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 58-year-old female with prior cardiac history significant for severe mitral regurgitation as well as severe tricuspid regurgitation, dilated cardiomyopathy with biventricular failure, and an estimated left ventricular ejection fraction of approximately 30%. she recently presented complaining of increased leg edema, increased abdominal distention, and weight gain for a few weeks. she has a history of a ddd pacemaker device placement. the patient denies any shortness of breath currently. she denies any palpitations or diaphoresis or chest pain. the patient was originally admitted to the medicine service. past medical history: 1. myocarditis at age 11 2. dilated cardiomyopathy with biventricular failure and estimated ejection fraction of 30% 3. severe tricuspid regurgitation 4. severe mitral regurgitation 5. atrial fibrillation/flutter with ddd pacer placed in 6. hypertension 7. chronic renal insufficiency 8. hypothyroidism 9. iron-deficiency anemia 10. history of methicillin resistant staphylococcus aureus pneumonia 11. peptic ulcer disease 12. migraine headaches 13. chronic sinusitis 14. panic disorder past surgical history: 1. billroth ii in 2. roux-en-y in 3. volvulus status post hemicolectomy and ileosigmoid anastomosis in 4. perforated small bowel obstruction allergies: 1. gentamicin 2. bactrim gives the patient headaches and pruritus. 3. chloramphenicol 4. penicillin medications on admission: 1. lasix 80 mg by mouth twice a day 2. captopril 12.5 mg by mouth three times a day 3. amiodarone 200 mg by mouth once daily 4. coumadin 7.5 mg by mouth once daily (discontinued on ) 5. synthroid 125 mcg by mouth once daily 6. actigall 200 mg by mouth twice a day 7. zaroxolyn 2.5 mg by mouth twice a day 8. prozac 80 mg by mouth once daily 9. fioricet as needed 10. 60 mg by mouth twice a day 11. nasacort spray as needed 12. multivitamin 13. potassium chloride 80 meq twice a day social history: former smoker. physical examination: vital signs: temperature 97.6, blood pressure 102/64, heart rate 86, respiratory rate 16, oxygen saturation 100% on room air. the patient appeared to be a rather thin woman in no apparent distress. head, eyes, ears, nose and throat examination within normal limits. cardiovascular examination regular rate and rhythm, ii/vi systolic ejection murmur, soft heart sounds. chest: good inspiratory effort, clear to auscultation bilaterally, occasional crackles bibasilarly. abdominal examination: bowel sounds present, abdomen soft, nontender, nondistended. extremities: bilateral pitting edema, extremities otherwise warm and well perfused, no pulses palpable secondary to edema. laboratory data: hematocrit 29.9, white blood cell count 9.2. pt 13.9, ptt 150. glucose 90, bun 56, creatinine 1.8, potassium 4.4. an electrocardiogram obtained on showed a probable accelerated junctional rhythm. hospital course: the patient was originally admitted to the medicine service. she was placed on intravenous heparin. she was continued on amiodarone. the patient was also started on amoxicillin for endocarditis prophylaxis. the patient was transfused with two units of packed red blood cells. the patient was diuresed. at the time, cardiac surgery was consulted about a possible surgical intervention, given valvular disease. on , the patient underwent tricuspid valve repair (#32 annuloplasty ring) and mitral valve repair (#29 st. mechanical valve). the procedure was without any complications. please see the full operative note for details. the patient was transferred to the intensive care unit in stable condition. the patient continued to be in accelerated junctional rhythm. no ectopy was noted. electrophysiology service was consulted. their opinion was that both the a and the v leads were malfunctioning. the patient was extubated on postoperative day one. the patient tolerated extubation well. physical therapy was consulted to follow the patient throughout the hospitalization. the chest tubes and the urine catheter were removed. the patient was continued on intravenous heparin and she was also given a dose of coumadin on postoperative day three. electrophysiology service was following the patient throughout the hospitalization. the patient's pacemaker was re-interrogated on postoperative day four. their opinion was that the pacing leads are not functioning well, but overall system is adequate with vvi pacing. they thought that lead revision would very likely be a long procedure without guarantee of improving quality of right atrial or right ventricular leads. given the fact that the patient is not pacemaker dependent, the decision was made to not proceed with lead revision but to follow the patient clinically. the patient was also seen in-house by the congestive heart failure attending, who recommended changes to the diuresis regimen. the patient continued to do well. she continued to be in junctional rhythm with some ectopy. on , the patient had one run of ventricular tachycardia (four beats), which was not repeated. in addition, the patient's potassium level was measured at 2.1. it was adequately replenished with oral and intravenous potassium at the time. the patient's repeat potassium was stable at 4.2. the patient was discharged to a rehabilitation facility on in stable condition. condition on discharge: good discharge disposition: rehabilitation facility discharge diagnosis: 1. valvular disease status post mitral valve repair and tricuspid valve repair 2. congestive heart failure 3. atrial fibrillation 4. cardiomyopathy 5. hypertension 6. chronic renal insufficiency 7. anemia discharge medications: 1. lisinopril 5 mg once daily 2. lasix 80 mg twice a day 3. potassium chloride 20 mg twice a day 4. amiodarone 200 mg once daily 5. metoprolol 12.5 mg twice a day 6. metolazone 5 mg once daily 7. fioricet one to two tablets every four hours as needed 8. clonazepam 0.5 mg by mouth three times a day 9. fluoxetine 80 mg by mouth once daily 10. ursodiol 300 mg by mouth twice a day 11. synthroid 12.5 mcg by mouth once daily 12. colace 100 mg by mouth twice a day 13. ranitidine 150 mg by mouth twice a day 14. coumadin to be adjusted to the inr goal of 2.5 to 3.0 15. ambien 5 mg daily at bedtime as needed discharge instructions: 1. the patient is to follow up with her surgeon, dr. , in approximately four weeks. 2. the patient is to follow up with (the congestive heart failure specialist) in approximately one week. 3. the patient is to follow up with her primary care physician within the next one to two weeks. 4. anticoagulation instructions: the patient's coumadin level is to be adjusted accordingly to maintain an inr level of 2.5 to 3.0. , m.d. dictated by: medquist36 procedure: extracorporeal circulation auxiliary to open heart surgery diagnostic ultrasound of heart other esophagoscopy open and other replacement of
