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: attending: chief complaint: lightheadedness, melena, episode of coffee-grounds emesis. history of present illness: this is an 83-year-old male with a history of coronary artery disease, peptic ulcer disease, congestive heart failure, and diabetes mellitus who presents with two weeks of melena and lightheadedness. five days prior to admission, the patient had an episode of coffee-grounds emesis. he also recalls some dyspnea on review of systems: review of systems reveals no chest pain, abdominal pain, dysuria, fever, chills, or sweats. he recalls a fall without loss of consciousness prior to the melena. he has had stress from his daughter's death back in . he admits to taking an aspirin per day for the past 20 years. the patient quit smoking 28 years ago with a +20-pack-year history and quit drinking 38 years ago. in the emergency department, the patient's fingerstick blood sugar levels were around the 400s, so he was given 8 units of insulin subcutaneously, 6 units of insulin intravenously, and put on a 2-units per hour insulin drip. he was also given normal saline. an order was placed for packed red blood cells because his hematocrit was 18, and gastroenterology was contact. though he was guaiac-positive, the gastric lavage revealed no blood or clots. while in the emergency department, he had electrocardiogram changes with st depressions in leads i, avl, v4, v5, and v6. therefore, the patient was given an aspirin. past medical history: (past medical history is significant for) 1. type 2 diabetes mellitus; non-insulin requiring. 2. coronary artery bypass graft in . 3. coronary artery disease with 2-vessel disease; showing right coronary artery that was stented and an occluded left circumflex artery back in . 4. hypertension. 5. hypercholesterolemia. 6. peripheral vascular disease. 7. congestive heart failure with an ejection fraction of 43% as documented on percutaneous transluminal coronary angioplasty. 8. peptic ulcer disease. 9. history of alcohol abuse. 10. cataracts. 11. glaucoma. 12. abdominal aortic aneurysm repair in . social history: the patient quit smoking 28 years ago with a +20-pack-year history. he also denies any alcohol use in the past 38 years. he lives at home alone. family history: family history is significant for diabetes mellitus, coronary artery disease, stroke, and pancreatic cancer. allergies: penicillin. medications on admission: mavik 2 mg p.o. q.d., glucophage 850 mg p.o. b.i.d., lopressor 50 mg p.o. q.d., aspirin 325 mg p.o. q.d., lipitor 10 mg p.o. q.d. physical examination on presentation: physical examination revealed his pulse upon admission was 96, blood pressure was 121/75, respiratory rate was 18, oxygen saturation was 92% on room air, temperature was 96.3. head, eyes, ears, nose, and throat revealed pupils were equal, round, and reactive to light and accommodation. extraocular movements were intact. mucous membranes were dry. the neck was supple without lymphadenopathy or jugular venous distention. cardiovascular examination revealed a regular rate and rhythm. normal first heart sound and second heart sound. a 2/6 systolic ejection murmur at the left upper sternal border without radiation. chest revealed crackles at the bases heard bilaterally. the abdomen was soft, nontender, and nondistended, with decreased bowel sounds. extremities revealed no clubbing, cyanosis, or edema were noted. he felt somewhat cool. dorsalis pedis pulses were 1+ on the right and 2+ on the left. pertinent laboratory data on presentation: laboratories upon admission revealed his white blood cell count was 22.3 (with 77% neutrophils, 3% basophils, 12% lymphocytes, 5% monocytes, 2% eosinophils). hemoglobin was 5.9, hematocrit was 18.9, mean cell volume was 89, platelets were 389. sodium was 131, potassium was 5.1, chloride was 93, bicarbonate was 13, blood urea nitrogen was 58, creatinine was 1.3, and blood glucose was 403, anion gap was 25. pt was 13.3, ptt was 23, inr was 1.2. alt was 13, ast was 24, alkaline phosphatase was 54, total bilirubin was 0.4. creatine kinase was 132. ck/mb was 10. ck/mb index was 7.6. acetone was negative. troponin was 7.6. urinalysis showed a glucose of greater than 1000, was clear. arterial blood gas done on 91% saturation on room air revealed ph was 7.43, pco2 was 31, po2 was 95. radiology/imaging: electrocardiogram showed a normal sinus rhythm with heart rate of 98, normal axis, 2-mm st depressions in leads i, avl, v4, v5, and v6. a chest x-ray showed bibasilar patchy opacities that may be consistent with some pulmonary edema. hospital course: 1. gastrointestinal: the patient was anemic secondary to a peptic ulcer bleed or nonsteroidal antiinflammatory drug induced gastritis. he was given 4 units of packed red blood cells, and his hematocrit appropriately went from 18.9 to 28.3. he was given protonix 40 mg p.o. q.d. for prophylaxis. his aspirin was withheld due to the bleed. the patient was scoped on . 2. cardiovascular: the patient had a demand ischemia and lateral infarct, according to cardiac enzymes changes and electrocardiogram changes. his infarct was located laterally; according to the st depressions that were found in leads i, avl, and v4 through v6. these electrocardiogram changes remained stable and unchanged throughout the hospital course. over a 24-hour period, his creatine kinase did rise from 132, peaking at 696, and then declining down to 419. his ck/mb was 10 on admission, peaking at 71, and trending down to 27. his creatine kinase index was 7.6 on admission, peaking at 12.1, and trending down to a normal value of 6.4. his cardiologist, dr. , did see him in house and recommended that a beta blocker be added to his medication regimen. metoprolol 25 mg p.o. b.i.d. was added. with regard to coronary artery disease, the patient's aspirin was held in light of his gastrointestinal bleed. with regard to the hypertension, the patient's blood pressure remained within the normal systolic range of 90 to 135 over the hospital course. as for his congestive heart failure, the patient remained clinically asymptomatic and was saturating above 90% during the hospital stay. 3. respiratory: the patient did have a bilateral basilar opacity on the chest x-ray. however, he did not have any respiratory problems clinically. after his transfusion of 4 units of packed red blood cells, the patient was not given any additional intravenous fluids that would exacerbate his congestive heart failure. it was recommended that he follow up with a chest x-ray within one week. 4. hematology: the patient's anemia resolved with a transfusion of 4 units of packed red blood cells. his hematocrit appropriately bumped from 18.9 to 28.3. 5. endocrine: since the patient was started on a clear liquid diet, per gastroenterology recommendations, he was restarted on his metformin 850 mg p.o. b.i.d. his medication adequately controlled his fingerstick blood sugar levels of below 100s. 6. renal: the patient did have a anion gap metabolic acidosis with a transfusion and hydration, the patient's acidosis did resolve. also, the hydration also helped resolve his prerenal azotemia because his creatinine went from 1.7 back to a baseline of 1.3. condition at discharge: condition on discharge was stable. discharge status: discharge status was to home. medications on discharge: 1. protonix 40 mg p.o. q.d. 2. metformin 850 mg p.o. b.i.d. 3. lipitor 10 mg p.o. q.d. 4. lopressor 50 mg p.o. q.d. discharge diagnoses: 1. anemia secondary to upper gastrointestinal bleed. 2. lateral myocardial infarction due to demand ischemia. 3. coronary artery disease. 4. hypertension. 5. congestive heart failure. 6. diabetes mellitus. 7. prerenal azotemia. discharge followup: the patient was to follow up with his primary care provider (dr. ) within one week after discharge. recommendation of a follow-up chest x-ray in one week and consideration of possibly restarting aspirin at some time in the future. , m.d. dictated by: medquist36 d: 15:14 t: 08:51 job#: procedure: other endoscopy of small intestine diagnoses: acidosis pure hypercholesterolemia mitral valve disorders congestive heart failure, unspecified unspecified essential hypertension acute posthemorrhagic anemia aortocoronary bypass status chronic or unspecified gastric ulcer with hemorrhage, without mention of obstruction acute myocardial infarction of other lateral wall, initial episode of care 

Answer: The patient is high likely exposed to
