt

history of present illness, mr. cardiac cath on which revealed left main and severe three vessel disease. due to the severity of his disease, he was admitted following his cath and awaited surgical intervention. prior to surgery he was medically managed and underwent a comprehensive work-up. on he was brought to the operating room where he underwent a coronary artery bypass graft x 5. please see operative report for surgical details. following surgery he was transferred to the cvicu for invasive monitoring in stable condition. within 24 hours he was weaned from sedation, awoke neurologically intact and extubated. on post-operative day one he appeared to be doing well and was transferred to the telemetry floor for further care. chest tubes and epicardial pacing wires were removed per protocol. he was transferred to the step down unit on post-operative day 2 and physical therapy was consulted to work on strength and balance. he continued to progress well and was ready for discharge to home on post-operative day 5. medications on admission: hctz 12.5mg daily, lisinopril 10mg daily, atenolol 25mg daily, simvastatin 20mg daily, wellbutrin 150mg daily, aspirin 81mg daily discharge
