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 85-year-old female with a 24-hour history of abdominal pain that started the day prior to admission. the patient also complained of urgency to defecate and nausea. the patient had emesis x 2 the night prior to admission. she felt lightheaded and had increasing abdominal pain. she was taken to hospital where she was hypotensive at the time. she was admitted to the unit. a femoral line was placed and volume resuscitation was initiated. she continued to have worsening abdominal pain this morning. past medical history: 1. coronary artery disease. 2. atrial pacer. 3. primary pulmonary hypertension. 4. ischemic heart disease. 5. atrial fibrillation. 6. hypertension. 7. gout. 8. myocardial infarction. past surgical history: open cholecystectomy. medications at home: 1. amiodarone 200 b.i.d. 2. lopressor 25 b.i.d. 3. protonix 40 q.d. 4. nitroglycerin patch 0.2 p.r.n. 5. plavix 75 q.d. 6. aspirin q.d. 7. digoxin 0.125 q.o.d. allergies: codeine causes hallucinations. physical examination: vital signs were temperature 95.3, heart rate 79, blood pressure 94/41, respiratory rate 18, 96% on two liters nasal cannula. she was on a neo-synephrine drip. her cardiovascular examination showed a paced rhythm with no murmurs, gallops, or rubs. her lung examination was clear to auscultation bilaterally. on abdominal examination the patient was distended with decreased bowel sounds. she was tender in the lower left lateral abdomen with mild tenderness in the right lower and left upper quadrants. she exhibited voluntary guarding of the left lower quadrant. there was no rebound tenderness. on rectal examination there were no masses and she was guaiac positive. her extremity examination showed no evidence of cyanosis, clubbing or edema. laboratory data: white blood cell count was 15 with 34% bands, creatinine 1.6, amylase in the 600s, lipase 15. cat scan from yesterday showed a contained perforation and mild thickening of the descending colon with stranding of the mesentery. hospital course: the patient was taken to the operating room on emergently with a preoperative diagnosis of ischemic left colon. while in the operating room the patient had a left hemicolectomy, a hartmann pouch and end ileostomy. details of the procedure can be found in the operative note. she had complete transmural necrosis of the proximal left decending colon with obvious perforation or peritonitis. the sma pulse was strong. the presumed etiology was an embolis with ischemia vs. a low flow state (less likely given strong sma pulse). while in the operating room the patient's blood pressure dropped initially. the patient was treated with increasing iv fluids, neo-synephrine drip and was transfused two units of packed red blood cells. in addition, the calcium and bicarbonate were repleted for lactic acidosis. the patient was transferred to the surgical intensive care unit postoperatively intubated and on a neo-synephrine drip. vital signs were stable when transferred to the surgical intensive care unit. while the patient was in the surgical intensive care unit, the patient was heparinized for presumed embolic event. a transesophageal echocardiogram was performed to evaluate for cardiac source of embolus. no thrombus was seen, however the echocardiogram was positive for a right-to-left shunt at rest with the bubble study, consistent with a stretched patent foramen ovale. while in the surgical intensive care unit the patient continued to be intubated until mobilizing her fluids. on postoperative day number three in the surgical intensive care unit, it was attempted to extubate the patient, but the patient started to desaturate to the 80s and so the patient was placed back on the ventilator. she was given lasix with good diuresis and staff was able to extubate the patient in the afternoon post diuresis. the patient was weaned to o2 by nasal cannula at four liters when her oxygen saturations were greater than 95% with no shortness of breath and her arterial blood gas was within normal limits. on postoperative day five the patient was tolerating clear liquids without any nausea or vomiting. her intake was greater than 400 cc p.o. that day. her colostomy stoma was pink with small round brown ischemic areas on the outer aspect. her ostomy was producing stool and the ostomy nurse replaced the appliance. the patient continued to be monitored in the surgical intensive care unit. her heparin drip was titrated accordingly. the patient continued to be hemodynamically stable and on postoperative day six the patient was transferred to the floor. while on the floor the patient continued to tolerate p.o. without difficulty. her ostomy stoma was pink, viable and showed good output. her abdominal examination continued to be soft and nontender. anticoagulation was continued as the patient was started on coumadin. heparin was discontinued when the inr was greater than 2.0. the patient's diet was advanced. she would continue to tolerate a regular diet without difficulty. physical therapy was consulted and recommended aggressive physical therapy and rehabilitation placement. the patient was discharged on postoperative day 11 with an inr of 2.0 and her last dose of coumadin prior to discharge was 0.5 mg on that day. the patient's pain was well controlled and the patient had been out of bed with physical therapy help. arrangements were made by the case manager for the patient to go to rehabilitation at and rehabilitation center in . condition on discharge: good, stable. discharge status: to rehabilitation at and rehabilitation center in , . discharge diagnoses: 1. ischemic left colon probable cause thromboembolism, status post exploratory laparotomy, left hemicolectomy, hartmann pouch, and end ileostomy. 2. coronary artery disease. 3. atrial pacing. 4. primary pulmonary hypertension. 5. ischemic heart disease. 6. atrial fibrillation. 7. hypertension. 8. gout. 9. myocardial infarction. discharge medications: 1. ostomy care. 2. amiodarone 200 mg q.d. 3. famotidine 20 mg b.i.d. 4. metoprolol tartrate 50 mg b.i.d. 5. digoxin 125 mcg q.d. 6. coumadin 0.5 mg q.d. 7. outpatient laboratory work for coumadin dosing. disposition: the patient is to go to rehabilitation and then to follow up with dr. in one to two weeks for staple removal and follow up. dr. number is included in the discharge summary. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified venous catheterization, not elsewhere classified
