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 the present illness: the patient is a 59-year-old man with cardiac risk factors of hypertension, tobacco use, positive family history, and ptca in the past who had two episodes of chest pain over the weekend; both happened while he was at rest and were relieved by sublingual nitroglycerin. he has been pain-free since that time. however, since he had a ptca of the left main in of last year, it was felt that he should be re-catheterized with the onset of this chest pain. past medical history: 1. hypertension. 2. cad. 3. hypercholesterolemia. 4. paroxysmal atrial fibrillation. allergies: the patient has no known drug allergies. medications prior to admission: 1. aspirin 325 once a day. 2. lopressor 25 twice a day. 3. lipitor 20 mg once a day. 4. wellbutrin 150 mg twice a day. 5. plavix 75 mg once a day. 6. coumadin 5 mg once a day. family history: both parents died in their 70s from an mi. he has one brother who has had a cabg in the past. social history: formerly worked laying carpets. he has been disabled since . positive tobacco use, currently one pack per day, previously two packs per day times 40 years. remote alcohol use. he has quit since . studies: as stated previously, the patient was admitted to to undergo cardiac catheterization. please see the catheterization report for full details. in summary, the cath showed left main with diffuse moderate in-stent restenosis up to 90%, lad was normal, left circumflex was normal, and rca was normal. he had no mitral regurgitation and mild global hypokinesis. following catheterization, ct surgery was consulted. the ekg at the time of catheterization was sinus brady at a rate of 54, intervals 0.18, 0.82, 0.40, with qs in iii and avf. the laboratory data revealed a white count of 9.4, hematocrit 44.9, platelets 354,000. sodium 139, potassium 4.6, chloride 103, c02 24, bun 17, creatinine 0.7, glucose 89, inr 1.4. physical examination: height 5' 4", weight 170 pounds. vital signs: heart rate 54, sinus rhythm, blood pressure 132/80, respiratory rate 20, 02 saturation 98% on room air. general: the patient was in no acute distress. heent: pupils were equally round and reactive to light with extraocular movements intact, anicteric, noninjected. op and mucous membranes were moist. there was no erythema or exudate. positive dental caries. neck: supple with no lymphadenopathy, no thyromegaly, no bruits. chest: clear to auscultation. coronary: regular rate and rhythm, s1, s2, with no murmurs, rubs, or gallops. abdomen: soft, nontender, nondistended, normoactive bowel sounds, no hepatosplenomegaly. extremities: warm and well perfused with no clubbing, cyanosis or edema. no varicosities. pulses: carotids 2+ bilaterally with no bruit. radial 2+ bilaterally. femoral 2+ bilaterally. dorsalis pedis and posterior tibial 1+ bilaterally. hospital course: the patient was seen by ct surgery and accepted for coronary artery bypass grafting. on , the patient was brought to the operating room where he underwent coronary artery bypass grafting times two. please see the or report for full details. in summary, the patient had a cabg times two with lima to lad and saphenous vein grafts to the om. 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 a mean arterial pressure of 80, cvp 13. he was a paced with a heart rate of 88. at the time of transfer, he had propofol at 20 micrograms/kilogram per minute and neo-synephrine at 0.3 micrograms/kilogram per minute. the patient did well in the immediate postoperative period. his anesthesia was reversed. he was weaned from sedation and then weaned from the ventilator, successfully extubated within several hours of arrival to the cardiothoracic intensive care unit. on postoperative day number one, the patient remained hemodynamically stable. his chest tubes were removed and he was transferred to the floor for continued postoperative care and cardiac rehabilitation. once on the floor, the patient was noted to be in a rapid atrial fibrillation with a heart rate up to 147. he was treated with iv lopressor followed by a bolus of amiodarone. the lopressor controlled his rate and eventually he converted to a normal sinus rhythm. he did, however, continue to have episodes of intermittent atrial fibrillation throughout his hospitalization and was subsequently anticoagulated. over the next several days, the patient remained hemodynamically stable. his activity level was increased with the assistance of physical therapy and the nursing staff. as stated previously, he was ultimately anticoagulated with heparin and coumadin. on postoperative day number five, it was felt that he was getting close to his goal inr and would be ready for discharge to home within the next day or two. discharge physical examination: at this time, the patient's physical examination is as follows: vital signs: temperature 98, heart rate 64, sinus rhythm, blood pressure 121/66, respiratory rate 18, 02 saturation 98% on room air. weight preoperatively 77 kilograms, at discharge 74.5 kilograms. the laboratories revealed a white count of 9.6, hematocrit 31.9, platelets 385,000. sodium 137, potassium 4.8, chloride 102, c02 20, bun 19, creatinine 0.9, glucose 110. the inr on is 1.3. discharge medications: 1. lasix 20 mg q.d. times seven days. 2. potassium chloride 20 meq q.d. times seven days. 3. metoprolol 50 mg b.i.d. 4. bupropion 75 mg q.d. 5. enteric coated aspirin 81 mg q.d. 6. coumadin over the past two days has been dosed with 5 mg, goal inr was 2.0. 7. amiodarone 400 mg b.i.d. times two weeks and then 400 mg q.d. times two weeks and then 200 mg q.d. p.r.n. medications: percocet 5/325 one to two tablets q. four hours p.r.n. condition at the time of discharge: stable. discharge diagnosis: 1. coronary artery disease, status post coronary artery bypass grafting times

fibrillation. follow-up: the patient is to follow-up with dr. for his coumadin dosing and follow-up with dr. in four to six weeks. anticipated date of discharge is or . , m.d. dictated by: medquist36
