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: mr. is a 68-year-old patient of dr. who was referred for an outpatient cardiac catheterization on due to progressive exertional angina and a positive cardiac mri. he is a 68-year-old marathon runner who reported a three to four month history of exertional angina who stated that he had been having symptoms of mild back and substernal chest discomfort that radiated down both arms when running or walking quickly. these symptoms always resolved with rest. he stated that he had also been feeling the need to belch frequently. the patient apparently underwent a cardiac catheterization in and was medically managed for his coronary artery disease. on the patient had a cardiac mri which revealed mild lv enlargement with an ejection fraction of 43% and multiple wma consistent with multivessel disease. he has not had any symptoms occurring at rest or waking him from sleep. the patient denied any claudication, orthopnea, edema, paroxysmal nocturnal dyspnea or lightheadedness. past medical history: 1. hypertension 2. hypercholesterolemia 3. coronary artery disease social history: two cigars per week smoking. surgical history: 1. left knee arthroscopy 2. appendectomy family history: father with angina in his 50s who died of a myocardial infarction at the age of 68. allergies: he has no known drug allergies. admission medications: 1. aspirin 81 mg p.o. q.d. 2. lipitor 10 mg p.o. q.d. 3. cozaar 50 mg p.o. q.d. 4. atenolol 25 mg p.o. q.d. 5. multivitamin he was seen and underwent a cardiac catheterization at the on which demonstrated an ejection fraction of 40%, apical akinesis, anterolateral and inferior hypokinesis on this right dominant system with left main 80% distal disease involving the bifurcation. lad was occluded after the first diagonal. the left circumflex showed mild disease. the mild disease of the om1 and av branch. the rca showed 40% mid and 19% distal disease before the bifurcation. secondary to these findings the patient was referred to dr. for coronary artery bypass grafting. hospital course: the patient was admitted to the after cardiac catheterization and was taken to the operating room on where he underwent a coronary artery bypass grafting x4 as follows: left internal mammary artery to lad, saphenous vein graft to om with a jump graft to a diagonal and saphenous vein graft to our pda. his postoperative ejection fraction was 50%. the procedure was performed by dr. , assisted by dr. , as well as dr. . postoperatively, the patient went to the cardiothoracic surgery recovery unit. he required some neo-synephrine to maintain his blood pressure as well as some fluids and he did very well. he did, however, have a significant rub noted on auscultation. he had some episodes of atrial fibrillation for which amiodarone was added. on postoperative day #1, serial electrocardiograms were performed which demonstrated mild st segment elevations in leads v2 and v3 with tapering of the t-waves. given concern that these may have represented ischemia, a bedside transthoracic echocardiogram was obtained which showed good lv contractile function of the anterior wall, basal, anterior septum inferior and lateral walls. the apex and distal anterior septum were not well seen. there was no evidence of tamponade based on this and overall the ejection fraction was mildly depressed. the echocardiogram was not consistent with any new wall motion abnormalities and the patient was diagnosed as having postoperative pericarditis. he was kept in the cardiothoracic surgery recovery room until postoperative day #2, when he was transferred to the floor. his chest tubes were removed without complications. the patient ambulated early and was transfused 1 unit of packed red blood cells during his postoperative course. by postoperative day #4, he was without complaints, able to ambulate upstairs. he was afebrile and hemodynamically stable. his rhythm was regular. his sternum was stable and dry and his extremities demonstrated minimal edema. his hematocrit was 27.5 and he was doing well enough that it was felt that he was stable for discharge. the patient was tolerating a regular diet. discharge medication: 1. lopressor 25 mg p.o. b.i.d. 2. lasix 20 mg p.o. b.i.d. for 7 days 3. potassium chloride 20 milliequivalents p.o. b.i.d. for 7 days 4. colace 100 mg p.o. b.i.d. 5. protonix 40 mg p.o. q.d. 6. aspirin 81 mg p.o. q.d. 7. motrin 400 mg q6h prn 8. amiodarone 400 mg p.o. t.i.d. for 2 days, then 400 mg p.o. b.i.d. for 2 days, then 400 mg p.o. q.d. 9. percocet 1 to 2 p.o. q 4 to 6 hours prn discharge diagnoses: 1. coronary artery disease with angina, status post coronary artery bypass grafting x4 2. hypertension 3. hypercholesterolemia discharge instructions: he was instructed to follow up with dr. in two to four weeks. dr., r. 02-358 dictated by: medquist36 procedure: (aorto)coronary bypass of three coronary arteries single internal

Answer: The patient is high likely exposed to
