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 a 73-year-old female, transfer from hospital on where she presented on with nausea and vomiting, abdominal pain, and bloody diarrhea. ct scan at hospital revealed a probable superior mesenteric artery occlusion at which time the patient was transferred acutely to for assessment and treatment by the vascular surgery team. the patient began experiencing symptoms on , first starting off with lower abdominal pain, copious diarrhea and nausea and vomiting. the patient was admitted to hospital on after diarrhea became bloody in nature. at hospital the patient's abdominal pain and abdominal physical examination worsened. ct examination on revealed superior mesenteric artery occlusion at which time the patient was transferred to . at hospital the patient was also noted to have developed a new-onset atrial fibrillation, which was thought to be the source of a potential embolus to the superior mesenteric artery. past medical history: 1. hypertension. 2. hypercholesterolemia. 3. borderline diabetes mellitus. 4. status post appendectomy. 5. status post exploratory laparotomy for trauma in the past. physical examination: upon admission to the patient was noted to have regular rate and rhythm, clear to auscultation bilaterally. abdominal examination was remarkable for a very tender abdomen with positive guarding, positive rigidity and positive rebound tenderness. rectal examination was guaiac positive. extremity examination was dorsalis pedis and posterior tibial pulses palpable bilaterally. femoral pulse was palpable bilaterally. there were no carotid bruits noted. laboratory data: on admission the patient was noted to have a white count of 22, hematocrit 41.1, platelet count 273, sodium 140, potassium 3.5, chloride 108, bicarbonate 26, bun 16, creatinine 0.7, glucose 224, calcium 9.3, magnesium 2.1, phosphorous 1.1. emergency angiogram was ordered and obtained which revealed an occlusion of the superior mesenteric artery. hospital course: after the angiogram results were received the patient was taken emergently to the operating room for superior mesenteric artery thromboembolectomy. the patient was noted to have no dead or necrotic bowel at the time of exploratory laparotomy. an occlusion was noted 1-2 cm distal to the origin of the superior mesenteric artery. clot was evacuated with catheter and dacron patch was applied for closure. the patient was closed primarily with no plans for a second look operation due to strong palpable and dopplerable pulses post thromboembolectomy and a significant pinking up and reperfusion of the bowel with no areas of transmural infarction noted. the patient was discharged to the intensive care unit at this time. intensive care unit course was remarkable for continued abdominal tenderness as well as episodes of diarrhea. postoperative angiogram on showed wide patency of the superior mesenteric artery. repeat ct scan also showed widely patent mesenteric vessels with portions of bowel wall edema. at this time the patient's symptoms and radiologic findings were attributed to a reperfusion type injury. the patient's postoperative course was also significant for episodes of agitation in the intensive care unit. as the patient's abdominal symptoms and diarrhea resolved, the patient was transferred to the floor on . the patient's postoperative course on the floor was unremarkable. the patient was weaned off of tpn, started on clears, and eventually advanced to a general diet which she tolerated well. the patient is currently on a post-gastrectomy type diet of small portions of food, many meals per day. the patient was also seen by physical therapy to be evaluated for home safety. the patient was also made therapeutic on coumadin for new-onset atrial fibrillation. the patient's iv heparin was discontinued on . cardiology follow up recommended echocardiogram in one month's time prior to cardioversion attempt. until that time the patient is to remain on coumadin with a therapeutic inr between 2 and 3. the patient is currently stable, tolerating p.o. discharge status: to rehabilitation facility or to home with help from her two daughters who are nurses. discharge diagnoses: superior mesenteric artery occlusion. discharge medications: 1. pepcid 20 mg p.o. b.i.d. 2. coumadin 2.5 mg p.o. q.h.s. 3. premarin 0.625 mg p.o. q.d. 4. atorvastatin 20 mg p.o. q.d. 5. nystatin oral suspension 5 ml p.o. q.i.d. p.r.n. 6. metoprolol 25 mg p.o. b.i.d. 7. captopril 12.5 mg p.o. t.i.d. 8. miconazole powder 2% one application topically q.i.d. p.r.n. 9. clonidine tts one patch q. week. 10. albuterol inhaler 1-2 puffs q. 6 hours p.r.n. 11. tylenol 325 to 650 mg p.o. q. 4-6 hours p.r.n. 12. dilaudid 2 mg p.o. q. 2 hours p.r.n. for pain. follow-up plans: the patient is to follow up with dr. in one week. , m.d. dictated by: medquist36 procedure: parenteral infusion of concentrated nutritional substances repair of blood vessel with synthetic patch graft incision of vessel, abdominal arteries diagnoses: pure hypercholesterolemia congestive heart failure, unspecified unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled atrial fibrillation acute vascular insufficiency of intestine
