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. aortic valvular disease. 2. hypertension. 3. hypercholesterolemia. 4. status post left knee surgery. 5. status post cholecystectomy. 6. diabetes mellitus, diet-controlled. preoperative medications: 1. aspirin 81 mg p.o. q.d. 2. lescol xl 80 mg p.o. q.d. 3. atenolol 25 mg p.o. q.d. allergies: lipitor and shell fish. social history: the patient is a 20 pack year smoker. physical examination on admission: vital signs: stable. heent: nc/at, perrla, eomi. neck: supple. no lymphadenopathy or thyromegaly. carotids: 2+ bilaterally with audible murmur radiating to the neck. lungs: clear anteriorly and posteriorly. cardiovascular: regular rate and rhythm without rub, loud systolic ejection murmur. abdomen: obese, soft, nontender, without masses, or hepatosplenomegaly. extremities: without clubbing, cyanosis or edema. the pulses were equal bilaterally. hospital course: the patient was admitted on for surgery. the patient was taken to the operating room for an aortic valve replacement with a . mechanical valve. the patient tolerated the procedure well. please see the operative note for further details. in the operating room, the patient was noted to have an ejection fraction of greater than 55%. the patient was transferred to the intensive care unit in stable condition. shortly after arriving in the intensive care unit, the patient became hypotensive and unresponsive to volume resuscitation or boluses of epinephrine. the patient developed pea and chest compressions were begun. dr. was at the bedside. shortly after the patient was in full arrest. the decision was made to reopen the patient's chest at the bedside. prior to doing so, a transesophageal echocardiogram was obtained which showed no aortic dissection. the chest was opened by dr. and dr. , and internal cardiac massage was begun. the decision was made to take the patient back to the operating room. in the operating room, the patient was put back on bypass and an intra-aortic balloon pump was placed. the mediastinum was explored. no evidence of tamponade or bleeding was found. no evidence of aortic dissection. the patient was resuscitated in the operating room and was weaned from the peripulmonary bypass machine successfully and again transferred back to the intensive care unit in stable condition. the patient had early chest tube output her first postoperative night requiring reversal of her coagulopathy with blood products. in the early morning of postoperative day number one, the patient had multiple runs of nonsustained vt and was started on amiodarone. after the amiodarone was started, the ventricular tachycardia decreased. the patient was on milrinone for inotropic support which was weaned to off on postoperative day number one. the patient's intra-aortic balloon pump was weaned down. by the evening of postoperative day number one, the patient's hemodynamics had decreased and the intra-aortic balloon pump wean was discontinued. the patient had been weaned and extubated from mechanical ventilation which she tolerated well. on the night of postoperative day number one, the patient's hemodynamics again decreased and the milrinone was restated. on postoperative day number two, the intra-aortic balloon pump was removed successfully. the patient tolerated this well. it should be noted that the patient had awoken immediately postoperatively without any neurological deficits, moved all extremities equally, and was neurologically intact. on postoperative day number two, the patient's milrinone was again weaned down. the patient began receiving lasix for diuresis as the patient's chest x-ray on physical examination showed that she had volume overload. by postoperative day number three, the milrinone was weaned to off. the patient had been on levophed for maintenance of blood pressure that was weaned to off. the patient had been paced through the epicardial pacing wires, a paced, for improvement of her cardiac index. the patient had been tolerating diuresis. on postoperative day number four, the patient was started on coumadin for anticoagulation. the patient's pacing wires were removed without difficulty on postoperative day number five. the patient's pressors had been weaned to off. on postoperative day number five, the patient was transferred from the intensive care unit to the regular floor. the patient began walking with physical therapy. anticoagulation with heparin was started and by postoperative day number six, the patient had completed a level v walking 500 feet and climbing one flight of stairs with physical therapy, and was cleared from a clinical standpoint to go home. the patient was not adequately anticoagulated on coumadin yet. by postoperative day number eight, the patient's inr had reached 2.0 and she was cleared for discharge to home. discharge physical examination: vital signs: t maximum 98.3, pulse 66, in sinus rhythm, blood pressure 122/47, respiratory rate 16, saturation on room air 96%. neurologically, the patient is awake, alert, oriented times three. the neurological examination was nonfocal. cardiovascular: regular rate and rhythm, positive click, no murmur. respiratory: lungs were clear bilaterally anteriorly and posteriorly. gi: the abdomen was obese, positive bowel sounds, soft, nontender, nondistended, tolerating a regular diet. extremities: there was 2+ pitting edema, warm, good distal pulses. sternal incision: staples are intact. there was a minimal amount of drainage at the distal portion of the incision. there was no erythema. the sternum was stable. laboratory/radiologic data: white blood cell count 6.2, hematocrit 28, platelet count 222,000. sodium 141, potassium 4.4, chloride 104, bicarbonate 27, bun 17, creatinine 1.2, glucose 105. discharge medications: 1. lasix 40 mg p.o. b.i.d. times seven days. 2. 40 meq p.o. b.i.d. times seven days. 3. colace 100 mg p.o. b.i.d. 4. zantac 150 mg p.o. b.i.d. 5. enteric coated aspirin 81 mg p.o. q.d. 6. levofloxacin 500 mg p.o. q.d. times ten days. 7. amiodarone 400 mg p.o. q.d. 8. percocet 5/325 one to two tablets p.o. q. six hours p.r.n. 9. lescol 80 mg p.o. q.d. 10. coumadin 7.5 mg p.o. q.d. on , and . on , the visiting nurse is to draw a pt/inr and call the results to dr. office. dr. will follow the coumadin and dose it according to the inr. follow-up: the patient is to follow-up with dr. in one week. the patient is to follow-up with her primary care physician, . , in two weeks. the patient is to return to ii for staple removal in two weeks. the patient is to follow-up with dr. in three weeks. disposition: the patient is to be discharged to home in good condition. discharge diagnosis: 1. aortic stenosis and aortic regurgitation, status post aortic valve replacement with a . . 2. postoperative cardiac arrest. 3. hypertension. 4. hypercholesterolemia. 5. diabetes mellitus, diet-controlled. , m.d. dictated by: medquist36
