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: past medical history: 1. hypercholesterolemia. 2. hernia operation at age 17. 3. denied any hypertension, diabetes, strokes, or previous heart attacks. admission medications: 1. lipitor 10 mg once a day. 2. aspirin 325 mg once a day. allergies: the patient has no known drug allergies. social history: he smokes two packs per day for 50 years. he drinks ethanol socially. he sells shoes. family history: his father had a heart attack at age 57. his brother had a heart attack at age 55. review of systems: no fevers, chills, no cough, no shortness of breath, no diarrhea, no dysuria. physical examination on admission: general: he was in no apparent distress, comfortable, afebrile. vital signs: pulse 71, blood pressure 156/34, respirations 20, 96% on room air. head and neck: normocephalic, atraumatic. eomi. neck: supple. no lymphadenopathy. heart: regular rate and rhythm. no murmurs, rubs, or gallops. lungs: clear to auscultation bilaterally. no crackles or wheezes. abdomen: soft, nontender, nondistended. extremities: no clubbing, cyanosis or edema. laboratory/radiologic data: on admission, wbc 10.7, hematocrit 45.4, platelets 264,000. pt 12.6, ptt 28.3, inr 1.0. sodium 141, potassium 4.3, chloride 100, bicarbonate 32, bun 15, creatinine 1.1, sugar 166. ck 122, ck mb 5.9, troponin 2.2, all of which were elevated. chest x-ray showed no acute cardiopulmonary process. the ekg revealed a normal sinus rhythm with t wave inversions in v1-v6 and iii. hospital course: this patient was admitted to c medicine and cardiac catheterization was performed. the cardiac catheterization showed three vessel disease with left anterior descending artery stenosis of 90%, right coronary artery stenosis of 80%, om2 artery stenosed 90%, and the left circumflex was stenosed 70%. at this time, cardiothoracic surgery was consulted and it was determined that the patient was in need of a coronary artery bypass graft surgery. over the next few days, he was consented and preopped. his preoperative echocardiogram revealed left ventricular hypertrophy with normal systolic function, ef greater than 55%. once consented, the patient was taken to the operating room on . for the first six days, while he was being preopped for his cabg, he was monitored on telemetry and observed closely. on , the patient was taken to the operating room for cabg. please refer to the previously dictated operative note by dr. . briefly, four grafts were made, left internal mammary artery to the lad and three saphenous vein grafts, one to the pda, one to the om, one to the diagonal arteries. he underwent cardiopulmonary bypass for 155 minutes and the aorta was cross-clamped for 120 minutes. he tolerated the procedure well and was transferred to the crsu in good condition on levophed, nitroglycerin, and propofol drips. the night of surgery, he did very well and was extubated without complication. on postoperative day number one, the patient was noted to have several ekg changes including a new right bundle branch block. cardiology consult was obtained and the cardiology team did not recommend any changes in management. in addition, in the icu, the patient's course was also noted for a brief amount of atrial fibrillation which was treated initially with heparin and amiodarone. the patient's atrial fibrillation converted back to normal sinus rhythm on the amiodarone and the patient was transferred to the floor on postoperative day number four. on postoperative day number four, , the patient was transferred back to the floor. the patient's floor issues mainly revolved around diet. the patient soon was able to tolerate a regular cardiac healthy diet and prior to discharge was able to sustain his nutritional requirements. fluids, electrolytes, and nutrition: the patient was diuresed with lasix and on the date of discharge, the patient was close to baseline weight of only 1.9 kilograms over his baseline weight of 91 kilograms. the patient was evaluated on the floor by the physical therapist who cleared him on . prior to his discharge, the patient was noted to not really be having any trouble with atrial fibrillation while on his amiodarone so his heparin and coumadin were stopped prior to discharge and he will not be sent home on this medication. a chest x-ray prior to discharge revealed a small left-sided effusion but otherwise very normal well aerated lungs. on , the patient is being discharged home in good condition. final diagnosis: 1. three vessel coronary artery disease. 2. unstable angina. 3. acute myocardial infarction. 4. status post coronary artery bypass graft times four. 5. postoperative atrial fibrillation. 6. pleural effusion. 7. postoperative electrocardiogram changes. discharge medications: 1. aspirin 81 mg once a day. 2. metoprolol 25 mg p.o. twice a day. 3. amiodarone 200 mg p.o. b.i.d. for one week and then 200 mg p.o. q.d. until his follow-up appointment with dr. . 4. lipitor 10 mg p.o. q.d. 5. percocet one to two tablets p.o. q. four to six hours as needed for pain. 6. colace 100 mg p.o. b.i.d. as needed for constipation. 7. lasix 20 mg p.o. b.i.d. 8. potassium 10 mg p.o. b.i.d. discharge instructions: the patient was recommended to continue his cardiac healthy diet, no driving, no bathing, no lifting objects heavier than a gallon of milk. follow-up: he is recommended to follow-up with his primary care physician in one week, his cardiologist in two to three weeks, and dr. in one month. , m.d. dictated by: medquist36 procedure: (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery coronary arteriography using two catheters angiocardiography of left heart structures injection or infusion of platelet inhibitor left heart cardiac catheterization diagnostic ultrasound of heart aortography diagnoses: subendocardial infarction, initial episode of care coronary atherosclerosis of native coronary artery tobacco use disorder unspecified pleural effusion atrial fibrillation other and unspecified hyperlipidemia right bundle branch block family history of ischemic heart disease 

Answer: The patient is high likely exposed to
