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: erythromycin base / ampicillin / levofloxacin / clindamycin attending: chief complaint: bradycardia major surgical or invasive procedure: pacemaker placement history of present illness: y/o gentleman with htn, chf, cad s/p cabg 80s, af on coumadin has experienced diarrhea since yesterday afternoon. he came to the emergency department to better manage his fluid status per pcp . in the emergency department his hr was found to be in high 30s to low 40s. his baseline has been mid to high 40s for the last few years. patient has experienced dypnea on exertion with approx 30-40 feet of walking in the last 1 week. denies chest pain, orthopnea, pnd, palpitations, or lower extremity edema. daughter has noticed that he has gained 5 lbs in the last one week. he has had three loose bowel movements since yesterday afternoon. no new food, blood in stool, fever, chills, or night sweats. denies any pain. in ed vitals were: hr 35, no cp, bp 130s/60 97%ra. . past medical history: chf (last known ef 49%) dm2 hypothyroid atrial fibrillation cad s/p cabg, exercise mibi 1) moderate, fixed defect involving the base of the inferolateral wall. 2) ejection fraction of 49% with septal and inferolateral wall hypokinesis. ckd baseline cr 2.0-2.5 htn hx pud glaucoma osteopenia macular degeneration r eye cataract left eye blind hoh upper and lower dentures . social history: retired postal worker, lives alone in but daughter is very involved, organizes meds for him. widowed 8 years ago. . family history: diabetes, htn physical exam: vitals: t 97.7 bp 140/59 hr 70 rr 18 100% on 2lnc gen: alert and jovial. oriented to person and place. nad heent: perrl, mmm, op clear, jvp not elevated heart: s1s2 regularly regular bradycardic lungs: fine bibasilar crackles abdomen: soft ntnd extremities: 1+ pitting edema in b/l lower extremities neuro: spont moves . pertinent results: admit labs: 05:15pm blood wbc-4.6 rbc-3.67* hgb-12.3* hct-35.4* mcv-97 mch-33.5* mchc-34.6 rdw-14.0 plt ct-100* 05:15pm blood pt-24.3* ptt-31.5 inr(pt)-2.4* 05:15pm blood glucose-168* urean-106* creat-3.7*# na-140 k-4.7 cl-107 hco3-24 angap-14 05:55am blood glucose-139* urean-52* creat-2.2* na-140 k-3.8 cl-111* hco3-20* angap-13 05:15pm blood ctropnt-0.03* 05:15pm blood ck(cpk)-74 05:15pm blood ck-mb-notdone probnp-3419* 05:15pm blood albumin-4.2 calcium-9.1 phos-4.2 mg-2.8* 05:30am blood tsh-2.9 05:30am blood free t4-1.3 05:15pm blood k-4.6 . chest (portable ap) : mild interstitial edema with cardiomegaly. . tte : the left atrial volume is markedly increased (>32ml/m2). left ventricular wall thicknesses and cavity size are normal. there is moderate regional left ventricular systolic dysfunction with severe hypokinesis of the septum and inferior wall. the right ventricular cavity is not well seen but appears mildly dilated and probably hypertrophied. the ascending aorta is mildly dilated. there are three aortic valve leaflets. the aortic valve leaflets are moderately thickened. there is no aortic valve stenosis. no aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. there is no mitral valve prolapse. trivial mitral regurgitation is seen. there is moderate pulmonary artery systolic hypertension. there is no pericardial effusion. impression: moderate regional lv systolic dysfunction. dilatation and probable hypertrophy of the right ventricle, its function cannot be accurately assessed. moderate pulmonary artery systolic hypertension. biatrial enlargement. . chest (pa & lat) : 1. subtle line at the right lung apex with evidence of some lung markings beyond it, could represent a skinfold. followup radiograph to definitively exclude pneumothorax is recommended. this was discussed with dr. . 2. left chest wall transvenous pacer with right atrial and ventricular leads in standard location without a left pneumothorax. . brief hospital course: year old gentleman with hypertension, chronic right heart failure, coronary artery disease status post cabg in , atrial fibrillation on warfarin admitted with asymptomtic bradycardia and acute on chronic renal failure in the setting of recent diarrhea and weight gain. # rhythm: asymptomatic bradycardia, with history of atrial fibrillation. pt was admitted to the ccu for close monitoring. pt remained asymptomatic throughout his stay even though she had heart rates that dropped as low as high 20s. his coumadin was held and he received 2.5mg vitamin k on in preparation for pace maker placment. appreciate electrophysiology recommendations. a pace maker was placed on without complication. # pump: has fine crackles at bases and 1+ edema in ble. has right sided heart failure per out patient cardiologist () and elevated bnp. an echo was done which showed ef 30-35%, moderate regional lv systolic dysfunction. dilatation and probable hypertrophy of the right ventricle. moderate pulmonary artery systolic hypertension and biatrial enlargement. his lasix was held for some diarrhea and acute on chronic renal failure. he was discharged on decreased lasix dose of 20 mg twice daily. . #. cad: history of cad s/p cabg in 80s. remained asymtomatic during her stay here. he was continued on his statin. patient will have device clinic, electrophysiology and cardiology follow up as out patient. . # diarrhea: 3 large liquid bowel movements which resolved on admission. c.diff test was negative. most likely due to transient viral infection. . # chronic kidney disease: unclear baseline. his cr was 3.7 and trended down to 2.5 (felt to be baseline; but unclear). likely due to poor forward flow in the setting of bradycardia. his home lasix was held in setting of arf and restarted at decreased dose on discharge. his trandolapril was discontinued during this stay. . #
