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: the patient is a 73-year-old male with a long history of coronary artery disease (including multiple coronary artery bypass grafts in , in , and in ; and several percutaneous transluminal coronary angioplasties) who was transferred to the c-med service from the coronary care unit. the patient was initially admitted to the on for an episode of substernal chest discomfort while driving his car to a family event. in addition to the chest discomfort, the patient also had the abrupt onset of shortness of breath and nausea. all of his symptoms, except the shortness of breath, were relieved with sublingual nitroglycerin. the patient states he had been doing well since his prior ct surgery back in ; denying any chest pain since discharge. he has not noticed any significant decrease in his exercise tolerance; however, he does admit to some mild lower extremity swelling and some shortness of breath at night while lying flat. an echocardiogram performed at the was significant for a dilated left ventricle with severe left ventricular dysfunction with an ejection fraction of 15% to 20%, 4+ mitral insufficiency, and trace aortic insufficiency. he was subsequently transferred to the for cardiac catheterization. a diagnostic cardiac catheterization at revealed multivessel disease with elevated pulmonary capillary wedge pressure of 34. he was transferred to the coronary care unit without any intervention at that time, where he was aggressively diuresed with intravenous lasix with a subsequent relief of his shortness of breath symptoms. secondary to decreased blood pressures while in the coronary care unit, his dose of beta blocker was lowered, and his blood pressure subsequently normalized. the patient was then transferred to the c-med service for repeat cardiac catheterization with definitive intervention and perfusion study. past medical history: 1. coronary artery disease with acute myocardial infarction complicated by ventricular fibrillation arrest in ; status post coronary artery bypass graft in of the saphenous vein graft to the left anterior descending artery. a redo coronary artery bypass graft in with saphenous vein graft to right coronary artery and saphenous vein graft to first diagonal. a redo coronary artery bypass graft in with left internal mammary artery to the left anterior descending artery, radial to posterior descending artery, saphenous vein graft to first diagonal, saphenous vein graft to first obtuse marginal to second obtuse marginal. 2. hepatitis b (acquired through a blood transfusion). 3. hypertension. 4. left bundle-branch block. 5. congestive heart failure by echocardiogram with 15% ejection fraction. 6. mitral regurgitation (4+ by echocardiogram in ). allergies: the patient states he has a penicillin allergy which causes a rash. he also states that morphine drops his blood pressure significantly. codeine, sulfa, iodine, and new allergy to rapid intravenous benadryl infusion; stating that he had throat tightness. medications on transfer: enteric-coated aspirin 325 mg p.o. q.d., lopressor 25 mg p.o. b.i.d., captopril 12.5 mg p.o. t.i.d., lipitor 20 mg p.o. q.d., protonix 40 mg p.o. q.d., plavix 75 mg p.o. q.d., colace 100 mg p.o. b.i.d. physical examination on presentation: the patient's vital signs revealed a temperature of 98, blood pressure was 100/64, heart rate was 89, respiratory rate was 18. he had an oxygen saturation of 95% on room air. in general, he was a very pleasant man, sitting in a chair, in no acute distress. head, eyes, ears, nose, and throat examination revealed no carotid bruits that were identifiable. no jugular venous distention was appreciated. his neck was supple, and sclerae were anicteric. cardiovascular examination revealed a diminished first heart sound, second heart sound, and a possible third heart sound gallop heard occasionally. tachycardic with a to 3/6 systolic ejection murmur heard best at the left upper sternal border and right upper sternal border radiating to the carotids. the murmur was heard over the entire precordial region. there was also a possible diastolic component as well. lung examination revealed lungs were clear to auscultation bilaterally. the abdomen was soft, nontender, and nondistended, with present bowel sounds. the extremities revealed 1+ lower extremity edema, cool, but well perfused, with 1 to 2+ pedal pulses bilaterally. pertinent laboratory data on presentation: laboratory findings on transfer revealed the patient had a white blood cell count of 4.3, hematocrit was 34.1, platelets were 178. sodium was 141, potassium was 4, chloride was 106, bicarbonate was 25, blood urea nitrogen was 21, creatinine was 0.6, with a blood glucose of 100. hospital course: on hospital day seven, the patient was returned to the cardiac catheterization laboratory for definitive treatment of his substernal chest discomfort. his first diagnostic cardiac catheterization revealed an 80% stenosis at the saphenous vein graft to obtuse marginal jump graft at the touchdown of the second obtuse marginal. a functional assessment of the stenosis was performed using a pressure wire showing a pressure gradient across the stenosis decreased from 0.79 to 0.69. the patient underwent successful percutaneous transluminal coronary angioplasty plus stent of the saphenous vein graft to first obtuse marginal to second obtuse marginal at the touchdown of the second obtuse marginal segment. overall, he tolerated the procedure quite well. on arrival to the floor, the patient was somewhat dizzy and moderately hypotensive; however, this quickly resolved without any intervention needed. subsequent electrolytes, and hematocrits, and cardiac enzymes were all stable and within normal limits. on hospital day eight, the patient was chest pain free, doing quite well, fully ambulatory, and without any symptoms of shortness of breath. he was felt to be stable for discharge home at this time. during his hospital course, the patient did have one episode of nonsustained ventricular tachycardia (a 6-beat run). he was asymptomatic during this episode and spontaneously converted to a normal sinus rhythm. no further intervention was necessary at this time. discharge followup: the patient was to follow up with dr. in his outpatient cardiac clinic as needed for adjustment of his blood pressure medications. medications on discharge: 1. enteric-coated aspirin 325 mg p.o. q.d. 2. zestril 5 mg p.o. q.d. 3. plavix 75 mg p.o. q.d. (times 30 days). 4. lopressor 25 mg p.o. b.i.d. 5. lipitor 20 mg p.o. q.d. 6. sublingual nitroglycerin as needed for chest pain. discharge status: discharge status was to home. condition at discharge: condition on discharge was stable. discharge diagnoses: 1. coronary artery disease; status post three coronary artery bypass grafts. 2. status post percutaneous transluminal coronary angioplasty plus stent to the saphenous vein graft to first obtuse marginal to second obtuse marginal at the second obtuse marginal touchdown. 3. hepatitis b. 4. hypertension. 5. left bundle-branch block. 6. congestive heart failure by echocardiogram with 15% ejection fraction. 7. mitral regurgitation (4+ on echocardiogram). , m.d. dictated by: medquist36 procedure: insertion of non-drug-eluting coronary artery stent(s) coronary arteriography using two catheters angiocardiography of left heart structures injection or infusion of platelet inhibitor left heart cardiac catheterization diagnoses: intermediate coronary syndrome congestive heart failure, unspecified unspecified essential hypertension coronary atherosclerosis of unspecified type of vessel, native or graft aortocoronary bypass status old myocardial infarction 

Answer: The patient is high likely exposed to
