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 50-year-old male with a history of dilated nonischemic cardiomyopathy with an ef of 15, complete heart block status post vvi pacer, status post gastric bypass, several episodes of acute tubular necrosis in the past, presents to an outside hospital with five days of nausea, vomiting, watery diarrhea three times per day - no blood and no black. wife had been sick with diarrhea previously. no recent travel and no pnd or orthopnea. no increased lower extremity edema, chest pain or shortness of breath. wife notes that the patient has been very fatigued as of late, two days ago, as well as extremely confused. his wife, who is rn, noticed a systolic blood pressure to be in the 70's to 80's, but he normally has a baseline of 90. he continues to take his diuretics and his ace inhibitor while he was not taking any po and having massive diarrhea. he called ems, went to the outside hospital, was found to be in acute renal failure, acidotic, hyperkalemic, elevated inr, and sent to the . past medical history: dilated nonischemic cardiomyopathy with an ef of less than 15%, complete heart block status post ddd pacer in , replaced in , neuropathic pain, /ventral hernia, atrial fibrillation with left bundle branch block, and status post gastric bypass, trach postoperatively, ventral hernia repair, hospital course complicated by acute renal failure and trach and a baseline creatinine of 1.1. medications on admission: coumadin 5, enalapril 10 b.i.d., carvedilol 12.5 b.i.d., zantac 150 b.i.d., vitamin b12, lasix 120 b.i.d., aspirin 325, ativan 0.5 po b.i.d., neurontin 300 mg po b.i.d.. social history: remote tobacco. physical examination: on initial exam, the patient was alert and oriented. heent was anicteric. extraocular muscles were dry. neck: no jvd. supple. distant s1, s2. lungs: clear to auscultation anteriorly. abdomen: positive bowel sounds, obese. extremities: no edema, but scabbed excoriations. neuro: alert and oriented times three and conversant. hospital course: 1. renal. patient admitted in acute renal failure notable for a bun of 210 and creatinine 9.9. he also had elevated k with peaked t waves anteriorly. he was given emergent hemodialysis for three hours and was given aggressive iv fluid hydration and his urine output started to pick up to peaks of 400 cc an hour. he received swan-ganz catheter monitoring with wedges that were around 15-18. on the third day of his admission, the swan was discharged and he was continued to be aggressively rehydrated until his urine output came to more reasonable levels where he was able to keep up with his po intake. his acute renal failure resolved with only the one episode of hemodialysis, as did most of his hyperkalemia. 2. cardiac. the patient had an ef of 15%. his initial wedge was 22 and he was monitored closely during this resuscitation. he never went into failure. rhythm, his av is sequentially paced. he had peaked ts on first ekg which were then resolved. 3. hematology. patient had low hematocrit after his rehydration and was transfused two units. he was also given vitamin k to reverse his inr of 14. his inr did reverse on its own and was felt likely secondary to decreased po intake. his coumadin, as of this dictation, was still on hold. 4. gi. patient with diarrhea which had resolved for the first two days and then came back. stool studies were sent and the results are pending, as of the time of this dictation. 5. id. patient was evaluated by id for septic numbers on the swan. patient had low svr and a high cardiac output. it was felt there was no infectious source, although he did have a low grade fever. the patient was given one dose of levaquin for a presumed uti, which then the culture had no growth and was discontinued. discharge medications: the same as on admission. discharge status: good. discharge disposition: home. , m.d. dictated by: medquist36 procedure: venous catheterization for renal dialysis arthrocentesis diagnoses: other primary cardiomyopathies urinary tract infection, site not specified unspecified essential hypertension intestinal bypass or anastomosis status acute kidney failure, unspecified atrial fibrillation primary pulmonary hypertension cardiac pacemaker in situ 

Answer: The patient is high likely exposed to
