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 85-year-old nondiabetic white male with coronary artery disease, status post myocardial infarction, status post icd, hypertension, peripheral vascular disease, who had undergone a right femoral to above the knee popliteal bypass graft with ptfe on by dr. for symptoms of right leg claudication. patient did well without symptoms of claudication or rest pain, but did note that his feet felt particularly cold in the past several months. on the morning of admission, the patient experienced right foot pain when he woke up and tried to get out of bed. his foot was cold, mottled and numb. son brought him to the emergency room at hospital in port. dr. was contact and patient was transferred to the emergency room at , and then was admitted for further evaluation and treatment. past medical history: 1. coronary artery disease, status post inferior myocardial infarction; ejection fraction 20%. 2. cardiac dysrhythmia: history of first degree av block, wenckebach; icd placed in . 3. hypertension. 4. peripheral vascular disease. past surgical history: 1. right femoral to above the knee popliteal bypass graft with ptfe on by dr. . 2. icd placed at outside hospital. 3. cataract extraction and intraocular lens o.u. allergies: no known drug allergies. admission medications: 1. plavix 75 mg po q.d. 2. aspirin 325 mg po q.d. 3. folic acid 1 mg po q.d. 4. toprol xl 12.5 mg po q.d. 5. lisinopril 5 mg po q.d. 6. diltiazem cd 90 mg po q.d. 7. lasix 20 mg po q.a.m. 8. protonix 40 mg po q.d. 9. aciphex 90 mg po q.d. 10. lipitor 10 mg po q.d. 11. nicotine patch 14 mcg q.d. family history: noncontributory. social history: patient does not drink alcohol. he is in the process of stopping to smoke cigarettes. physical examination: vital signs: temperature 98. pulse 71. respiratory rate 14. blood pressure 160/71. oxygen saturation equals 100% on room air. general: alert, cooperative white male in no acute distress. chest: lungs clear bilaterally. heart regular rate and rhythm. abdomen soft, nontender. extremities: left foot warm, right foot cold and mottled. a pulse exam; carotid pulses palpable bilaterally without bruits. right femoral and popliteal pulses nonpalpable. no doppler signals at the right pedal pulses. left femoral pulse is 1+. left popliteal, dorsalis pedis and posterior tibial pulses have doppler signals. the abdominal aorta is nonpalpable and without bruits. admission laboratories: white blood cell count 10.9, hemoglobin 13.1, hematocrit 40.0, platelet count 162,000, pt 12.3, ptt 23.7, inr 1.0, sodium 138, potassium 3.8, chloride 100, co2 27, bun 7, creatinine 1.1, glucose 92. electrocardiogram showed an arterial ventricular paced rhythm. ventricular bigeminy and trigeminy. chest x-ray showed no acute pulmonary disease. hospital course: the patient was admitted to the hospital on . an emergent arteriogram was done which showed that the ptfe graft was occluded with thrombus extending proximally to the right external iliac artery. there was a focal infrarenal abdominal aortic aneurysm and a high grade left renal artery stenosis. thrombolysis was started with tpa. patient developed a large left groin hematoma where the sheath was placed. the size of hematoma was approximately 20 x 10 cm. patient was monitored in intensive care unit setting. the follow-up arteriogram on the following day showed that the distal anastomosis of the bypass graft was occluded. patient's fibrinogen was abnormally low at 102. the tpa infusion was stopped. patient's hematocrit fell from 40 to 30 following development of the left groin hematoma. patient was transfused a unit of packed red blood cells. ultrasound on showed no pseudoaneurysm of the left groin. patient was taken to the operating room on and underwent an uneventful right femoral thrombectomy and right femoral to anterior tibial artery bypass graft with nonreversible saphenous vein. at the end of surgery, patient had a warm foot. his graft was palpable at the medial knee. his pedal pulses on the right had doppler signals. perioperatively, patient received kefzol. postoperatively, he received several more units of packed red blood cells. at the time of discharge, his hematocrit is 33. postoperatively, patient developed some abdominal distention. he was made npo and a nasogastric tube was placed overnight. the following morning nasogastric tube was removed and patient was given clear liquids and his diet was advanced without further abdominal problems. patient had some episodes of liquid stool. clostridium difficile cultures were negative. physical therapy worked with the patient and recommended rehabilitation stay because patient was below his baseline of physical ability. patient would also be home alone during the day since family members were at work. at the time of dictation, patient's right leg incision was clean, dry and intact. he had a palpable graft pulse and doppler signals of his pedal pulses. his left hip to groin area including his penis and scrotum were ecchymotic. his right forearm was also ecchymotic. these areas were nontender. patient will follow-up with dr. for staple removal in about two weeks at his satellite office. dr. office should be called for an appointment at . addendum: prior to surgery, patient had been evaluated by the cardiology service for preoperative clearance. several recommendations for postoperative management were made. otherwise, no further testing was recommended since patient had undergone a pharmacological stress test in , which was normal. discharge medications: 1. lopressor 50 mg po b.i.d., hold for systolic blood pressure less than 110, heart rate less than 55. 2. diltiazem 30 mg po t.i.d., hold for systolic blood pressure less than 100, heart rate less than 55. 3. folic acid 1 mg po q.d. 4. atorvastatin 10 mg po q.d. 5. aspirin 325 mg po q.d. 6. protonix 40 mg po q.d. 7. heparin 5000 units subcutaneously q. 12 hours. 8. percocet 1-2 tablets po q. 4-6 hours prn pain. 9. ambien 5 mg po q.h.s. prn. disposition: rehabilitation facility. condition at discharge: satisfactory. primary diagnoses: 1. acutely ischemic right leg secondary to right bypass graft occlusion. 2. unsuccessful thrombolysis of occluded bypass graft. 3. right femoral thrombectomy and redo right femoral anterior tibial artery bypass graft with nonreversible greater saphenous vein on . secondary diagnoses: 1. blood loss anemia. 2. left groin hematoma. 3. postoperative ileus. 4. ventricular ectopy. 5. hypertension. 6. coronary artery disease with history of myocardial infarction. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified other revision of vascular procedure injection or infusion of thrombolytic agent arteriography of femoral and other lower extremity arteries other (peripheral) vascular shunt or bypass transfusion of packed cells diagnoses: coronary atherosclerosis

Answer: The patient is high likely exposed to
