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 81 year-old gentleman with recent revision of ventriculoperitoneal shunt for development of chronic subdural hematoma. the patient was discharged to rehabilitation on on a heparin drip and coumadin for his st. jude's valve. the patient was doing well at rehabilitation until the evening of when he was noted to be decreased mental status and lethargic. the patient was transferred to the for evaluation. pressure was 193/62, heart rate 58, saturations 97 percents. his eyes were closed and did not open to stimuli. responded to grimacing with limited verbal output. withdrawal of all extremities to pain, right greater than left. following commands in the right upper extremity, squeezing, withdrawing bilateral lower extremities. the pupils 3 to 2 mm and reactive. face was symmetric. the incision was clean, dry and intact. a ct showed a large right interparenchymal hemorrhage with clot casting the right lateral third ventricle and extending into the left lateral ventricle with acute hemorrhage in the chronic subdural hematoma which was larger than when he was discharged. hospital course: the patient was admitted to the intensive care unit and a vent drain placed at the bedside. the patient was monitored with q1 hour neural checks. he was opening his eyes to void, oriented to name, and . the patient had a left facial droop. grips were full bilaterally and his ipa's were full. the patient was seen by cardiology in regards to his st. jude valve and anticoagulation. the patient was taken off anticoagulation and cardiology recommended restarting it as soon as possible when safe from a neurologic standpoint. the patient was restarted on coumadin on . on the patient was awake, alert and extraocular motions were full. the patient continued to have a left facial droop. grasps were full bilaterally. his ip's were antigravity. the patient had some difficulty following commands. the patient remained neurological stable and his drain was increased to 15 cm above the tragus. the patient was transfused with two units of packed cells for a hematocrit of 25.3. his mental status deteriorated with a drain at 15 cm above. the drain was put back down to 10 cm above the tragus. the patient had an echocardiogram on that showed dilated left atrium and an ejection fraction of less than 20 percent. ct on showed decrease in the amount of hemorrhage in the ventricles. the size of the ventricles was decreased. on a vent drain was titrated to keep the drain output 10 to 15 cc an hour. the patient's mental status improved. a head ct on showed no interval change. on the patient was awake and conversing and squeezing on the right, withdrawing his lower extremities bilaterally. chest x-ray on showed left lower lobe pleural effusion. on the vent drain was clamped. the patient continued to require q1 hour neural checks. the patient tolerated having the vent drain clamped and it was discontinued on . the patient was neurological stable and was awake, alert and oriented times two. the pupils are equal, round, and reactive to light and accommodation. the patient continued to have left facial droop and left drift. his strength on the right side was . the patient was followed by physical therapy and occupational therapy and found to require acute rehabilitation prior to discharge to home. his vital signs were stable. the patient was neurologically awake, alert and oriented times two with continued right sided weakness with the left side moving spontaneously and strongly. vent drain stitch will be removed in five days on . the patient was tolerating a diabetic soft diet with thickened liquids. the patient's condition was stable at the time of discharge. the patient will follow up with dr. in two weeks for a repeat head ct. should continue on coumadin 10 mg p.o. day to keep his inr 2.5 to 3. discharge medications: metoprolol 150 mg p.o. t.i.d., hold for systolic pressure less than 110, heart rate less than 60. captopril 75 mg p.o. t.i.d, hold for systolic pressure of less than 110. colace 100 mg p.o. b.i.d., coumadin 10 mg p.o. q day, tylenol 650 mg p.o. q4 hours p.r.n., famotidine 20 mg p.o. b.i.d., insulin sliding scale both fixed and sliding scale. fixed is nph 18 units in the morning and 14 units at bedtime covered by sliding scale. folic acid 1 mg p.o. q day. ferrous sulfate 325 mg p.o. q day. heparin 5000 units subcutaneously q12 hours. condition: the patient's condition is stable. follow up: the patient tolerated the procedure well is to follow up with dr. in two weeks with repeat head ct. , m.d. dictated by: medquist36 procedure: spinal tap incision of lung spinal tap incision of lung enteral infusion of concentrated nutritional substances intravascular imaging of intrathoracic vessels arterial catheterization transfusion of packed cells other diagnostic procedures on brain and cerebral meninges diagnoses: anemia, unspecified obstructive hydrocephalus unspecified pleural effusion congestive heart failure, unspecified atrial fibrillation intracerebral hemorrhage systolic heart failure, unspecified cardiac pacemaker in situ subdural hemorrhage
