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 who was admitted with a significant history of coronary artery disease who was admitted for cardiac evaluation prior to surgery for an apple core lesion in the transverse colon. one month prior to admission the patient presented to his primary care physician with abdominal fullness and abdominal pain. a ct and barium enema revealed an apple core lesion in the transverse colon. the patient was not have any bright red blood per rectum, or melena, or hematemesis, or nausea or vomiting. he did not have any weight loss initially but over the last month he has lost eight pounds. the patient was admitted on , and was taken to the cardiac catheterization laboratory where he had a percutaneous transluminal coronary angioplasty. this revealed an ejection fraction of 25% as well as 80% narrowing in the left anterior descending artery, graft and circumflex graft. the patient is status post a 3-vessel coronary artery bypass graft times two in and . the patient also underwent a colonoscopy on which revealed a mass in the transverse colon of 70 cm from the anal verge as well as mass in the descending colon 25 cm from the anal verge. the patient was cleared by cardiology, and it was decided that he would be taken to the operating room on . past medical history: (significant for) 1. hypertension. 2. increased cholesterol. 3. coronary artery disease. 4. myocardial infarction. past surgical history: 1. three vessel coronary artery bypass graft times two in and . percutaneous transluminal coronary angioplasty on . 2. right inguinal hernia repair times three. 3. left inguinal hernia repair times one. 4. appendectomy. 5. umbilical hernia. 6. partial colectomy. 7. diverticulitis in with a colostomy and takedown of colostomy in . allergies: penicillin. medications on admission: 1. cartia xt 120 mg p.o. b.i.d. 2. atenolol 25 mg p.o. q.d. 3. lipitor 10 mg p.o. q.d. 4. aspirin 325 mg p.o. q.d. 5. 100 mg p.o. q.d. 6. zantac 150 mg p.o. b.i.d. social history: the patient is an ex-smoker. occasional ethanol. he is married. radiology/imaging: on , the patient underwent a catheterization which revealed severe 3-vessel disease with a right-dominant system, showing stent occlusions of all venous grafts with a patent left internal mammary artery. successful percutaneous transluminal coronary angioplasty of the middle first diagonal branch was obtained. barium enema revealed apple core lesion in the transverse colon. pertinent laboratory data on admission: white blood cell count of 7.2, hematocrit of 32.2, platelets 210. pt 12.1, ptt 18.1, inr 1. potassium 4.1, bun 14, creatinine 1.1. physical examination on presentation: the patient was afebrile, blood pressure 121/38, heart rate 92, 96% on room air. he was awake and alert, in no apparent distress. his lungs were clear to auscultation bilaterally. heart had a regular rhythm with slight bradycardia. his abdomen was soft and nondistended with minimal tenderness in the left lower quadrant. he also had a reducible umbilical hernia. he had no calf tenderness and no guarding. on rectal, there was frank blood with no masses (per gastrointestinal). extremities were warm, soft, nontender. no cyanosis, clubbing or edema. hospital course: the patient was admitted on , and he was taken to the catheterization laboratory on for percutaneous transluminal coronary angioplasty. the patient had some bright red blood per rectum times three after the percutaneous transluminal coronary angioplasty which was probably secondary to the integrilin that he was placed on. the patient was then taken for a colonoscopy on which revealed two lesions in his colon. on , the patient was taken to the operating room and underwent a subtotal colectomy. the patient tolerated the procedure well and was transferred to the postanesthesia care unit in stable condition. considering the patient's significant cardiac history, he remained intubated and was transferred from the postanesthesia care unit to the intensive care unit where he stayed overnight. on postoperative day one the patient remained stable. as his hematocrit dropped slightly he was given 1 unit of packed red blood cells, considering his cardiac history. on postoperative day two, the patient was extubated and transferred from the intensive care unit to the floor. his nasogastric tube remained in place. the patient's vital signs remained stable, as did his laboratories. his nasogastric tube output was replaced cc per cc, and his electrolytes were repleted. he received several doses of lasix as his breath sounds were quite coarse, and he was bringing up significant amounts of phlegm. he remained on intravenous lopressor as well as p.o. lopressor to keep his heart rate and blood pressure under control. he was also ruled out for a myocardial infarction; although his troponin did bump slightly. it was checked again and trended downward. there was no evidence for a myocardial infarction. the patient did well on postoperative day two. he had several bowel movements. on postoperative day three, his diet was advanced. that evening, the patient became quite nauseous and did not respond to antiemetics. he vomited several times. an nasogastric tube was replaced. his was made n.p.o., and all of his intravenous medications were restarted. on postoperative day four, the patient continued to remain n.p.o. with a nasogastric tube in place, and he was not having any flatus, although he did have bowel movement. his vital signs remained stable. on postoperative day five, the patient reported flatus and he was started on sips. his diet was advanced. he was seen by physical therapy early in his postoperative course. the patient was doing well and was ambulating. on postoperative day six, as the patient was tolerating a regular diet, was ambulating, and feeling good, it was decided that he would be discharged home. discharge status: the patient was discharged to home. condition at discharge: in stable condition. medications on discharge: 1. dilaudid 2 mg to 4 mg p.o. q.4-6h. p.r.n. for pain 2. iron sulfate 325 mg p.o. q.d. 3. cartia xt 120 mg p.o. b.i.d. 4. atenolol 25 mg p.o. q.d. 5. lipitor 10 mg p.o. q.d. 6. aspirin 325 mg p.o. q.d. 7. 100 mg p.o. q.d. 8. zantac 150 mg p.o. b.i.d. discharge followup: he was told to follow up with dr. in the office in one week for staple removal and to call or return with any questions or problems. , m.d. dictated by: medquist36 d: 18:10 t: 09:11 job#: procedure: coronary arteriography using two catheters angiocardiography of left heart structures injection or infusion of platelet inhibitor left heart cardiac catheterization other and unspecified partial excision of large intestine colonoscopy other small-to-large intestinal anastomosis diagnoses: coronary atherosclerosis of native coronary artery unspecified essential hypertension coronary atherosclerosis of autologous vein bypass graft other and unspecified angina pectoris benign neoplasm of colon diverticulosis of colon (without mention of hemorrhage) hemorrhage of rectum and anus malignant neoplasm of other specified sites of large intestine 

Answer: The patient is high likely exposed to
