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 66 year old male presented to an outside hospital with midsternal chest pain. electrocardiogram was taken and showed st changes. he underwent cardiac catheterization which showed multivessel disease with an ejection fraction of 45%. he was transferred to for coronary artery bypass graft. past medical history: significant for: 1. myocardial infarction in . 2. perforated diverticulitis with colostomy and closure. 3. status post incisional hernia. 4. rheumatoid arthritis. medications on admission: 1. lisinopril 7.5 mg p.o. once daily. 2. heparin drip. 3. protonix 40 mg p.o. once daily. 4. lipitor 20 mg p.o. once daily. 5. folic acid. 6. plavix 75 mg p.o. once daily. 7. aspirin 325 mg p.o. once daily. allergies: he had no known drug allergies. physical examination: he was afebrile and vital signs were stable. his extraocular movements were intact. his neck was supple. his lungs were clear. the heart was regular rate and rhythm, no murmurs, rubs or gallops. the extremities were warm and well perfused. hospital course: he was taken to the operating room on , where coronary artery bypass graft times three was performed, left internal mammary artery to left anterior descending, saphenous vein graft to om1, saphenous vein graft to om2 was performed. the patient was transferred to the csru postoperatively and was able to be quickly weaned and extubated. the patient did well in the csru and his oxygen was weaned. he was transfused two units. chest tube was left in for high output. the patient was transferred to the floor postoperatively and nearly postoperative he was complaining of abdominal pain. he was given morphine for this abdominal pain. a kub was taken which showed no small bowel obstruction, no dilated loops, however, he continued to have difficulty passing stool. however, he continued to have positive flatus. postoperatively, he began to become nauseous and nasogastric tube was placed with high output. he continued to pass flatus and had bowel movements. the nasogastric tube was clamped and residual was checked which was low and the nasogastric tube was removed. the patient was continued on npo status and intravenous fluids. general surgery was consulted at that time and suggested continuing management with repeat kub which continued to improve. his abnormal examination continued to improve throughout this time. postoperatively, physical therapy was consulted to evaluate his ambulation and his endurance and he continued to do well with physical therapy and planned for possible discharge to home. his lopressor was increased postoperatively for better rate control and furthermore, he had episodes of rapid atrial fibrillation which were unable to be converted with intravenous lopressor. he was started on amiodarone with intravenous bolus and then to 400 mg p.o. amiodarone. amiodarone was held during the episodes of nausea and vomiting with nasogastric tube placement. the patient was converted to sinus rhythm during that time, however, amiodarone was continued for prophylaxis. the patient continued to improved and his nasogastric tube was removed. he continued to ambulate with physical therapy. at the time of dictation, the patient was planned to be discharged to home with home services and continues to be in sinus rhythm. medications on discharge: (at this time) 1. amiodarone 400 mg p.o. once daily. 2. lasix 20 mg p.o. twice a day. 3. aspirin 325 mg p.o. once daily. 4. protonix 40 mg p.o. once daily. 5. lopressor 100 mg p.o. twice a day. 6. potassium chloride 20 meq p.o. twice a day. 7. atorvastatin 20 mg p.o. once daily. 8. percocet one to two tablets p.o. q4hours p.r.n. for pain. 9. colace 100 mg p.o. twice a day. the current plan is for the patient to be discharged home in stable condition with vna services. he was instructed to follow-up with dr. in four weeks as well as his primary care physician in one to two weeks and follow-up with cardiology in two to four weeks. the patient was discharged home in stable condition. please refer to addendum for any changes and discharge date. , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery (aorto)coronary bypass of two coronary arteries diagnostic ultrasound of heart other esophagoscopy diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome unspecified essential hypertension cardiac complications, not elsewhere classified atrial fibrillation surgical operation with anastomosis, bypass, or graft, with natural or artificial tissues used as implant causing abnormal patient reaction, or later complication, without mention of misadventure at time of operation old myocardial infarction paralytic ileus 

Answer: The patient is high likely exposed to
