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 the present illness: this 88-year-old woman was admitted after a pericardial drain placement for pericardial tamponade. she has a past medical history significant for hypertension and stroke. she developed dyspnea and weakness at home approximately one week ago. she presented to where she was found to be in atrial fibrillation. she was rate controlled, anticoagulated, and sent home on . today, she had persistent shortness of breath and weakness at home and returned to , where a transthoracic echocardiogram revealed a large pericardial effusion with right ventricular collapse. she was subsequently transferred to for further management. on arrival, she had a blood pressure of 130/70, heart rate in the 80s, in atrial fibrillation, and a pulses paradoxus of 20-25 mmhg. she was taken to the catheterization laboratory where a pericardial drain was placed and 450 cc of serosanguinous fluid were drained. a subsequent bedside tte showed minimal residual effusion. past medical history: 1. multiple tias, stroke. 2. osteoporosis. 3. status post ovarian cyst removal. 4. status post right total knee replacement. medications at home: 1. aspirin 81 mg q.d. 2. plavix. 3. hydrochlorothiazide. 4. tums. 5. potassium. 6. multivitamin. 7. started diltiazem and coumadin last week. allergies: the patient has no known drug allergies. social history: the patient lives alone in . she quit smoking about 30 years ago after 30 pack years. she drinks alcohol occasionally. her pcp is . in . physical examination on admission: vital signs: temperature 98.0, heart rate 88, blood pressure 126/63, oxygen saturation 97% on 4 liters, normal jvp, 2+ carotid pulses, no carotid bruits. lungs: clear to auscultation anteriorly. heart: regular rate, irregularly/irregular rhythm with a friction rub and a i/vi systolic ejection murmur at the lower sternal border. abdomen: benign. extremities: with 1+ distal pulses, right groin site soft without hematoma or bruit. laboratory data on admission: significant for a white blood count 10.2, hematocrit 31.9, platelets 255,000. inr 1.3, aptt 26.4. sodium 133, potassium 3.9, chloride 91, total c02 28, bun 26, creatinine 0.9, glucose 158, ck 28, lipase 13. ekg revealed an atrial fibrillation at 96 beats per minute, normal axis, qtc 457, low voltage diffusely, with poor r wave progression. hospital course: the patient was admitted to the ccu and closely monitored after her pericardial drain placement. on , the patient was noted to have tachypnea with a respiration rate in the low 30s and a pulsus paradoxus of 16. a repeat echocardiogram was performed showing some reaccumulation of pericardial fluid as compared with a tte done about 18 hours earlier. the output of the drain remained minimal and a repeat echocardiogram done later in the day revealed interval decrease in the size of the pericardial effusion. the pericardial drain was subsequently discontinued without complications. the patient received a ct angiogram for persistent tachypnea which revealed bilateral pleural effusions but no evidence of pulmonary embolism. as the patient had a continued persistent oxygen requirement of 5 liters nasal cannula, a swan-ganz catheter was placed to assess for evidence of heart failure as a cause of hypoxemia. the pcwp was 15 to 16, and the patient was diuresed with a total of 120 mg of intravenous furosemide. her fluid balance was net 2 liters negative on . on , the patient had continued dyspnea despite the substantial diuresis. she had persistent wheezes on physical examination. the differential diagnosis for these findings was felt to include a copd flare and the patient was given 60 mg of methylprednisolone iv as well as a dose of levofloxacin. she was subsequently placed on prednisone 60 mg q.d. and salmeterol. after these interventions, the patient's breathing felt subjectively improved and her oxygen requirement decreased to the point where she had an oxygen saturation above 95% on room air. the patient remained in atrial fibrillation throughout her admission. she was continued on diltiazem, which was titrated to a dose of 90 mg q.i.d. for improved rate control. this was converted to extended-release diltiazem, and the patient was discharged on a dose of 240 mg q.d. of note, the pericardial fluid returned with an increased number of polyclonal lymphocytes. viral pericarditis was felt to be the most likely etiology of the patient's pericardial effusion. the patient was restarted on warfarin anticoagulation for her atrial fibrillation on . she was placed on a prednisone taper for her copd flare. a final echocardiogram done on revealed a loculated appearing small to moderate size pericardial effusion without any echocardiographic signs of tamponade. prior to discharge, the patient had the onset of watery stools in the setting of receiving levofloxacin for her copd exacerbation. clostridium difficile toxin was checked and returned negative. the levofloxacin was discontinued. discharge diagnosis: 1. pericardial tamponade, status post pericardiocentesis and pericardial drain placement. 2. atrial fibrillation. 3. chronic obstructive pulmonary disease exacerbation. 4. osteoporosis. discharge condition: good. discharge status: to home. discharge medications: 1. diltiazem sustained-release 240 mg q.d. 2. aspirin 81 mg q.d. 3. prednisone 40 mg for one day, 20 mg for three days, 10 mg for two days, 5 mg for two days. 4. fluticasone. 5. salmeterol. 6. albuterol. 7. atrovent. 8. warfarin 5 mg q.h.s. ,
