well healed left leg bypass scar. pulses 2+ radial bilaterally, 2+ dorsalis pedis and 1+ posterior tibial bilaterally. laboratory data: white count 5.8, hematocrit 28.2, platelets 118, pt 13.6, ptt 58.4, inr 1.2, sodium 132, potassium 3.9, chloride 99, co2 22, bun 32, creatinine 0.9, glucose 182, alt 18, ast 16, alk phos 57, amylase 36, total bili 0.6. ua is negative. carotid ultrasound with less than 40 percent stenosis bilaterally. lower extremity vein mapping: patent right greater saphenous vein from the ankle to the upper thigh. following cardiac catheterization, ct surgery service was consulted. the patient was seen and accepted for coronary artery bypass grafting and on , the patient was brought to the operating room where he underwent cabbage x4. please see the or report for full details. in summary, the patient had a coronary artery bypass graft times four with lima to the left anterior descending; saphenous vein graft to the posterior descending artery, saphenous vein graft to the ramus with a jump to the obtuse marginal. his bypass time was 85 minutes with a cross clamp time of 55 minutes. he tolerated the operation and was transferred from the operating room to the cardiothoracic intensive care unit. at the time of transfer, the patient was a paced at 88 beats per minute with a mean arterial pressure of 85 and a pad of 12. he had milrinone at 0.5 mcg kilogram per minute, nitroglycerin at 1 mcg/kg minute; insulin drip, titrated to blood glucose and propofol at 28 mcg/kilogram per minute. the patient did well in the immediate postoperative period. his anesthesia was reversed. he was weaned from his ventilator and successfully extubated. he remained hemodynamically stable throughout the operative day. on postoperative day one, the patient continued to be hemodynamically stable. he was weaned from his milrinone and nitroglycerin infusions. his chest tubes were removed. he remained in the cardiothoracic icu because of his cardioactive intravenous medications. on postoperative day two, the patient was started on beta blockade. he was also begun on diuretics. an ace inhibitor was begun and he remained in the icu because it was noted overnight that he had short episodes of two to one heart block, during which he remained hemodynamically stable. on postoperative day 3, the patient remained hemodynamically stable. his central lines were discontinued. during this time, he was noted to have periods of increasing confusion and agitation, from which he was easily reoriented. an a wire trace done on postoperative day 3, showed that the patient did not have two to one heart block but was indeed in sinus rhythm with appropriate ventricular response. on postoperative day 4, the patient's temporary pacing wires were removed and he was transferred to the floor for continuing postoperative care and cardiac rehabilitation. throughout the next several days, the patient had an uneventful postoperative course. his activity level was increased with the assistance of the nursing staff and physical therapy. on postoperative day 7, he had a duplex of his femoral graft to assess patency. it was found to be patent and at that time, it was decided that the patient was stable and ready to be discharged to home on the following day. physical examination: at the time of this dictation, the patient's physical exam is as follows. vital signs temperature 98.4, heart rate 73. blood pressure 138/60; respiratory rate of 18. o2 sat 95 percent on room air. laboratory data: sodium 138, potassium 4.4, chloride 99, co2 31, bun 23, creatinine 1.0, glucose 138, white count 7.2; hematocrit of 34.6. platelets 355. physical examination: neurologic: alert and oriented times three. moves all extremities. follows commands. respiratory clear to auscultation bilaterally. cardiovascular regular rate and rhythm, s1-s2. sternum is stable. incision with steri-strips, open to air, clean and dry. abdomen is soft, nontender, nondistended with positive bowel sounds. extremities: cool with no edema. positive pulses bilaterally. right saphenous vein graft harvest site with steri-strips open to air, clean and dry. disposition: patient is to be discharged to home with visiting nurses. his condition at the time of discharge is good. discharge diagnoses: cad status post coronary artery bypass grafting times four with lima to the lad, saphenous vein graft to the pda, saphenous vein graft to the ramus with a jump to the om peripheral vascular disease. status post appendectomy. status post sfa bypass. diabetes mellitus. . discharge medications: 1. zantac 150 b.i.d. 2. aspirin 325 every day. 3. percocet 5/325 1-2 tablets every four to six hours p.r.n. 4. plavix 75 mg every day. 5. metformin 500 mg b.i.d. 6. atorvastatin 10 mg every day. 7. lopressor 25 mg b.i.d. 8. lisinopril 10 mg every day. 9. glyburide 5 mg every day. 10. lasix 20 mg every day times 7 days. 11. potassium chloride 20 meq. every day times 7 days. follow up: the patient is to have follow-up with dr. in two to three weeks. follow-up with dr. in weeks. follow-up with dr. in 3 months. follow-up with dr. in six weeks. , procedure: (aorto)coronary bypass of three coronary arteries single internal mammary-coronary artery bypass extracorporeal circulation auxiliary to open heart surgery combined right and left heart cardiac catheterization coronary arteriography using two catheters angiocardiography of left heart structures transfusion of packed cells diagnoses: subendocardial infarction, initial episode of care anemia, unspecified coronary atherosclerosis of native coronary artery mitral valve disorders congestive heart failure, unspecified unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled percutaneous transluminal coronary angioplasty status other complications due to other cardiac device, implant, and graft 

Answer: The patient is high likely exposed to
