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: this is an 87 year old woman with a history of methicillin resistant staphylococcus aureus urinary tract infection, history of aspiration, status post coronary artery bypass graft, who is a nursing home patient with a recent admission for presumed urosepsis roughly one and one half weeks ago. the patient was admitted under the sepsis protocol and treated with vancomycin once culture data from her nursing home grew methicillin resistant staphylococcus aureus in her urine. the patient defervesced and was discharged home on levofloxacin. two days after her discharge, the patient started to develop nausea and vomiting and abdominal pains. the patient also noted a productive cough of white sputum. at her nursing home, the patient was found to have desaturated to 82% in room air and was transferred to the emergency department at . on arrival, the patient was normotensive, in atrial fibrillation with a ventricular rate of 150 and temperature of 103.8. the patient later became hypotensive, systolic blood pressure in the 70s, requiring fluid resuscitation. the patient was given 1.5 liters of normal saline, one gram of vancomycin, 500 mg of levofloxacin and 500 mg metronidazole in the emergency department. the patient was initially started on levophed and dobutamine drips for hypotension. the patient was subsequently transferred to the . past medical history: 1. history of falls thought to multifactorial. 2. hypertension. 3. cerebrovascular accident in , small cerebrovascular accident or transient ischemic attack in . 4. left hemianopsia. 5. coronary artery bypass graft with a porcine aortic valve replacement in , and the patient is currently on coumadin. 6. degenerative joint disease. 7. total hip replacement . 8. cataract surgery. 9. congestive heart failure with questionable diastolic heart failure, echocardiogram in , showing an ejection fraction greater than 65% with a 2.0 centimeter atrial myxoma, symmetric left ventricular hypertrophy, mild dilation of the left atrium. 10. history of paroxysmal atrial fibrillation. 11. methicillin resistant staphylococcus aureus urinary tract infection in . 12. questionable aspiration pneumonia in the past. 13. total abdominal hysterectomy. 14. appendectomy. 15. hemorrhoidectomy. 16. colonic polypectomy. allergies: sulfa. medications on admission: 1. artificial tears. 2. detrol 1 mg twice a day. 3. coumadin 2 mg q.h.s. 4. levofloxacin 250 mg once daily. 5. protonix 40 mg p.o. once daily. 6. zoloft 75 mg p.o. once daily. 7. aspirin 81 mg p.o. once daily. 8, multivitamin. 9. lopressor 25 mg twice a day. 10. fluticasone. 11. colace 100 mg once daily. 12. fosamax 70 mg q.friday. 13. albuterol and atrovent nebulizer every six hours. 14. lipitor 10 mg once daily. 15. calcium 500 mg twice a day. 16. senna twice a day. 17. iron sulfate 325 mg once daily. social history: the patient is a resident at home. she is dnr/dni but pressors are ok. physical examination: on admission, temperature was 99.4, pulse 117, blood pressure 98/45, currently on levophed, respiratory rate 24, oxygen saturation 96% on two liters of nasal cannula. her cvp is 10. on general examination, she is in no acute distress, awake, alert and oriented and responsive. the pupils are equal, round, and reactive to light and accommodation. mucous membranes are dry. on lung examination, she has crackles one third up bilaterally without any evidence of wheezing. heart examination is irregularly irregular, tachycardic. abdominal examination is soft, nontender, nondistended. extremities show no pedal edema and no cyanosis with occasional ecchymosis. neurologic examination - the patient is alert and oriented times three, grossly intact. laboratory data: on admission, urinalysis was negative for evidence of infection, less than one bacteria, no leukocyte esterase, negative white blood cells. white blood cell count on admission was 16.2, with 17 bands. chest x-ray showed no evidence of infiltrates but bilateral basilar atelectasis. electrocardiogram showed atrial fibrillation at a rate of roughly 120s. hospital course: the patient was admitted to the intensive care unit under the sepsis protocol. the patient was given aggressive fluid resuscitation and required levophed pressor for her hypotension. the dobutamine drip initially was weaned off as the patient was tachycardic. the patient was initially febrile. the source was unclear but thought to be partially treated methicillin resistant staphylococcus aureus urinary tract infection and the possibility of tracheobronchitis/pneumonia. the patient was initially placed on vancomycin and imipenem for broad spectrum coverage given that her blood pressure was low and appeared to be septic. the patient was pancultured. blood cultures grew coagulase negative staphylococcus aureus in two out of four bottles. urine culture was negative. sputum cultures were inconclusive. the patient was later switched to , tazobactam and vancomycin antibiotics for coverage. the patient had defervesced soon after antibiotic administration. echocardiogram was performed to visualize evidence of vegetation and signs of endocarditis. the transthoracic echocardiogram did not show evidence of vegetations. the patient was tachycardic during hospital course with heart rates into the 120s with evidence of heart failure. based on prior echocardiograms, the patient had diastolic heart dysfunction. controlling the rate was difficult as the patient was hypotensive. she was started on digoxin. she was loaded and given daily doses of digoxin with better rate control. the patient was also diuresed slightly with lasix given that she had mild oxygen requirement and evidence of pulmonary edema. for the patient's atrial fibrillation, she was continued on coumadin and her coagulation was monitored daily. once tachycardia was improved, blood pressure became normal and the patient was weaned off levophed pressor. the patient maintained good urine output and mentation during her hospital course. at the time of dictation, the patient was being transferred to a medical floor. please see discharge addendum for further details of hospital course. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified diagnoses: congestive heart failure, unspecified atrial fibrillation acute on chronic diastolic heart failure methicillin susceptible staphylococcus aureus septicemia pneumonitis due to inhalation of food or vomitus septic shock methicillin susceptible pneumonia due to staphylococcus aureus heart valve replaced by transplant 

Answer: The patient is high likely exposed to
