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 a 71-year-old man with a history of hypertension and hypercholesterolemia who was diagnosed with carotid artery disease in after an episode of dizziness. he has been followed since by serial ultrasounds, the most recent of which showed a right velocity of 429 cm per second with an ic to cca ratio of 4.6 and a left-sided velocity of 107 cm per second with a ratio of 1:1. on a carotid ultrasound showed an 80-99% right ica occlusion. on mr of the carotids showed a 95% right ica lesion with no significant left-sided stenosis. the patient presented for carotid catheterization. a stent was placed in the right internal carotid artery with 20% residual stenosis. the patient was transferred to the coronary care unit for further monitoring. he denied vision changes, paresthesias, chest pain, shortness of breath, dizziness, nausea or vomiting, or pain. he denied any history of claudication, orthopnea, edema, paroxysmal nocturnal dyspnea, lightheadedness, amaurosis fugax. he denied any focal neurological signs. he has had normal bowel habits, no bright red blood per rectum, no melena, no gastroesophageal reflux disease. past medical history: no history of coronary artery disease, transient ischemic attack, or cerebrovascular accident. he further denied any history of hypertension. he admitted to: 1. hypercholesterolemia. 2. peripheral vascular disease. 3. mastoid surgery. medications at home: 1. aspirin 325 mg q. day. 2. plavix 75 mg q. day. 3. lorazepam 0.5 mg q.a.m. p.r.n. 4. lipitor 20 mg q.h.s. 5. vitamin c. 6. vitamin e. 7. dhea. family history: his father died of heart disease at age 68. social history: the patient is widowed and lives alone. he is a retired electrical engineer. he denied any use of alcohol, denied any use of tobacco, and reports a remote cigar history. he denied any use of illicit drugs. physical examination: vital signs were 97.8, heart rate 62, blood pressure 160/80, respiratory rate 18, 99% saturation on room air. he was laying flat with oxygen on nasal cannula at two liters with no apparent distress. heent: anicteric, moist mucous membranes, no jugular venous distension, and a positive right carotid bruit. cardiovascular: his point of maximal impulse was not palpable. he had a regular rate and rhythm, normal s1 and s2, no murmurs, gallops, or rubs. radial, dorsalis pedis and posterior tibial pulses were 2+ bilaterally and equal. lungs: clear to auscultation anteriorly. abdomen: soft, nontender, nondistended, positive bowel sounds, with a questionable left renal bruit. extremities: warm and dry with no edema. the right femoral sheath site was without hematoma or bruit. it was clean, dry and intact with minimal oozing. neurological: cranial nerves ii-xii were intact. sensation was intact in the upper and lower extremities bilaterally and across the face. motor was intact in the upper and lower extremities bilaterally and equal. laboratory data: the patient had no laboratory abnormalities. ekg showed a normal sinus rhythm with a normal axis, good r waves across the precordium. hospital course: overall this was a 71-year-old man status post a right internal carotid artery stent for artery disease. he was to continue his aspirin, his lipitor and his plavix, to monitor his neurological signs and symptoms every four hours for post procedure transient ischemic attacks and cerebrovascular accidents, to continue plavix and aspirin for nine months, to maintain a systolic blood pressure during the first week postoperative of 140-170 systolic, to sustain coronary cerebral perfusion. rhythm was normal sinus. he was monitored on telemetry for bradycardias or vagal symptoms post procedure, but this did not happen. 1. pump: his ejection fraction was unknown, no clinical evidence for congestive heart failure. oxygen was weaned. the patient no longer required oxygen for ambulation to maintain saturations in the high 90s. the patient tolerated a regular diet. fluid and electrolytes were monitored and repleted. 2. hematology: there was no postprocedure blood loss. his hematocrits were stable throughout his hospitalization. his pulses were strong. the patient had a neurology consultation who found the patient to be neurologically intact, hemodynamically stable. a homocystine level was checked but was pending at the time of discharge. he denied any changes in vision, nausea, vomiting, shortness of breath, or pain during the course of the hospitalization. telemetry monitoring across the hospitalization showed no ectopy. disposition: the patient was discharged in stable condition feeling well. follow-up plans: the patient was instructed to follow up with dr. in clinic in the next two weeks for blood pressure monitoring as well as to monitor the stent placement. discharge medications: 1. plavix 75 mg q. day. 2. aspirin 325 mg q. day. 3. lipitor 20 mg q. day. 4. ativan 0.5 mg q.a.m. p.r.n. 5. vitamin e. 6. vitamin c. , m.d. dictated by: medquist36 procedure: angioplasty of other non-coronary vessel(s) insertion of non-drug-eluting peripheral (non-coronary) vessel stent(s) diagnoses: pure hypercholesterolemia peripheral vascular disease, unspecified occlusion and stenosis of carotid artery without mention of cerebral infarction 

Answer: The patient is high likely exposed to
