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: hypertension. hyperlipidemia. colostomy after colon resection due to colon cancer. allergies: the patient states no known drug allergies. medications on admission: 1. atenolol 25 q.d. 2. norvasc 10 q.d. 3. zocor 20 q.d. 4. plavix 75 q.d. social history: lives in with his wife. is very independent and active. denies alcohol use. denies tobacco use. family history: no significant family history. physical examination: height 5'7". weight 197 pounds. vital signs: afebrile. heart rate 63, sinus rhythm, blood pressure 143/69, respiratory rate 16, and o2 saturation 94 percent on room air. general: lying flat in bed in no acute distress. neurologic: alert and oriented times three, nonfocal examination. cranial nerves are grossly intact. neck is supple. no lymphadenopathy and no bruits. respiratory: clear to auscultation bilaterally. cardiovascular: regular rate and rhythm, s1, s2, with no murmurs, rubs, or gallops. abdomen is soft, nontender, nondistended with normoactive bowel sounds. colostomy with a pink stoma. extremities are warm and well perfused with no edema or varicosities. pulses: radial 2 plus bilaterally. dorsalis pedis 2 plus bilaterally. posterior tibial 2 plus bilaterally. femoral 1 plus bilaterally. laboratory data: white count 6.4, hematocrit 43.3, platelets 170. pt 15.5, ptt 34.3, inr 1.5. sodium 136, potassium 4.1, chloride 104, co2 23, bun 14, creatinine 0.9, and glucose 210. alt 19, ast 14.8, alkaline phosphatase 70, amylase 74, total bilirubin 0.6, albumin 3.7. urinalysis was negative. ekg: sinus bradycardia with left anterior fascicular block. nonspecific st changes. chest x-ray: small rounded opacity noted in the left lung base likely representing a nipple shadow. hospital course: as stated previously, the patient was a direct admission to the operating room, where he underwent coronary artery bypass grafting x4. please see the or report for full details. in summary, the patient had a cabg x4 with a free lima to the lad, saphenous vein graft to diag, saphenous vein graft to om, and saphenous vein graft to the pda. his bypass time was 101 minutes with a cross-clamp time of 63 minutes. he tolerated the operation well. was transferred from the operating room to the cardiothoracic intensive care unit. patient did well in the immediate postoperative period. his anesthesia was reversed. his sedation was discontinued and he was successfully weaned from the ventilator and extubated. he remained hemodynamically stable throughout the day of his surgery requiring a neo-synephrine infusion to maintain an adequate blood pressure. on postoperative day one, patient continued to do well. he remained hemodynamically stable. his neo-synephrine drip was weaned to off. his chest tubes were removed. diuresis was begun and he stayed in the cardiothoracic intensive care unit because he was on neo-synephrine drip during part of the day. on postoperative day two, the patient continued to remain hemodynamically stable. his diuretics were increased. central lines were discontinued, and he was transferred to the floor for continuing postoperative care and cardiac rehabilitation. once on the floor, the patient had an uneventful hospital course. his activity level was gradually advanced with the assistance of the nursing staff and physical therapy. he was noted to have several short bursts of svt for which his beta blockade was increased. on postoperative day six, it was decided that the patient was stable and ready to be discharged to home. at the time of this dictation, patient's physical exam is as follows: vital signs: temperature 98.8, heart rate 77, sinus rhythm, blood pressure 113/75, respiratory rate 20, and o2 saturation 94 percent on room air. weight preoperatively 95 kg. at discharge, 92.2 kg. laboratory data: hematocrit 25.9, sodium 136, potassium 4.5, chloride 99, co2 28, bun 22, creatinine 1.1, glucose 127. physical exam: neurologically: alert and oriented times three. moves all extremities, follows commands. nonfocal exam. respiratory: clear to auscultation bilaterally. cardiovascular: regular rate and rhythm, s1, s2. sternum is stable. incision with steri- strips open to air clean and dry. abdomen is soft, nontender, nondistended with normoactive bowel sounds. colostomy with pink stoma. extremities are warm and well perfused with 1 plus edema. right saphenous vein graft site with steri-strips open to air, clean and dry. condition on discharge: good. disposition: he is to be discharged to home with visiting nurses. discharge diagnoses: coronary artery disease status post coronary artery bypass grafting x4 with a free left internal mammary artery to the left anterior descending artery, saphenous vein graft to diagonal, saphenous vein graft to obtuse margin, saphenous vein graft to posterior descending artery. hypertension. hypercholesterolemia. colon cancer status post colectomy with colostomy. diabetes mellitus type 2. follow-up instructions: the patient is to have followup in the clinic in two weeks. follow up with dr. in weeks. follow up with dr. in four weeks. discharge medications: 1. oxycontin 5/325 1-2 tablets q.4h. prn. 2. lasix 20 mg q.d. for two weeks. 3. aspirin 325 q.d. 4. metoprolol 50 mg b.i.d. 5. potassium chloride 20 meq q.d. for two weeks. 6. simvastatin 20 mg q.d. 7. niferex 150 mg q.d. x1 month. discharge instructions: additionally, the patient is to check his fingerstick blood sugars t.i.d. with results being reported to his primary care provider. , m.d. procedure: (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome pure hypercholesterolemia unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled personal history of malignant neoplasm of large intestine
