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 48 year-old male well known to our service with a history of hypertension, gastroesophageal reflux disease, severe peripheral vascular foot pain times duration of four days. the patient reportedly noticed this a.m. his pain has gotten much worse then previously and his left leg and foot has gotten cold. he also noted that he had no longer can feel his left femoral pulse, which is a change. the patient was originally scheduled for surgery electively next tuesday with dr. , but now is admitted urgently for ischemic room. he was begun on intravenous heparin. past medical history: hypertension, gastroesophageal reflux disease, peripheral vascular disease. past surgical history: aortobifemoral in , left femoral ak in , left fem ak with dacron in , right femoral popliteal with ptfe and a right femoral popliteal with arm vein in . revision of the aortobifemoral and left femoral ak . in of this year left common femoral artery to profunda with dacron bypass in . allergies: no known drug allergies. medications on admission: lopresor 12.5 mg b.i.d., prilosec 20 mg b.i.d., procardia xl 30 mg q.d., zestril 10 mg q.d., coumadin 7.5 mg q.d., amitriptyline 25 mg at h.s. social history: the patient has a fifty pack year history of smoking. he was previously a three pack per day and he has now decreased his smoking to one pack per day. physical examination: vital signs 99.4. pulse 114. blood pressure 145/67. respiratory rate 18. o2 sat 96% on room air. general appearance, the patient is in mild distress secondary to pain. heent examination is unremarkable except for bilateral carotid bruits. chest is clear to auscultation bilaterally. heart is a regular rate and rhythm without murmurs, rubs or gallops. abdominal examination is unremarkable. there is no problems with the abdominal aorta. extremity examination left foot is modeled, cold with delayed capillary refill. he has absent femoral, popliteal, dorsalis pedis pulse and posterior tibial pulses on the left. on the right he has a palpable femoral popliteal triphasic dorsalis pedis and posterior tibial signal on the right. laboratory: laboratories included a cbc with a white blood cell count of 12.7, hematocrit 32.9, platelets 302k, bun 6, creatinine .8, k 4.5. pt, inr, ptt were normal. vascular surgery was consulted. hospital course: the patient was taken to angiography. angiography noted prior aortobifemoral bypass with occluded left limb of the aortobifemoral. an attempt was to cross lesion from the right groin, successful with wire, unsuccessful with a gldewire and catheter as well as a 6 french sheath. the left groin was entered in a retrograde fashion. the left femoral was accessed. the infusion catheter was placed at the limb of the abf graft. tissue plasminogen activator was begun at 1 mg per hour. the following day repeat arteriogram was done. the patient's left limb of the aortobifemoral was patent. the left common femoral to profunda graft was occluded. the left femoral to ak bypass with dacron was patent with distal stenosis and no run off. the patient was taken to surgery and underwent at that time a left femoral popliteal revision with a femoral popliteal to bypass jump graft to bk of ptfe and left leg 4 compartment fasciotomies. intravenous heparinization was begun. the patient was transferred to the cicu for continued monitoring and care. postoperative day one the patient's foot remained good. he had a palpable graft pulse. he required intravenous nitroglycerin for his hypertension. morphine pca was converted to oral analgesic agents and his diet was advanced as tolerated. on postop day number two the patient was transferred to the vicu for continued monitoring and care. postop day number three the patient had a t max of 101.5. vancomycin was begun empirically. heparin was continued and coumadization was begun. cultures were sent. blood cultures were obtained, which finalized as no growth. chest x-ray was also obtained at that time, which demonstrated a mild congestive heart failure with volume overload. there was a more focal opacity within the right middle lobe for which focal pneumonia could not be excluded. venous duplex were done, which were negative for deep venous thrombosis. ambulation was begun and on he underwent closure of his fasciotomy sites without complications. duplex of the graft was done, which showed a patent graft without stenosis. duplex of the veins were negative for deep venous thrombosis, but did show a left calf hematoma. his hematocrit dropped and he required transfusions for a hematocrit of 26. he was continued on heparin and coumadin anticoagulation and on he underwent an incision and drainage of the left graft hematoma without problems. required two packed red blood cells for a hematocrit of 28.2. the patient was followed by physical therapy and they felt he would be safe to be discharged to home. the patient would be discharged to home in stable condition once inr remained at a steady therapeutic state of 1.9 or greater. heparin would be discontinued at that time. wounds at the time of discharge were clean, dry and intact. he had a palpable graft pulse. at the time of discharge the patient's hematocrit was 30.8 with a white count of 10.3. his inr on was 1.7 with a ptt of 60.6. discharge medications: coumadin 10 to 15 mg q.d. maintain an inr between 2.0 and 3.0. gabapentin 400 mg t.i.d., pantoprazole 40 mg b.i.d., amitriptyline 25 mg at h.s., ambien 5 mg at h.s. prn, nifedipine cr 30 mg q.d., lisinopril 10 mg q.d., percocet tablets one to two q 4 to 6 hours prn for pain, colace 100 mg b.i.d., nicotine patch 21 mg q.d. this should be for a total of twenty one days and this should be reassessed to determine whether he can go to a lower dosing. bupropion sr 150 mg b.i.d., metoprolol 100 mg b.i.d. care to left calf dry sterile dressing q.d. the patient should follow up with dr. in two to three weeks. discharge diagnosis: 1. ischemic left leg status post arteriogram and tissue plasminogen activator. 2. status post revision of femoral popliteal with a jump graft from femoral popliteal graft to bk popliteal with ptfe. 3. left leg fasciotomies. fasciotomy sites closed . 4. blood loss anemia corrected. 5. left calf hematoma status post incision and drainage. , m.d. dictated by: medquist36
