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 77 year old gentleman with peripheral vascular disease who underwent a right below knee amputation on . the patient's postoperative course was significant for multiple infections of the stump and he returned to the clinic on multiple occasionswith swelling and erythema of this site with several large gangrenous ulcers of the stump and at the knee despite multiple courses of iv antibiotics. he had developed infection with resistent organisms due to prolonged iv antibiotic therapy. the decision was made given his long course of infections to proceed with a right above knee amputation. of note, the patient had been admitted about a month prior and has had an increase in the drainage from the stump site since then, with exposed bone. he had refused aka previously but accepted due to steadily advancing erythema and the risk of involvement of the ak amputation site and eventual systemic sepsis and death without amputation. he also refused any intervention for his cardiac disease. past medical history: diabetes mellitus, end stage renal disease on hemodialysis, gastroesophageal reflux disease, peripheral vascular disease, atrial fibrillation, congestive heart failure with an ejection fraction of 40 percent, severe mitral regurgitation with 3 plus mitral regurgitation on recent echocardiogram, aortic stenosis with a valve area of .7 to .8, depression, hypothyroidism and history of asbestos exposure. allergies: patient has no known drug allergies. medications on admission: calcium, sevelamer 800 mg by mouth 3 times daily, amiodarone 400 mg once daily, aspirin 81 mg by mouth daily, pyridoxine 150 mg by mouth daily, zoloft 75 mg by mouth daily, levoxyl 150 mcg by mouth daily, ritodrine 2.5 mg by mouth at dialysis, prilosec 20 mg by mouth daily, nph 12 units subcutaneously in the morning, 6 units subcutaneously in the evening, nephrocaps and epogen at dialysis. initial physical examination: he was afebrile with normal vital signs and in no acute distress. his heart was irregularly irregular. his chest was coarse with crackles. abdomen was soft, nontender, nondistended with normoactive bowel sounds. his right stump had multiple areas of necrotic tissue with exposed bone. there was erythema extending to the level of the mid knee. the left stump had a well healed wound. he had palpable femoral pulses bilaterally. initial laboratory data: white blood cell count 11.3, hematocrit 35.6, platelet count 283, pt 15.5, ptt 31.2, inr 1.5, potassium about 3.0. brief hospital course: mr. was admitted to the vascular service. the renal service was consulted given his hemodialysis needs and it was felt on hospital day number two that he would require additional dialysis preoperatively. the patient had received broad spectrum antibiotics. he was started on linezolid, meropenem and flagyl to cover previous vre and multiresistant acinetobacter which had grown from his wound. he was dialyzed preoperatively and was taken to the operating room on for conversion of a right below knee amputation to an above knee amputation. this was done under general endotracheal anesthesia. he received 400 cc of crystalloid in the procedure and tolerated it well. however, he was transferred to the recovery room requiring some neo-synephrine to maintain the systolic blood pressure in the 90s. he remained intubated immediately postoperatively and was extubated in the recovery room. however, within five minutes of extubation the patient failed to initiate respiratory effort and had additional drop in his blood pressure and oxygen saturation. he was emergently reintubated and was at one point weaned off his neo- synephrine. his ck, mb and troponins were checked and of note his cks were in the 20 to 30 range with a troponin of .3 going up to .5 cardiology was consulted and recommended consideration of a swan-ganz catheter to further guide his volume status. he dialyzed that afternoon and over the course of the night because more hypotensive with drop in his blood pressure to the 70s. he also did spike a temperature up to 39.3 degrees celsius. he was having swan-ganz catheter placed during the night which revealed high filling pressures and a wedge of 33. however, he did have a low cardiac index of 1.3 with an svr of 1800. he remained on antibiotics and on ventilator support. he was initially started on dobutamine with attempts to optimize his cardiac index. however, he did not tolerate this well, became tachycardic with low blood pressure and vasopressin was added to the regimen. however, after reconsultation with cardiology the decision was made given the patient's known 3 plus mitral regurgitation and aortic stenosis that an alpha agonist would be a more appropriate choice. the change was made. however, he became more and more acidotic over the course of postoperative day number two with the lactate rising to 23. although his wound was clean with no erythema it was opened to be certain this was not a source of possible infection. there was no purulence and the tissue appeared well perfused. his hematocrit remained in the mid 30s. he continued on pressor support and received several liters of fluid. he also received fresh frozen plasma for coagulopathy and had evidence of shock liver. around 2 o'clock he became again hypotensive and within 20 minutes went into pulseless electrical activity. cardiopulmonary resuscitation and acls protocol were instituted and he expired shortly thereafter. we were still awaiting additional culture results and concern was that he succumbed to a combination of cardiogenic and septic shock. the family was notified and they declined a postmortem examination. , m.d. procedure: continuous invasive mechanical
