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: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: diarrhea and icd fire major surgical or invasive procedure: none history of present illness: hpi: this is a yo m with a pmh of cad s/p cabg, s/p icd in , who p/w 1 week of diarrhea, fevers, and icd firing x4 yesterday. the pt states that over the past week, he has had many (<10) brown, watery stools, associated with lower abdominal cramping prior to bowel movements. the abdominal cramping is alleviated with bowel movements, and he is often incontinent of stool at this time. he states that his wife has told him he has had a temp over 100 f over the past week. he also notes that his icd fired 4 times yesterday as he was walking out of the bathroom, which has never happened to him before. he has had decreased po intake of foods and fluids over the past 3-4 days. he denies any palpitations, loc, chest pain, shortness of breath, dysuria, nausea, vomiting, headaches, cough, leg swelling, rashes, or chills. . of note, the pt was hospitalized at from /08 for probable urosepsis and positive blood cultures for e coli (grown in bottle from ). his e coli was pansensitive. he was treated with ctx while inpatient, and then discharged to rehab where he was treated with avelox for his positive blood culture. the pt was discharged from rehab 1 week ago, which is when he started to have diarrhea. . in the ed, the pts vitals were: tm 100.4, hr 102-128, bp 86-107/32-56, r 20-26, sat 96% 2l nc. he received 3 l ns, 2 l of lr, flagyl 500 mg iv x2, levofloxacin 500 mg iv x1, vanc 1 gm iv x1. blood cultures and urine cultures were drawn. because he was hypotensive to the 80s and tachy to the 120s, a right subclavian central line was placed. he was responsive to fluid boluses in the ed. he was seen by ep and icd interrogation revealed underlying af with rvr. initially he had rapid af, then regular ventricular rate cl 290: shock with 29j into rapid af, but still in vf detection zone: 5 more shocks. then another episode ad--> rapid regular tachycardia cl 260 msec: teminated while charging but therapy not aborted due to a few short coupled beats while in af. his vf detection range was changed to cl 320 msec. . he was given a total of 7.5l of fluid in his roughly 2 day stay in the micu and his blood pressure responded. he continued to be tachycardic, though was documented to be in sinus tach by ekg. his metoprolol was restarted on . . upon transfer, he denied cp, palpitations, sob, lightheadedness. past medical history: cad s/p cabg in for l main disease

the left atrium is moderately dilated. there is severe symmetric left ventricular hypertrophy. the left ventricular cavity is unusually small. there is mild global left ventricular hypokinesis (lvef = 40-50 %). tissue doppler imaging suggests an increased left ventricular filling pressure (pcwp>18mmhg). there is no ventricular septal defect. the right ventricular free wall is hypertrophied. right ventricular chamber size is normal. with depressed free wall contractility. the number of aortic valve leaflets cannot be determined. the aortic valve leaflets are moderately thickened. there is mild aortic valve stenosis (area 1.2-1.9cm2). no aortic regurgitation is seen. a mitral valve annuloplasty ring may be present. an eccentric, anteriorly directed jet of mild (1+) mitral regurgitation is seen. the tricuspid valve leaflets are mildly thickened. the supporting structures of the tricuspid valve are thickened/fibrotic. there is a trivial/physiologic pericardial effusion. . cxr : 1. slight decrease in the left small pleural effusion. 2. otherwise there is essentially no significant interval change. . ecg study date of 12:05:52 am probable sinus tachycardia with atrial premature

afib by device detection/firing, now looks like mat by ekg, likely related to volume depletion vs. sepsis upon admission. he is not on anticoagulation. will defer to outpatient physician for decision about anticoagulation given age and comorbidities. tsh wnl. ep consulted and recommended digoxin 0.0625, which was increased to 0.125 daily based on dig level. he will need a repeat dig level on . his lisinopril was held as above, and continued to be held to allow blood pressure room for beta blocker. will defer to rehab/primary care physician : restarting lisinopril, titrating digoxin. . #
