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: past medical history: history was significant for stable angina, status post cardiac catheterization in and hypertension. medications: (home) 1. aspirin 325. 2. isordil. 3. lopressor. hospital course: the patient was taken by dr. to the operating room on for cabg times five with svg to om-1 and om-2 and to diagonal svg to lad and svg to rca. the procedure was somewhat complicated by the patient going into arrest upon induction. the patient was placed in the intra-aortic balloon pump. postoperatively, the patient did well, extubated, and went off drips. on postoperative day #2, the intra-aortic balloon pump was discontinued without any complication or incident. on postoperative day #4, the patient was feeling well. the patient would like to be discharged home. the patient was able to ambulate to cardiac-status level v. in discharge, the patient was able to climb stairs. arrangement was made for the patient to have home nursing care. the patient was to followup. discharge medications: 1. lopressor 12.5 mg p.o.b.i.d. 2. aspirin 81 mg p.o.q.d. 3. lasix 20 mg p.o.b.i.d. times seven days. 4. -ciel 20 meq p.o.b.i.d. times seven days. 5. amiodarone 400 mg p.o.q.d. upon discharge, the patient's condition was stable. chest was clear. the patient was in regular sinus rhythm. incision was clean, dry, and intact, no drainage, no pus, sternum stable. the patient did have some serosanguinous drainage from the right lower extremity incision site for the donor, saphenous-vein site. there was no warmth, no erythema, no infection. the patient was discharged with instruction to followup with dr. in three to four weeks. instructions were given to the visiting nursing service to check up on the wound and pay particular attention to the right lower extremity vein-donor site. the patient was stable on discharge. dr., e. 02-248 dictated by: medquist36 procedure: extracorporeal circulation auxiliary to open heart surgery angiocardiography of left heart structures left heart cardiac catheterization coronary arteriography using a single catheter (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 unspecified essential hypertension other and unspecified angina pectoris cardiac arrest ventricular fibrillation 

Answer: The patient is high likely exposed to
