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: his past medical history is significant with chronic anemia, history of pe with an ivc filter in place, chronic venous stasis ulcers and disease, colon cancer status post colectomy in the 70s. medications: he was on aspirin. he was on a heparin drip. he was on imdur 30 mg q day, hydroxyzine, and lisinopril. he had no known drug allergies. his lungs were clear to auscultation bilaterally. his heart was regular rate, but bradycardic. his abdomen was soft, nontender, nondistended. bowel sounds are present. he had a positive colectomy. he had good pulses. he was taken to the operating room on where a cabg x2 was performed. the patient had a lima to left anterior descending artery, a -tex graft to the right rda and a left radial to om. the patient was transferred to the sicu postoperatively. he was slowly weaned from his ventilator and was extubated. he was also started on plavix for his radiograph as well as for his -tex graft. he continued to do well. the patient's monitor was slowly turned off, and he was found to be significantly bradycardic and electrophysiology was consulted. electrophysiology saw the patient and found that he has had bradycardic heart rate. it was decided at that time for a pacemaker to be placed, and it is scheduled to be done after discharge at a cardiac rehab facility. physical therapy was also consulted to assess ambulation, and he did well. however, physical therapy agreed with electrophysiology in requesting patient go to rehabilitation for potential increased physical therapy and range of motion. patient was transferred to the floor postoperatively and he continued to improve. foley was removed. he was unable to urinate, therefore foley was replaced. patient was not started on beta blockade because for his sinus bradycardia and for antinodal blockade. the patient was continued on the pacemaker at that time and continued on imdur and plavix for his graft. his pacer was set for ddi at 60. he continued to improve at that time. on postoperative day #7, the patient was discharged to rehab facility in stable condition with plan to have a pacer placement at that time. the patient was discharged. discharge medications include imdur 30 mg po q day, plavix 75 mg po q day, captopril 12.5 mg po tid, percocet 1-2 tablets po q4 hours prn, aspirin 325 mg po q day, zantac 150 mg po bid, colace 100 mg po bid, lasix 20 mg po bid, and 20 meq po bid. patient is discharged to rehabilitation in stable condition instructed to followup with primary care physician weeks. also follow up with cardiology after his pacer as needed and follow up with dr. in four weeks. the patient was discharged to rehab in stable condition. , 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 initial insertion of dual-chamber device initial insertion of transvenous leads [electrodes] into atrium and ventricle diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome congestive heart failure, unspecified hematoma complicating a procedure personal history of malignant neoplasm of large intestine other second degree atrioventricular block 

Answer: The patient is high likely exposed to
