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 an 85 year old woman with a history of hypertension, atrial fibrillation, status post a fall a month ago, admitted for one week and then discharged to rehabilitation. she was referred to the emergency room by her primary care physician for an episode of left facial weakness and decreased comprehension and speech. the patient's daughter also describes an increase in lethargy with persistent nausea and episodes of vomiting. a head ct scan in the emergency department shows an increased size of the right subdural hematoma with no acute component. on arrival the patient was awake and alert, oriented times three, complaining of nausea and vomiting. past medical history: 1. hypertension. 2. subdural hematoma a month ago. 3. heart murmur. 4. atrial fibrillation. physical examination: on physical examination, the patient was awake and alert, oriented times three, conversing appropriately. extraocular muscles are full. pupils equally round and reactive to light with right down 4 to 3 and the left 3 to 2. strength was five out of five throughout and reflexes were intact. head ct scan shows a right 2 cm subdural hematoma with no acute component but increase in size compared to head ct scan from a month prior. the patient was neurologically stable. hospital course: the patient had twist drill drainage of the subdural hematoma at the bedside without complication. the patient had just slight left facial asymmetry with no pronator drift, moving all extremities strongly. the patient also developed symptoms of transient ischemic attacks prior to admission. she had a carotid ultrasound of her neck which was clear and a transesophageal echocardiogram which revealed a left atrial appendage thrombus near the aortic arch, gradient of 2, and four plus tricuspid regurgitation. she was seen by cardiology who recommended a rate control for her atrial fibrillation. she was started on digoxin and lopressor as well as diltiazem. she will be followed up as an outpatient for treatment of the atrial thrombus as an outpatient. she will require anti-coagulation but she will not be able to receive anti-coagulation for one month. neurologically, she is awake, alert and oriented times three. no drift. face is symmetric. strength was five out of five in all muscle groups. a repeat head ct scan showed good evacuation of the subdural hematoma and the drain was removed on . she was transferred to the regular floor. carotid ultrasound of her neck did show less than 40% stenosis of the right internal carotid and 40 to 59% of the left internal carotid stenosis. the patient was seen by physical therapy and occupational therapy and found to require rehabilitation prior to discharge to home. she was discharged to rehabilitation in stable condition with follow-up with dr. in one month and also with cardiology for treatment of a left atrial thrombus. her vital signs were stable at the time of discharge. discharge medications: 1. diltiazem 180 mg p.o. q. day. 2. digoxin 0.125 mg p.o. q. day. the patient should have a level drawn and checked on . 3. metoprolol 25 mg p.o. twice a day. 4. dilantin 100 mg p.o. three times a day. 5. levobetaxolol hydrochloride 0.5%, one drop o.u. q. day. 6. sodium chloride 1 gram p.o. four times a day. 7. protonix 40 mg p.o. q. 24 hours. condition at discharge: the patient's condition was stable at the time of discharge. discharge instructions: 1. she will follow-up with dr. in one month with a repeat head ct scan. 2. she will follow-up with cardiology in one month for treatment of her left atrial thrombus. , m.d. dictated by: medquist36 procedure: incision of cerebral meninges diagnoses: congestive heart failure, unspecified unspecified essential hypertension atrial fibrillation aortic valve disorders subdural hemorrhage following injury without mention of open intracranial wound, unspecified state of consciousness fall from other slipping, tripping, or stumbling 

Answer: The patient is high likely exposed to
