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 82-year-old female with a history of cva with no residual defects, severe aortic stenosis, mild to moderate mitral stenosis who was referred to for cerebral angiography. the patient was to undergo an avr/mvr and a preop workup demonstrated conflicting information regarding her carotid disease. an ultrasound in showed an 86% rca stenosis while a subsequent ultrasound in showed a 60-79% left ica stenosis. therefore, the patient was to go on carotid catheterization today to determine the extent of her disease. the catheterization was complicated by hypertension and bradycardia status post removal of her arterial sheath for which she was given atropine, iv fluids, and dopamine. her postprocedure hematocrit was 29.3, which was decreased from 37.2 on admission. she was given 1 unit of packed red blood cells. she was transferred to the ccu for further monitoring. past medical history: 1. cva in with no residual defects. 2. severe as. 3. mild to moderate mitral stenosis. 4. hypothyroidism. 5. hypertension. 6. dyslipidemia. 7. history of colonic polyps. 8. peptic ulcer disease. 9. peripheral vascular disease. 10. history of gi bleed on plavix. allergies: she is allergic to plavix which causes a gi bleed; pravachol, which is, diarrhea; and demerol with an unknown allergy. medications on admission: 1. synthroid 100 mcg p.o. q.d. 2. norvasc 5 mg p.o. q.d. 3. toprol xl 50 mg p.o. q.d. 4. effexor 75 mg p.o. q.d. 5. zetia 10 mg p.o. q.d. 6. folgard. 7. aggrenox. 8. . 9. avalide 300/12.5 mg q.d. family history: noncontributory. social history: she is widowed and lives alone. currently, the patient denies any chest pain, shortness of breath, nausea or vomiting. she has mild abdominal pain in her left lower quadrant but otherwise no complaints. physical examination: patient was afebrile. pulse 76, blood pressure 114/45, respiratory rate 19. she was saturating 97 percent on 2 liters. pertinent exam findings are, her neck was supple. her jvd was approximately 7 cm. her lungs were clear. her heart was regular rate and rhythm. she had a grade 4/6 systolic ejection murmur heard throughout the precordium, best at the right upper sternal border. on abdominal exam, her belly was soft, normoactive bowel sounds. she had mild left lower quadrant tenderness without rebound. she had mild voluntary guarding. on extremity exam, she had no edema. she had 2 plus dorsalis pedis pulses bilaterally and pt pulses bilaterally. laboratory data: her preop hematocrit was 37.2 and as mentioned, the patient had a drop in her hematocrit to 29.3. her chem-7 was unremarkable. ct of the abdomen showed a large hematoma in the left groin which extended into the left pararenal space and up to the left renal hilum. with regard to her cerebral angiography, her left common carotid artery was normal. there was a mild osteal stenosis in the left external carotid artery. the ica was normal to the brain. the right common carotid artery was normal. there was a severe osteal external carotid artery stenosis with a calcified bulb, but the ica was normal to the brain. hospital course: she was admitted to the ccu for further monitoring. her blood pressure medications were held until the next day. she was transfused an additional unit of packed red blood cells with an appropriate response to her hematocrit. her hematocrit on the day of discharge was 35.2 and had remained stable. furthermore, her blood pressure remained stable during her hospital course. in addition, her abdominal exam on the day of discharge was stable, and she had no evidence of rebound or guarding. after discussion with the attending, it was felt that she was safe to be discharged, given her stable vital signs and hematocrit. discharge instructions: she is instructed to call her primary care provider should she develop any lightheadedness or dizziness, chest pain, shortness of breath, abdominal pain, nausea or vomiting. she was also instructed to take only her toprol xl and norvasc for now, and she was told not to take her hydrochlorothiazide or her avapro until she followed up with her primary care doctor . discharge diagnoses: 1. retroperitoneal hematoma. 2. hypertension. 3. depression. 4. dyslipidemia. 5. severe aortic stenosis. 6. mild to moderate mitral stenosis. 7. carotid angiography: severe osteal disease of the right external carotid artery with only mild atherosclerotic disease of both internal carotid arteries. she was instructed to follow up with dr. on at 11:30 a.m. her valve replacement surgery was canceled because of her recent bleeding. major surgical/invasive procedures: carotid catheterization/angiography. discharge medications: 1. t4 100 mcg p.o. q.d. 2. toprol xl 50 mg p.o. q.d. 3. she was told to hold her hydrochlorothiazide. 4. effexor 75 mg p.o. q.d. 5. norvasc 5 mg p.o. q.d. she was told not to take this medicine until she followed up with her pcp. 6. irbesartan 300 mg. she was told not to take this until she followed up with her primary care doctor. 7. 60 mg p.o. q.d. 8. multivitamin 1 tablet p.o. q.d. 9. aggrenox 200/25 mg. she was instructed not to take this until she followed up with her pcp, it could cause bleeding. 10. she was also discharged on aspirin 81 mg p.o. q.d. however again, she was told not to take this until she followed up with her primary care doctor. , procedure: arteriography of cerebral arteries transfusion of packed cells diagnoses: other iatrogenic hypotension pure hypercholesterolemia unspecified essential hypertension unspecified acquired hypothyroidism hemorrhage complicating a procedure other specified procedures as the cause of abnormal reaction of patient, or of later complication, without mention of misadventure at time of procedure mitral valve insufficiency and aortic valve stenosis occlusion and stenosis of multiple and bilateral precerebral arteries without mention of cerebral infarction unspecified late effects of cerebrovascular disease 

Answer: The patient is high likely exposed to
