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: the patient is a 56 year-old male with positive ett and hypertension, hypercholesterolemia admitted with elective catheterization, which showed a left main coronary artery disease of 60 to 70% occlusion, left anterior descending coronary artery moderate calcification, left circumflex normal, right coronary artery and distal chronic aortic dissection. ejection fraction at the time was estimated to be 60%. past medical history: significant for hypertension, hypercholesterolemia and alcohol abuse. medications at home: lopressor, nitroglycerin and lipitor. hospital course: the patient underwent coronary artery bypass graft times three on by dr. . there was a left internal mammary coronary artery to left anterior descending coronary artery, saphenous vein graft to obtuse marginal one, and saphenous vein graft to right posterior descending coronary artery. postoperatively, the patient was extubated and weaned off drips in the intensive care unit. however, the patient developed delirium tremor postoperatively and was placed on ativan protocol. psychiatry was consulted. the patient was placed on the ativan protocol and was weaned off and the patient was stabilized and was doing well and transferred to the floor on postoperative day five. once transferred to the floor the patient was found to have a cold left lower extremity. it became acutely ischemic and arteriogram at that time showed no satisfactory vascular arteriole target that was able to be bypassed. vascular surgery was consulted and recommended below the knee amputation of left lower extremity. the patient underwent below the knee amputation of left lower extremity on the . following that the patient did well and was subsequently extubated and weaned off drips and transferred to the floor without incidence. also, the sputum culture on was positive for pseudomonas and hemophilias and ________ growth. the patient was placed on a ten day course of cipro and ceptaz. upon discharge the patient finished a ten course of cipro and ceptaz and subsequent culture was negative. the patient was afebrile and was stable. upon transfer to the floor the patient was able to work with physical therapy. foley was discontinued without incidence. however, immediately postop the patient did require a standing dose of haldol due to confusion and agitation. prior to discharge the sitters have been discharged and the patient has not required haldol prior to discharge and the patient is alert and oriented times three and the patient was cooperative and working with physical therapy in ambulation. discharge medications: lopressor 75 mg po t.i.d., captopril 12.5 mg po t.i.d., thiamine 100 mg po q.d., heparin subq 5000 units b.i.d., neurontin 300 mg po q.d., motrin 800 mg po t.i.d., aspirin 81 mg po q.d., folate 1 mg po q.d., zantac 150 mg po b.i.d, percocet one to two tabs po q 4 to 6 h prn, colace 100 mg po b.i.d. and lipitor 10 mg po q.d. discharge condition: the patient was stable and afebrile. vital signs were stable. chest was clear to auscultation. heart rate was regular rate and rhythm, normal sinus. sternum was stable. left stump clean, dry and intact. it had some minimal serosanguinous drainage. vascular was consulted and it was recommended just wrapping the stump with kerlix bandage. the stump looks clean. no erythema. no inflammation. no pus drainage. the patient was alert and oriented times three. the patient will be discharged to a rehab facility and was told to follow up with dr. in three to four weeks. also is to follow up with the vascular service in two to three weeks. , m.d. dictated by: medquist36 procedure: 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 (aorto)coronary bypass of two coronary arteries angiocardiography of left heart structures angioplasty of other non-coronary vessel(s) arteriography of femoral and other lower extremity arteries other amputation below knee diagnoses: coronary atherosclerosis of native coronary artery intermediate coronary syndrome tobacco use disorder diarrhea other and unspecified alcohol dependence, unspecified arterial embolism and thrombosis of lower extremity pneumonia due to hemophilus influenzae [h. influenzae] embolism and thrombosis of iliac artery alcohol withdrawal delirium 

Answer: The patient is high likely exposed to
