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 russian speaking male with a history of diabetes, coronary artery disease and cardiomyopathy who presented with bright red blood per rectum upon waking from sleep at 1:30 a.m. on the morning of admission. he denied any belly pain or diarrhea. he had no previous history of a gi bleed. he does endorse a history of constipation. there is a question of a history of a colonoscopy in the past, but this is remote. he was evaluated in the emergency room where he received 2 units of fresh frozen platelets for an inr of 2.9 as well as 10 mg of vitamin k. he was also transfused with 2 units of packed red blood cells for a hematocrit of 29.7. he was also given an nasogastric lavage, which was negative. he was admitted to the micu for 1 liter output of rectal bleeding in the emergency room. past medical history: 1. diabetes. 2. hypertension. 3. atrial fibrillation status post pacer in . 4. coronary artery disease status post myocardial infarction with a coronary artery bypass graft and a recent positive stress test per dr. . 5. hypercholesterolemia. 6. cardiomyopathy. 7. hypothyroidism. 8. benign prostatic hypertrophy. medications on admission: 1. coumadin 5 mg po q day. 2. cozaar 50 mg po q day. 3. glyburide 5 mg po b.i.d. 4. glyset 25 mg po t.i.d. 5. lanoxin 0.125 mg po q.d. 6. lopresor 50 mg po b.i.d. 7. multivitamin one cap a day. 8. pravachol 20 mg po q day. 9. proscar 5 mg po q.d. 10. vitamin b-1 100 mg po q.d. 11. senotab 8.6 mg po q.d. 12. lasix 120 mg po b.i.d. 13. terazosin 5 mg po q.d. allergies: no known drug allergies. physical examination on presentation to the micu: temperature afebrile. blood pressure 143/63. pulse 69. respirations 18. 99% on room air. in general, he was a pleasant russian speaking male lying in bed in no acute distress. heent examination pupils are equal, round and reactive to light. mucous membranes are moist. no carotid bruits. heart was irregular irregular with a grade 2 out of 6 systolic ejection murmur. lungs revealed mild crackles at the right base. the abdomen was soft, nontender, nondistended with positive bowel sounds. extremities were warm with weak dorsalis pedis pulses bilaterally, but positive radial and femoral pulses. neurological examination revealed the patient to be alert and oriented and communicating with russian staff fluently. laboratories on presentation: white blood cell count 7.4, hematocrit 29.7, mcv 82, platelets 179. his baseline hematocrit is known to be 33 to 36%. his inr was 2.9. his chem 7 is remarkable for a bun of 84 and a creatinine of 2.1 and a glucose of 391. hospital course: 1. gastrointestinal bleed: he was initially admitted to the intensive care unit for large rectal bleeding output. his nasogastric lavage was negative. he was transfused as mentioned above and was seen by the gastroenterology team. he had also been seen by the surgery team as well. the results of an early nuclear scan for bleeding showed findings consistent with a cecal bleed. he was sent to interventional radiology for further diagnostic evaluation for localizing the site of the bleed and had a selective mesenteric angiogram. the patient was found to have active bleeding from the branch of the ileocolic artery, which was selectively embolized with four 2 mm by 2 cm coils with cessation of active extravasation of contrast. he was transfused 2 more units to support his anemia to a hematocrit of 25% and was called out to the floor when his bleeding stabilized. he was also seen by surgery who was concerned for ischemia of the embolized segment. for this reason the gastroenterology team also agreed that a colonoscopy would place the patient at a higher risk for perforation of the segment of the colon, which was effaced by ileocolic artery embolization. by he had received 11 units of packed red blood cells and the patient was called out to the floor. he remained stable in terms of his bleeding. he did endorse a couple of episodes of small dark spotted blood with his bowel movements, but none of these resulted in a drop in his hematocrit. 2. coronary artery disease: the patient was seen by dr. in who had the patient go for a nuclear stress test, which revealed a moderate reversible perfusion defect in the anterior wall and anterior portion of the apex that was consistent with stress induced ischemia. he was held off his aspirin until his hematocrit stabilized and then restated on a baby aspirin. dr. saw the patient while he was in house, recommending that the patient have his acute gi issues settle out before doing a cardiac catheterization at the end of . he did not complain of any active chest pain. 3. congestive heart failure: the patient continued to do well from a congestive heart failure point of view. he had his lasix dose held and then reduced and appeared to do well on the reduced dose of 60 mg po b.i.d. 4. atrial fibrillation: the patient was held off his coumadin for gastrointestinal bleeding. he also had his pacemaker interrogated after having bradycardia down to the 30s one evening without pacemaker capturing. the electrophysiology team interrogated the patient and found that the pacemaker's battery had about a four month life left in the battery. they adjusted the setting and recommended that his batter be changed in two to three months time. at this time the patient is scheduled to have both his cardiac catheterization and pacemaker battery changed on admission to the hospital on . 5. benign prostatic hypertrophy: the patient was continued on terazosin and finasteride. 6. hypothyroidism: he was known to have a normal tsh on the last check. this was recommended to be followed up was an outpatient. 7. diabetes: the patient was continued on regular insulin sliding scale instead of his oral hypoglycemics due to his diet changes in preparation for procedures. discharge condition: good. discharge status: to home with vna services. discharge medications: 1. digoxin 125 micrograms po q day. 2. pravachol 20 mg po q day. 3. finasteride 5 mg po q day. 4. multivitamins one cap po q day. 5. losartan 50 mg po q.d. 6. furosemide 60 mg po b.i.d. 7. pantoprazole 40 mg po q day. 8. metoprolol 50 mg po b.i.d. 9. aspirin 81 mg po q day. 10. docusate sodium 100 mg po b.i.d. 11. glyburide 5 mg po q day b.i.d. 12. glyset 25 mg po t.i.d. 13. terazosin 5 mg po q.d. discharge diagnoses: 1. diabetes. 2. hypertension. 3. atrial fibrillation with pacemaker. 4. coronary artery disease with a history of coronary artery bypass graft in myocardial infarction. 5. hypercholesterolemia. 6. ischemic cardiomyopathy. 7. hypothyroidism. 8. benign prostatic hypertrophy. 9. acute blood loss anemia from gastrointestinal bleeding, status post ileocecal artery branch embolization in . follow up plans: the patient is to follow up with dr. on admission to the hospital on for cardiac catheterization and pacemaker battery change. in addition, he may be evaluated for automatic implanted cardioverter defibrillator at that time. he is also to follow up in heart failure clinic on at 1:30 p.m. with dr. . also he will have his creatinine checked on friday by the and the results of which will be faxed to dr. to ensure that his creatinine does not continue to rise upon discharge. also he will have laboratories drawn on , which will be faxed to the cardiac catheterization service in preparation for cardiac catheterization. , m.d. dictated by: medquist36 procedure: injection or infusion of other therapeutic or prophylactic substance arteriography of other intra-abdominal arteries other irrigation of (naso-)gastric tube diagnoses: other primary cardiomyopathies abnormal coagulation profile congestive heart failure, unspecified acute posthemorrhagic anemia diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled atrial fibrillation hypotension, unspecified hemorrhage of gastrointestinal tract, unspecified fitting and adjustment of cardiac pacemaker
