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 present illness: this is a 64 year old patient of dr. who has had a history of coronary artery disease, diabetes with exertional angina who underwent a cardiac catheterization due to positive stress test in . at the time, the patient had an ejection fraction of 7% with anterolateral hypokinesis, anterior apical hyperkinesis, 60% pda stenosis, 80% left anterior descending stenosis and 40% circumflex stenosis with mild diastolic dysfunction. the patient eventually had a percutaneous transluminal coronary angioplasty of the mid left anterior descending times two in and was subsequently medically managed. an exercise tolerance test performed in was positive with a mild reversible defect of the inferior and lateral walls with mild global hypokinesis. since , the patient has been complaining of progressive increase in his angina which occurs when he walks after eating. he denies any angina with rest, nocturnal episodes or episodes with nocturnal stress. nonetheless, it has become severe enough for him when he saw his primary care physician and requested that he undergo a repeat catheterization which demonstrated the following, three vessel disease in the right dominant system. the left main had a distal tapering, 30% stenosis, the proximal left anterior descending was diffusely diseased and heavily calcified and mid left anterior descending had a discreet 70% stenosis, the distal left anterior descending was diffusely diseased and was also 70 to 80% stenosis in its distal portion. the circumflex had a calcified proximal 90% stenosis, om-1 had a proximal high grade stenosis, the dominant right coronary artery had a serial 50-60% stenoses in his proximal and mid portions. the rpda had a diffuse disease. ventriculography was not performed. again, these findings had triple vessel disease and the patient with progressive angina. he was referred to dr. for coronary artery bypass graft. past medical history: significant for coronary artery disease, insulin dependent diabetes mellitus, arthritis, positive exercise tolerance test as well as hypercholesterolemia. past surgical history: significant for vasectomy. allergies: he has no known drug allergies although he does have severe nausea and vomiting with .............. medications on admission: included; 1. enteric coated aspirin 325 mg p.o. q.d. 2. cardizem 240 mg p.o. q.d. 3. atenolol 225 mg p.o. q.d. 4. lescol 40 mg p.o. q.d. 5. captopril 25 mg p.o. q.d. 6. nph insulin 20/30 units subcutaneous b.i.d. social history: significant for past history of smoking. review of systems: negative for hypertension and transient ischemic attacks or cerebrovascular accident or melena/gi bleed. physical examination: on admission, the patient was with supple neck without jugular venous distention or carotid bruits. his cardiac examination is regular rate and rhythm, s1, s2 with a 2/6 systolic ejection murmur at the left sternal border. his chest was clear to auscultation bilaterally. his abdomen was soft, nontender, nondistended. extremities had good pulses. hospital course: on , he was admitted to the where he underwent a coronary artery bypass graft times four as follows; left internal mammary artery to left anterior descending, saphenous vein graft to diagonal 1, saphenous vein graft to obtuse marginal, saphenous vein graft to posterior descending artery. the cardiopulmonary bypass time was 151 minutes, cross clamp time was 114 minutes. this was performed by dr. . postoperatively he did well. he did not require any significant pressors or anatropes. his ejection fraction intraoperatively was 50%. postoperatively, he was transferred to floor. on postoperative day two his chest tubes had been removed without complication. however, the patient did develop an episode of rapid atrial fibrillation treated with 30 mg of lopressor as well as amiodarone for rate control. the patient's electrolytes were corrected during this time. electrocardiogram was obtained while he was in atrial fibrillation which did not show any evidence of ischemia. the patient did not complain of any chest pain, shortness of breath. the patient was treated with amiodarone, however, he had several repeat episodes on postoperative day three and required addition of diltiazem for rate control. at this point it was felt that because he had not converted to normal sinus rhythm he should be treated with anticoagulation. he was started on heparin drip with a target ptt of 40 to 30 and begun on oral anticoagulation with coumadin. by postoperative day number six, he had achieved a therapeutic inr of 1.9. at this time, he was tolerating a regular diet on p.o. pain medications. he was in a stable rate of 60 and a normal sinus rhythm with a blood pressure in the 130/70. he was clear to auscultation. he had regular rate and rhythm. sternum was no erythema, induration or drainage. he did have 1+ pitting edema in the extremities. given that he was in good condition, ambulating well he was deemed stable for discharge. he was discharged on the following medications. discharge medications: 1. lasix 20 mg p.o. b.i.d. 2. potassium chloride 20 meq p.o. b.i.d. while on lasix. 3. zantac 150 mg p.o. b.i.d. 4. colace 100 mg p.o. b.i.d. 5. aspirin 81 mg p.o. q.d. 6. lescol 40 mg p.o. q.d. 7. nph 20 to 30 units subcutaneous b.i.d. to be administered by the patient. 8. amiodarone 400 mg p.o. t.i.d. for 2 days and then 2 mg p.o. b.i.d. times 7 days, then 2 mg p.o. ................. , 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 diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome pure hypercholesterolemia unspecified essential hypertension cardiac complications, not elsewhere classified atrial fibrillation family history of ischemic heart disease diabetes mellitus without mention of complication, type i [juvenile type], not stated as uncontrolled 

Answer: The patient is high likely exposed to
