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 a 75-year-old gentleman with a significant past medical history with coronary artery disease status post stenting, chronic obstructive pulmonary disease, syndrome of inappropriate antidiuretic hormone and peripheral vascular disease. he presented to caritas two to three weeks prior to transfer here for right foot pain. the patient states that his pain became progressively progressed to the point he was unable to walk. this was associated with swelling. therefore, he was evaluated on , at caritas. he was found to have a normal white count of 9.4 and was afebrile. he was also found to have urinary retention. he was started on vancomycin and zosyn and was transferred to our institution for further workup and possible vascular intervention. the patient was known peripheral vascular disease. he was to have an elective leg re-vascularization by dr. and this was cancelled due to the patient's significant history of chronic obstructive pulmonary disease. the patient denies any constitutional symptoms, shortness of breath, chest pain, nausea, vomiting or bowel habit changes. he was treated at caritas for right lower lobe pneumonia as well as chronic obstructive pulmonary disease exacerbation. past medical history: illnesses: chronic obstructive pulmonary disease, coronary artery disease, paroxysmal atrial fibrillation anticoagulated, peripheral vascular disease, history of alcohol abuse, history of siadh. past surgical history: coronary artery stenting, vessels unknown. medications: medications at home include nitroglycerin sublingual, atrovent, procardia 240 mg er, ecotrin 81 mg daily, lasix 40 mg twice a day, pravastatin 40 mg twice a day, pulmicort, spiriva, vitamin b12, xopenex 0.4 mg four times a day p.r.n. transfer medications were vancomycin 1 gram every 12 hours, zosyn 3.375 grams every 8 hours, omeprazole, acetaminophen, morphine, lovenox 30 mg, diltiazem 240 mg, ecotrin 81 mg, simvastatin 20 mg, vitamin b12 500 mg and spiriva. social history: the patient can ambulate and take care of himself before it became too painful to walk. he has a heavy smoking history of one to two packs per day for approximately 60 years. he quit three months ago. he does have a history of alcohol excess and admits to drinking one 12-ounce beer per night. physical examination: vital signs: 98.4, 86, 18, o2 saturation 955 on 2 liters, blood pressure 133/67. general appearance: alert and oriented x3, appears somewhat uncomfortable with movement of the foot. heent examination is unremarkable. neck is supple. carotid pulses are symmetrical. there are no carotid bruits. heart is a regular rate and rhythm with a 2/6 systolic ejection murmur. lungs increased ap diameter and sounds are distant globally. abdominal examination is unremarkable. there are no intra- abdominal bruits. a foley is in place. extremity examination shows 3+ edema right greater than left. the right foot is with blanching erythema extending to just proximal to the ankle and diffuse erythema of the leg to the hip. it is more pronounced on the dorsal leg. there are multiple scars and superficial erosions on the anterior tibia. toes two, three and four with violaceous ischemic appearance. capillary refill is greater than 3 seconds. there are small ulcers in the web spaces in the interdiginous areas between the toes with fibrinous purulent exudate. the fourth toenail is separating. overall, foot is somewhat cool to touch with toes being most pronounced compared to the contralateral side. overall, poor foot hygiene. left foot is warm with adequate perfusion. pulse examinations: carotids 2+, radials 2+, femoral faintly palpable on the left and 1+ on the right. on the left, the popliteal is palpable. the dorsalis pedis and posterior tibial are monophasic signals. on the right, the popliteal, dorsalis pedis are absent. the posterior tibial is a monophasic signal. hospital course: the patient was admitted to the vascular service. he was continued on his antibiotics. podiatry was consulted. they felt at this time there was no surgical indication to treat the foot or leg lesions. they recommended to continue antibiotics, daily wound care with betadine to the lesions and the patient could ambulate full weightbear with a healing sandal. outside, a ct of the abdomen and aorta with runoffs falling. there is complete occlusion of the left external iliac artery, occlusion of the proximal superficial femoral artery with reconstitution of the distal superficial femoral artery with large deep femoral artery with three-vessel runoff. on the right side, there was stenosis in the proximal common iliac and external iliac arteries with a high-grade stenosis of the deep femoral artery, poor collateral flow distally, some reconstitution of the right popliteal artery and two-vessel runoff on the right ankle with dominant vessel being posterior tibial. there was severe atherosclerotic and mesenteric and renal artery changes. the patient underwent arteriogram on , without complication. he was recommended that he could be revascularized. outside cultures grew methicillin-sensitive staphylococcus aureus, methicillin-resistant staphylococcus aureus. the patient was continued on vancomycin, cipro and flagyl. the patient underwent on , a right femoral endarterectomy with a right superficial femoral artery posterior tibial bypass with non-reverse saphenous vein graft, angioscopy and valve lysis. the patient required 2 units of packed red blood cells intraoperatively. the patient tolerated the procedure well and was transferred to the postanesthesia care unit in stable condition. postoperatively, he remained hemodynamically stable. he was transfused 2 units of packed red blood cells. he continued to do well and was transferred to the vicu for continued monitoring and care. on postoperative day one, there were no overnight events. t-max was 100.4 to 99. his blood gases were 7.34, 43, 76, 24, -2. hematocrit was 31.3. bun 5, creatinine of 0.6. pulse examination on the right side showed a pt signal. foot was warm. the patient remained in the vicu. intravenous fluids were hep-lock'd. diet was advanced. postoperative day two, the patient continued to do well. the right second toe remained ischemic in appearance. the swan was discontinued. he required diuresis. he was allowed to ambulate to a chair. his t-max was 100.2 to 99.6. he remained in the vicu. most of the time he was noted to be hyponatremic with a sodium of 122. fluid restriction of 1000 cubic centimeters per 24 hours was instituted along with salt tablets 1 gram twice a day. hematocrit remained stable at 29.5. antibiotics were continued. diuresis continued and the patient remained on a ciwa scale for his history of alcohol use. the patient did demonstrate some mild confusion which we felt was secondary to his hyponatremia. postoperative day three, there were no overnight events. he was continued in the vicu. he was de-lined. chair ambulation was continued. physical therapy was prescribed to see the patient and he was transferred to the regular nursing floor for continued care. the patient underwent a right second toe amputation on . he tolerated the procedure well. he was reevaluated by physical therapy who felt he would require rehabilitation prior to being discharged to home. postoperative day five and one, the patient continued to do well. intravenous antibiotics were discontinued. bactrim was instituted. coumadinization was reinstituted for his history of fibrillation. he was given 5 mg. sodium was continued to be monitored. sodium continued to show improvement. he continued with the fluid restriction and salt tablets. on postoperative day number six, the patient continued to do well. sodium was 128. he was afebrile. his amputation site wound looked clean, dry and intact. ambulation essential distances full weightbearing with healing sandal was instituted. he was screened by physical therapy and rehab. he will be transferred to rehab for continued postoperative care in stable condition. discharge instructions: the patient may shower but no tub baths. he may ambulate essential distances with healing sandal. if he develops any fevers, wound changes consisting of redness, drainage or groin swelling or drainage, please notify dr. office. his antibiotics should be continued until seen in follow up. his inr should be monitored on a daily basis for goal inr of 2.0 to 3.0. coumadin should be adjusted as needed. the patient is on bactrim which interacts with coumadin and may elevated the inr. the sodium should also be monitored. his current sodium is 128 on a fluid-restriction of 1200 cubic centimeters per 24 hours and 2 grams of sodium tablets twice a day. the patient should follow up with dr. in two to three weeks. discharge diagnosis: arterial insufficiency with ischemic right
