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 is an 84-year-old gentleman who presented to admit emergency room on , after being found on the ground at home by the visiting nurse. he was found to have a tender right fourth toe ulcer with mild erythema. he was afebrile. he was evaluated by his podiatrist who did a right fourth toe amputation. he was transferred here for further vascular evaluation and treatment. past medical history: peripheral vascular disease, history of alcohol abuse, history of type 2 diabetes noninsulin- dependent, history of colonic polyps, history of hypertension, history of bph status post turp, history of gastroesophageal reflux disease, history of coronary artery disease, status post cardiac catheterization, history of gi bleeds, history of hemorrhoids. allergies: iv contrast, reaction unknown. medications: glipizide 10 mg daily, lisinopril 20 mg daily, lopressor 50 mg daily, neurontin 300 mg 3 times daily, metformin 500 mg twice a day, lynina 50 mg 3 times daily. physical examination: vital signs are stable. the patient is afebrile and is in no acute distress. lungs were clear to auscultation. heart was regular rate and rhythm without murmur, gallop or rub. abdomen was soft, obese, nontender, nondistended with normal bowel sounds. extremity exam shows right fourth toe amputation site closed and clean with dopplerable pedal pulses on the right and palpable pedal pulses on the left with palpable femoral and popliteal pulses bilaterally. hospital course: the patient was transferred from admit to the in-house service of dr. . he was continued on his transfer medications. antibiotics of vancomycin, cipro and flagyl were instituted. arterial studies were canceled. the patient underwent a diagnostic arteriogram on . angiographic findings showed infrarenal abdominal aorta patent with bilateral single renal arteries. the infrarenal abdominal aorta is severely diseased and calcified and aneurysmal. the common iliac, external iliac arteries were patent. there is severely calcified disease throughout. there is moderate stenosis across the left iliac system with a pressure gradient of 10 mm. the right lower extremity runoff revealed a patent common with moderate posterior common femoral plaque. there is common profunda and superficial femoral artery. the sfa is patent but severely diseased with multiple areas of high grade stenosis and focal occlusions. there is reconstitution of a diseased popliteal artery with a 2 vessel runoff via the peroneal. the anterior occludes proximally and then reconstitutes at the ankle and to a widely patent distal anterior tibial and dorsalis pedis. at the foot, we see reconstitution of the distal segment of the posterior tibialis but this is small and stenotic. it continues into a patent plantar bifurcation. the patient underwent a right femoral endarterectomy with a dacron patch angioplasty and a right fem to dp bypass with in-situ saphenous vein. the patient tolerated the procedure well and was transferred to the pacu in stable condition. the patient remained hemodynamically stable and was transferred to the vicu for continued postoperative care. the right foot was warm with a palpable dp pulse. postoperative day 1, the patient had some episodes of sino bradycardia without hemodynamic compromise. his diet was advanced as tolerated. his postoperative hematocrit was 25.8, down from 30.4. he was transfused 2 units of packed cells. his preoperative medications were reinstituted. his iv fluids were placed at maintenance infusion rate. he remained on bedrest and in the vicu. postoperative day 2, the patient continued to do well. he was delined and transferred to the regular nursing floor. ambulation to a chair was begun. physical therapy was requested to evaluate the patient for discharge planning. case management was consulted to plan for discharge planning. the patient will be discharged when medically stable and evaluated by physical therapy. discharge medications: 1. metoprolol xl 50 mg daily. 2. metformin 500 mg daily. 3. glyburide 10 mg daily. 4. senna tabs 1 twice a day p.r.n. 5. colace 100 mg twice a day. 6. oxycodone acetaminophen 1-2 tablets q.4-6 hours p.r.n. for pain. 7. protonix 40 mg daily. 8. gabapentin 300 mg 3 times daily. 9. zoloft 50 mg daily. 10. ferrous sulfate 325 mg twice a day. 11. lisinopril 20 mg daily. discharge instructions: the patient may ambulate essential distances, full weightbearing, to wear a healing sandal and should wear ace wrap from foot to knee on the operative side. he should keep the right leg elevated when sitting in a chair. he may shower but no tub baths. he should continue all medications as directed. he should follow up with dr. in 2 weeks time. he should call for an appointment at . he should also call the office if he develops a fever greater than 101.5 or the leg wounds become red or drain or the groin wounds become swollen. discharge diagnoses: 1. right foot ischemia, status post diagnostic arteriogram, status post right femoral endarterectomy with a femoral to dorsalis pedis bypass graft. 2. past medical history of alcohol abuse. 3. history of type 2 diabetes noninsulin-dependent. 4. history of colonic polyps. 5. history of hypertension. 6. history of benign prostatic hypertrophy, status post transurethral resection. 7. postoperative blood loss anemia, transfused. discharge medications: unchanged from preoperative medications. , procedure: arteriography of femoral and other lower extremity arteries other (peripheral) vascular shunt or bypass transfusion of packed cells endarterectomy, lower limb arteries procedure on single vessel diagnoses: coronary atherosclerosis of native coronary artery esophageal reflux mitral valve disorders unspecified essential hypertension acute posthemorrhagic anemia diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled hypertrophy (benign) of prostate without urinary obstruction and other lower urinary tract symptom (luts) percutaneous transluminal coronary angioplasty status ulcer of other part of foot atherosclerosis of native arteries of the extremities with ulceration
