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: patient is a 64-year-old dialysis-dependent male without any history of angina, who experienced increasing shortness of breath for about one year prior to . patient had been noted to have noncritical aortic stenosis about five years ago during a routine cardiac evaluation. during routine followup transthoracic echocardiogram performed in , the patient was noted to have critical aortic stenosis and aortic insufficiency. the patient then underwent a cardiac catheterization, which revealed right coronary artery stenosis. the patient did complain of some lightheadedness over the prior 1-3 months. the patient denied having any symptoms suspicious for transient ischemic attacks or cerebrovascular accident. past medical history: end-stage renal disease secondary to polycystic kidney disease (on dialysis via a permacath on mondays, wednesdays, and fridays). past surgical history: 1. multiple access procedures including a-v fistulas and a-v grafts. 2. status post right nephrectomy in . 3. abdominal hernia repair. 4. partial colon resection in for diverticulosis. 5. status post failed kidney transplant in at medical center. 6. status post parathyroidectomy. allergies: patient has a severe contrast allergy and is also allergic to penicillin, gentamicin, and keflex as well as cephalosporins. medications on admission: 1. phoslo 638 mg to take five tablets 3x a day. 2. renagel 1600 mg t.i.d. 3. nephrocaps one tablet q.d. 4. colace 100 mg p.o. q.d. 5. prilosec 20 mg p.o. q.d. physical exam (): patient's physical exam was notable for carotid bruits worse on the right than on the left. his heart rate was regular with a systolic rumble. lungs were clear. abdomen was soft and nontender with some well-healed surgical scars at the midline, right lower quadrant, and subcostally. there were no palpable masses. patient had left groin permacath. patient had some venous stasis changes of both lower extremities, but with palpable dorsalis pedis pulses bilaterally. the patient also had a right arm a-v graft in place. hospital course: patient was admitted to the on , and underwent an aortic valve replacement with #25 valve. the patient also underwent coronary artery bypass grafting from the saphenous vein graft to the right coronary artery. the procedure was performed without complications, and the patient was as is routine, transferred to the cardiac surgery intensive care unit while intubated. the patient was extubated awhile after arriving to the intensive care unit. at the time, the patient was alert and moving all extremities. his blood gases were good and appeared in no distress. within a few minutes after being extubated, however, the patient decompensated and became apneic with a decrease in his oxygen saturations. the patient required reintubation and was evaluated by the neurology service. following evaluation, the patient's event was believed to be secondary to respiratory arrest contributed by the need to be supine with his groin line as well as his previously undiagnosed history of sleep apnea. patient showed no neurological deficits after the reintubation and quickly returned to baseline neurologic function. no immediate imaging was deemed necessary. a bronchoscopy was performed revealing minimal mucus and essentially clear airways. patient underwent hemodialysis on postoperative day #1. patient was ultimately extubated on postoperative day #2 without event. on postoperative day two, the patient underwent another session of hemodialysis, and was noted to have frequent premature atrial contractions subsequently changing to atrial fibrillation at a rate of 140. the patient was bolused with amiodarone and started on a drip. the patient returned to sinus rhythm shortly after. the patient remained on levophed drip. the patient had been empirically started on levofloxacin antibiotic regiment for possible pneumonia given some thick copious mucus. this patient was afebrile and had a normal white count. over the following few days, the patient had brief episodes of atrial fibrillation, though revert to sinus rhythm with amiodarone boluses. a heparin drip was started and plans were made for anticoagulation with coumadin. the patient remained on a levophed drip to support his blood pressure with goal systolic blood pressures in the 90s-100s. patient was ultimately weaned off of his levophed on postoperative day #7. his systolic blood pressure remained low mainly in the 90s, but the patient seemed to tolerate this well. the patient was transferred out of the icu on postoperative day #8. the patient remained on hemodialysis and ultrafiltration to try and offload some of the volume the patient had gained intraoperatively. patient was ultimately started on coumadin on . within three days, the patient's inr was 2.5 following doses of 2 mg, 2 mg, and 1 mg. patient completed a 14-day course of levofloxacin and was started on clindamycin for some lower extremity erythema. patient was noted to have small stage ii decubitus ulcer on , and wound care consult was requested with the recommendation made for duoderm gel and thin duoderm wafer dressings to the wound as well as frequent positioning changes. patient had remained in normal sinus rhythm with no further episodes of atrial fibrillation since transferred from the intensive care unit. he was on amiodarone by mouth. by postoperative day 20, the patient was deemed ready for discharge to rehab facility. but by the time of discharge, the patient's pain was well controlled and his respiratory status was stable. his estimated dry weight was 87 kg, and on the day prior to discharge, had a predialysis weight of 94.1 kg. four kg of fluid was taken off that day. patient had been seen by physical therapy while in house and on ambulation remained somewhat unsteady and weak, requiring the assist of two people for safe ambulation. the patient's sternal incision was healing well with steri-strips in place. patient also had some left lower extremity incisions, which appeared to be healing well with a few small blisters. a transthoracic echocardiogram had been performed on approximately to confirm the absence of thrombus in the patient's heart. the transthoracic echocardiogram revealed no such thrombus, and the decision was made to cease further anticoagulation on the patient and his coumadin was discontinued. the benefits and risks of further coumadin therapy had been reviewed, and further treatment was deemed unnecessary given that the patient had been in normal sinus rhythm for much of his hospitalization and that his atrial fibrillation could have been attributed to his significant fluid overload immediately after the surgery. discharge condition: stable. discharge diagnoses: 1. aortic stenosis. 2. aortic insufficiency. 3. end-stage renal disease. 4. coronary artery disease. 5. atrial fibrillation. 6. sacral decubitus ulcer. 7. lower extremity cellulitis. 8. respiratory arrest. 9. sleep apnea. followup: patient is to followup with dr. within 1-2 weeks following discharge. the patient is also to followup with his primary care physician 1-2 weeks following discharge. the patient will need to setup an appointment with his outpatient cardiologist in weeks following discharge. the patient will also need to setup an appointment with a sleep clinic for further evaluation of his sleep apnea. discharge medications: 1. amiodarone 200 mg p.o. q.d. 2. aspirin 81 mg p.o. q.d. 3. dulcolax 10 mg p.r. q.d. prn. 4. calcium acetate 1334 mg p.o.
