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: this 57-year-old white male has a history of diabetes, hypertension, and peripheral vascular disease. he presented to hospital after episodes of chest pain and shortness of breath. an electrocardiogram revealed anterior ischemia with st elevations in v2-v3, along with anterior qs. he also had positive enzymes and was placed on a heparin drip, integrilin, plavix, and nitropaste. he was transferred to and was admitted. he recently had a right popliteal to right plantar bypass in at . past medical history: insulin-dependent diabetes for 17 years. peripheral vascular disease status post right popliteal to right plantar bypass in . history of hypertension. history of retinopathy. history of peripheral neuropathy. medications on admission: lopressor 25 mg p.o. b.i.d., zantac 150 mg p.o. b.i.d., nph insulin 54 u q.a.m., 59 u q.p.m., percocet p.r.n. allergies: no known drug allergies. social history: he lives alone. he does not smoke cigarettes. he has a 10 pack-year history, but quit 35 years ago. he does not drink alcohol. family history: unremarkable. review of systems: as above. physical examination: general: he was a well-developed, well-nourished white male in no apparent distress. vital signs: stable and afebrile. heent: normocephalic, atraumatic. extraocular movements intact. oropharynx benign. neck: supple. full range of motion. no lymphadenopathy or thyromegaly. carotids 2+ and equal bilaterally without bruits. lungs: clear to auscultation and percussion. cardiovascular: regular, rate and rhythm. normal s1 and s2. no murmurs, rubs, or gallops. abdomen: soft and nontender. positive bowel sounds. no masses or hepatosplenomegaly. extremities: without clubbing, cyanosis, or edema. he had a right lower extremity scar which was clean, dry, and intact. he had an ulcer on his right medial malleolus and the bottom of his foot. pulses: exam showed 2+ and equal on carotids, brachial, and femorals. neurological: he had decreased sensation on the bilateral feet. he was admitted to cardiology and was kept on his heparin drip, nitroglycerin drip, and aggrastat. he was also seen by vascular, and they stated that his right surgery failed, and he had a thrombectomy. he also had a right foot debridement on . his wounds were healing well. he remained stable and underwent cardiac catheterization on , which revealed that the left main had no significant obstructive disease, the left anterior descending had an ostial 70% and a distal 80% lesion, the left circumflex had no disease, the ramus 1 had a 50% midlesion, ramus 2 had a 90% ostial lesion, right coronary artery had a 70% posterior descending artery lesion at the ostium and an 80% mid posterior descending artery lesion. dr. was consulted, and on , the patient underwent coronary artery bypass grafting times four with lima to the left anterior descending, reversed saphenous vein graft to posterior descending artery, obtuse marginal and diagonal. cross-clamp time was 55 min. total bypass time was 65 min. he was transferred to the csru on dobutamine, lasix, neo-synephrine, and propofol. he had a stable postoperative night. his dobutamine was discontinued, and he was extubated. on postoperative day #1, he was transferred to the floor. he had 1 u of blood on postoperative day #2 for a hematocrit of 23. he continued to slowly progress. he was followed by vascular surgery who felt he should be seen a week after discharge by dr. and agreed with continuing b.i.d. dressing changes. he had his chest tubes discontinued on postoperative day #2. his pacing wires were discontinued on postoperative day #3. he had a slight bit of lower sternal drainage. this resolved, and the sternum was stable. he was also seen by , as he would like to change his insulin to lantus and humalog sliding scale. he also was seen by ophthalmology and has proliferative diabetic retinopathy in both eyes, and vitreous subhyaloid hemorrhage of the left eye, and he requires follow-up for this. he continued to progress slowly with physical therapy, and on postoperative day #8, he was discharged to rehabilitation in stable condition. discharge laboratory data: hematocrit 25.2, white count 10,100, platelet count 440,000; sodium 141, potassium 4.7, chloride 103, co2 29, bun 19, creatinine 0.9, blood sugar 97. discharge medications: colace 100 mg p.o. b.i.d., zantac 150 mg p.o. b.i.d., percocet p.o. q.4-6 hours p.r.n. pain, lopressor 50 mg p.o. b.i.d., lasix 40 mg p.o. b.i.d. x 1 week, captopril 6.25 mg p.o. t.i.d., glargine 45 u subcue q.h.s., humalog sliding scale. follow-up: he will be followed by dr. in weeks, dr. in four weeks, dr. in one week, dr. ................ within a month, and the clinic on . discharge diagnosis: 1. coronary artery disease. 2. myocardial infarction. 3. coronary artery bypass grafting. 4. insulin-dependent diabetes. , m.d. dictated by: medquist36 procedure: (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery angiocardiography of left heart structures left heart cardiac catheterization coronary arteriography using a single catheter transfusion of packed cells diagnoses: coronary atherosclerosis of native coronary artery unspecified essential hypertension acute myocardial infarction of other anterior wall, initial episode of care diabetes with neurological manifestations, type ii or unspecified type, not stated as uncontrolled polyneuropathy in diabetes peripheral vascular disease, unspecified diabetes with ophthalmic manifestations, type ii or unspecified type, not stated as uncontrolled ulcer of heel and midfoot ulcer of ankle
