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: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: left sided weakness major surgical or invasive procedure: iv t-pa history of present illness: 71 year old rh man with history of atrial fibrillation, hypertension, and cad who presents with acute onset of left sided weakness at 10:30 pm yesterday. his wife was with him in the living room when she noticed acute onset of left side facial droop. she then tried to get him up but he fell over due to left arm/leg weakness. he then complained that he had a headache and felt dizzy. his wife gave him 5 mg coumadin but when he did not feel better, she called ems. he was taking coumadin but then stopped it 3 days ago for a tooth extraction yesterday morning. past medical history: atrial fibrillation cad htn lupus chf gi bleed fe deficiency social history: he is an owner of a printing shop who lives with wife. no tobacco, occasional etoh, no ivdu. physical exam: mental status: awake and alert, cooperative with exam, normal affect orientation: oriented to person, place language: fluent with good comprehension and repetition;

no carotid stenosis echo: the left atrium is moderately dilated. the right atrium is moderately dilated. no atrial septal defect is seen by 2d or color doppler. there is moderate symmetric left ventricular hypertrophy. the left ventricular cavity size is normal. overall left ventricular systolic function is normal (lvef 70%). right ventricular chamber size and free wall motion are normal. the ascending aorta is moderately dilated. the aortic arch is mildly dilated. there are focal calcifications in the aortic arch. the aortic valve leaflets (3) are mildly thickened but aortic stenosis is not present. the mitral valve leaflets are mildly thickened. there is no mitral valve prolapse. mild (1+) mitral regurgitation is seen. there is borderline pulmonary artery systolic hypertension. there is no pericardial effusion. brief hospital course: pt was found to have a right mca stroke (cardioembolic in setting of stopping coumadin for dental procedure) and was given iv-tpa in the er and admitted to the neurology service. he was registered at at 0015. labs were drawn at 0025 and his inr was 1.2. ct scan at 0050 showed a dense rt mca, loss of the insular ribbon and grey white junction elsewhere in the rtmca territory. exam at that time was reported to show a nihscale of 16 primarily due to left sided weakness, sensory deficit and neglect. he recieved a bolus of 8.2 mg iv tpa at 0135. the rest of the 73.6 mg was given as a drip. he was admitted to the n-icu for observation, neuro checks and bp montioring. post-t-pa course was complicated by dental bleeding (s/p extraction) which resolved spontaneously. he had a cta and rpt ct post iv t- showed patenet proximal right mca with decreased mca branching. ct also showed petechial hemorrhage within infarct. he was started on aspirin . because of the small hemorrhage seen on follow up ct, his coumadin should be held for one week and restarted on . he should continue to take asa until his inr is therapeutic. echo showed no evidence of intracardiac thrombus. carotid duplex showed patenet carotids. his blood pressure was initially controlled with labetalol drip which was converted to oral metoprolol. acei was added for improved bp control. on he had an episode of rapid afib which responded to diltiazem, metoprolol dose was increased for better rate control with good results. on he was found to have a uti and left ll pna. he was started on levoquin and has remained afebrile. he had a video swallow evaluation on . diet recommendations for pureed solids, nectar thick liquids. maintain aspiration precautions, alternate between taking bites and sips. he was seen be pt and ot during his admission and was felt to be an excellent candidate for rehab. he is now being discharged to acute rehab facility for continued care. medications on admission: verapamil 360 lopressor 100 coumadin 2.5-not taking for dental procedure ativan 2 folate discharge medications: 1. aspirin 325 mg tablet sig: one (1) tablet po daily (daily). tablet(s) 2. lisinopril 5 mg tablet sig: one (1) tablet po daily (daily). 3. atorvastatin calcium 10 mg tablet sig: one (1) tablet po hs (at bedtime). 4. metoprolol tartrate 50 mg tablet sig: one (1) tablet po bid (2 times a day). 5. protonix 40 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po once a day. disp:*30 tablet, delayed release (e.c.)(s)* refills:*2* 6. levofloxacin 500 mg tablet sig: one (1) tablet po once a day for 7 days. discharge disposition: extended care facility: - discharge diagnosis: right mca stroke discharge condition: improved: left hemiparesis, improving discharge instructions: please keep appointments as outlined below. you should resume taking coumadin on . please follow up with your primary care doctor to have your inr monitored after re-starting coumadin. you should continue to take aspirin until your inr is therapeutic. please return to the emergency room for worsening visual symptoms, weakness, numbness, or any other worrisome symptoms. followup instructions: 1. clinic: dr. call to make an appointment 2. pcp: . follow up with after discharge from rehab md, procedure: injection or infusion of thrombolytic agent diagnoses: pneumonia, organism unspecified systemic lupus erythematosus coronary atherosclerosis of native coronary artery urinary tract infection, site not specified unspecified essential hypertension atrial fibrillation other postprocedural status cerebral embolism with cerebral infarction acquired absence of teeth, unspecified hemiplegia, unspecified, affecting nondominant side
