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. hypertension. 2. hypercholesterolemia. 3. depression. 4. gastroesophageal reflux disease. 5. arthritis. catheterization results showed the lad 40% occluded, left circumflex 80% occluded, rca 100% occluded. the ejection fraction was estimated to be 45%. medications: (home). 1. lopressor 75 mg p.o.b.i.d. 2. captopril 12.5 p.o. t.i.d. 3. paxil 10 mg p.o.q.d. 4. tagamet. hospital course: the patient was taken by dr. to the or on for cabg times, lima to lad, svg to rca and svg to om. during the postoperative course, the patient did well. the chest tube was discontinued. the patient was able to be extubated without any instance. however, the course is complicated by postoperative atrial fibrillation on postoperative day #3. the patient's atrial fibrillation was able to be controlled with 30 mg iv lopressor. the patient was subsequently started on amiodarone. upon discharge, the patient's vitals were stable. rhythm was in sinus. the discharge physical examination revealed the chest clear to auscultation, no wheezing. heart revealed regular rate and rhythm, normal sinus. incision was clean, dry, and intact, no drainage, no pus, sternum stable. discharge medications: 1. lopressor 25 mg p.o.b.i.d. 2. aspirin 81 mg p.o.q.d. 3. lasix 20 mg p.o.b.i.d. times five days. 4. -ciel 20 meq p.o. b.i.d. times five days. 5. paxil 10 mg p.o.q.d. 6. amiodarone 400 mg p.o.t.i.d. times one week and then 400 mg p.o. b.i.d. times one week, then 400 mg p.o.q.d. follow-up care: the patient was told to followup with dr. in three to four weeks. also, the patient was told to followup with her primary care physician, . . dr., w. 02-229 dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery coronary arteriography using two catheters (aorto)coronary bypass of two coronary arteries angiocardiography of left heart structures injection or infusion of platelet inhibitor left heart cardiac catheterization monitoring of cardiac output by other technique diagnoses: pure hypercholesterolemia mitral valve disorders unspecified essential hypertension cardiac complications, not elsewhere classified atrial fibrillation other and unspecified angina pectoris acute myocardial infarction of unspecified site, initial episode of care arthropathy, unspecified, site unspecified acute conjunctivitis, unspecified 

Answer: The patient is high likely exposed to
