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 55 year old gentleman had the recent onset of chest pressure. he developed chest pain on , took one sublingual nitroglycerin at this time with temporary improvement of chest pain that returned. he came in to the to be evaluated. past medical history: 1. in , the patient developed a large cell gastric lymphoma. he was treated with surgery, chemotherapy and radiation to the lower mediastinum. 2. in , the patient underwent an echocardiogram. ejection fraction at that time was 55 with plus one mitral regurgitation. there was a question of mobile aortic atheroma. subsequent transesophageal echocardiogram revealed some atherosclerosis in the aorta and a strand in one of the aortic cusps of unknown significance. the patient remained asymptomatic. 3. in , the patient began to use his treadmill at home to exercise and did well. 4. in , after a vacation in , the patient noted decrease in his exercise tolerance when using his treadmill and he stopped exercising at that time and remained asymptomatic. recently, when he was walking after eating, he reports classical angina pressure which abated after two minutes of rest. he went to his primary care practitioner of this new onset angina and was started on aspirin and atenolol at that time. he underwent a stress test that was strongly positive for multi-vessel disease and was recommended for cardiac catheterization follow-up. the patient denied anemia, asthma, congestive heart failure, chronic obstructive pulmonary disease, stroke, diabetes mellitus, gi bleed, hepatitis, hypertension, liver failure, prior stroke, pancreatitis. the patient does have a history of high cholesterol. social history: the patient is married and lives with wife. denies smoking. family history: father died of an myocardial infarction at 81. mother and siblings have no identifiable cardiac risk factors. medications upon admission: 1. atenolol. 2. aspirin. 3. lipitor. 4. vitamin e. review of systems: on admission were unremarkable. physical examination: on admission revealed a blood pressure of 112/70; a heart rate of 65. heent were benign. neck were without carotid bruits. chest: heart was regular. no murmurs. respiratory: lungs were clear. abdomen was soft, nontender, no masses. extremities were warm with normal pulses. laboratory: the patient underwent a cardiac catheterization on ; please refer to catheterization report for specific details. in summary findings revealed severe left main disease with a two-vessel coronary artery disease, biventricular diastolic dysfunction, moderate pulmonary arterial hypertension. an intra-aortic balloon pump was placed and the patient went for emergent coronary artery revascularization times five with a left internal mammary artery and a saphenous vein graft. please refer to the operative report for details of surgery. the patient was transferred to the intensive care unit postoperative with the preoperative intra-aortic balloon pump in place on nitroglycerin and propofol. the patient remained hemodynamically stable. on , the patient's balloon pump was weaned and discontinued and the intravenous nitroglycerin was weaned off. on , the patient was extubated, beta blockade initiated and he transferred out to the floor on postoperative day two. on postoperative day three, the patient began increasing his activity and remained hemodynamically stable. at that time, his epicardial wires and foley catheter were discontinued. ambulation and pulmonary toilet was encouraged. on postoperative day five, the patient remains hemodynamically stable. he is ambulating successfully and able to climb a flight of stairs and is being evaluated for discharge. the patient is hemodynamically stable. discharge physical examination: temperature 99.5 f.; heart rate 71 and regular; blood pressure 118/65; respiratory rate 20 with a saturation of 93 on room air. heent: grossly intact. neurologic: alert and oriented times three and moving equally with steady gait. cardiac: s1, s2 regular. no rub, no murmur appreciated. respiratory: no dyspnea, respiratory rate 20's. he does present with rales 2 cm down on the left and pa down on the right. he denies dyspnea. there is no wheezing, no cough. he was treated with lasix 40 intravenously times one prior to discharge. vascular: he is warm and dry. he has palpable pulses bilaterally. wound, chest and right leg incisions are open to air and they are dry and intact with steri-strips. there is no erythema and there is no drainage. on gi assessment, the patient has had no nausea or vomiting. abdomen was soft, positive bowel sounds, nontender. discharge status: the patient's discharge status is stable. discharge diagnoses: 1. coronary artery disease status post coronary artery bypass grafting times five. medications upon discharge: 1. lopressor 50 mg p.o. twice a day. 2. enteric coated aspirin 325 mg p.o. q. day. 3. lasix 40 mg q. a.m. times two weeks; lasix 20 mg p.o. q. p.m. times two weeks. 4. 20 meq p.o. twice a day times two weeks. 5. ibuprofen 400 mg p.o. q. six p.r.n. pain and discomfort. discharge medications: note, preoperative lipitor was not resumed due to an elevated alt on of 88 and an ast of 138 and a total bilirubin of 1.9. the patient is to follow-up with his primary care provider in three weeks. further, labs from , white blood cell count was 13.6 with a hemoglobin of 9.1, and hematocrit of 26.5 with a platelet count of 110. labs on , sodium of 139, potassium of 4.1, bun of 28 and a creatinine of 1.2 which remained stable and a glucose of 112. discharge instructions: 1. the patient will increase activity. 2. he will follow-up in the clinic in two weeks. 3. he will follow-up with his primary care physician in three weeks post discharge and he will be re-evaluated by dr. four weeks postoperatively. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery combined right and left heart cardiac catheterization coronary arteriography using two catheters injection or infusion of platelet inhibitor (aorto)coronary bypass of four or more coronary arteries implant of pulsation balloon diagnoses: subendocardial infarction, initial episode of care coronary atherosclerosis of native coronary artery other chronic pulmonary heart diseases personal history of other lymphatic and hematopoietic neoplasms 

Answer: The patient is high likely exposed to
