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 78 year old patient who reports having heaviness and shortness of breath with exertion and recently had a positive stress test and was referred to for cardiac catheterization. past medical history: 1. gastroesophageal reflux disease; 2. chronic back pain due to degenerative joint disease; 3. anxiety. allergies: ex-lax which causes hives. preoperative medications: 1. toprol xl 50 mg p.o. q.d. 2. diovan 160 mg p.o. q.d. 3. remeron 50 mg p.o. q.h.s. 4. evista 60 mg p.o. q.d. 5. prilosec 20 mg p.o. q.d. 6. multivitamin q.d. 7. calcium q.d. 8. plavix 75 mg p.o. q.d. 9. xanax .125 mg prn ho course: the patient was admitted to on for cardiac catheterization. cardiac catheterization showed a left ventricular ejection fraction of 72%, 70% left main coronary artery ostial stenosis, twin left anterior descending system with large single first diagonal branch with diffuse proximal calcification, 90% stenosis of the left anterior descending proximally to the takeoff of the first diagonal branch which has an 80% ulcerated stenosis at its ostium, 40% mid left circumflex and 95% right coronary artery stenosis. the patient was referred to dr. for coronary artery bypass surgery. the patient was taken to the operating room on for a coronary artery bypass graft times four, left internal mammary artery to left anterior descending, saphenous vein graft to right coronary artery, saphenous vein graft to obtuse marginal, saphenous vein graft to diagonal. the patient was transferred to the intensive care unit in stable condition on propofol and neo-synephrine infusion. the patient was weaned the next day from mechanical ventilation early on the first postoperative evening. on postoperative day #1 the patient continued to require low-dose neo-synephrine infusion to maintain adequate systolic blood pressure. the patient required aggressive pulmonary toilet maintaining oxygenation. on postoperative day #2 the neo-synephrine was weaned off. the patient was started on low dose beta blocker and lasix. the patient's pulmonary artery catheter was removed. on postoperative day #2 the patient was seen by physical therapy and over subsequent evaluations it was determined that the patient would benefit from a stay at rehabilitation. on postoperative day #3, the patient's chest tubes were removed. the patient's hematocrit was noted to be 23.2 which was felt to be dilutional and the patient was transfused 1 unit of packed red blood cells with post transfusion hematocrit of 27. on postoperative day #4, the patient was transferred from the intensive care unit to the regular part of the hospital where the patient continued to work with physical therapy and they again recommended, due to the patient's physical therapy level as well as the patient's social situation at home, the patient would be best served by rehabilitation. on postoperative day #5 the patient was noted to have periods of sinus tachycardia with rates into the 130s. this was thought to be due to a significant amount of anxiety about whether or not the patient would have to go home. the patient was reassured. the patient requested to be restarted on xanax as well as the patient's lopressor was increased with good control of her heartrate and by postoperative day #6 the patient was cleared for discharge to home. condition on discharge: temperature maximum 99.4, pulse 100, sinus rhythm, blood pressure 136/72, respiratory rate 14, room air oxygen saturation 94%. the patient's weight on postoperative day #6 is 65.8 kg. preoperatively the patient's weight was 63 kg. neurologically the patient was awake, alert and oriented times three, very anxious. heart regular rate and rhythm without rub or murmur. breathsounds clear bilaterally. abdomen was soft, nontender, positive bowel sounds, tolerating a regular diet. his lower extremities show 1 to 2+ pitting edema, left greater than right, extremities are warm and well perfused. external incision is clean and dry. steri-strips were intact. strength is stable. laboratory data: white blood cell count 9.3, hematocrit 30.2, platelet count 332, sodium 142, potassium 4.2, chloride 107, bicarbonate 27, bun 18, creatinine 0.7. discharge diagnosis: 1. coronary artery disease 2. status post coronary artery bypass graft 3. anxiety discharge medications: 1. aspirin 325 mg p.o. q. day 2. tylenol 650 mg p.o. q. 4 hours prn 3. protonix 40 mg p.o. q. day 4. xanax 0.125 mg p.o. q. 6 hours prn 5. lopressor 25 mg p.o. t.i.d. 6. colace 100 mg p.o. b.i.d. 7. remeron 50 mg p.o. q.h.s. prn condition on discharge: the patient is to be discharged to rehabilitation in stable condition. fop: the patient should follow up with her cardiologist, dr. in one to two weeks. the patient should follow up with her primary care physician, . in one to two weeks. the patient should follow up with dr. in one month. , 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 coronary arteriography using two catheters angiocardiography of left heart structures left heart cardiac catheterization diagnoses: anemia, unspecified coronary atherosclerosis of native coronary artery esophageal reflux unspecified essential hypertension anxiety state, unspecified other and unspecified angina pectoris spondylosis of unspecified site, without mention of myelopathy 

Answer: The patient is high likely exposed to
