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, hypercholesterolemia, coronary artery disease, pacemaker, and gastritis. medications: included metoprolol, protonix, isosorbide dinitrate, plavix, enalapril, aspirin, gabapentin, acetaminophen, and parenteral nutrition. discharge summary of hospital course: the patient was admitted on . he underwent his exploratory laparotomy and bowel resection on . prior to his surgery, he underwent an ivc filter placement. there was a clot in his iliac vessels which was likely chronic that we did not want to propagate and give him a pulmonary embolus. his subsequent course was complicated by anastomotic leak requiring percutaneous drainage. he did not significantly improve with this and surgical re-exploration was not requested by the family. due to deterioration, he was made comfortable and he subsequently expired on . a post mortem exam was declined by the family. , md procedure: venous catheterization, not elsewhere classified venous catheterization, not elsewhere classified continuous invasive mechanical ventilation for 96 consecutive hours or more parenteral infusion of concentrated nutritional substances other enterostomy diagnostic ultrasound of heart insertion of endotracheal tube interruption of the vena cava enteral infusion of concentrated nutritional substances percutaneous abdominal drainage temporary tracheostomy pulmonary artery wedge monitoring open and other sigmoidectomy transfusion of packed cells injection or infusion of oxazolidinone class of antibiotics diagnoses: acidosis subendocardial infarction, initial episode of care congestive heart failure, unspecified unspecified essential hypertension iron deficiency anemia secondary to blood loss (chronic) severe sepsis aortocoronary bypass status percutaneous transluminal coronary angioplasty status methicillin susceptible staphylococcus aureus septicemia other specified procedures as the cause of abnormal reaction of patient, or of later complication, without mention of misadventure at time of procedure blood in stool methicillin susceptible pneumonia due to staphylococcus aureus pressure ulcer, lower back acute venous embolism and thrombosis of deep vessels of proximal lower extremity mechanical complication due to cardiac pacemaker (electrode) fistula of intestine, excluding rectum and anus disruption of external operation (surgical) wound diverticulitis of colon (without mention of hemorrhage) infection and inflammatory reaction due to cardiac device, implant, and graft abscess of intestine 

Answer: The patient is high likely exposed to
