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: ms. is a 78 year-old woman with a dilated aorta to 7 cm found on routine chest x-ray. a ct scan also showed a dilated aorta. the patient was admitted for presumed ascending aortic aneurysm repair. past medical history: 1. peptic ulcer disease. 2. hypertension. 3. bilateral cataracts. 4. renal calculi. 5. obesity. medications prior to admission: 1. hydrochlorothiazide 25 mg q.d. 2. protonix 40 mg q.d. 3. multivitamin. 4. atenolol 25 mg q.d. allergies: non-steroidal anti-inflammatory drugs and aspirins both of which cause gastric upset and gastritis. also intravenous contrast, which causes chills and shaking. social history: positive tobacco use, three to five cigarettes per day. no alcohol use. carotid ultra sounds done in of this year showed no significant disease and a myoview done also in showed decreased uptake at the apex without wall motion abnormalities and an ef of 70%. physical examination: heart rate of 80 sinus, blood pressure 132/88 on the right and 122/88 on the left. height is 5'3". weight is 160 pounds. general, no acute distress. skin no obvious lesions. heent pupils are equal, round and reactive to light. extraocular movements intact. neck si supple with no jvd or bruits. chest is clear to auscultation bilaterally. cardiac is regular rate and rhythm. s1 and s2 with no murmur. abdomen is soft, nontender, nondistended. no hepatosplenomegaly. no costovertebral angle tenderness. extremities are warm and well perfuse with no clubbing, cyanosis or edema. no varicosities noted. neurological cranial nerves ii through xii intact. nonfocal examination. excellent strength in all four extremities. pulses femoral 2+ bilaterally. dorsalis pedis pulse 2+ bilaterally. posterior tibial pulse 1+ bilaterally. radial 2+ bilaterally. laboratory data: white blood cell count 10.3, hematocrit 42, platelets 314, pt 13, ptt 26, inr 1.1. sodium 135, potassium 3.1, chloride 101, co2 25, bun 27, creatinine 1.2. glucose 195, alt 8, ast 12, alkaline phosphatase 94, albumin 3.7, amylase 27. urinalysis is negative. chest x-ray shows ascending aortic aneurysm at the mid arch. hospital course: the patient was a direct admission to the operating room for presumed ________. however, a transesophageal echocardiogram done prior to preinitiation of the surgery revealed that the distal ascending arch was only 4 cm with no aortic insufficiency and an intraluminal hematoma in the distal ascending aorta with a descending aorta that had severe atheromatous disease and calcifications throughout. the decision was made at that time to cancel the surgical procedure. following which the patient was transferred to the cardiothoracic intensive care unit for recovery from anesthesia. once in the cardiothoracic intensive care unit the patient's anesthesia was reversed. she was successfully weaned from the ventilator and extubated. following extubation the patient complained of nausea and had several episodes of hematemesis with clots. an nasogastric tube was placed with a return of frank blood that we were unable to lavage to clear. gastrointestinal was called at that time following which they did an endoscopy, which showed no varices and no bleeding sites with blood in the fundus and stomach body, but no areas of active bleeding seen. following that general surgery was also consulted and the patient underwent celiac angiography, which showed no evidence of active extravasation. it did, however, show an abnormal collection of air present adjacent to the left curvature of the stomach. ct of the abdomen was done also, which showed extraluminal air medial to the esophagus at the gastroesophageal junction as well as near the lesser curvature of the stomach. the patient was brought back to the intensive care unit and followed over the next several days with serial hematocrits. she had no further episodes of hematemesis. on the following day she had a gastrograph and swallow, which was also negative and therefore a decision was made to treat the patient conservatively keeping her npo and treating her with triple antibiotics while maintaining her in the hospital for one week on total parenteral nutrition. the patient did well during that period of time and had no further episodes of hematemesis and no melena. her hematocrit remained stable. her diet was advanced slowly, starting on post tee day four from clear liquids to full liquids to soft solids to a regular diet and on hospital day ten it was decided that the patient was stable and ready to be discharged to home. at the time the patient's physical examination is as follows, temperature 98, heart rate 76 sinus rhythm, blood pressure 138/80, respiratory rate 14, o2 sat 97% on room air. weight prehospital was 86 kilograms, at discharge is 74 kilograms. laboratory data on the day of discharge white blood cell count 10, hematocrit 31, platelets 354, sodium 140, potassium 4.4, chloride 100, co2 24, bun 25, creatinine 0.9, glucose 120. physical examination neurological alert and oriented times three, moves all extremities, follows commands. respiratory clear to auscultation bilaterally. cardiac regular rate and rhythm. s1 and s2. no murmur. abdomen soft, nontender, nondistended with normoactive bowel sounds. extremities are warm and well perfuse with no clubbing, cyanosis or edema. discharge medications: 1. atenolol 25 mg q.d. 2. prilosec 40 mg q.d. 3. levofloxacin 250 mg q.d. times seven days. 4. flagyl 500 mg t.i.d. times seven days. condition on discharge: good. discharge diagnoses: 1. hypertension. 2. peptic ulcer disease. 3. bilateral cataract. 4. renal calculi. 5. ascending abdominal aortic by mri. sho be discharged to home. she is to have follow up with dr. her primary care physician in three to four weeks and follow up with dr. in his office also in three to four weeks. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere

Answer: The patient is high likely exposed to
