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 89 year old right-handed man with a history of questionable hypertension, hypercholesterolemia, aortic aneurysm and prostate cancer who was in general good health when he got up and went to the left arm and leg weakness in the bathroom at 07:05. this made him fall. ems came by 07:30 and he was brought to at 08:45. was proptly evaluated by dr from the stroke team, mri confirmed the diagnosis of stroke and since he met the ninds criteria, he was treated with iv 0.9 mg/kg of iv tpa. the patient had an initial improvrment of his symptoms and recovered his deficit physical examination: on arrival, blood pressure 134/80; heart rate 80. chest clear bilaterally. cardiovascular: regular rate and rhythm, no murmurs, no bruits. abdomen soft, nontender, nondistended. extremities with no cyanosis, clubbing or edema. neurologic: alert and oriented times three. attention and memory intact. no dysarthria. no aphasia. "my left arm and leg are weak" is what the patient said. can repeat no ifs, ands or buts. makes jokes appropriate. cranial nerves: pupils equal and reactive. extraocular movements are intact. i through iii intact. mild left nasolabial fold decrease. uvula, tongue midline. no sternocleidomastoid on the left. motor examination: no movement in the left upper and lower extremities. five out of five on the right. finger-to-nose, heel-to-shin, no ataxia on the right. sensory symmetric to light touch and pinprick. no extinction to double simultaneous stimulation. no extinction in his visual fields. laboratory: an mri showed an area of restricted diffusion in the right aca territory. mra shows no flow in the right ica, right middle cerebral artery, right aca likely secondary to low flow state. the patient had labs done at that time pre-tpa. white count of 4.3, hematocrit of 40, platelets 132,000. pt 11.9, ptt 25.4, inr 1.0. electrolytes showed a potassium of 7.4, otherwise normal. calcium, magnesium and phosphorus were also normal. repeat potassium was done which came out at 8.6 and was grossly hemolyzed. he had another repeat potassium 20 minutes after that which showed a potassium of 4.2. hospital course: blood pressure was controlled with a labetalol drip and following tpa, mr. actually did well. however, later that same day, six hours after tpa it was noted that he had decreased movement in the left leg. he was taken emergently for an angiogram that showed a 99% right ica stenosis. after a long discussion with dr from the vascular surgery team, dr form the nes/inr team and the stroke team it was deicided that it was prudent not to operate emergently and he was started on heparin. the angiogram also showed ica to eca collateralization and a large (5 cm) aaa. on day 3 of his nicu stay the patient had bleeding through his foley catheter, thus the heparin was stopped. urology was consulted who inserted a foley catheter and started a three-way irrigation. fenestram and flomax was started and levaquin was started for a presumptive urinary tract infection. a follow-up ct scan was obtained to evaluate the abdominal aortic aneurysm which showed that it was stable without dissection, which is the final read. vascular surgery at that point, decided that the patient should not be anti-coagulated on coumadin long- term prior to repair of the abdominal aortic aneurysm. the foley catheter irrigation continued through . in addition, a transesophageal echocardiogram was considered, but since vascular surgery requested no anti-coagulation on the patient, no change in therapy would result from getting the test so we deferred the transesophageal echocardiogram. the patient was transferred out to the floor on . on the floor, it was noted that his left arm became weaker. the patient's head was put down to flat and he was given intravenous hydration. at that point, movement in his arm came back. the head of his bed was raised slowly, gradually, over three or four days, about 15 degrees a day, until the patient was able to tolerate sitting up and getting out of bed without loss of function of his arm. he was also cleared by orl and swallowing. he remained somewhat confused because it is likely that his urinary tract infection had not cleared and physical therapy and occupational therapy recommended placement at rehabilitation. discharge diagnoses: 1. right internal carotid artery occlusion. 2. right anterior cerebral artery territory infarction. 3. abdominal aortic aneurysm. discharge medications: 1. flomax 0.4 mg p.o. q. a.m. 2. fenestram 5 mg p.o. q. day. 3. levofloxacin 250 mg p.o. q. p.m. times seven days. follow-up on a urine culture. 4. heparin 5000 units subcutaneously twice a day. 5. protonix 40 mg p.o. q. day. 6. levothyroxine 0.5 mg p.o. q. day. 7. lopressor 25 mg p.o. twice a day; hold for systolic blood pressure of less than 140. 8. colace 100 mg p.o. twice a day. 9. senna one p.o. q. day. 10. aspirin 325 mg p.o. q. day. 11. lactulose 30 cc p.o. q. 24 p.r.n. 12. baby aspirin. 13. . discharge instructions: 1. he will follow-up with dr. for his abdominal aortic aneurysm in one month. 2. he will follow-up with stroke team, phone number . , m.d. dictated by: medquist36 d: 10:10 t: 10:27 job#: procedure: arteriography of cerebral arteries diagnoses: pure hypercholesterolemia urinary tract infection, site not specified unspecified essential hypertension unspecified acquired hypothyroidism abdominal aneurysm without mention of rupture hemiplegia, unspecified, affecting unspecified side occlusion and stenosis of carotid artery with cerebral infarction 

Answer: The patient is high likely exposed to
