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: past medical history: 1. mitral regurgitation with mitral valve prolapse. 2. chf. 3. vertigo. 4. labyrinthitis. past surgical history: arthroscopy. admission medications: 1. lasix 20 q.d. 2. atenolol 25 mg q.d. 3. aspirin 325 mg q.d. 4. os-cal one tablet q.d. 5. cozaar 50 mg per day. allergies: the patient is allergic to codeine which causes nausea. review of systems: significant for no fevers, no chills, no dental problems. history of stroke or tia. no syncope. no orthopnea, no dyspnea on exertion, no dvts, no peripheral vascular disease. positive edema in her lower legs. positive claudication. no cancer. no diabetes. family history: noncontributory. social history: she is single, lives alone. no tobacco. no etoh. laboratory and radiologic data: echocardiogram on showed an ef of 45%, right and left atrial enlargement, mitral valve showed redundantly split +3 mr, tricuspid valve 2+, tricuspid regurgitation. the laboratory values at the outside hospital revealed a white count of 6.6, hematocrit 32.6, platelet count 187,000. sodium 143, potassium 3.8, bun 27, creatinine 1.3, glucose 85. chest x-ray showed evidence of chf. ekg was sinus rhythm with lateral st changes. physical examination: general: the patient was an elderly female in no acute distress. cardiac: she had a grade iii/vi systolic murmur but was regular rate and rhythm. pulmonary: the lungs were clear to auscultation bilaterally. abdomen: soft, benign, with no organomegaly. extremities: the extremities showed right knee edema after a recent arthroscopy. the feet were warm. there was no edema, positive distal pulses. assessment/plan: this is a 79-year-old female with significant mitral valve regurgitation. will check an echocardiogram this evening to evaluate left ventricular function but the patient was preopped for cardiac surgery, mitral valve replacement, in the morning with dr. . the patient was seen by cardiology the night of admission. cardiology did a stat echocardiogram which showed mild to severe mitral regurgitation, signs of left ventricular volume overload with a reduced ef 30-40%. the recommendations were to continue diuresis, try ace or once the patient has recovered from surgery, continue atenolol and aspirin. on hospital day number one, the patient was brought to the operating room on for mvr. the patient tolerated the procedure well and was transferred to the crsu intubated, on an epinephrine drip and a propofol drip with chest tubes. the patient was weaned off the neo drip that night. the patient was on nitroglycerin drip on and off for transient hypertension. on postoperative day number one, the patient was continued on epinephrine and nipride drip. the patient was weaned on the ventilator to cpap 5/5. the patient was given 2 units of packed red cells overnight. the patient was afebrile. the patient was currently being paced. the white count was 14.5 postoperatively, crit was 32.8, platelet count 58,000. the rest of her laboratory values were within normal limits. bun 27, creatinine 1.6. the patient was given 1 liter of crystalloid. the plan was to wean epinephrine to off and nipride to off, continue chest tubes and foley. the patient was started on lopressor. on postoperative day number two, the patient's drips were weaned. the patient was on lopressor and aspirin. the patient was also receiving vancomycin. the patient was extubated without issue. the patient's vital signs were stable. the patient was on nasal cannula saturating 98%. the patient had a jump in her creatinine from 1.6 to 2.6. the patient was oliguric. vancomycin was removed. a renal consult was begun. the patient was on a lasix drip at 10. on postoperative day number three, the patient had an episode of atrial fibrillation. the patient was on dopamine drip of 2, lasix. the patient was in atrial fibrillation at a rate in the 100s. the patient's creatinine again increased to 3.9 from 2.6. the patient was given amiodarone bolus and started on an amiodarone drip. the chest tubes were removed. a hit panel was hit for a platelet count which had dropped to 29 and the hit screen was sent and the patient was taken off of heparin. a renal consult was obtained. the recommendations of the renal service were to maintain lasix drip 80 iv b.i.d., consider decreasing all renal toxic medications, sending urine cultures, checking daily weights, and a ekg to evaluate for ef. the patient was started on diurnal and lasix with little effect. on postoperative day number four, the patient was on an amiodarone drip, was afebrile, heart rate was 80, currently being paced. the patient was on 2 liters nasal cannula and was saturating 99%. the patient's creatinine again increased from 3.9 to 4.8. the patient's hit screen was negative but was continued on precautions. the patient began making a small amount of urine. renal felt that the patient would most likely need dialysis in the next one to two days and that lasix or diuretics would not alter the course of renal recovery. on postoperative day number five, the patient was transferred to amiodarone p.o., continued on lasix and lopressor, continued to be paced. the patient was started on a regular diet. the patient's creatinine once again increased from 4.8 to 5.7. after holding heparin, the patient's platelet count increased from 29 to 56. the patient had a hemodialysis line placed. the patient was dialyzed. on postoperative day number six, the patient was on a neo drip, amiodarone p.o. the patient was continued to be paced. the patient's creatinine again jumped to 6.6. the patient's swan was removed. the patient was seen by physical therapy. on postoperative day number seven, the patient had been dialyzed. the patient was on amiodarone 400 per day. the patient's hematocrit had dropped to 24.9. the patient was transfused 1 unit of blood, continuing diuresis, and continued dialysis. on postoperative day number eight, the patient was off all drips, was on lasix 80 iv b.i.d., amiodarone p.o., and aspirin. the patient continued to be paced. the patient had a decrease in bun and creatinine 36 and 3.7. the patient was found to be hit positive. the patient was transferred to the floor. upon transfer to the floor, the patient had the pace box turned off. the patient soon developed a rapid atrial fibrillation. the patient was placed again on an amiodarone drip and p.o. amiodarone was discontinued. the patient was afebrile with stable vital signs otherwise. the patient was continued on metoprolol 12.5 b.i.d. and an amiodarone drip changed to p.o. the patient was dialyzed again. on postoperative day number ten, the patient was off amiodarone drip, on amiodarone p.o., was in sinus rhythm, was afebrile. the vital signs were otherwise stable. the patient was making urine, approximately 1 liter per day. the patient had an increase in bun and creatinine 29 and 2.8. the patient was continued on dialysis. renal advised increasing lasix to 80 iv t.i.d. the patient was seen by cardiology, ep service. the recommendations were to start anticoagulation on the patient and the patient was started on an argatroban drip. the patient was also started on coumadin. on postoperative day number 11, the patient was afebrile, was still in sinus rhythm, was out of bed with physical therapy. the patient had an increase in creatinine to 3.7. the patient had a u/a which was negative. a foley catheter was placed to monitor urine output. the patient was dialyzed by renal. on postoperative day number 12, the patient was on an argatroban drip and p.o. amiodarone, p.o. metoprolol, lasix 80 iv t.i.d. the patient was in atrial fibrillation but was rate controlled. the vital signs were otherwise stable. the patient was out of bed with physical therapy. creatinine again was increased to 4.5. the patient was a physical therapy level iv, ambulating with physical therapy. on postoperative day number 12, the patient received another round of dialysis. on postoperative day number 13, the patient was started on coumadin for anticoagulation. recommendations had been that the patient's platelet count needed to be greater than 100 before coumadin could be begun. recommendations from renal were that the patient would probably require more dialysis and recommended the placement of a perma-cath. on postoperative day number 14, the patient was on argatroban drip at 0.5, p.o. amiodarone, lasix 80 iv, metoprolol 12.5 b.i.d. the patient was in sinus rhythm. the patient's scheduled perma-cath placement was cancelled due to surgeon's scheduling. the patient was continued on the argatroban drip. on postoperative day number 14, the patient was dialyzed again by renal using a quinton catheter. on postoperative day number 15, the patient was preopped for perma-cath placement. the patient was afebrile with stable vital signs, in sinus rhythm. on postoperative day number 17, the patient was brought to the operating room for placement of a perma-cath. the patient had placement of a right perma-cath in her subclavian by transplant surgery under mac anesthesia. the patient tolerated this well. the patient was transferred back to the floor. on postoperative day number 17/1, the patient was doing well, off all drips, was in sinus rhythm, on amiodarone p.o., lasix 80 iv b.i.d. the patient continued to make approximately 1 liter to a 1.5 liters of urine per night. , m.d. dictated by: medquist36 procedure: extracorporeal circulation auxiliary to open heart surgery hemodialysis venous catheterization for renal dialysis
