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: no known allergies / adverse drug reactions attending: chief complaint: chest burning major surgical or invasive procedure: coronary artery bypass graft x 4 (left internal mammary artery to left anterior descending artery and saphenous vein grafts to diagonal and posterior descending arteries and left radial artery to obtuse marginal artery). 2. endoscopic harvesting of the long saphenous vein. 3. left radial artery harvesting. history of present illness: 46 year old male who has a strong family history of coronary artery disease and has had an abnormal stress test in the past. he had been noticing some mild left bicep discomfort early while exercising on a treadmill. he underwent a nuclear stress test which revealed a medium area of moderate stress induced myocardial ischemia in the distribution of the rca/pda coronary artery at a high cardiac workload. lvef was 60%. at that time after discussion with dr , he decided to wait a while before undergoing coronary angiography. more recently the patient has been experiencing some stress at work and decided he would like to proceed with coronary angiogram. he was found to have coronary artery disease upon cardiac catheterization and is now being referred to cardiac surgery. past medical history: wisdom teeth surgery s/p vasectomy social history: race:caucasian last dental exam:3-4 months lives with:wife and children contact: (wife) phone # occupation:information technology director for the city of cigarettes: smoked no yes other tobacco use:denies etoh: < 1 drink/week drinks/week >8 drinks/week illicit drug use:denies family history: premature coronary artery disease- brother with heart attack at age 36 and 42 and had bypass;

left internal mammary artery to left anterior descending artery and saphenous vein grafts to diagonal and posterior descending arteries and left radial artery to obtuse marginal artery. 2. endoscopic harvesting of the long saphenous vein. 3. left radial artery harvesting. his cardiopulmonary bypass time was 82 minutes with a crossclamp time of 71 minutes. he tolerated the operation well and post-operatively was transferred to the cvicu for invasive monitoring in stable condition. within several hours he awoke neurolgically intact and was extubated. he remained hemodynamically stable and on pod1 was started on bblockers, asa, statins and diuretics. additionally he was transferred to the stepdown floor for continued post-operative care. all tubes lines and drains were removed per cardiac surgery protocol. once on the floor he worked with nursing and physical therapy to increase his strength and endurance. he continued to progress in activity and on pod#4 was discharged home with visiting nurses. he is to follow up with dr in 1 month. medications on admission: atenolol 25 mg daily nitroglycerin dosage uncertain simvastatin 40 mg daily aspirin 81 mg daily omega 3 fish oil dosage uncertain discharge medications: 1. 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* 2. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 3. simvastatin 40 mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*2* 4. omega-3 fatty acids capsule sig: one (1) capsule po daily (daily). disp:*30 capsule(s)* refills:*2* 5. isosorbide mononitrate 30 mg tablet extended release 24 hr sig: one (1) tablet extended release 24 hr po daily (daily) for 3 months. disp:*30 tablet extended release 24 hr(s)* refills:*3* 6. metoprolol tartrate 25 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*2* 7. tramadol 50 mg tablet sig: one (1) tablet po q4h (every 4 hours) as needed for pain. disp:*50 tablet(s)* refills:*0* 8. lasix 20 mg tablet sig: one (1) tablet po once a day for 7 days. disp:*7 tablet(s)* refills:*0* 9. potassium chloride 10 meq tablet extended release sig: one (1) tablet extended release po once a day for 7 days. disp:*7 tablet extended release(s)* refills:*0* discharge disposition: home with service facility: americare at home inc discharge diagnosis: coronary artery disease s/p coronary artery bypass graft x4 past medical history: wisdom teeth surgery s/p vasectomy discharge condition: alert and oriented x3 nonfocal ambulating with steady gait incisional pain managed with dilaudid incisions: sternal - healing well, no erythema or drainage leg-left -healing well, no erythema or drainage. edema: 1+ l>r discharge instructions: please shower daily including washing incisions gently with mild soap, no baths or swimming until cleared by surgeon. look at your incisions daily for redness or drainage please no lotions, cream, powder, or ointments to incisions each morning you should weigh yourself and then in the evening take your temperature, these should be written down on the chart no driving for one month or while taking narcotics. driving will be discussed at follow up appointment with surgeon. no lifting more than 10 pounds for 10 weeks please call with any questions or concerns **please call cardiac surgery office with any questions or concerns . answering service will contact on call person during off hours** followup instructions: you are scheduled for the following appointments wound clinc at 10:15a surgeon dr on at 1:45p cardiologist: dr. at 5:40p office please call to schedule appointments with your primary care dr. in weeks **please call cardiac surgery office with any questions or concerns . answering service will contact on call person during off hours** md procedure: (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery diagnoses: coronary atherosclerosis of native coronary artery examination of participant in clinical trial
